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...
I want my system to sit in Stop Mode and then wake up and receive and process a CAN message when one arrives. The code I generated for setting up the system includes: RCC->APB1ENR |= ( 1UL << 25); /* enable clock for CAN -- Note: MCBSTM32 us...
Hi There We need this stock STM32L496VET6. Please help us out,
Hello,I am using STM32F302RCT6 in my custom board. I am trying to setup the SPI dma to directly transfer from external flash to TFT display, so it is the most efficient.Details of implementation:- External flash is connected to SPI-1- TFT display is ...
Its possible to get a flag after standby mode? The signal used to wake up the mcu will remain a lot or time, so I can read it before the waking up, so maybe changing the configurtaion of the pins to normal GPIO?No idea how to solve it and I'm new in ...
I am using STM32G4 which allows 28 standard ID filters and 8 extended ID filters. This is from the Classic Frame Networking example:/* Configure Rx filter */ FDCAN_FilterTypeDef sFilterConfig; sFilterConfig.IdType = FDCAN_STANDARD_ID; sFilter...
