Posted on June 05, 2012 at 21:30Hello, I am new to ST micros and this is my first attempt to design a board based on a 32-bit microcontroller. I've designed a very simplistic circuit with all of the GPIO ready for use for experimenting with breadboa...
Posted on May 24, 2012 at 20:20Very occasionally, my code takes an unexpected exception and ends up in a default handler :)I'd like to write such a handler so that GDB can successfully unwind the stack. For example,default_handler (void) { asm(''ld...
Posted on June 04, 2012 at 05:32Anyone have any example code for USART Interrupts? I've tried finding some example code to work off of.
Posted on June 04, 2012 at 10:55Hi, i'm new in the arm world, and i have bought a smt32f4 (maybe not so good for a kickstart, but i'll survive). i'm compiling the gcc arm eabi toolchain, but i've also seen the Yargarto, is quite used here. For my fi...
Posted on June 05, 2012 at 09:10Hi Andrew, I work on an application with a STM32F207 and a eMMC memory (THGBM4G8D4GBAIE). I have some questions for you. Do you use a file system ? which ? I use the RL-Flash from Keil but it seems to not support sect...
Posted on June 02, 2012 at 01:27I have not received back two units with an STM32F105 that appears to have been erased in the field. The units are sealed, and show now signs of tampering. When received there is no response. When we connect the JTA...
Posted on June 02, 2012 at 18:46Hi All,Is there an easy way to change the priority of TMR1interrupt ? I need to change it so that it has lower priority than USART1, 2 & 3.The M3 TRM, while being quite comprehensive appears (to my simple mind) almost...
Posted on June 04, 2012 at 16:29Hello. I am seeing issues witht he TXE interrupt firing for no reason. Here is my IRQ handler: #define COM3 USART3void USART3_IRQHandler(void) { uint8_t x; // Get Byte from DR in case of Overrun if (...
Posted on May 30, 2012 at 18:19Hi,I am trying to understand the operation of the STM32L-Discovery with the aim of setting up SPI transactions between two STM32L-Discovery devices.When I look at the specs:1) SPI1:SPI1 is defined on PA4, PA5, PA6 and ...
Posted on May 08, 2012 at 23:24Hi All, I'm trying to get Nichelite working with the IAR KickStart Kit for STM32F107VC but so far I'm failing and could do with some help. Has anybody managed to get this going? So far, I've got everything to compile b...
