Posted on June 10, 2014 at 16:54Hi all, I have a project where I need to deal with 4-to-8 bit and 8-to-4 bit conversion and so I have a questions: 1. I know that I can do DMA to/from GPIO but what is maximum speed of that operation. Can I go up to 2...

Posted on November 18, 2013 at 08:25 I am fighting with this from couple of days. My uC is STM32F407VG. I want to sample 3 triggered channels. For now I am triggering ADC using software but finaly I will use timer and dma, but for now I can'...

Posted on October 03, 2013 at 09:50Can I configure two usart's to use one DMA? In datasheet there is table called ''DMAx request mapping'' and for stm32f40/1/2/3 eg. UART4 uses channel 4 for RX and TX DMA trigger on stream 2 and 4. Can I configure s...
