Posted on November 15, 2011 at 12:33I need( from some reason) to get always the same size of bin file.I've tried to create other flash-section and fill it with some value.As last section I added following.. .added : { FILL(0xAB); . = ALIGN(0...
USART1 TX on PA9
Posted on November 12, 2011 at 19:15Hi, I would like to use the USART1 TX on pin PA9 but evan I remap usinf AF (alternate function), the USART1 doesn't transmit on PA9, it is like the USB OTG FS is keeping the pin. I would appreciate it a lot if som...
TIM2_IRQHandler never executes??!!
Posted on November 13, 2011 at 12:40Hello everyone,I have tried to use GPIO PortB, Pin 10 (which i believe can use AF TIM2_Channel 3) to capture PWM signals on my stm32f2. I am using the standard peripheral lib. I am having issues with the TIM2_IRQ...

Posted on November 13, 2011 at 01:49SOLVED: my fault, was writing two bytes less than needed. Hello, PPL! I've already put the quiestion to KEIL forum, but hope, someone here would help me faster. I got:- STM32F103RC (Cortex-M3), - SD-Card on SPI...
General questions on STM32 programming paradigms
Posted on November 12, 2011 at 21:10I could not find any good document on internet about STM32 programming. Unfortunately, STM's own documents do not explain anything more than register functions. I will greatly appreciate if anyone could explain (o...
