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...

Resolved! NUCLEO-U575ZI MCU datasheet possible inconsistency? (Alternate Function list)
Hello everybody! Just wanted to clarify. I have still been playing with the TIM1 module. The datasheet for STM32U575ZI states that pin's PB13 alternate function TIM1_CH1N - is the first in the list, thus its number is zero. Yet, the TIM1_CH1N signal ...
How is the flash memory of my STM32L4S5VIT organized?
according to the reference manual. This can be organized in 1 bank of 2mb or in several banks. I have created a default project with the stm32cubeide and I would like to know in which mode the flash memory is configured by default. I can't figure out...
