Resolved! Fast FLASH programming - mass erase neccesary?
I read in the doc for the G431:"The Flash main memory programming sequence in standard mode is as follows:1. Perform a mass erase. If not, PGSERR is set."So i can not do a single page erase??

SPI DMA is not workng at higher SPI baud rates
Hi,My NUCLEO-H563ZI application uses SPI with DMA. The SPI transactions are not working at clock/2 clock/4 and clock/8 rates, clock being 250 Mhz. Is there any clock frequency restriction when SPI is used with DMA?
STM32H563 DSIZE makes no difference to number of SPI clocks (SPI2)
Folks,I've used SPI many times on STM32F1, F0, F4 devices, but am have a mare with a H563. I have two 74HC165s reading sixteen switches.For hours and hours I couldn't get any clock out when I executed:SPI2->TXDR = 0;Eventually I tried setting the CST...
QUAD SPI External Memory Performance STM32
Hi There - I'm very new to electronic design and need help making a key design decision. Specifically I want to know that the performance will not be a problem when writing to external memory from a stm32 over Quad Spi. I don't want to end up making ...
Resolved! GPIO Demo Program etc
Hello, can someone point me to where there are some demo programs for working with GPIO as individual pins and creating a bus from a number of outputs. I am also looking for a demo program with general s/w based timers, for example, in mbed which is ...
Resolved! Enter low power run mode directly at boot
Hello community, I have this difficult task of powering an STM32G0B1 from a pin that was really not tasked for that (because the connector I have to plug onto provides no supply pin). In short, I can't draw more than 500µA current at any time or I ri...
Resolved! STM32H745 input fast read
Hi, I have problem. I have idea: my STM32H745 must read GPIO state as quickly as possible. FCPU = ~400MHzI wrote the program in assembler for M7LED_ON()ldr r2, [r3, #IDR]ldr r2, [r3, #IDR]... ~650xLED_OFF()...only read, IDR, no write (no record yet)A...
Resolved! STM32f411 crystal
Hi,I am new with stm32F411 mcu, and i have a question. if i want to use RTC features, do i need to add an external 32.768kHz xtal ?Thanks.
STM32WB55RG USART/LPUART unavailable?
Hello, I am trying to set up this is STM to connect it to another microcontroller via LPUART. To my understanding USART1 is unusable since it is connected to J-Link. I have attempted with LPUART setting up both PA3 and PA2 pins as the respective TX a...
How to configure NUCLEO-H755ZI as SPI Slave using CubeMX ?
I am first time using NUCLEO-H755ZI-Q board for our project.Here I am using it as a SPI slave and RaspberryPi4 as a Master SPI Device to transmit/receive data over SPI from MCU shown in attached image1. I have set RaspberryPi4Master SPI CLOCK as 24Mz...
