STM32H755BIT DMA2D + FMC + External SRAM Write Issue
I am using the DMA2D to transfer colour data to an external SRAM using the FMC with an 8-bit parallel hardware setup. I can use the following line of code on the CM7 CPU to write to any in-range address (0x68000000 base) with any pointer type (uint8_...
Resolved! I am using stm32f429 discovery and touch controller I want to know how to disable and use it as GPIO.
touch controller //MX_I2C3_Init(); If you do, it will not come out of the interrupt void MemManage_Handler(void). I want to use it as GPIO without using touch controller.

UART Data Getting DMA'd In Wrong Order After First Packet
I have a device that receives six bytes via the UART. There is a known SOF and EOF byte. The first time I get the data, all is well. But subsequent receptions are "corrupted": either the EOF byte is first, or sometimes I get two SOF bytes in a row (a...
SPI example on Nucleo-g474
I'm using a Nucleo-g474REI want to use a timer / DMA to trigger a SPI Rx only transfer to memory.I need to transfer two 9 bit words every trigger, 1 uSecs, and 4096 two word transfersCan anyone point me to an MX cube example?
UART RS485: Driver enable state during IDLE frame generation
Hi everyone,I am using STM32H753 UART along with RS485 transceivers for a half-duplex bus (each node transmits one after the other), and I noticed that although the TE bit is set to generate the IDEL frame before starting any message transmission, it...
