Here is a load of software the EZ-CD. For each example I have included, wherever possible, various attachments. These will take the form:
nnnnn-c-src.zip For the C source code
nnnnn-cpp-src.zip. For the C++ source code to use with my C++ tutorial
nnnnn-ATxxx-yy.hex Pre-compiled hex files that you can just upload straight to your controller without any compiler stage
nnnnn - The name of the project
xxx - The AVR processor eg Mega8, Mega168
yy - The processor speed where 01=1MHz, 08=8MHz.
If you are having trouble with the servos then it may that your servos aren't quite centered in the same way as mine. For the C++ source code you change the wat the servos are centered as follows:-
1. Locate the line that creates the servo. e.g. something like: SERVO g_servoLeft( &g_servoLeftOut , true , 1500, 300);
2. The last 2 parameters specify the 'center point' and the amount of 'swing' either side of 'center'. So if you change the last value to zero as follows: SERVO g_servoLeft( &g_servoLeftOut , true , 1500, 0) then the servo will always try to center itself. Change the '1500' value until the servo stops spinning - this parameter is now correct. Now play with the last value to get the maximum amount of swing out of your servo - this should be somewhere in the range 300 to 700.
So here are the examples:-
