ChibiOS Free Embedded RTOS

Just found it, embed it to mode using OR

forgot something , I am using STM32F4

Hi all,

I could not find how to assign port to EXTI channel on 2.6.0, should I do it manually ? On 2.4.3 there is exti member on EXTConfig but it's missing on 2.6.0

Thanks

sorry , thanks to remind me

sorry I can not attach diff file and rare posting into forum I will do it in the future thanks for remind me

This is my work on SPI driver :

yes that's another way, if there is a condition that both device have to work in parallel providing another alternative other than DMA maybe good point, like what I did before.

you are right when the device has alternate DMA Channel in case SPI2 and USART3 both does not have another alternative DMA Channel

Sorry to bother you all, after browsing the forum I realized that SPI2 and USART3 share common DMA channel , after disabling USART3 the SPI2 working normally using DMA.

Thanks

Hi all,

I have experiencing never success using SPI Driver on STM32F4 ( I am using Olimex STM32 E407 ). The SPI it self is working in manual mode and interrupt mode. The driver is working when I patched the driver to use interrupt instead of DMA transfer. It's look like the DMA logic never move ...
