Posted on August 05, 2015 at 19:03I have build and tested the STM32cube Demonstration project using MDK-ARM for the STM32F4 Discovery and it worked fine. So I tried my own very simple project using STM32Cube interface to create the source for a US...
Posted on August 07, 2015 at 15:21We are trying to design a circuit which may need to work at -55 degree. And our current design is with stm32, which is very powerful.Here comes my questions:1. Does stm32f4 series have -55 degree (temperature) versi...
Posted on August 07, 2015 at 16:40Hello again!I'm trying to read from sd card using SDIO. I've succesed to tun it on STM32f103 @72Mhz and after a while I managed to read at about 10Mb/s. But when I ported this files to STM32f407 it hangs somewhere i...
Posted on August 07, 2015 at 03:03 Hello all, I'm trying to communicate with a nokia 5110 LCD. The nokia 5110 has a slave select bit that I am setting using a GPIO pin (because I'm not entirely sure how the NSS bit for SPI works). My probl...
Posted on July 29, 2015 at 14:52Hello, I came across a problem which is about starting a debbuging seession on my System Workbench for stm32 (system Win7 x64). When I'm trying to debug my source code an information appears:Error in final launch sequ...
Posted on August 07, 2015 at 09:58Hello, I'm trying to set my timer3 on ch1 to make an interrupt with some frequency (100Hz). The idea is to switch it on and off by using a USER button situated on my stm32f3 board. I programmed it but it sometimes c...

Posted on August 07, 2015 at 10:41I use STM32F4 Discovery and a USB TTL to serially connect the ARM and the computer I use. I got a serial program and it is Parallax Terminal. The problem is when I download the program to the ARM, the character show...
Posted on August 07, 2015 at 10:22Hi,Is there any USB host example without class-specific driver? I see some examples in the Cube lib, but all are class-specific eg HID/MSC/etcI would like to have a 'direct' comms between a F7-disco and an external ...
