Hello,
Whether it is possible to create an independent software interrupt like a timer in CSR1010 (other than TimerCreate function)? Also is it possible to give priorities to Hardware PIO change interrupt?
Please help

CSR1010 is a single thread so you can't priorities Hardware PIO change fire interrupt.
But since I know it very fast, I belive you try to do some other fast event that may be support in other CSR1010 Hardware.
What you like to achieve?
You can call my Skype nissim.test
Hi,
Maybe you could try to use the 8051 controller if you want a timer to trigger some IO change. I've never done it, but it seems to me to be possible.
Regarding the priority on IO change interrupt, I've never seem something related to that for CSR1010. Maybe you could do some verification when an interruption is trigged, like waiting for a little time to check if another pin would trigger the interrupt and execute the second interrupt code first. Depends on what you want to do.
Hi,
Can you advise how to use 8051 controller?Is it possible to acccess timers using it ?
I haven't used it yet with CSR, so I can't tell you exactly how to do it, but take a look at the quadrature decoder example, study the file quad_enc_emulator_pio.asm. It is 8051 assembly programming. I think this will help you. Post here afterwards to let us know if you could do it. ;)
