Posted on May 05, 2015 at 08:48Hi, EDIT: My assumption regarding reentrancy of functions was wrong. The ISRs became active before the buffer structures were initialized. The invalid data caused writes to inaccessible memory. Please disregard the res...
Posted on May 05, 2015 at 01:14Hi,Let’s start with this example :Let’s suppose I work with an STM32F407VGT6 microcontrollers which his System core clock is set at his maximum frequency which is 168MHZ. According to the ARM website the CORTEX-M4 asse...
Posted on May 04, 2015 at 21:36I have a STM32F207VC evaluation board. Most libraries I find are for STM32F1 and F4. Is the F207 obsolete. Is there something newer. Is there a good hardware initialization SW/tool for this CPU. Edit: I use an old Keil...

Posted on May 04, 2015 at 20:43Hi, I'm trying to write a custom initialization for GPIO of F1 and F3/F4 series. I've defined most of the MODE and IO types but stuct at alternate input mode. F1 series puts the pin to input mode while F3/F4 just sets ...
Posted on May 04, 2015 at 13:56Hello,My question is very simple. I'm wandering whether or not we can configure the MOSI/MISO pin as normal GPIO and set them in high impedance while a SPI communication is ongoing (just for clock generation for exampl...
Posted on April 21, 2015 at 02:21Hi, I connected only one qspi flash to the BK2_IOx pins of the STM32F446. Is it possible to use this flash as single-flash mode? Based on the STM32F446 datasheet, there's no QUADSPI_BK1_IO2 for 64 pins package, i...
Posted on May 04, 2015 at 11:45Hello everyone. My target is STM32F091C I want to send something using SPI and after that make an impulse with a bit of my microcontroller. On my scope I see that I send well the data but the impulse is not generate. ...
Posted on April 27, 2015 at 07:42 Guys, I tried to test blinking LED using RTOS and cubemx, but can't make it until now ? what do I miss here ? Please have a look on the main.c .. Thanks for reading and giving a clues...
Posted on January 23, 2013 at 16:16Hi guys,I'm using two channels of ADC1 to convert two different inputs, i'm using the interrupt mode of End Of Conversion. I don't know how to get these values into two different variables.Please take a look at my ...
