SerialGLCD 128X64

Hello all,

I am trying to use the SerialGLCD and follow the example in the Arduino examples and include my code, but, it doesn’t work. I put a post already for the problem.

I have been adding code to the sketch example and see when I have problems. In my code I am using the timer 1 on CTC mode and a ISR. I notice that when I include the code that initializes the timer 1, the display get erratic a lot of “noise”.

I have 2 questions:

Does any one know if the SerialGLCD library uses the timer 1?

I bought from Sparkfun the SerialGLCD about 2 months ago. Do I need to upgrade the backpack firmware?

Thanks in advance for your help.

Regards,

Manuel
