Advantech PCI1751

Hello,

I have got Advantech PCI 1751 card. Current Comedi driver
(adv_pci_dio)  does not use counters available onboard, neiter allow
for command mode.
I guess that it is easier to write a driver for COMEDI than to do it
for system. Since I am new to writing drivers, I would ask some
questions:
1. The PCI 1751 uses 8255 and 8254 chips. My thoughts are that I can
combine existing parts of drivers that use these chips. Which drivers
I should look into for 8254 chip implementation (8255 got its own
driver)?
2. Which driver code can be used as a template, something very close
to PCI1751 functionality (48 digital IO + 3 counters + some interrupts
from few counters and few channels of DIO) - is should not be limited
to insn interface unlike current PCI1751.
3. Are there helpful manuals regarding writing drviers, except
official documentaion?


Cheers, Askar
