Posted on February 05, 2013 at 08:41I am using stm32f107rct6 with 25Mhz freq for usart communication. i am sending character 'a' from PC but i am receiving some unwanted data like 'FE' and i am receiving the same data no change , so pls let me known...
Posted on February 05, 2013 at 09:27I am using Usart with Dma for external communication STM32F407For transmission we can set the number of bytes to send.But how could I use DMA for receiving, if the number of bytes is not known? I want to get an i...
Posted on September 21, 2011 at 03:27basically i just want to some simple stuff. write in a variable into the flash memory (permanent) and read it , make sure it is the same .as i am newbie to micro-controller, and i couldn't get any simple code or ...
Posted on February 05, 2013 at 10:27 Hello, i am newbe to STM32.and i am using STM32F103C8T6.i have added the USB Lybrary to my code and it was compilled successfully by the gcc compiler(arm-none-eabi).here when i connected my board to PC with US...
Posted on February 05, 2013 at 08:39 Hello Guys, I am trying to play with EXTI of STM32VL but what seems to be the problem in this code why I can't make it work int main(void) { GPIO_InitTypeDef GPIO_InitStructure; EXTI_...
Posted on September 28, 2012 at 13:59Hello all, I hope I'm just doing something wrong. I programm the chip with ST-Link Utility (v2.3.0 - the newest). At read out protection Level0 the programms runs fine. If I set the protection level to ''1'', the...
Posted on February 04, 2013 at 10:17 Hi , I am trying to drive a LED Driver IC with a PWM signal on button press. However , it seems that at the end of a PWM cycle the LED final state is not determinable (maybe on/off). It seem that it...
Posted on February 05, 2013 at 01:35What is the purpose of JP1? It connects to the STLINK MCU, and via two solder-jumpers on the bottom of the board (SB14,15) to PA9,10 of the 'F051 (the USART-1 pins). Can the STLINK enumerate as a CDC endpoint, a...
Posted on February 01, 2013 at 00:39I created some simple code on the STM32F05-Discovery board to write a byte of data repeatedly out USART1. However when I run this code on my target board the USART doesn't send the data. The TXE line goes low an...
Posted on February 04, 2013 at 17:30 Hi all, I trying to use the SPI and I am using uVision Keil. The clock appear with a latency that I can take off by removing while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET); But wh...
