here is the next rewrite for anyone interested, don't worry about the massive errors in the code
its just to show where i am trying to head (if you are a code head..which i am not..who would have guessed hey
)I am SUPER aware that this will run the initialization sequence on power up and immediately start outputting to serial (well i hope it will)
I am going to hook the Arduino up the Logic4 for testing... not the power chair itself,
i want to see the wave forms match or how far they vary from each other and tweak it.
- Code: Select all
#define INHPIN 11 // well its not used for testing this code as yet but will need inhibit at some point
#define JSIGPIN 1 // TX pin
#define LEDPIN 13 // Other output pin to connect to Jazzy line that pulses 255 all the time ?
#define pwrBtn 7 // On/Off button Digital Pin 4, has internal pull up resistor ? or was that pull down ?

unsigned long timer = 0;
int Ypin = A0;
int Xpin = A1;
int YpinValue;
int XpinValue;
int startYvalue = 192;
int startXvalue = 192;
