Hello,I am working on a project and it would be very helpful if I could find a MCU with integrated 5V ADC. I know you can add a voltage divider for the 3.3V ADC but it won't work in my case for this project. Can anyone recommend me something? Thank y...

Hello,I have never done this so please be patient haha - I need to store around 10 float numbers into the flash memory - I will do this in the last memory sector. The problem that I have is that I can write & read to the flash but if i want to overwr...

Hello,Please be patient, I am quite new to this. So, I would like to implement a virtual EEPROM for my F042k6 mcu, i saw that there is the https://www.st.com/en/embedded-software/x-cube-eeprom.html but it only seems to cover STM32G0 Series, STM32G4 S...

Hello,I am trying to set up CAN communication on my F042K6 using the HAL library. I have followed the stm guide (attached). I got most of the functionality working, however if i try to use the Rx interrupt using "void HAL_CAN_RxFifo0MsgPendingCallbac...

SOSI have tried the other forum suggestions but nothing seems to work so far for me. Basically I am just trying to turn an LED on/off with a set delay: while (1) { /* USER CODE END WHILE */ HAL_GPIO_WritePin(LED1_GPIO_Port, LED1_Pin, 0); HAL_...

of course, i meant voltage divider for the adc inputs.

I assume I need to use a second sector to copy the last known values when the first sector gets filled then move the values back at the beginning of the first sector when it gets cleared, after the values were moved at the beginning of the first sect...

I downloaded it, and I can't compile because of static FLASH_Status EE_Format(void); error: unknown type name 'FLASH_Status'. In the example I cannot find where FLASH_Status is defined

Thank you for this, I will have a look over it

I only need to store some calibrations and some settings for the communication bus. Would not be more than 40bytes - it would only be written to rarely and read each time the device is turned on.
