I'm trying to play a sound file with raw PCM data using the DAC:uint8_t buffer[16384]; // 4-aligned uint8_t *bufptr[2] = {buffer, buffer + sizeof(buffer) / 2}; int curr_buffer = 0; volatile int audio_dma_half_complete = 0; f_read(fh, buffer, sizeo...
I have SPI2 set up to access external flash - and it works well without DMA.Setting up SPI2 to access flash with DMA, a read correctly fills the buffer provided - but my callback functions (overriding their __WEAK counterparts) aren't called (HAL_SPI...
Hi, I'm using stm32f401RE.I set UART functions by using CubeMX and I'm trying to get data from UART and distinguish them.Here is the code.uint8_t RxBuffer[8]; HAL_UART_Receive_IT(&huart2, (uint8_t*)RxBuffer,sizeof(RxBuffer)); // Writed in while loop...
Dear Member, How much is the minimum stack for FATFs, 10Kbytes is good enough? or more ?thanks
With the current "typedef struct" for peripheral handles, callback code that deals with multiple instances of a peripheral, such as uarts, CANs, etc., often has to do a lookup a lookup on the handle passed to it by the peripheral callback. If the ha...
Receiving TCP stream that spans two packets fails after several seconds. Pings still work. The STM32F7 replies to the receive stream with duplicate ACK'sThe TCP stream does not recover.Ethernet Receive Logic Review using STM32Cube_FW_H7_V1.3.2/Proj...
On a STM32F042K6 (using the latest CubeMX software and FW_F0 V1.9.0), we have code that goes into "Stop" mode to achieve low power. A pin connected to PA0 (EXTI0) wakes us up.This all works great. Except that we can get the system into a state wher...
Hello everyonei using Timer 1 and set PWM on CH1 and CH2N CH1 is work fine but CH2N not working (i checked pin work fine on nromal GPIO)my code only have two line :HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_2);any...
Hello,i have a strange problem when i try to work with a FatFS on SD cards with SDIO.MCU is a STM32F439ZI, SDIO 4 wire for SD cards, FatFS for SD cards (used CubeMX 5.1.0 to create the base code, working with Atollic TrueSTUDIO 9.0.1)I have working c...
