How do you connect more than 12 PDM mics to SAI (H7)
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 ...
Resolved! USART DMA always two times received.
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...
Low Power UART
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?

Using Segger Jlink pins as GPIO's
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 ...
Resolved! About the STM32F769I-DISCO board, what are the maximum current consumption and the power input of the external connector ("JP1")?
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...
Interrupt based LPUART with BLE application.
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...
