I want to make a streaming from MCU to PC over USB and write as a binary file. Now I have some real problems with USB speed. I tried to measure it andwhile (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if ((dmaFlag != 0))...
In a new CubeMX project it is confusing when there is an interrupt routine or a callback but it is never called . It takes also time to find out who should call who and when. And please document in the function comment who and when that interrupt rou...
im using STM32F030R8T6 (nucleo F030R8 board)i tried to enable SPI2 peripheral clock, but i cant find any line in stm32f0xx_hal_rcc.h to enable spi2 clock,but there is macro for SPI1__HAL_RCC_SPI1_CLK_ENABLE()only few marcos for RCC_APB1ENR present in...
Hi everyone, I'm developing an HMI with STM32F446. it has 800x480 display as well as a stack for communicating the devices with the CAN. Also, this stack must be updated in 4 milliseconds. Now also needing mp3 player and radio. For radio, a IC can be...
I am working with the STM32F760I-EVAL board and caching (SCB_EnableICache() and SCB_EnableDCache() are called) and MPU (MPU_Config() is called) are enabled. I am using DMA with SPI and if I transmit data, HAL_SPI_Transmit_DMA, I need to call SCB_Clea...
I did interfaced STM32l151 with ENC424J600 using SPI , But know i don't understand how to make buff of data to send over ethernet .I did tried some stuff but all says incorrect sequence or frame, sometimes it shows LLC .I am stucked in here please he...
I am trying to figure out the details of how to jump to the internal bootloader on STM32L475. The following code works just fine on the STM32F405, but similar (updating the address obviously, which is actually the same) will not work on the L475.ldr ...
In the M0 I used this code to get the current pointer position U1RxBufferPtrIN = U1RxBufSize - huart2.hdmarx->Instance->CNDTR;but on the H7 this register is not available.How can I find the current Rx pointer position from the Uart DMA controller...
Hello to all.I'm trying to setup the STM32F746-Discovery board for audio transmission.For the audio transmission it is important to use double buffer mode.I'm using the HAL and the stm32746g_discovery_audio.c and wm8994.c filesThe LISR register signa...
We are trying to configure a STM32H743 device to use 8 PDM microphones. According to the manual, this should be possible.In addition, up to 8 microphones can be supported thanks to an embedded PDM interface.The SAI can work in master or slave configu...
