Posted on May 28, 2012 at 18:28I have been using the Atollic (Lite) for my development. My Atollic Projects work great (doing USB & MMC work). But I have run out of space with the 32K limit. So I moved over recently to the Code Sourcery - or tried. ...
Posted on June 08, 2012 at 17:42Hi,I am having some difficulty receiving SPI data correctly and I am hoping someone could help.I currently have two STM32L-Discovery boards connected via SPI with one acting as master and one as slave. My SPI transmis...
Posted on June 08, 2012 at 11:03Hello, I'm having a strange issue ... when I upgrade from firmware X to firmware Y, the MCU is consumming more amps (board consumption from 50mA to 80mA), and generates more heat (from 42°C to 50°C). I checked a hun...
Posted on April 03, 2012 at 19:57Hi all,I don't see this mentioned anywhere on the forum, but a new version of the STM32 USB library was released recently and it adds the long-awaited support for the STM32F4 family. I've tried it with the STM32F4-Di...
Posted on June 06, 2012 at 18:13Newbie here...I'd like to use one timer as a prescaler for another. Both these timers (combined) will act like a single 48-bit ''uptime'' value, used for timestamping events. The master timer will be driven off APBx.I...
Posted on June 05, 2012 at 16:28Hello All,I have been trying to write into the flash(certain user data), but when i debug it i see the values being written elsewhere in other locations and sometimes in the location i have specified.The function i ha...
Posted on June 04, 2012 at 18:02Hello, I select the ''BOR'' Level 2 with these lines after init: FLASH->OPTKEYR = 0x08192A3B; FLASH->OPTKEYR = 0x4C5D6E7F; while(FLASH->SR & FLASH_SR_BSY); FLASH->OPTCR = 0x0FFFAAE4; FLASH->OPTCR = 0x0FFFAAE6; ...
Posted on June 06, 2012 at 08:48Hi All,I am wondering if there is an internal interlock that prevents the RTC from being updated while the registers (RTC->CNTH and RTC->CNTL) are being read.There is a situation where RTC->CNTH has been read RTC then...
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...
