何必胡搅蛮缠,从头到尾,这个帖子讨论的就是“公开资料” 而不是 “技术支持”, 这几个字很难区分吗?

卖产品,是要直接跟客户对接的,客户对你有要求十分正常
我就想问,个人用户是直接找芯片厂家买的芯片吗?

公开一些SDK 、参考手册、 各种应用手册,跟小白提问有什么关系?
整的好像有面向个人技术支持渠道一样

才10个名额,
除了10个开发板以外,建议可以免费送芯片,然后名额多一点

查了一下淘宝价格,现在单片价格还是太高了,没什么动力搞几片玩玩


建议看看D133CBS

D133CBS 看起来性价比也一般。

还是说说我比较感兴趣的D211系列吧,价格大概是v3s的两倍,还是跑600M 的c906,本来c906 就比不上a7。
不过接口还是比较多的,这个是个加分项

那个uhci ohci xhci之类的驱动选了吗

是的,之前只勾了xhci uhci 死活识别不了,后来加上 ohci 才行

#9 Re: 全志 SOC » v3s usb无法识别到ch341/ch342 » 2023-09-18 21:04:41

好吧,原来这俩设备是usb1.1 , 需要在kernel和设备树里打开ohci

插入ch341 这种usb转串口,死活没反应,lsusb也看不到设备。但是插入usb网卡就可以正常识别。

我板子上还画了个ch342,以为是画得有问题,但是直接用usb口插了ch341也是没反应,实在不知道问题出在哪儿了,请大家看看


用的主线5.19的内核,USB相关的config设置如下:

CONFIG_USB=y
CONFIG_USB_ANNOUNCE_NEW_DEVICES=y
CONFIG_USB_OTG=y
CONFIG_USB_EHCI_HCD=y
# CONFIG_USB_EHCI_TT_NEWSCHED is not set
CONFIG_USB_EHCI_HCD_PLATFORM=y
CONFIG_USB_ACM=y
CONFIG_USB_MUSB_HDRC=y
CONFIG_USB_MUSB_HOST=y
CONFIG_USB_MUSB_SUNXI=y
CONFIG_USB_SERIAL=y
CONFIG_USB_SERIAL_GENERIC=y
CONFIG_USB_SERIAL_CH341=y
CONFIG_NOP_USB_XCEIV=y
CONFIG_USB_GADGET=y
CONFIG_USB_ROLE_SWITCH=y

设备树里otg设置成的是host, ID引脚在板子上没有用到,也没有连接(typeC接口)

&usb_otg {
	dr_mode = "host";
	status = "okay";
};

&usbphy {
	usb0_id_det = <&pio 5 6 GPIO_ACTIVE_HIGH>;
	status = "okay";
};

#11 Re: 全志 SOC » T507,T507-H有区别吗? » 2023-03-05 22:56:37

哇酷小二 说:

应该没有区别,

据我所知,HDMI版权方要求在非H系列,但是带HDMI功能的芯片,得在型号后面同一加 -H

比如 D1 改成 D1-H 就是这个原因

还有这种要求,hdmi版权方是谁呢

v3s的h264编解码延迟怎么样?

视频效果还可以吧?

是的,效果很好

回复: 0

小弟对视频编解码和显示这块不太了解,买了块orangepi3 LTS,用的是全志的H6

看了下手册,他说目前在5.16的内核上,mali GPU的支持是OK的,但是视频编解码 不OK,
我有点疑惑,视频编解码不是用GPU加速的吗?为什么一个OK一个不OK呢?

或者说GPU OK,是指哪一方是好的呢?

computman 说:

@ncer
硬件问题确认方法:
1. 万用表测量供电是否正常
2.wifi都有时钟的,需要看看时钟是否正常,和软件配置的时钟是否一致
3. 如果要测试连接,可以看看接口上是否有对应的波形。

谢谢,学习了

wycc 说:

是使用 SDIO 嗎? 要怎麼連接呢? 我想在自己的 V3S 平台上試試看。

接线可以参考这里,接到v3s的mmc1上
https://github.com/Ncerzzk/esp-hosted/blob/cross_compile/docs/Linux_based_host/SDIO_setup.md

#20 Re: 全志 SOC » 我想知道文件sun8i-v3s-licheepi-zero-dock.dtb你在哪里得到它 » 2022-07-25 22:42:39

编译设备树即可得到dtb文件:make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs

至于sun8i-v3s-licheepi-zero-dock.dts, 是由licheepi的生产者sipeed维护的

可参考:https://whycan.com/t_561.html

#21 Re: 全志 SOC » v3s使用XR819 wifi芯片求助 » 2022-07-16 21:49:57

仔细检查了一下,发现使用主板使用该模块的原理图符号画错了,导致信号线连接错误了,令人汗颜,只能另外打板测试了

#22 Re: 全志 SOC » v3s使用XR819 wifi芯片求助 » 2022-07-15 22:45:30

哇酷小二 说:

首先确认硬件有没有问题?

如果硬件没问题, 看下 dts 里面 该 sdc 有没有启用?

硬件问题不太好确认是不是OK的,因为感觉外围电路比较简单就直接打板了,手头也没有成品的xr819模块来对比,头疼
原理图:

https://github.com/AutopilotPi/XR819_Module/blob/master/XR819.pdf

dts是启用的,启动日志下看到有

可能需要固件, 看下日志.

固件放到/lib/firmware 下面了,用的是这几个文件: https://github.com/armbian/firmware/tree/master/xr819

日志在这里,请晕哥帮忙看看

#24 全志 SOC » v3s使用XR819 wifi芯片求助 » 2022-07-15 21:39:24

板子上使用xr819,v3s 与 xr819的连接关系为:

PE23 - reset
PE24 - WIRQ

驱动使用 https://github.com/fifteenhex/xradio ,也成功编好了,到v3s insmod xr819.ko
然后在ifconfig -a 里并没有新增加一个网卡

目前有点束手无策,不知道从哪里下手

请教一下没有电流传感器的力矩控制大概是如何实现的?

电流传感器的加入是使力矩控制闭环,没有就是开环力矩,这时速度环的输出直接确定力矩的大小。

这不能叫做“控制”力矩吧

你i2c连设备了吗?设备上的scl sda上拉了吗?
如果设备和zero都没上拉,那肯定不能正常工作。

感谢分享。看起来像是把marlin固件中GCode-> 步进脉冲 的部分用来python来写,单片机只是作为PWM的实时产生工具,根据楼上分享的路径,看起来也可以直接用PWM输出芯片直驱步进电机。

做了一些更新,考虑到要用在飞机上,使用sd卡很不安全,目前的版本换成了SD NAND。

已经成功了,就是这延时稍微有点高,感觉有点卡卡的:

V3s侧会有一些报错输出,暂不知如何解决:

dtsayhi 说:

老哥姿态检测之类的实时性应该没问题吧。准备用WIFI还是2.4G

不跑其他程序的话,实时性应该还可以。

遥控打算使用ELRS,目前在航模界大量应用了,基本就是esp32+LORA芯片(2.4G 或者 900M),与飞控通过串口通信。

hotkey 说:

选这个芯片是为了方便装摄像头么?

其实主要是看上了:
- 芯片方便手焊
- 自带内存,不需要走DDR线(我也没走过高速电路)
- arm A7 核,性能还可以接受

实际用上之后,最主要的问题在于PWM通道不够,最近又发现了新的好东西T113, 好像有8路PWM输出,对于飞控来说很方便。

至于摄像头,确实有想过把飞控+图传集成在一起,但是怕有点带不动,不是主要目的,可能等基本功能OK之后会测试看看

工程地址在JLC,第二次用LC EDA了,说实话,找封装比较方便,但是很多点实在用的比较难受
https://oshwhub.com/Nccer/my_v3s_copy

板载ICM20600/spl06/QMC5883L, 还有一片高云的FPGA(用来输出PWM)

这是第二版了,第一板就是下图那个比较大的方方正正的板子,那是第一次用LC EDA,画完回来发现忘记画LED了,上电一个灯都亮着实有点慌
再加上上面没有磁力计,于是就琢磨着画了第二版,把一些电机驱动电路/锂电池充电电路给去了(原来是希望能直接控制一个空心杯四轴的),
画得更小

焊得有点叙利亚成色了,因为这个芯片是吹下来的,希望能白嫖晕个的两片V3s,下次焊新芯片
