Hello, I'm working with a STM32F407 controller board. Right now, I want to trigger a DMA transfer with one of the internal timers (TIM1). The DMA transfer should read one gpio port and put it into the memory. The timer is configured in PWM mode…
Data transfer from GPIO port to RAM buffer using DMA upon receiving a trigger signal on the timer capture input channel. Our requirement is to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon r…
http://www.efton.sk/STM32/bt.c // Timer-triggered memory-to-memory DMA transfer demonstrator for STM32F4xx (probably good enough for STM32F2xx too) // Note, that we won't use the memory-to-memory mode here, as that would simply run not waiting for th…
一.AXI DMA介绍 本篇博文讲述AXI DMA的一些使用总结,硬件IP子系统搭建与SDK C代码封装参考米联客ZYNQ教程.若想让ZYNQ的PS与PL两部分高速数据传输,需要利用PS的HP(高性能)接口通过AXI_DMA完成数据搬移,这正符合PG021 AXI DMA v7.1 LogiCORE IP Product Guide中介绍的AXI DMA的应用场景:The AXI DMA provides high-speed data movement between system memor…
Ok, so quickly mashing up another example using a different TIM, DMA Stream/Channel for illustration, outputting via GPIOC[0..7] although PC0 is conflicted, it should work as an example. Scoping out PC5 got me my 1 KHz test signal. // STM32F4 DMA GPI…
