Hi All,I want to use DMA to receive unknown length data. So I config USART_IT_IDLE and DMA_IT_TC and set DMA_BufferSize = 30 bytes. When the length of received data is less than 30 bytes, It works correctly and enters the USART1_IRQHandler(void) func...
I clicked on the function of on the fly startup.It seem can't work in headwind. It can work in downwind.Does anyone have suggestions ?Thanks.
I cannot to set NSS pin in push-pull mode. What is may be wrong?I use SPI1 on stm32F7 as a master only mode with SSOE config bit. My system use SPI clock speed 13,5 MHz. GPIOA#4 is used as NSS pin alternative function 5, push-pull output.This configu...
Hi Experts,I have a project like below. I am trying to send the data but the LEDS are not glowing in sending pattern.I am new to STM32F207 Nucleo board. Could anyone please let me know if I am missing anything.STM32f207 ======> CD4094(Q0) ==========>...
Hello,I want to use the STM32L562QE-DK board to measure the current for my own developed PCBA. There is a connector CN20 that can be used for this purpose as written in the schematic for the board:Output connector to supply and measure external targe...
I am using the STM32H7B3LI-DK dev kit and want to use a simple timer with an interrupt. Using the most basic function, I've added a variable that simply increments within the interrupt. The timer is configured to hit the preloaded value at approx 1ms...

I need to request constant data packets using DMA via SPI on master (STM32H745ZI) from slave(iNemo-M1 with STM32F103REY6 MCU). Despite I have problem using DMA on master side for while I can using blocking receiving.Main problem is with slave side.I...
Hello,I tried to impelement a simple SPI Echo Slave.The Master transmits Data (Example for Nucleo 474RE - Master Full Duplex Interrupt) and the Slave waits for reception using HAL with a datasize of 1 Byte.After the Transfer is completed I am copying...
Hi, tell me, please. On stm32f746, tim3 is configured in encoder mode and works as a master for Timers 2,4,5,1,9. All Slave timers are in external clock mode 1, trigger source in accordance with the table:Tim2 - itr2Tim4 - itr2Tim5 - itr1Tim1- itr2Ti...
