HelloI am using STM32F103C8 and I want to read and write to CAT28F010P Flash chip.This flash chip has parallel buses for data and address. Also there are 3 control lines as CE, OE and WE.So there are 28 lines in total coming out of this chip. I was a...
Hi, I find the search system on the ST website to be lacking. There are a lot of parameters I can't search for/filter by. Is there an ST e-mail / form contact I can use to ask for help? If anyone here can help, I'll try to describe what I am looking ...
Hello,while using this mcu 16bit adc a strange thing happens.the adc signal is test under a sinusoid signal(0.5Hz from a signal generator), and as shown in the figure at certain level adc keeps unchanged, after leaving this level then the signal incr...
Hello there!I've designed a board based on the STM32H743Zit Nucleo board, but unfortunately, I'm facing difficulties with the USB functionality. I'm unsure if it's a matter of configuration or firmware. When I tested USB settings and functionality us...
Hello there! Esteemed ST team member,I hope this message finds you well. I'm reaching out to address an issue I've encountered.I've designed a board based on the STM32H743 Nucleo board, but unfortunately, I'm facing difficulties with the USB function...
Hello, I designed a similar board using STM32H743ZIT6 and STM32H743VIT6. (Rev. V)The board works fine normally.It has been in production for 3 years already. Boards that have already been produced and shipped sometimes become unusable. (since a few m...
@STM32Cube_FW_F4_V1.28.0\Projects\STM324xG_EVAL\Applications\LwIP\LwIP_HTTP_Server_RawI use this Demo，replace phy with Lan8742 sucessfully，then I ping this board ip address sucessfully too,but when I open webpage by browser，the network is down，cannot...
Hi,I am trying to use SPI6 transmission with GPDMA on STM32H7S3L8.While Tx transfer works with simple IT handling, it doesn't work with DMA. No way...To take things simple, I am trying a simple burst transfer (I will leave linked list for later), so ...
