STM32F429 DMA2D Bilinear bitmap resize

Posted on May 12, 2015 at 20:23Hello,I wrote a small and very short DMA2D example to resize a bitmap using bilinear interpolation. The resize process is entirely handled using the DMA2D Blender with a low CPU resource usage.The CPU, after a fast ini...

[STM32F4-Discovery] UART4 Problem

Posted on February 24, 2012 at 12:36Hi all, I'm searching to get work my UART4 port on my Discovery. I used the USART HyperTerminal_Interrupt example on stdPerif_example and I adapted to DISCOVERY. I see by some LedOn on the program that UART is wor...

Fastest way to scan single adc channel

Posted on May 12, 2015 at 07:39I am using STM32F205RBT6. System Freq = 120Mhz. APB2 freq = 60Mhz. ADCCLK = 30Mhz.1. I have a input pulse of 300Khz.2. Need to scan single an adc channel on each rising edge of pulse.3. Have to store 21600 samples of 1...
