[ts-7000] simple example module code is here

["Craig Hollabaugh" <>]

7000 users,
I started a new ts7400 development project My project uses
the TS SD card sarge distro on 2.4.26-ts11. It requires some
low-latency processing via internal and externally triggered interrupts. 

I've posted all my simple examples on my embedded Linux trac site,  

http://www.embeddedlinuxinterfacing.com/trac/wiki

Here's the module README.txt url,
http://www.embeddedlinuxinterfacing.com/trac/browser/boards/ts7400/src/modules/README.txt

I've included my notes to
1. hw development setup 
2. native kernel module compile setup
3. svn checkout of module code
4. module compile instructions
5. cross compile modules

Here's a short description of completed modules.

00-template.c
    A simple template file for module development.

01-prochelloworld.c
    Dynamically creates r/w file /proc/helloworld during insmod.
    Stores 8 incoming chars during write and returns them on read.

02-led.c
    Turns board LEDs on during insmod and off during rmmod

03-hwtimerinterruptled.c 
    Blink LED at CPU 1Hz timer via interrupt 42

04-ioremapTShwmodel.c
    Reports the TS model identification

05-hwtimerinterruptgpio.c 
    Toggle DIO_0-7 at CPU 1Hz timer via interrupt 42

06-hwtimer2.c 
    Get 10000 interrupts per second.

07-gpbusinterrupt.c
    GPBUS external interrupt example.

07-gpbusinterruptdio00set.c
    Sets dio00 on insmod, clears dio00 on rmmod

07-gpbusinterruptsoftwareinterrupt.c
    Sets soft interrupt 33
    
08-portbinterrupt.c
    port B interrupt example.

I also have some simple userspace code using mmap. Of interest is a
python 7400 C extension that provides pythonic 7400 object.

I tried to keep things simple as possible. Check it out.

Thanks for the all posts that have got me this far.
Craig
