I'm looking for advice on connecting 25 PDM microphones to an STM32H7. This seems possible from the RM, taking advantage of 4x SAI peripherals, each supporting up to 8 mics. However, when checking avail User Manual pins on several H7 variants, they ...
I'm using STM32L476 MCU.I config DMA Setting for USART. And I use HAL_UART_Receive_DMA in main.cIf I received data, test_count always increase two.void DMA1_Channel6_IRQHandler(void){ /* USER CODE BEGIN DMA1_Channel6_IRQn 0 */ test_count ++; /* USER...
What is the difference between LPUART and UART?. As far as i read there is no difference to use LPUART and normal one(except power consumption ofc). If I change my UART channel to LPUART, will be any difference? Will be the LP ones DMA usage differ ...
Hi. I want to send an "int" with the HAL_UART_Transmit method. But the strange shapes that I added appear in the picture. Why could it be?
I am developing a project that has M7 processor. I want to use Segger Jlink pin which is JDTI as GPIO.I want to keep it low until I set it. But, while flashing the code to my MCU, JDTI pin becomes high until passing the hal_initialize() function. So ...
Hello!I own an STM32F769I-DISCO board which presents an external connector called "JP1" (a picture of this one is given just below) used to power the microcontroller.So, I would like to know:What is the maximum current consumption by this external co...
Hi I'm working with STM32WB5MMG-dk. The purpose is to develop BLE Gateway. The module has a custom GATT svc with 4 GATT char svc which sends and receive bytes, this data is been provided by MSP430 to STM32WB5 vice versa. So MSP430 acts as master whe...
I am trying to use SPI and DMA in a STM32H7, but it is not worling. The spi handler goes to "HAL_SPI_STATE_BUSY_TX_RX" state as soon as i call the function "HAL_SPI_TransmitReceive_DMA" and it does not do anything, it does not even generate the clock...
