Including startup into library
Posted on May 27, 2013 at 16:45Hello,I need to create a library to my BSP so I would be able to use it anywhere.Creating the .a file isnt that hard with CooCox IDE, but the main problem is when I want to use the library in an application, the size o...
DMA to USART1 TX
Posted on May 27, 2013 at 13:17Hi, i'm using smt32F303 discovery board, I send / receive data on USART1 without problem if I use interrupt mode, so I think that hardware is good.I want send a data buffer lenght ~ 8000 bytes using dma mode. Before I ...

digital sampling of GPIO
Posted on May 26, 2013 at 00:35Hi, is it possible to sample GPIOA Bit7-0 into SRAM as byte and to have kind of ''Clk'' nonPWM output on other GPIO , with higher speed than 20MHz on STM32F103 72MHz ? this gives me 10MHz clk output on PC2: Buffer_pt...
Is my GPIO pin configured correctly?
Posted on May 25, 2013 at 00:12 Hello! I'm new to micro controller programming. I have been told to ''poll a pin'' and perform a specific action if this pin ''goes low''. So I wrote this code to ''poll'' a PD10 pin on my board: GPI...
