The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on January 22, 2014 at 18:50Hi guys,I have SPI1 set up on my STM32F4 Discovery board to communicate with a Wiznet W5500io ethernet board. I'm sending it commands which I expect responses to, but I'm getting no answer. I know the module is wor...
Posted on January 22, 2014 at 09:41i am trying to communicate between stm32100rb discovery value and transceiver cc2500 via spi1. for checking, i wrote a value to the cc2500 to specific register, and then, i read the value of this register, and prin...
Posted on January 21, 2014 at 09:41Hello to all,I am writing application which uses peripheral to memory DMA transfer. When transfers aresmaller than 65535 items written in NDTR register everything is working fine.To be able to support large piece o...
Posted on January 17, 2014 at 11:58 Hi all, I'm tryng to use SPI in half-duplex mode on STM32F303VC microcontroller. The STM32 act as Master. MOSI line is used as data line for input and output. In my setup I have to send an addr...
Posted on January 22, 2014 at 15:20HiI'm porting a software from STM32F101/STM32F103 to STM32F0x family of uC. I need to change the watchdog timeout during runtime. On the F101/F103 this worked. On F0x it seems to fail. For me it looks as if after a...

Posted on January 17, 2014 at 23:28Hey Guys, After I programed vcp for STM32F427 Eval board by following the example of STM32F429Discover board, but when I plug it into the PC, The PC can find it but always get a warning marker on the Device manager...
Posted on May 01, 2013 at 00:02I've made up a board and embedded a STM32F4 on it. I want example assembly code to compile and upload to the chip. I can't find any on the entire internet for a Cortex-M4. Does anyone have a link to a generic GPIO b...
Posted on January 21, 2014 at 18:00Hello,We are developping an application on STM32F401CC mcu and we are not sure that our clock configuration is correct because, when we are setting baud rate of USART1 or USART2 greater than 115200 bps, data exchan...
