LCD problem

[mister_e]

Most Bootloader I know, will ignore the config fuses in your code as they're already set in their firmware and don't have the ability to re-program them on the fly. HOWEVER, for many PIC18, you can do it later in your code. Darrel Already post something on that... BUT, using this, you will probably screw up most Bootloader... no free lunch

Bootloader are nice for firmware upgrade, but for development, they have their own limitations.

Thanks for the info.

Thanks guys
Changing to define osc 48 fixed all the problems, LCD serial everything. Now for the question -- Why???
On all the other projects you set the define to the cristal freq. but now you set almost 1.5 times higher.

I am confused can someone PLEASE explain this to me

Well, look in the datasheet, Oscillator section, and check the available configuration fuses setting. Yes they're a bit tricky to understand...

From there, you may discover that you can even have a processor speed of 48MHz using a 4MHz crystal... this is accomplished by the internal set of clock divider and PLL.

As Microchip's bootloader set the Config Fuses for an internal processor speed of 48Mhz, your code must follow it.
