I was looking at the STM32U575RIT6 and while I was looking for the pinout I realize that there is one for with SMPS and one without for the same footprint, but I'm not sure how to determine if the MCU that I am looking has the SMPS. Is it just if you...
Hi. I am a little bit confused.Why there is so many toolchains for ARM and what are the differences betwen them?Lastly i heard abot Yagarto, and also these is WinARM, arm-gcc, arm-none-eabi-gcc. Are they all the same? which toolchain should i use?I a...
Hello ST,I am trying to interface TDA8026 (NXP) smart card reader with B-U585I-IOT02A (STM32) and not sure how to proceed. Please let me know how this integration can be done.Regards,Rohit
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...
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...
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 ...
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...
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...
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the code that uses the spi.I'm using platformio (with the 1.27.1 version of stm32cubef4 from github not the pio outdated one) and the pr...
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.
