STM32L0 can't flash with FLASHER-STM32

Hello, I am using STM32L021F4 on a custom board and I am attempting to flash firmware using the FLASHER-STM32 software via the internal bootloader and a FT232RL USB/UART serial bridge. I can connect to the MCU and the flash loader says the MCU is rea...

Is there a HAL_ADC_Stop_DMA() alternative to be able to start second transfer using HAL_ADC_Start_DMA() for single conversion?

Using a STM32F413 and ADC HAL drivers.After a successfully completed single conversion initiated by HAL_ADC_Start_DMA() one apparently needs to call HAL_ADC_Stop_DMA() in order for next HAL_ADC_Start_DMA() to actually start a new transfer. There are ...

Resolved! ADC gets stuck after doing a HAL_Delay

In the while loop I have this:HAL_ADC_PollForConversion(&hadc1, 1000); adcValue = HAL_ADC_GetValue(&hadc1);The ADC works okay until I execute this line, which is inside a function:HAL_GPIO_WritePin(GPIOB, GPIO_PIN_7, GPIO_PIN_SET); HAL_Delay(3000); c...

Resolved! Automatically set DBGMCU when debugging starts.

I am debugging my software on STM32L452CCU6 and it is mostly in sleep mode. By default, this disables clocks to the debug port, and the debugger (using STMCube) prints out the message "Target is not responding, retrying...". After a couple of times, ...
