Posted on January 27, 2015 at 14:10I'm new to STM32 board. Working with F103C8, currently I could use TIM2 (24M) as trigger source to start DMA1 to transfer data from GPIOB->IDR(15:0) to RAM. However I found the speed is no more than 8MHz during the...

Posted on January 28, 2015 at 14:48Sorry for my unclear description. No TC interrupt are used, in fact, I'm using a F103 develop board, and I init a 1MHz PWM using TIM3 and output it in PA6. Then I connect PA6 with PB0 using a DuPont line， so the co...

Posted on January 28, 2015 at 13:26 Clive,thanks for your advice, I've modify my test code to enable DMA2, but it doesn't work. I'm using F103C8 whose flash is 64K, I'm not sure whether it has DMA2 module. Below is my test code, I don't know ...

Posted on January 28, 2015 at 13:12 My trigger clock frequency is 24MHz, and I connect PA6 with PB0 on my board to change GPIOB->IDR data in a 1MHz frequency, and monitor GPIOB->IDR data using GPIO_DATA[] array. Below is my test code: ...
