STM32 MCUs Products

Has anyone had any success generating sinusoidal PWM with DMA, on STM32G474? The same code that I implemented on a STM32F series does not work. Also, the ST example for this board, related to this topic, TIM_DMA, does not run as it has binaries missing.

STM32F7 SAI SPDIF TX channel status / frame count

Dear STM32-SPDIF-TX experts,I'm working with a STM32F767 on a Nucleo-144 board.Creating a sine, sending data at 24bit/192kHz via DMA / SAI 2B, everything fine.Filling the output buffer for SPDIF within the HAL_SAI_TxHalfCpltCallback() & HAL_SAI_TxCpl...

stm32G474 adc ground offset

Hello,I am having an issue with an offset on my ADC measurements. I am using the NUCLEO-G474RE, and I am using pin PA8 as the analogue input.When I measure an analogue pin, the value measured is a bit higher than the actual values. (Actual values mea...

STM32G4 Flash writes at BOR

Hello,We have currently moved on to the STM32G4 series, and we are now looking at a project where data will be occasionally written to flash under control of our own code. Of course, this exposes us to flash memory corruption during unforeseen power ...

HRTIM measurement for continuous frequency measurement <1ns precision

Hello there,I need to measure precisely frequency of square waveform in better than <1 ns resolution. I found that STM32G4x4 have HRTIM with resolution of 184 ps. Can it be used for continuous measurement of frequency ranging 0.5-5 MHz with that high...

stm32G4 interfacing with ESP32 Wroom

I am trying to communicate to ESP32 from STM32G4 using UART communication..the pins that i connected are GPIO16,17,pwr,GND on the esp32 side and tx-rx-3.3v-gnd on the stm side the baud rate is 115200, parity none stop bit 1 and flow control 0 on both...

I2C on STM32G474QE don't works

The I2C4 on the STM32G474QE (128 pins) don't works .There is a delay between the clock signals on the I2C busThe i2C bus was configured for 400Khz.Has anyone an ide why we have this delays between the clock?When we execute the same code on a nucleo-...

DWT not running on STM32L5 with Debugger NOT connected

Hello community,I implemented a microsecond delay on a STM32L5 microprocessor using the "Data watchpoint and trace unit" (DWT). I am initialising the unit and count the DWT->CYCCNT down until my delay has passed.This works totally fine when the Debug...

How does STM32G4 Series FDCAN Tx Queue Addressing work?

The STM32G4 Series Reference manual RM0440 states in section 44.3.3 Message RAM → Tx Queue on page 1965:A Tx Queue Buffer allocates eighteen 32-bit words in the Message RAM. Therefore the start address of the next available (free) Tx Queue Buffer is ...
