Hi.I am using SDMMC1-eMMC(16GB), SDMMC2-SD Card connected on a custom board.Both eMMCs and SD-Cards use FatFS as their file system.Both work fine when used alone.However, if you use f_open or f_write on FatFS on eMMC, you sometimes get an error and t...
hi, i have a problem with my stm32 timer in counter mode, i connected it to a lcd screen, and put a pulse signal in pin PB0, and i wanted to count these pulses and show them on the lcd, but the pulse count is stuck at 0, can you help me with it pleas...
I'm working on some code to wake up from Sleep or Stop mode when a low ADC value happens.I found this post which gets me almost all the way there https://community.st.com/t5/stm32-mcus-products/what-is-the-process-to-use-the-adc-on-stm32f745-to-wake-...
Hello All, I am working on a raw STM32C031C6T6 directly soldered on a breakout board and trying to make a multi channel interrupt based ADC working but the problem i am facing is all the adc's are giving me the same values even after setting the sepa...
I followed the example in article AN4861 where STM explains how to setup RGB565all is working fine but when I switch to RGB888 I get only white and blackI use the image converter LCD-Image-Converter-20161012 tool explained in the article the previe...

Hi,I am using STM32G431 MCU and PB8-BOOT0 pin is used as UART3 RX, with STM32 cube programmer i am able to change option bytes, but for my production, i need single hex file included with option bytes, I tried with below method In .s File added below...
Now, I was only using the stlink part of the card to program another stm32 microcontroller. While running it in debug mode, I cut off the power of the card and it remained in debug mode all the time, in a way that I cannot understand now, and a conne...
I am programming a Nucleo-STM32H563ZI and get a problem while trying to get subseconds value in RTC. Below is the main code: unsigned prev_ssr = 0; char print_buf[32] = { 0 }; unsigned this_ssr; int count; while (1) { this_ssr ...
Hello,Recently we switched to STM32G0B1RCT6 MCU from STM32G071 MCU.We have ported the project to the new MCU. But while doing reprogramming via UART from STM32 systembootloader we are always getting timeout error (Activating KO) in cube programmer.We...
