Controlling a Serial Dual H Bridge Board with the Stamp

Robomaster

I have a Serial Dual H Bridge Board Kit that I put together and I am using a Basic Stamp-2 to control it. I have one program that works. It uses preset values and delays to control motors and I got one that ramps them up and down in speed.
·
What I am trying to write is one where that I type in the motor the motor control values Motor number, Speed, Direction, and tell it to run .
·
I have attached the code I have been working on. I help in getting it working and I can’t see what’s wrong.

I guess my first question would be what is it doing and not doing? In other words, why do you think it is wrong?

What is happing it is taking the data in but when I tell it to make the motors run it just sit there and motors do not move. I going to attach the manuals for each of the boards. Thank You for your help. ·

Robomaster,

It looks like when you are watching for the DEBUGIN Direction it's waiting for a value of 1 or 2. The ASCII value for the number 1 is 49 and 2 is 50. Try changing the IF... THEN statements with the following.

IF Direction = 49 THEN DIRRA =0
IF Direction = 50 THEN DIRRA = 32

Please let me know if this works.

Just a suggestion, you might want to implement a "valid entry" portion to the program, so you can't get erroneous data.
