(Cubelde) I want to send uint8_t array and float variable with hal_uart_transmit. How can I do
I've tried things but I don't understand the exact logic l.

hello all, for an internship I work on modulation / unmodulation BPSK.For the modulation I used a DDS drive by a stm32.But I want to know if it's possible to make the unmodulation only with STM32. I know we can measure the freq with it but can it do ...
Hi FolksI'm running a design where i have a sort "Expansions" board where all the Analog inputs and RS485 / UARTS port are located.This board is running a STM32F107 mcu.Then i have another board running a STM32F429NIH6 MCU, where we handle LCDs, ETH...
Hello,this is my functionvoid process_dds_ext_demod(uint16_t *inbufPtr1, uint16_t *inbufPtr2, float *in_phase_val, float *quadrature_val){ /*transfer DMA buffers to local Buffers-------------------*/ //transform values from int to float float ADC1_Bu...
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...
