前段时间买了一个随身wifi,用了一个月,9.9一个月120G  还是挻划算的。但是用的过程中发现这个东西WAN口倒是能获取到ipv6的地址,但是LAN却不支持ipv6,分配给客户端的地址都是ipv4的,系统提供的界面找不到跟ipv6相关的东西,问了客服也说不支持ipv6。这就造成无法访问家里的NAS ,因为NAS是用的ipv6  。因此拆机看看是不是能刷机什么的,如果不能刷机解决,那就得买个高通410方案的刷openwrt或者其它支持ipv6的固件了

还有TI的这个DSP   TLV320AIC3xxx  这个文档写白非常清楚,但不适用于tas5805.


一般 AIC31 系列为 16 位系数,而 AIC32 系列为 24 位系数,具体可以查看对应的数据手册。在
Resolution 位置设定对应的系数位数并回车,下面的窗口就显示出对应的滤波器情况,传输函数和对
应的参数的数值。这些数值即可用于写入 CODEC 内部对应的系数寄存器。数值的排列和窗口上面所
列的传输函数是对应的,比如对于两阶滤波器,有 N0, N1, N2 和 D1, D2 分别对应列出的 5 组数值。
而对于一阶的滤波器,N2 和 D2 为 0,所以只有三个系数,对应 N0, N1 和 D1。这些数值的定义和
CODEC 的数据手册中的定义是相对应的。

文档最后还给出了用程序计算 EQ 的参数的代码
最后举例说明在程序中怎样实时计算 EQ 的参数。通常 EQ 需要根据给定的频率带宽和增益来实时调整
的,其他类型的滤波器一般没有这种需求。在文档 SLAA447 中,作者给出了公式的推导方法和
Matlab 的工具生成的参数的转换方法,没有介绍怎样用代码将这些东西实现并联系起来,这里不在重
复 SLAA447 中讲的变换过程,直接给出经过测试验证正确的代码和简单注释供参考,从代码和注释来
看,转换的过程更加清晰和直观。

1.第一种是USB Gadget Audio Class 1.0 Legacy
这种方式需要有实体的声卡,就是加载驱动时指定那个放音设备/dev/snd/pcmC1D0p,不指定的话,放音设备是/dev/snd/pcmC0D0p 录音设备是/dev/snd/pcmC0D0c,驱动加载完,不需要其它操作,就可以直接使用了。

但是问题来了,但是这种方式会独占那个声卡,其它程序是无法再访问那个设备了,我需要程序和USB混音,修改asound.conf也没用

2.第一种是USB Gadget Audio Class 1.0
这种方式在驱动加载后,系统会多出一张声卡,包含一个放音,一个录音设备,前边那种是不会出现任何设备的

modprobe g_audio.ko c_srate=48000 c_ssize=2 c_chmask=3 #48k 16bit 2ch

[   72.123305] g_audio gadget: high-speed config #1: Linux USB Audio Gadget
名字也叫 AC INTERFACE ,如果需要改名字,是在uac1.c里边修改,电脑播放音乐

执行 arecord -D hw:2,0 -f dat -vv | aplay -D hw:1,0 -f dat 可以听到电脑播放的音乐,这种方式好像挻符合要求的

但是问题又来了,这种方式需要电脑或者手机一直播放着音乐才行,否则过一会I/O错误,录音进程直接退出,电脑端正常播放不受影响,但是板子肯定没音了,录音进程已经退出了,重新执行命令才可以。问题是我怎么知道用户什么播放呢?录音进程录不到东西就直接能出了,不能一直在后台运行
2023-02-17_145650.png

3.USB Gadget Audio Class 2.0
既然上边那种方式也不行,那再试试2.0,驱动加载完成后,同样会多出2个声卡,设备管理器里会出现一个叫 Source/Sink的设备,尴尬的是设备启动不了,但是在Linux或者手机上是正常的,系统是win10 build1909 已经自动2.0驱动了,其它操作跟上边是一样的,也是需要一直录音才能使用,不放音时 录音进程直接IO错误面退出
2023-02-18_112640.png

最后,请大神支点招,如何解决电脑在没播放音乐时,录音进程退出问题?不放音乐时 一直传输0不就行了吗,这样录音也可以一直进行下去了

屏幕休眠了

echo 1 > /sys/class/graphics/fb0/blank 是使能休眠

如果想屏幕永不休眠,在UBOOT启动参数bootargs中增加  consoleblank=0

@shaoxi2010
1.大佬,能指点下设备要怎么改吗,直接改了源码也不行
2.spi是单线,感觉还是SPI速度太慢,不知道内核启动后SPI速度怎么查看
3.启动后我查看熵池在3000左右,好像也不低,然后添加了havged ,时间基本没变,另外2个办法还不知道怎么弄

#71 Re: 全志 SOC » F1C200 linux LVGL双缓冲支持 » 2022-05-08 22:47:39

我在f1c200s上也试了,感觉比起framebuffer 帧率没有提高多少,在f1c100s上由于内存不够,第一次是可以执行的,再执行就申请不到内存了无法正常显示了

#75 全志 SOC » F1C100S SPI-NOR 启动 修改SPI 默认的1MHZ 频率不生效? » 2022-05-06 22:28:44

xfdr0805
回复: 3

发现在uboot在从spi-nor启动时是用1MHZ加载数据的,读取5M kernel 要5秒多 速度太慢了
使用sf probe 0 50000000 不生效,速度没变化

然后看了下代码,将
#define SPI_DEFAULT_SPEED_HZ 50000000 
#define CONFIG_SF_DEFAULT_SPEED 50000000
这2个宏都修改了,打印出来速度是设置成50MHZ了,貌似没生效,依然是1MHZ速度加载

uboot新的DM_MODEL太复杂还看不懂,然后不使用DM_DRIVER,又出现
Invalid chip select 0:0 (err=-19)
Failed to initialize SPI flash at 0:0

参考了这一篇文章

新版本支持V8 也支持V7,也可以试试另外官方的https://squareline.io/

编译InfoNes 跑了一下  https://github.com/nejidev/arm-NES-linux  声音听着难受
颜色问题 一开始以为是RGB5565 转换后还是颜色不对, 原来InfoNes默认输出的是RGB555 格式的

static DWORD rgb555_2_argb888(WORD color)
{
    DWORD c;
    unsigned char red;
    unsigned char green;
    unsigned char blue;

    red = ((unsigned char)(color >> 10)) << 3;
    green = ((unsigned char)(color >> 5)) << 3;
    blue = ((unsigned char)color) << 3;

    c = (red | c) << 16 | (green | c) << 8 | (blue | c);

    return c;
}

建议你检查消息循环,空闲回调那些地方。这个卡顿跟性能没关系,我用蜗牛唐的192MHZ arm9带7寸屏幕都跑得比你这快,更别说你这U的主频那么高了。

我使用的是800×480 32bit全屏缓冲区,有绘制背景图片,总感觉lvgl绘图速度上不去,LVGL要绘制完才更新,
主线程就是这样,你说的消息循环,空闲回调,这些是LVGL自动处理的吧
while (1)
    {
        signal(SIGINT, sighandle); //设置信号处理函数
        usleep(lv_task_handler() * 1000);
    }

发现软件做再多优化都没有把DRAM_CLOCK频率提高来的明显,CPU用默认频率,DRAM设置480MHZ 帧率提高3倍左右,已经很流畅了,用的全尺寸单缓冲区
软件上把freetype,去掉直接取模,一些图标也是取模,界面切换逻辑修改为先清空再重新绘制,之前是把界面全部绘制出来隐藏起来,切换时再显示出指定的界面,对性能低的MCU不合适,内存占用也大,最后就是加上多线程。接下来就是优化启动时间,缩小镜像体积了

你这估计是刷图方式有问题,开启了整屏刷图的模式,要选择局部刷。注意下刷新周期

是开启了整屏刷图,不过跟这个关系好像不大 ,目前发现DRAM_CLOCK 频率对刷图影响非常大,默认是312MHZ  我改到400MHZ 帧率提升非常明显,再高就不稳定了,CPU 720MHZ 对帧率影响不大,只是CPU使用下降了

FrameBuffer 还是使用32位的,为的是让LOGO持续到APP启动 
DRM可以改为16bpp还不知道如何让logo持续  drm从fb继承时好像会重新初始化

使用16bpp 内存小一半,传输数据也少一半,刷新速度应该更快吧

软件:Linux 5.4  framebuffer 32bpp + LVGL8 + freetype

目前LVGL 位深是32  硬件连线是RGB565  暂时当成RGB888来用, 修改了设备树,format=r5g6b5,还是一样,不知道如何将framebuffer 修改为16bpp?单缓冲,双缓冲,全屏缓冲都试过了,目前感觉是LVGL绘图跟不上,图片,字体资源都放在外边,因为用fb-test-rect或者编译widgets_demo 帧率还可以。

请教坛里的大佬们,如何将framebuffer 修改为16bpp或者提高刷屏速度?

直接拿原版键盘开刀,在26键基础上修改最省事,只需要简单修改一下布局就可以了,使用时可直接替换原来的keyboard即可,效果如下图

过程参考了一个输入法,忘记哪找的了,把原版也一并放上
在原版基础上做了一点修改,统计了一下,有7451个汉字可以输入
修复必须全拼才能打出字的问题,现在只需要输一个字母即可出现候选字
将原来的候选按钮分离出来,方便设置候选词字库,键盘符号不受影响
原版如果设置其它字库,键盘一些符号会不显示,需要将字库与fontawesome合并才能显示符号

程序肯定有不足的地方,最后附上代码,大家一起改进

其实没花多少精力 一上午就完成了 因为有大神已经完成了gerber解析并渲染了 我只是读取座位号及数量然后从坐标文件里获得每个元件的坐标并生成gerber绘图语句就完了 只有这么一丢丢的工作量  比起gerber解析渲染 可以忽略

开发背景

一直一来,在开发完新样品做样机的时候,手工贴片非常痛苦,板子简单还好,如果板子复杂且样机数量又多(一般10台以内),那真是贴的眼疼胳膊酸啊,在贴片过程中最耗费时间的就是在密密麻麻的丝印图上找元件座位号了,所以如果有什么工具能一下子找到并能图形化标注出来位置,那将大大加快贴片的速度,也不用闻那么长时间的锡膏散发出来的有毒气体了。

灵感来源

之前在用Kicad设计板子的时候,有一款插件不得不提一下,就是InteractiveHtmlBom,这款插件可以生成一个交互式BOM的文件,可以在浏览器里打开,图形化展示出来各个元件位置,手工贴片非常方便
image1.png
这正是我想要的效果,但是这个插件只适合用在Kicad或者LCEDA里,其它软件使用不了,而且还得是源代码才能生成交互式BOM,只能自己开发了,于是就有了这个软件

实现原理

由于没有源文件,要实现这种效果,需要有BOM表,Gerber,及坐标文件,这些是工厂批量生产的最基本的东西,都会提供的。
原理:根据BOM表获取同一种元件的座位号,再从坐标里件里获取每一个元件的坐标,然后生成每一个元件的gerber绘图语句,最后就是渲染gerber丝印图并在上边标识出来

Gerber文件解析

Gerber文件要是自己写,还是比较复杂的,网上已有很多开源的Gerber文件解析的库,就不重复造轮子了,这里使用了miltonneal54大神开源的GerberVS库,我测试了一下,已经相当完善了,测试了一些产品的gerber 基本没问题。

BOM表解析

BOM是excel格式的,这里使用开源的NPOI进行BOM表的读取,还是比较简单的

workBook = new XSSFWorkbook(tbx_bom.Text);
ISheet sheet = workBook.GetSheetAt(0);//"PCB 部分"
//计算总行数
int lastNum = sheet.LastRowNum;
Console.WriteLine("总行数:" + lastNum);
//从第1行开始
//Console.WriteLine(sheet.GetRow(3).GetCell(1).StringCellValue);
dataGridView1.Rows.Clear();
for (int i = 2; i < lastNum; i++)
{
    if (sheet.GetRow(i) != null)
    {
        //Console.WriteLine(i + " ---> " + sheet.GetRow(i).Count());
        dataGridView1.Rows.Add();
        for (int j = 0; j < 10; j++)
        {
            if (sheet.GetRow(i).GetCell(j) != null)
            {
                if (sheet.GetRow(i).Cells.Count > 10)
                {
                    //dataGridView1.Rows[i].Cells[j].Value = sheet.GetRow(i).GetCell(j).StringCellValue;
                    switch (sheet.GetRow(i).GetCell(j).CellType)
                    {
                        case CellType.Numeric:
                            //Console.WriteLine(j + " ---> " + sheet.GetRow(i).GetCell(j).NumericCellValue);
                            dataGridView1.Rows[i - 2].Cells[j].Value = sheet.GetRow(i).GetCell(j).NumericCellValue;
                            break;
                        case CellType.String:
                            //Console.WriteLine(j + " ---> " + sheet.GetRow(i).GetCell(j).StringCellValue);
                            dataGridView1.Rows[i - 2].Cells[j].Value = sheet.GetRow(i).GetCell(j).StringCellValue;

在图形中渲染位置

根据坐标生成对应的gerber绘图语句,比如画一个圆点,能标识出即可

//获取座位号
Console.WriteLine(dataGridView1.Rows[e.RowIndex].Cells[7].Value);
string location = (string)dataGridView1.Rows[e.RowIndex].Cells[7].Value;
string[] loc;
StringBuilder sb = new StringBuilder();
sb.Append("G04 Sonavox auto mark smd commpent helper *\r\n");
sb.Append("G04 Draw by:101367 *\n");
sb.Append("%MOIN*%\n");//单位选择
sb.Append("%FSLAX55Y55*%\n");//坐标系选择
//sb.Append("%ADD12R,0.050X0.050X*%\n");//画圆点
sb.Append(string.Format("%ADD11C,{0}*%\n", numericUpDown_size.Value.ToString()));//画圆点
sb.Append("\nG54D11*\n");//选择自定义光圈
if (location != "")
{
    loc = location.Split(',');
    bool find = false;
    foreach (string s in loc)
    {
        find = false;
        foreach (Placement p in pst)
        {

            if (s == p.Symbol)
            {
                find = true;
                Int32 xpos = Int32.Parse(p.X_pos) + (Int32)numericUpDown_x.Value;
                Int32 ypos = Int32.Parse(p.Y_pos) + (Int32)numericUpDown_y.Value;
                xpos = xpos * 100;
                ypos = ypos * 100;
                sb.Append(string.Format("X{0}Y{1}D03*\n", xpos, ypos));//标识位置
                Console.WriteLine(string.Format("Top SMD:{0}--->X:{1} Y:{2} R:{3}", s, p.X_pos, p.Y_pos, p.Rotation));
                //break;
                continue;//跳过剩下的代码,继续执行循环
            }

        }

                    sb.Append(string.Format("X{0,0.00}Y{1,0.00}D03*\n", xpos, ypos));//标识位置

                }

        if (find == false)
        {
            MessageBox.Show(s + "的坐标未找到,请确认!!!\r\n可能是座位号不正确或者在MI部分");

软件界面

图形标记目前只支持加点,可以很容易添加方框,箭头等符号
image4.png
软件以坐标文件中第一个位置为参照来计算偏移量的,需要填入实际坐标才可以计算出偏移量,如果坐标没有偏移,则无需计算,贴完的可以标记为绿色背景,取消即为默认背景

源码如下

目前代码只适合解析我们cadstar导出的文件,这个EDA国内用的不多,这里给出源码,简单修改下就可以解析其它格式的BOM及坐标文件了,有需要的朋友可以参考

奔跑的蜗牛-加油 说:

貌似安信可的 A9G 的 CSDK 里面也是用了 RDA8910的芯片,不知道能不能使用上面的教程。

安信可的 A9G 模块使用的是RDA8955  只支持2G网络的

确定要使用的GPIO,这里需要使用带外部中断的引脚,否则驱动注册失败 request:-22

这是我的设备树配置

 ir_gpio {
 compatible  = "gpio-ir-receiver";
 gpios = <&pio 1 5 GPIO_ACTIVE_LOW>; /* PB5 */
 /*active_low = <1>;*/
 linux,rc-map-name = "rc-tevii-nec";
 status = "okay";
};

内核里修改

Device Drivers > Remote Controller support >

 [*]   LIRC user interface                                             
 [*]   Remote controller decoders  --->                                
 [*]   Remote Controller devices  --->                                 
       <*>   GPIO IR remote control 

驱动成功加载会有如下输出

[ 1.223257] IR NEC protocol handler initialized
[ 1.227806] IR RC5(x/sz) protocol handler initialized
[ 1.232985] IR RC6 protocol handler initialized

[ 1.282144] input: gpio_ir_recv as /devices/platform/ir_gpio/rc/rc0/input3

此时查看/dev/input目录下,会有如下显示:

 # evtest 
 No device specified, trying to scan all of /dev/input/event*
 Available devices:
 /dev/input/event0:      1c22800.lradc
 /dev/input/event1:      rotary@0
 /dev/input/event2:      ns2009_ts
 /dev/input/event3:      gpio_ir_recv

此时如果用evtest测试按键是没有任何反应的,需要修改对应的驱动,此问题先留在这里
不影响后续操作

后来查资料,发现可以用lirc里的工具去测试硬件是否OK,测试之前要先修改默认配置文件,不修改的话,同样没反应

 # vi /etc/lirc/lirc_options.conf 
 driver          = default
 device          = /dev/lric0
 修改这2行就可以,里边driver默认是uinput,device默认是auto
 再次测试就有反应了
 # mode2 -m -d /dev/lirc0
 Using driver default on device /dev/lirc0
 Trying device: /dev/lirc0

从这结果上可以明显的看出这些数值代表脉冲宽度,单位是us

使用irrecod -f -d /dev/lirc0 –disable-namespace来录制配置文件
录制完成后放到 /etc/lric/liricd.conf.d/下边
!注意,这里录制的结果不准确,需要借助上边的命令来获取每一个按键的值,这里只是借用一下配置文件的格式,里边的数字是右对齐

接下来使用irw来验证刚才录制的是否正确

 # irw
 lircd-0.10.1[432]: Notice: accepted new client on /var/run/lirc/lircd
 lircd-0.10.1[432]: Info: [lirc] protocol is enabled
 0000000000000001 00 Power elac
 0000000000000002 00 BT elac
 0000000000000003 00 Vol+ elac
 0000000000000004 00 Vol- elac

 000000000000000a 00 Opt1 elac
 000000000000000b 00 Opt2 elac
然后在/etc/lirc/目录下创建lircrc配置文件或~/.lircrc
格式如下

 begin
         prog = irexec
         button = Power
         repeat = 0
         config = echo "power"
 end
 begin
         prog = irexec
         button = Vol+
         repeat = 1
         config = amixer -M -c 0 sset 'Headphone',0 1%+ > /dev/null
 end
 begin
         prog = irexec
         button = Vol-
         repeat = 1
         config = amixer -M -c 0 sset 'Headphone',0 1%- > /dev/null
 end
保存

最后就是使用irexec来进行各种操作了,无需编程,到这里可以自由发挥了,想要集成到代码里也很简单,看下图

 # irexec

通过socket使用lirc,不需要引入任何文件,可以方便的集成到代码里,就是上述第三种方式

struct sigaction act;
char buf[128];
struct sockaddr_un addr;
typedef struct
{
    char addr[32];
    char code[8];
    char type[16];
    char name[16];
} IRW_DATA;
IRW_DATA irw_data;
act.sa_handler = sigusr1;
sigfillset(&act.sa_mask);
act.sa_flags = SA_RESTART; /* don't fiddle with EINTR */
sigaction(SIGUSR1, &act, NULL);
addr.sun_family = AF_UNIX;
strcpy(addr.sun_path, "/var/run/lirc/lircd");
fd_lircd = socket(AF_UNIX, SOCK_STREAM | SOCK_NONBLOCK, 0);
if (fd_lircd == -1)
{
    printf("Create socket failed\n");
}
if (connect(fd_lircd, (struct sockaddr *)&addr, sizeof(addr)) == -1)
{
    printf("Cannot connect to socket %s\n", addr.sun_path);
}
while (1)
{
    // lircd
    if (read(fd_lircd, buf, 128) > 0)
    {
        LOG_D("%s\n", buf);
        char *p = strtok(buf, " ");
        int i = 0;
        while (p)
        {
            // LOG_D("%s\n", p);
            if (i == 0)
                strcpy(irw_data.addr, p);
            else if (i == 1)
                strcpy(irw_data.code, p);
            else if (i == 2)
                strcpy(irw_data.type, p);
            else if (i == 3)
                strcpy(irw_data.name, p);
            p = strtok(NULL, " ");
            i++;
        }
        LOG_D("%s\n", irw_data.type);
        switch ((uint8_t)strtol(irw_data.addr, NULL, 10))
        {
        case Vol_up:
            rotary_encoder_handler(&u8g2, -1);
            break;
        case Vol_down:
            rotary_encoder_handler(&u8g2, 1);
            break;
        case Play:
            rotary_encoder_button_handler(&u8g2);
            break;
        case Bt:
            printf("BT button\n");
            break;
        }
    }

1.从此处下载sox官网http://sox.sourceforge.net 解压后新建一个autoconfig.sh脚本
这里使用了绝对路径,使用相对路径在最后链接时找不到文件,所以直接使用了绝对路径,里边的一些插件如果不需要可以去掉,我也一起打包传上来,另外这手动编译依赖可真烦那,只能缺哪个下载哪个再编译哪个最后才能给链接出来,跟buildroot里3S钟把sox勾选上完事编译完事相比,手动编译估计得3小时 ^*_*^,简直弱爆了,附件在最后,是修改好的源文件,稍做修改即可编译。

2.编译完成后执行make install 即可,安装目录就是上边指定的,拷贝到开发板或者NFS目录下

3.先来播放音乐试一下

play -V -r 48000 -b 16 -c 2 -n synth sin 1000 vol 0db  #产生正弦波
play -V -r 48000 -b 16 -c 2 -n synth pink 1000 vol 0db #产生粉红噪音

6.从 20Hz 到 20kHz 的频率扫描,持续时间为 30 秒 音量0 重复10次

play -V -r 44100 -b -c 2 -n synth 30 sin 20+20000 vol 0db repeat 10

7.20-10kHz 和 1kHz-20kHz 双频扫描

play -V -r 44100 -n synth 30 sin 20+10000 sin 1000+20000 remix 1,2 channels 2

8.sox功能还有很多,不过这几个功能目前已经满足我的需要了,其它高级玩法就留给大家了

TeveT 说:

无法用dbus 发送事件去上下曲 ,应当是bluealsa 的插件没打开

可以使用dbus发送事件,只是不太清楚,在蓝牙连接后自动生成的那个event是干什么的,看起来像个键盘

#121 Re: 全志 SOC » 分享在V3S RTL8723DS 上调试蓝牙音频的一点经验 » 2021-07-30 09:50:37

蓝牙连接成功后,自动生成了一个event3  通过这个为什么不能控制手机呢?还是说我的手机变成了一个输入设备,按手机音量加减 也没事件输出啊?

3. UART2默认速率是9600可以使用cat /dev/ttyS2来测试串口是否正常
4. 使用rtk_hciattach绑定uart端口
        rtk_hciattach -n -s 115200 /dev/ttyS2 rtk_h5 &
`注意这个过程需要加载固件才行,如果固件不存在、不匹配或者错误就会失败。需要把固件放到提示的位置`
5. 固件及配置文件加载完后

12. 通过AVRCP来控制手机上一曲,下一曲等 https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/media-api.txt
    `注意这里的蓝牙地址是你手机的,不是蓝牙模块的,因为要控制的是你的手机进行一一曲,下一曲的,地址不对会提示错误,就是这个原因,另外我测试除了不能调节音量外,其它的都能控制,不知道为什么?`
        Error org.freedesktop.DBus.Error.UnknownObject: Method "Previous" with signature "" on interface "org.bluez.MediaControl1" doesn't exist

13. 另外在蓝牙连接成功时会在/dev/input/目录下注册一个event3

        B: REL=0

        我偿试过使用sendevent 去操作/dev/input/event3 但是没有任何反应,不知道能不能这样操作?
        # ./sendevent /dev/input/event3 1 116 1
        # ./sendevent /dev/input/event3 0 0 0
        # ./sendevent /dev/input/event3 1 114 1

14. 至此,BLUETOOTH,DLNA,AIRPLAYER都可以通过Alsa声卡一起同时播放了

此项目包含完整代码及原理图,使用W5500通过SPI连接,里边有MODBUS 主站,从站,webserver tcpserver,can
这个配置界面就一个比较简单,webpage采用了gzip压缩,参数都是POST 采用Ajax传递,参数解析本来是用cJSON的,后来取消了,自己定义数据来解析的,MCU内存只有20KB,太小了
(PS:开始玩Licheepi有几个月了,现在感觉V3S 64M内存好大,都不知道咋用了)
