I made a driver for 1-Wire communication using UART in Single Wire Half Duplex mode.The communication is started by sending a RESET pulse that should last 480us. I read that to do it using UART I should set it up to 9600 baud, 8N1, then send 0xf0. Lo...
I understand that ADC Linear Calibration is performed during device production and the values stored in the System Memory.However, I have been unable to find any documentation on where the 6 values are stored.Also, are their 6 values per ADC device (...
I would like to know if it is possible to generate a sweep signal (a sine wave with increasing frequency) using DAC with DIMA transfer and simultaneously sample it by ADC and store these ADC values in memory.To generate the sweep signal, I use TIM2 a...
Dear Sir/Madam,I have already implemented the usb host mass storage class project which mainly mounts the usb disk & writes some data to a given file. But this application is not working. Only usb unmout case is executing even though I am inserting ...
The steps that I had done (STM32F429I-DISC1 Board)1. copy and paste the code into syscalls.c2. edit the _write function4. build the project5. edit the debugger setting6. start debug7. enable the SWV ITM Data Console8. enable the port 0 in SWV9. the s...
hi ,Working on USB - Device_Only wake up from Stop mode and entering to stop mode is successful but not wakeup from stop mode .There is no example code for USB wake up from STOP Mode .Entered to stop with following code : HAL_SuspendTick(); HAL_PW...
WHAT IS THE BASIC CODE TO BE USED WITH ANY APPLICATION? THE CODE BELOW COMES FROM THE FACTORY WHEN CREATING A NEW STM32 PROJECT:/* Includes ------------------------------------------------------------------*/ #include "main.h" /* Private includes...
My STM32H747 (Portenta H7), with latest CubeHAL H7 drivers, fails on USB streaming, as USB audio from MCU to host (USB Digital Microphone).It enters in USB FS IRQ handler all the time the branch with the "Incomplete ISO OUT". Nothing comes out to PC....
Not just an idea, something to verify:"PDM microphone via USB or Network"Instead of doing the PDM2PCM conversion (inside MCU) - send the PDM bit stream to a host PC at it is. We can do the PDM to PCM conversion, e.g. with Python scripts, on a host PC...
