sw4stm32/openocd can no longer edit variables

Weird one this - some time in the last few weeks I can no longer edit the contents of variables in either pop-up view or expression view after I have hit a breakpoint. Memory Browser seems to be OK. This occurs on f3 and f7 MCUs so presumably somethi...

stm32g081b-eval. Code example to get printf / or some other function to print tracing data via ST link COM port for SW4STM32. I am connecting Putty to this COM port.

 I can't find the correct answer from Internet and I don't know do I need to write some code to USART /UART. I have those initialized by code generated by Cube MX.

STM32H7, Atollic strange debugger failure

Debugging on STM32H753-EVAL2 board with Atollic.Sometimes the debugger gets into weird state while target is running.Only full stop (red block) and reset buttons are active. The break button (||) is grayed.Has somebody seen this behavior?I thought it...

Check of the dfu file

Hi,I have built some bootloader for different application and I was wondering if, in some way, I can check if the file dfu is the one related to that application. I tried to change the PID and VID when I create the file with dfu file manager (as show...

How to transmit serially two data simultaneously in MATLAB.

I am using STM32CubeIDE to generate a code and want to transmit two different data(voltage and temperature of battery) serially . I am able to transmit single data at a time means i am able to check voltage or temperature individually but when i am t...

16bit PWM output is jittery using ST Arduino core on STM32F103C8T6

I got my Bluepill STM32F103C8T6 device working in the Arduino IDE with the STM32duino bootloader recently.I was curious about 16bit PWM as opposed to the crude PWM output of standard Arduinos.Using core 'maple' from platform in folder: C:\Users\denta...

what the solution for "No source available for "0x1fffe736"".

Hi, I am trying to generate sine modulated PWM on STM32F401-Disco board using MATLAB. The desired freq of a sine wave is 50Hz and of the carrier wave is 20kHz. But I am not getting 50Hz freq. Please suggest a solution.

I need sine modulated PWM during +ve half cycle of sine wave and zero output during -ve cycle of sine wave. Desired samples of sine are 200. I have attached the MATLAB simulation circuit snapshot. Problem is that I am getting 5Hz freq.

How can I debug Attolic file from STM Studio?

I mean which file I need to put from attolic project to debug it from STM Studio, as .elf , .axf , .out file is not available in attollic generated files.Thanks
