请问使用7789的屏，反色咋整？系统固件可否分享？

抱歉挺久才看到，最近没上来水贴，在st7789.c里面有一行代码屏蔽掉就好，中文翻译就是开启反色显示，哈哈哈

树莓学LINUX · 全志 SOC

看到楼主的帖子我不禁想到了我第一次点亮v3s的心情，双端显示（串口和屏幕同时显示信息）需要在内核中开启一行代码，具体的在家里电脑，需要的话回去发给你方法，现在在摸鱼:p

树莓学LINUX · 全志 SOC

我也是新手做 3s还是很简单的，无非就是几组供电（1.2，1.8，3.0,3.3，好像还有2.5？），供电不要用LDO，用DC转DC，屏幕简单的话用SPI，驱动是st7789，复杂一点是用mipi lcd 其余的按照别的大佬做好的抄就可以了。群里v3s的小电脑的资料还是很多的。

你好，我今天试了一下，用buildroot2019可以编译gstreamer-mm，但是我的还是会报错，想问一下这个你弄好了吗?

小白完成了v3s_linux小电脑的制作，在这个过程中，很有收获。
linux硬件部分包括：

1、板载USB_hub，摄像头网卡均使用外置，所以足够的USB接口十分重要。
2、使用TFT_LCD显示屏幕，屏幕驱动芯片为ST7789.
3、使用TC8002D功放芯片驱动喇叭（未实现，原因未知，仍在排查）
4、串口部分使用CH340N，引脚较少，节省体积。
5、电源部分3.3,1.8,1.2使用sy8088aac DC-DC芯片，供电量比较给力，不发热。
6、增加用户LED与串口指示灯。
7、ADC按键。
8、使用四层PCB。

用镊子触碰功放芯片的IN-，就是你接HP_L的那个引脚有沙沙响的声音吗

是不是我板子上的有些引脚浮空有影响，我把SD卡插在dock板子上有声音

上图是我的音频部分电路图，芯片使用的是pin to pin 的替代芯片TC8002D

我的设计就是LDO，5V转3.3V 3.3V转1.8V 3.3V转1.2V 可以正常使用，我也遇到过1.2V被拉成了0.8V,后面重新吹了一下就可以了

请问您用的LDO 1.2V最大输出电流多大，我用两个LDO并联上去，电压没有被拉低了，但是还是不正常

老大，还有一个问题就是，我在设备树里面添加了LRADC的设备树，在make编译时显示这块有语法错误，然后我发现好几个版本的sun8i-v3s.dtsi内容都有不一样，不知道是不是这里的问题，如果方便的话，可否发一下你的这个文件

我遇到了一个问题，我的zero外接的TFT显示器，现在只能是内核启动完成后屏幕进入显示，请问怎样在串口和屏幕上都显示内核启动过程

我猜是修改uboot中的

#define CONFIG_BOOTARGS      "console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw  vt.global_cursor_default=0"

可是我不知道如何修改，

用电大的换成dcdc就行，其他的用小封装的ldo就行。

板子上几乎不存在用电量大的，我的想法是 5V转3.3V 3.3V转3.0V 3.0V转1.8V 1.8V转1.2V 这样的话，估计发热也不会很严重

没错，这就是端口复用啊，同一个io口通过寄存器配置可以指定其中一种复用。

但是在实际使用中，我可以同时使用SD卡与串口0

如果是串口可以登录，应该是因为没有打开双端显示，意味着屏幕默认没有开启登录，可以开启双端显示，右上角有解决办法

你的板子WIFI天线周围都不能铺铜，你这铺铜都把WIFI天线围住了，WIFI信号辐射不出来，建议将WIFI天线那里铺铜打开一个大缺口。

这个模块只能用陶瓷天线吗，我看的荔枝派的模块好像没有用到天线

千万不要用Windows解压linux源代码。
图省事没用Git下载linux源码压缩包，在Windows上下载了zip后，直接解压然后再共享到ubuntu，结果就是死活编译不通过，文件夹存在头文件报错缺少该文件，这个问题卡了我好几天

在使用官方教程对U-BOOT进行编程时，出现“/tools/binman/binman: 行 1: binman.py：未找到命令”这个错误，尝试完全卸载python2、python3后安装再次安装python2仍然出现这个问题。
安装时出现“选中 'python-is-python2' 而非 'python'”
请问我应该怎么办
