adding a test area would allow someone to test adding code and images
thanks
like this
yeaa after 6 trys I got it!
now how to insert code?
#include <SoftwareSerial.h>
// if you myserial.print and get garbage tect try this.
// not all LCD's run at the expected speed use this to test yours
#define rxPin 4 // rxPin is immaterial - not used - just make this an unused Arduino pin number
#define txPin 12 // pin 12 is analog pin 0, on a BBB just use a servo cable :), see Reference pinMode
SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);
// mySerial is connected to the TX pin so mySerial.print commands are used
// one could just as well use the software mySerial library to communicate on another pin
int baud=300;// starting point
void setup()
{
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
mySerial.begin(4800); // maybe it is maybe it isn't
delay(1000); // pause to allow LCD EEPROM to program
mySerial.print("?f");
mySerial.print("LCD117");
mySerial.print("it is about");
mySerial.print("time");
delay(1000);
}
void loop()
{
mySerial.begin(baud); // test each speed
delay(4000); // pause to allow LCD EEPROM to program
mySerial.print("?f");
delay(4000);
mySerial.print("baud= ");
mySerial.print(baud);
delay(4000);
mySerial.print("?f");
delay(200);
baud = (baud*2); // increae baud until readable
}
ok that works
