Posted on September 26, 2014 at 09:18I want to design a PCB that uses the embedded LCD-TFT controller of the STM32F4x9. Are there any guidelines available for the PCB design for the traces from the MCU to the LCD-TFT connector? Is a specific trace i...
Posted on September 22, 2014 at 12:23Hi all.I have a project that need to connect a NFC reader/writter to STM32F103. The MCU module is designed myself so I will not mention about some modules like Arduino,...As far as I know, PN532 is a good choice ...
Posted on September 25, 2014 at 21:49Where can I find the instruction set for the STM32F401 part? I know ... it's hardly necessary to see at all these days but I'd like to have it as a reference anyway. TIAMike #arm #joseph-yiu #assembly-instruct...
Posted on September 25, 2014 at 13:21 Hello I have a Nucleo-F103RB board. I am using the I2C1. I want conncect to PB5 to a external interrupt. My idea is conect PB5 to the int out line of the one acelerometer ''KXTF9-4100...
Posted on September 22, 2014 at 14:38Hi all! I am running a 3 MCU solution were all MCU:s are communicating 21MHz full duplex SPI to eachother. As: MCU1 SPI3 Master <-> MCU2 SPI3 Slave MCU1 SPI2 Master <-> MCU3 SPI2 Slave MCU2 SPI2 Master <-> MCU3 S...
Posted on September 22, 2014 at 17:44Hi,I was working with Keil+ulinkpro on a custom board using an stm32f217 and everything was fine. I start working on some automated script for inital setup for our product using openocd. Somehow, it rendered th...

Posted on June 01, 2012 at 16:59 I am trying to erase and program a 16KB sector (sector 2) in the STM32F405 (rev A)on the ST3240G eval board. The problem is that two error flags (PGSERR and PGPERR)are set and cannot be cleared. Soon afte...
Posted on July 31, 2012 at 23:39I need to transmit 16 bytes from a buffer to SPI1 using DMA without interrupt. Someone would show me the code to configure the SPI and DMA to do so?Ari.
Posted on August 07, 2012 at 23:40HelloI implementing something like own watchdog, but I can't reset STM32 in SysTick interrupt. It just stop SysTick interrupts but nothing more.I tried to disable interrupts before, but it is same with:__disable_irq...
