STM32L452 Can't read ADC after WakeUp from deepsleep
In previous time we were using STM32L412RCT6 to do the ADC working, where no problem and work fine, When we have flash memory short, we were decided to migrate to STM32L452RET6 (pin to pin compatible), The issue has occurred, the ADC working fine w...
MotionAC and STM32L073
Good day.I wanted to know why the MotionAC library is not supported on the STM32L073 MCU. And is support planned in the future?
Resolved! How to configure CAN filters to use CAN1 and CAN2 parallelly.
Both CAN buses are transmitting correctly. But when I initialize CAN1 and CAN2 only CAN2 receives messages, when only CAN2 is initialized it receives. same for the CAN1. Here I attached my initializing function. static void MX_CAN1_Init(void) { ...
UART interrupt handler callback is called twice, if bus idle happens at "dma pos"="half dma buffer size"
STM32CubeL4, v1.17.2 in function HAL_UART_IRQHandler() at line 2524.When handling bus ideal situation, there is no condition to prohibit calling the callback if nb_remaining_rx_data = huart->RxXferSize/2. So, both Dma half transfer complete and bus i...
