Vignesh_V · ‎2024-06-04

Hi Friends,

I need Yours Help. I have working on STM32F407VET6 development board and I have to write on simple code like count the values. I want to see the data in SWO (Serial Wire Viewer).But using STM32CUBEIDE to flash the code to my code is not Done . Because, My board is not support to flash the code by using STM32CUBEIDE.So,I have using ST-LINK Utility to flash the code to my board. But SWO is correctly enabled but unfortunately count value is not print in the SWO viewer. So, how to I have the data in SWO Viewer. I have to attach the my software screenshot and source code for your reference that boxed line only I have add to see the count values. Thanks in advance for yours Guidance .

I talking with stm32 based blue pill board like STM32F103C8 (if this type Blue Pill board is Industrial Standard and another question is this blue pill board is manufactured by STmicroelectronics )

https://stm32-base.org/boards/STM32F103C8T6-Blue-Pill.html

Can You have to give any tutorials complete course regarding STM32 in video format for your suggestion?

Example: To access the all peripherals step by step procedure using HAL Drivers.

Yes, the "Discovery" and "Nucleo" are ST's low-cost development boards.

"Nucleo" tends to be just the STM32 (and ST-Link) with no extra bells or whistles (just a LED and button) - so lowest cost;
"Discovery" adds some more extras: in this case, gyroscope, e-compass, digital microphone, audio DAC with integrated class‑D speaker driver - so likely more expensive:

Depends if those "extras" are valuable to you - when they're not, I find they get in the way.

Again, it is 98% certain that any "Blue Pill" will not have a genuine STM32 on it.
