SMARTCARD_ComDMA does this example of STM32U575I-EV support both T = 1 and T = 0.
Hello St community,I wanted to know if STM32U575I-EV example SMARTCARD_ComDMA support both T = 0 and T = 1. Can you please share any documentation regarding this example. As I have seen on AN4800 there is no mention of this example. Please do the nee...
Resolved! How to Perform W25Q16 Fast Read Dual Output ?
Hi,I have been trying to program W25Q16 external flash for Fast Read Dual Out mode. In this mode, basically both the lines MISO and MOSI become input for the host (STM32 in this case) and data can be read at double the speed. My SPI is running at 40M...
USB Mass Storage + SPI Flash W25Q16
Hello,I have a board with STM32F407VET microcontroller, W25Q16 and microSD connector.Writing and reading information from W25Q16 without USB works (using library https://github.com/nimaltd/w25qxx).SD card via USB works.Can you advise what I am doing ...
STM32F400CBT6 - looking for (english) datasheet
Looking for English-language datasheet for STM32F400CBT6 MCU.I've attached Chinese-language datasheet (downloaded from jlcpcb.com/lcsc.com) and a link to a selection guide (https://static.stmcu.com.cn/upload/Selection_Guide.pdf) which tells me that t...
external crystal being perturbed
hi there. I have a stm32 microcontroller which is ran using HSE. the crystal is 11.0592MHz. the code is simple and is about reading some GPIO_Input and send and receive via UART. so far good and simple. this board is actually a relay card. it has 8 r...
stm32f411 halfduplex only returns 1's. happend over night.
I'm working on a project using an stm32f411 and somehow the halfduplex spi only return's once without me touching the code that uses the spi.I'm using platformio (with the 1.27.1 version of stm32cubef4 from github not the pio outdated one) and the pr...
Resolved! STM32U575 is memory remapping required - prior to jump to bootloader from application?
In an earlier project based on STM32F7x, we had to add memory remapping by hand:SYSCFG->MEMRMP = 0x01;There is no equivalent in SYSCFG for STMU575, nor did I find relevant bits under SYSCFG->CFGR1 or CFGR1->CFGR2 or other field as part of SYSCFG.
Is it possible to have two MOSI and two MISO line on 1 SPI bus ?
I'm using the STM32F411RE and I want to communicate with the SPI protocole to an external chip. The version of the chip is basically two single chip on 1 board so the SPI wiring only takes 1 CLK and 1 CS, but is using two MOSI line and two MISO line ...
Resolved! why my hal delay function working weird?
Hi all, This is my first time in stm32 mcu's and since today i struggled to manage to install all needed software to my old win7 pc. Finally at 2am i managed to success. Then after desided to program my bluepill quick before go to sleep. I started wi...
