Posted on January 09, 2013 at 10:56Good morning, i'm using a STM32F0discovery board, i'm developing an application that read and write informations on UART2 port, i'm using only TX and RX pins (PA2 and PA3).Well, at this time my application ask me w...
Posted on January 08, 2013 at 20:31I have a question. I need to connect 2 to 6 STM32s together. I have motors I need to collectively control with a human machine interface. Each motor will be controlled by one STM32. The HMI also needs a STM32. ...

Posted on December 19, 2012 at 12:47 Hello pals i am new to the stm32 programming, i am trying to configure usart via irq handler, can someone help? #include <stm32l1xx.h> #include ''stm32l1xx_usart.h'' #include ''STM32_Init.h'' void ...
Posted on December 14, 2012 at 08:30HEllo ALL, I am using stm32f2 and i have programmed USART which is interfaced to GPS. The problem i m facing is, When USARt is enabled, i always get the my RXNE interrupt set, since GPS sends data continuosly and ...
Posted on December 10, 2012 at 03:33 I have been trying to get UART working for the last couple of days with no luck. I have tested an UART example code and it worked. So clearly there is something I am missing. I would really appreciate any hin...
Posted on December 10, 2012 at 01:57The manual says that the STM32 supports only 8 and 9 word length for UART.But I need 7 data bits.How can I configure the 7 data bits? #7-databits-uart-usart
Posted on December 08, 2012 at 04:37The device I am trying to connect to via serial interface requires constant clock ticking. I have enabled USART clock with USART_ClockInitTypeDef USART_ClockInitStructure; USART_ClockStructInit(&USART_Clo...
