Re: [Amforth-devel] Amforth 3.9 errors with ATmega128

[Andy K. <an...@ki...>]

Best advice is double check that the serial comms isr stuff rx and tx is commented out and the polled serial stuff is un commented.

After that crack open the data sheet for your device and double check the uart mnemonics for correct uart and that the a b c regisgters are being initialised to something sensible. Ie

8 bits no stop interupts disabled. Make sure mode of uart reg c is definitely async. My original template was set synchronous.

If that does,nt work i think you will probably need to mail out your device and build files so we can see what is in them.

Sorry for my email workstation is belly up and this is from my phone.

Cheers
