When I used the STM32L412KB as an I2C slave. when there only one slave on the bus, all the function works well. but if there hastwo devices on the bus and continue to access one slave device, the non-addressed I2C slave will damage the SDA bus. I cap...

When I used the Flash Loader Demo to connect with the STM32L412, it could not connect successfully. I checked the AN2606, it said the MCU will reply two ack (0x79) this is different than others. I guess this should be the problem to block the connect...

When I used the Freertos with STM32L433 which the code was generated by CubeMX. In the system, the ADC, I2C, SPI1 used the DMA function. I found that the code will be occasionally into configASSERT(pxQueue ) and being stalled there.but sometimes it ...

When I use the I2C DMA receive mode, how could I know the data has been received? I found if I use the delay to check the data, it seems it could work, but actually, we don't know when the data will be coming. so there should have a mechanism to tell...
