Posted on June 14, 2012 at 10:00Hi all,I'm working on a project with a dumb TFT LCD (320 x 240). I'm trying to display static images (no double buffer). I've been able to display images (in 565 format) that I load on the flash memory and refresh it ...
Posted on September 09, 2013 at 10:05Hi all.I just got the prototype of a new hardware last week and had some trouble in debugging.I use a quite simple setup:- STM32F105R8- External 16MHz Crystal- Outputs to control indication LEDs- SWD for debuggin...
Posted on July 16, 2012 at 18:26I have a large 5x7 pixel font table that I want to store in flash memory instead of RAM memory. I am using Eclipse with the ARM GCC plugin.I am hoping there is something similar to avr/pgmspace.h but obviously for STM...
Posted on September 09, 2013 at 23:32Hi all,I'd like to define a callback function which can be invoked when USB receives something from the host. Where should I implement this in the STM32-USB-FS-Deivce library?I know that in Atmel ASL I can do so...
Posted on October 24, 2012 at 17:13Hello everyone, I have been experiencing an issue with USB recently on which I wouls need some tips. I have an Olimex H103 board running a STM32F103 chip. I have been running my code on it and usb works fine. I hav...

Posted on September 06, 2013 at 20:32Hi, first of all, I'm writing a new thread because I couldnt reply to [DEAD LINK /public/STe2ecommunities/mcu/Lists/STM32LDiscovery/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/STM32LDiscovery/STM32L%2...
Posted on September 08, 2013 at 06:54 My question is probably simple. Can I configure external interrupts triggered by PA10, PA11, PA12 and PA13? Studing the EXTI example I understood something like this: PA0 is connected to EXTI_L...
Posted on September 06, 2013 at 13:49I am using 2 ADC inputs on an STM32F103. Vref is 2.500V, from a voltage reference. One input is multiplexed via relays from a variety of external analogue signals and works well. The other is used to monitor th...
Posted on September 06, 2013 at 21:23Since the STM32F407 has 2 USB ports, OTG_FS and OTG_HS, can both ports run at the same time? I want OTG_FS to operate as a host and OTG_HS to operate as a device at the same time.All of the sample code from ST op...
