163/5000
When I use the i2c board with an arduino, I don't solder the jumpers either and then the board will work.
That's why I don't think the problem lies with the board.
I suspect the problem lies with the microcontroller setting.

thanks for your response.
If I change in flow code 48MHZ to 20 MHZ then the LED flashes too fast and the display still does not work.
If I use 48 MHz de led flashes correct.
Indeed I think the error is in entering the "project options"
But I can't find the error.

Hey
Can anyone help?
The LED flashes three times. I can't get the i2C display to work with the 18F4455.
I put the hex file in the microcontroller with a pickit2.

Thanks in advance
