Posted on May 06, 2012 at 19:45 Hi all, I just wanted to share the surprise that I had today when, in order to have the USB CDC example virtualizing USART2 at 115200,8O1 on a STM32F102RB clocked with a 16MHz oscillator I had to configure ...
Posted on March 26, 2012 at 16:03Hi, I not having much success with using the UART (USART1) on my F4Discovery board (STM32F407). I am pretty new to STM32 and Keil (the IDE I am using). Here's my code: &sharpinclude ''stm32f4_discovery.h'' &sharpincl...
Posted on April 30, 2012 at 16:17Hi, I wish to acquire data in continuous mode from Uart, without that the acquisition is completed every packet but after all packets are sent. Thanks for every help. I attach my code. #dma-usart

Posted on March 02, 2012 at 12:34How to send and receive data using RTOS (RL-ARM) with tasks? (Without generating an interruption?) Using this functions below:TO SEND /*---------------------------------------------------------------------------- W...
Posted on January 16, 2012 at 16:56 Hello all, I am using DMA to manage the TX line of one USART (RX stays on standard interrupt). I have no problem with a RS232 tranceiver. But when I use a RS485 tranceiver I got a problemwith the CBUS ...
Posted on January 24, 2012 at 17:15Hi All, I would like to use DMA to service a UART that I am implementing (RX and TX). My project has 2 bi-directional data ports (including the UART) which have different data rates (up to 512kbps). I have to use h...
Posted on January 23, 2012 at 17:49Hi,I am trying to get the usart to work on the olimex stm32-p107 board. I setup the GPIO ports and USART, but cannot seem to send, or receive any data. Has anyone has this problem? or any ideas? Here is my code: R...
Posted on January 08, 2012 at 11:23I�m a newbe at C and try to get some experience on this board. Working on GPIOs are fine.Now I'm trying USART but is not work. Noting come out the TX Pin on USART3 at GPIO PIN D8 and D9. Mabey someone can have a ...
Posted on December 12, 2011 at 17:44Hi,I'd like to connect STM32VLDiscovery to my laptop USB via USART.Everywhere I see that to have RS232 on board it is not sufficient to connect USART pins with DB9 connector. RS232 <-> TTL converter is needed (lik...
