STM32F4 TIM1 DMA CCR1

Posted on June 30, 2016 at 21:57I plan to use the STM32F40x TIM1 CH1 (PA8) to produce a varying  PWM  signal. The base frequency is set, say 1 MHz.  I need to use DMA to change the PWM duty cycle on every iteration. I know this can be done by aiming...

How to clear SPI TX Buffer

Posted on January 02, 2012 at 04:06I am using STM32F103 MPU.I set the board as SPI Slave and uses DMA to receive and send data.Most of time Command comes from Master and Slave responses.So I made code to wait for receiving Command from Master. Once ...

DMA to GPIO output pins

Posted on June 28, 2016 at 17:39I wish to transfer a large array of data to 8 output pins that are all on the same port. E.g. a 500 element 8bit array where each bit of each element represents the pin status.So 500 independent transfers to the port ...
