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...
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...
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 ...
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...
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...
Hello all,I'm new to the STM microcontroller, I want to know the full form of STM. I searched the google but can't get.Thanks and regards,Srikanth M
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-...
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...
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 ...
Hello ST,From datasheet(PM0253), The SHPR1-SHPR3 registers set the priority level, 0 to 255 of the exception handlers that have configurable priority.Also from datasheet,Each PRI_n field is 8 bits wide, but the processor implements only bits[7:M] of ...
