TX problem

[sean-h]

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...:}
