Posted on May 11, 2015 at 18:37 Good afternoon, I am trying to port an application I wrote for the STM32F407 Discovery board, which makes use of the ADC, DMA and NVIC to the STM32F429 Discovery board. I receive a lot of errors wh...
Posted on May 12, 2015 at 17:21 After searching for a long time I understood that the only reading materials I can get are the reference manual and the ST library comments - not a lot. I imagine this is the main reason I can't get even simple th...
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...
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...
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...
Posted on May 11, 2015 at 17:18I am as the title is trying to suggest attempting to transfer a large packet over an usb endpoint. I am using bulk-transfer and have modified code from the Virtual comport example to neatly package my buffer into 64 by...
