3.2.2 特别说明 由于Arduino 下写ESP32程序,这个<WiFi.h>库里没提供 UDP 广播的操作,也就是说,在这种编程环境下,只能跟已知 IP 和端口的远程端进行通信,一开始我的处理办法是,ESP32 向手机小程序端的固定 IP 和端口发消息,但是貌似是微信小程序自己的 bug ,每次在小程序里绑定一个固定端口时,下一次再进入...
3. MA730高速磁编码器,支持SPI & ABZ & SSI & PWM接口 排母边上还有一个3pin(新版改为2pin)的小连接器,是CAN通讯接口,预留后面用的,暂时还没测试,一直用的uart接口。有能力的同学可以测试下,我还没用过CAN。。 使用/测试注意点 1. Type-c usb转串口我只设计了一边有用(因为layout不方便),所以插上去...
因此只需储存EFLAGS,CS,EIP和error code,如果内核栈已经满了,这个时候再次出现中断或者异常,EFLAGS,CS,EIP压不进去了,就会出现不能恢复原来现场的功能,这是一个bug,处理器面对这样的情况时,粗暴地重置自己,设计kernel的时候应该避免这种情况.
Anyways, I will change the pin layout in order to avoid problems, but I would really like to know why GPIO 7 doesn't give me problems (for now at least.)Here is the PINs I should not be using.<!-- ia0 -->Gpios2.png<!-- ia0 -->Statistics: Posted by Midgar — Thu Dec 12...

Then I solder a capacitor (10nf) directly to ground and ADC port pin on Devkit. This reduce the noise so much. I understand that making tests on breadboard mislead tests. Then I made one last test. instead of using Devkit on board USB-UART connector , I connect an external UART-USB ...
# The TDI pin of ESP32 is also a bootstrap pin that selects the voltage the SPI flash # chip runs at. When a hard reset happens (e.g. because someone switches the board off # and on) the ESP32 will use the current TDI value as the bootstrap value because the ...
