I place a break point in the callback HAL_ADC_ConvCpltCallback() and the first time it is entered EOC, EOS, OVR are all set. So I have already missed reading a conversion. How are mulitple values read using interrupts. After reading through the doc...

I am using STM32CubeIDE on linux Also an aside the debugger is having problems finding source files even if I give it the correct {project}/Core/Src directory. When I give it the actual file it is happy. Thank you and have a productive day : )

Hello,I am using nucleo-64 board and CubeIDE in linux ubuntu.Everything is working fine except I can not see any of my serial output from the application. St-link is connected to usart2. I thought they could be used at the same time. Do i need to use...

Hello,My O.S. is Linux Lite (ubuntu).I am getting "No such port: '/dev/ttyACM0' msg when I try to open the internal serial monitor in the IDE. I also tried /ttyACM0, etc.. When I use the Aruduino ide I can access the port successfully.ThanksTop

I am using the ADC on an stmf030 nucleo boardI am having trouble with controlling the interrupts.I am scanning two channels, have eoc & eos enabled to cause an interruptI am using software trigger.My main issue is: The ADC ISR keeps firing away with...

You have to put the code you want to add in between these comments. Then CubeMX will not over write what you havein there. Just an example/* USER CODE END SysTick_IRQn 0 */ code here will not be overwritten /* USER CODE BEGIN SysTick_IRQn 1 */

Try a google search for example stm32 nrf24l01 github

Jan answer works. Also he is correct about using dma. The ADC is fast so getting multiple channels is better done with DMA. I reserved a 1000 memory locations and also used a counter in the interrupt routine. When the count reached 1000 I hit a ...

I am using STM32f030R8 nucleo board. Pardon for the omitted information.As you say the break point stopped the program but the adc had already started on the next conversion.Everything worked when I increased sample time greater than 41 cycles.As yo...

I thought the debugger was going back and forth between debug window and main.c because it couldn't find some source files but that is not what is happening.

Using ADC in interrupt mode, using callback HAL_ADC_ConvCpltCallback() to read values from two channels. But I am getting OVR error.

When stepping through code the debug window gets the focus momentarily after each step, and then back to the main.c window. I don't remember this happening. Anyway to turn this off ?

While in debugging via st-link i can not connect a terminal in order to to see serial output.

Can not open serial port in IDE

I am having trouble controlling ADC interrupt routine
