Hello community :)I need help using the EEPROM Memory 24LC1025.I've this address for the 24LC1025 EEPROM ( A0 = 0, A1 = 0 and A2 = 1). And I'm trying to write/read on the data address range 10000h-1FFFFh but I'm not able to, when I try to do anything...
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??
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?
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...
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 ...
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 ...
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...
I tried creating I2C connection between my stm32 board and esp32. I assume it is not working because of my code, due to the wiring being so simple in I2C communication, the pull up resistor is connected externally. Do you guys see any mistake in my c...
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...
Hi,I am facing an issue with my STM32L562E-DK board. Initially, I was able to debug it using STM32CubeIDE. However, after attempting to configure the controller in UART boot mode, I accidentally enabled read protection (DC:LEVEL 1). Since then, I can...
