I am working with an STM32F429 in a project and I am seeing random BusFaults, captured against erroneous execution of ldr r4, [r2, #12]. This is one example.
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...
STM32U575 TIM1 Capture Compare interrupt fails to count pulses of a temperature sensor
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...
Resolved! STM32F407 Discovery Board USART2 Read String
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...
Resolved! How to force stop PWM pins in complementary.
Hello,I am working on STM32G474. I want to operate PWM using GPIO. Below code works find for me. but the issue is that after triggering PWM to stop (only output will be stopped and counter remains working), the PWM of timer 1 takes almost 1.2 seconds...
Resolved! STM32G0B0 FLASH memory, page numbers, reference manual error?
I work on STM32G0B0. This picture is correct from reference manual?For BANK1 appears to be correct, but for BANK2, numbering starts from 256 to 383 which I guess id wrong. Shall be 128...255.Asking because also FLAHSH->CR, PNB appears to be wrong too...
device marking format different with datasheet mentioned
Dear Sir,we have a part STM32F205VGT6TR which device marking format not matched to datasheet mentioned, would you check is it has PCN for this change or help to explain which one will be correct, thanks
Resolved! HSI16 frequency user trimming (STM32G0)
The datasheet states two things about HSI16:Accuracy in the full temperature range: -2/+1.5%HSI16 frequency user trimming step: +0.3% - positive steps, -3.8% and -6% - three negative steps.The questions are:With the mentioned calibration step values ...
