I have a lot of different flags in project, I wonder which style definition reads faster by processor .Definition 1 typedef struct{ __IO uint8_t flag1 ; . //other flags }Flag_t ; Definition 2 typedef struct{ ...
I'm looking for an STM32 which features:-Cortex M4 or M7-CAN bus capability -FPU/DSP capability-at least 512kb flash (tough I prefer 1MB or even more)-no BGA (I need to adapt it manually to a breadboard for testing - BGA makes things complicated at t...

I am using stm32f303re nucleo board, I apply a voltage of 3.3 volts directly to the adc2_in2 analog pin of the stm32f303 microcontroller. My adc resolution rate is 12 bits and the value I read is around 3975. this causes me to get wrong results, why ...
I am working with an STM32F429 in a project and I am seeing random BusFaults in random code locations, very infrequently but obviously problematic. I traced one earlier to this instruction ldr r4, [r2, #12].You'll see from the screen capture attached...
HelloTIM1 Capture Compare interrupt of STM32U575 - fails to count pulses of a temperature sensors connected to its channels. We use few temperature sensors of the same kind: LMT01 of TI(https://www.ti.com/lit/ds/symlink/lmt01.pdf?ts=1683467074947&ref...
Hi I am using STM32F407 discovery board. Trying to receive string with USART2 interrupt in this video.Here is my usart2 receive and interrupt codes:uint8_t receiveUart(void) { uint8_t rxData = 0; // IF THERE IS DATA IN THE RECEIVE DATA REGISTER...
