Reg- voltage control

Hi , I was given a task to control the voltage value during runtime using USBPD in stm32L562CET6 board. Do you guys have any idea to start the process , I have set default value in PDO as 5 volt but the i wanted to change it simultaneously durin...

Connect STM32F769I-Discovery to MATLAB/Simulink for PiL-Simulation

Hi guys,I want to use the STM32F769I-Discovery for a PiL-Simulation in MATLAB/Simulink. As a serial connection I use a USB A to Micro B that is plugged in at the CN15 USB ST-link Port on the microcontroller.. The thing is that when I want to run my m...

LoRa example for STM32WL | un able to read from UART

I am currently working on the LoRaWAN_END_NODE example project for a stm32WL . And I want to receive external data via uart and use the LoRaWan process continually, however I am getting problems. The UART is giving invalid data after the sequencer is...

Resolved! How to ignore bkpt instruction on Cortex M7?

If I understand correctly, the BKPT instruction is "promoted" to hard fault when debugger is not connected.Is it possible to tweak STM32H7 so that BKPT will be silently ignored?-- pa

Resolved! Problem with STM32H750VBT6 controller with external W25Q128 QSPI memory.

Hi Clive.I am running a project on the STM32H750VBT6 controller with external W25Q128 QSPI memory.I need to write data to flash. Your bootloader:https://github.com/cturvey/stm32extldr/blob/main/h7_w25q128/W25Q128_STM32H7XX-CUSTOM27.FLMdidn't work.I d...

HAL_DMA_XferCpltCallback function is not trigger when DMA is transfer the data

HI , am a beginner i am using the follwing code HAL_TIM_PWM_Start_DMA(&htim1, TIM_CHANNEL_1, (uint32_t *)sine_table, 20); HAL_TIMEx_PWMN_Start(&htim1, TIM_CHANNEL_1); // Start the DMA with the 180-degree phase-shifted sine wave table on channel 2 HAL...

Migrate from STM32L433 to STM32F410

I want to port from STM32L433 MCU to STM32F410 MCU for my application. I am using an ECLIPSE IDE and OpenOCD debugging and have custom drivers (not the HAL from stm) for L4 for peripherals and clock. The underlying hardware has changed to F410 and I ...

STM32G4-Peripheral-Cordic_Coprocessor_CORDIC.pdf

Nice presentation, but can someone please revise page 26? Errors: a) 1st result is never read. b) Reading results will not trigger the next calculation. c) Last result is attempt read twice. d) Error is repeated in the subtitles. Repeating fake...

I2S not working on 32-bit data with DMA

Hi,I am using a STM32F407 with the TLV320AIC3204 audio codec. I have verified that the I2S works with a logic analyzer:I am trying to read the data using DMA (I tried both circular and normal).Here is my I2S configuration: I made sure to add the foll...
