Hello,I am utilizing the FDCAN1 CANbus protocol on the STM32H725AGI6 MCU currently. I am trying to determine the execution time for the firmware to execute the lines of code, as the timing can be critical in some applications. So for example, I woul...

Hello,I am trying to optimize a TouchGFX project to see if I can fit it all in a 1 MB internal flash (stm32h725agi6).The design our graphic designers have come up with are requiring the same image, but two different sizes. This leaves two options:1) ...

Hello,I have a .png image that I'm using in the TouchGFX GUI (utilizing the STM32H725AGI6), which I have fully integrated with the display and working.That image is going to dynamically change based on a specific value received from the code (0-100%)...

Hello,I am using BlueNRG-M0A and have a successful implementation working. However, I have a scenario that I'm unsure how to properly program.If I am currently paired to a Bluetooth device (i.e. a phone). The Bluetooth app crashes or the phone goes o...

Hello,I am using the STUSB4710AQ1TR to charge some USB-C devices at the default 45W. I am operating in a mode that's only charging (no data communication). To do this, I used the recommended application schematic provided in the datasheet. My input v...

Hello Tesla,Thank you for the reply!Would you be able to elaborate a little bit further? Can I use any free timer? Would I simply do HAL_TIM_Base_Start() to start the timer, then HAL_TIM_Base_Stop() to stop the timer then check the elapsed time?

Thank you for the reply MM!Doing this test helped clarify it quite well.

Wanted to bump this thread, as I still don't have an answer.

Thank you JTP.I did discover what is was. It was a two layer problem.First off, my FreeRTOS ticks were too frequent that we were only in the FreeRTOS idle task for about 8-9% of the tick and the TouchGFX task was telling the OS that it is it's turn b...
