Posted on November 10, 2013 at 07:51Is it possible to decode a mpeg4 file in stm32f407 .at least 15 fps & 320x240 pixels.till now  i can decode jpeg pics quite fast . if its possible is there any open source library to do this?i have looked at ffmpe...

Create a position independent executable (firmware image) that can be run from more than 1 location in flash?

Hi,I'm currently developing an application on a STM32F103 MCU that is capable of upgrading its own firmware over CAN. The flash memory is split into 2 partitions and the when the currently active application receives a FW update it copies it into the...

TIM2 exact timebase settings

Dear all,I'm using the STEVAL-PCC009V2 based on a STM32F103RBT6 microcontroller, set to work with an internal clock frequency equal to 72 MHz so CK_INT = 72 MHz (refer to figure 100 of RM0008 Rev. 19, pag. 367/1132).I need to obtain a 10 ms time base...

Write several files "simultaneously" on SD card with freeRTOS fails.

Hello,I built a test app that writes data in files on SD cards in a freeRTOS enviromnent in order to testCube (and cubeMx) librairies 'integration.I wrote a task that write data on one file, then another and so on, the file prefix is the (data) of th...

Feasibility of design concept using extern adc + stm32 gpio + dma

Hi,​I am working on custom design using stm32h743zi with ad9269 16bit 20MSPS ADC. Since I am a newbie for this kind of design and I needed to consider all the analog & digital part at the early stage of design, I just simply connected the adc outputs...
