I2C does not work on pins (36,37) of ESP32S3 R8 Posted: Mon Oct 16, 2023 6:47 pm by msh911 Hi I am reading a gps module data. I have a code that runs properly using pins (7,8) for I2c communication on ESP32S3 R8 on my prototype board. However, on the designed pcb, the...

If you short the pins while communicating, the chip almost always crashes with interrupt watchdog timeout. There is a line in i2c_master.c:566 where there is a while(i2c_ll_is_bus_busy(hal->dev)){} running in an ISR context. This will trigger the interrupt watchdog if the device ...

RK3288烧录的是官方固件,开机log里,kernel启动之前显示 I2C Send Start Bit Timeout。kernel启动后显示 i2c is not in idle 请问是哪儿有问题啊。DDR Version 1.00 ... RK3288烧写固件后没法启动,一直显示I2C有问题 ,Firefly开源社区
the Waveshare RP2040-LCD-0.99-B rounded display but they would offer no expansion pins or GPIO through pads or 4-pin connectors, while the ESP32-S3 display features a terminal block with additional interfaces like RS485 pr CAN Bus that should make wiring more convenient and versatile for the...
