I'm trying to read from an SD card. With the example code (ESP32SD), I have no issues. However, with the main code (esp32-s3-touch-lcd-1.28-demo), the board crashes. I have a file.txt containing the error message. Code: Untitled.cppSelect all ...
禁用JTAG时,只需要悬空该管脚,所以这个管脚不需要加上下拉电阻。 TMS为测试模式选择,提供控制信号输入管脚,控制信号用来控制TAP状态机的跳变。状态机跳变发生在TCK的上升沿,将此管脚接VCC禁用JTAG。建议在外部加4.7的上拉电阻 TCK是测试时钟输入,边界扫描电路的时钟输入脚,如果不需要使用JTAG,则需要拉低,建议在外部...
当ESP32的touchRead(T1)始终返回1时,通常表示触摸传感器处于触发状态(低电平),可能是以下原因导致的: 1.硬件问题 引脚短路:检查T1对应的GPIO引脚(如GPIO4)是否意外接触导电物体(如金属、潮湿环境),或与其他电路短路到地。 电路设计问题:如果外接电路中有下拉电阻或其他元件,可能导致引脚被强制拉低。

The thing that I don't get is, if I use another Service and Characteristic from the same Device from which I can read the Devicename, this works without a problem. I tested another different BLE Device and this I can also control with my code. Does anyone have a clue what I'm doing...
(~ every 23ms) drops one 16 bit slot of transmit data, which is maddening. It's not a dma buffer problem as the drops do not occur on buffer boundaries. I have run the exact same code on the esp32-s3 and same codec without a problem. Moving to 64bclks/wclk seemed to work ...
