multi device SPI bus on RTOS - zjeriet - Jul 10 9:44:31 2009
Hello all,
Has any of you guys has some experience with incorporating a multi device SPI bus into a RTOS? All devices can throw IRQ's to the processor. I've been looking on the net to find some info but I'm not able to...
To access the SPI devices I use a semaphore on the SPI bus, but in the ISR's I can't use that semaphore (due to the RTOS).
Help would be greatly appreciated if you can point me in the right direction.
Greets,
