TX problem

[Christopher4187]

Darryl,

I tried what you said but it still works the same. I am so frustrated that this works on the 876 but I can't get it to work on the 688. BTW, at the end of the code it says "goto mainloo" but it should say "goto mainloop." This is just a typo. Anyway, do you have any other ideas?

Thanks,

Chris

What clock speed are you running it at?

Worth adding a
DEFINE OSC with your value of clock you running.

If using internal Clock then if I remember right the 16F688 runs at 8mhz and if you have not Defined a clock speed PBP will default to 4mhz

Regards

Sean.

Download the latest patch to fix this one. http://www.melabs.com/support/patches.htm

Without the patch HSEROUT/HSERIN do not work with this series. Microchip decided to shift the USART config registers (and a few more) into different file register banks.

I guess Microchip just likes to keep 3rd party compiler developers on their toes...:}
