[oopic] Re: Help with incoming Serial Communcation from PC to ooPic-R I2c LCD03

Hi Richard,

All the code works and the test message is displayed on the LCD03.

I have tried to implement the sugguested code but it does not seem to
work. What comes up on LCD03 is not what I have transmitted but the
return value to the PC confirms that the char sent is correct. The
LCD03 shows a funny char that isnt even english.

The issue is that the LCD03 display is picking up data that is
transmitted over the I2C/Serial 5pin Programming thing on the ooPic-
r. For example if I have no program running and I transmit data to
the oopic, the LCD03 picks up stuff being transmitted and displays
char based on the ascii code.

Are there any notes that I can read about how the ooPic-r
transmits/receives data and how the buffer works.

It would also be useful to understand how to convert
decimal/hex/char/byte to string.

Thanks so much for your speedy reply.

I have really been suffering to this to work...

Regards,
Angelo
