hello Ingvar,

I>>PS. This problem is usually caused by a capacitor connected directly to a pin or a LED connected without a series res. DS<<

For the gents problem, it doesn't matter whether a capacitor is there or not....

His code is this:

PORTF = %10110000
LCDOut $FE,1,#B8


It will immediately assign portf to B0, and a microsecond later output a value to the LCD on the exact same port. This means, the receiver of the B0 *MUST* be EXTREMELY FAST, and *MUST* be in the Recieve Data mode at almost the very same time your POrtF sends the B0. Or you will lose the data. Capacitor or not...don't matter.

I play with this with my home made Serial communication programs. It times the Transmit and Recieve parts of two chips. The reciever MUST be Slower than the transmitter at the initialization, but faster than the transmitter when receiving the data. The result is a extremely high baudrate transmittion.
