MESA 7I92 programming

If I give you the inputs and outputs, could someone who knows something about this make this xx.bit file for me?


Actually that is why I asked:

"Can you post the pinout of your expansion card? "

As the first reply to this thread...

1 port: IDC26 NORMAL LPT. PORT.
1-2-3-4-5-6-7-8-9 OUT.
10-11-12-13 IN
14 OUT
15 IN
16-17 OUT
18-19-20-21 GND
22-23-24-25 NON PIN
26 +5V

2 PORT: IDC BIDIRECTIONAL LPT. PORT.
1 OUT.
2-3-4-5-6-7-8-9-10-11-12-13. IN.
14 OUT.
15 IN.
16-17 OUT. (17 PIN charge pump Activate card outputs 10-16Khz)
18-19-20-21 GND
22-23-24-25 NON PIN
26 +5V

I need:
5 axis.
1 PWM
1 Encoder A-B-Z
+ Charge pumps 10-16KHz

You would need to specify which pins are:

step0/dir0 step1/dir1 etc encoder a,b,z PWM

1 port: IDC26 NORMAL LPT. PORT.
1 X DIR
2 X STEP
3 Y DIR
4 Y STEP
5 Z DIR
6 Z STEP
7 A DIR
8 A STEP
9 B DIR
14 B STEP
17 PWM


2 PORT: IDC BIDIRECTIONAL LPT. PORT.
11 Encoder A
12 Encoder B
13 Encoder Z
17 Charge Pump 10 KHz. max 16Khz.

1 whatever
2 X DIR
3 X STEP
4 Y DIR
5 Y STEP
6 Z DIR
7 Z STEP
8 A DIR
9 A STEP
14 B DIR
16 B STEP
17 PWM
Would have been much better as 4 axis would be standard pins.

This should be close assuming your pin numbers are DB25 parallel port numbers
