Thanks in advance Dinho -----Mensagem original----- De: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU] Em nome de Thomas McGahee Enviada em: sabado, 26 de janeiro de 2002 20:29 Para: PICLIST@MITVMA.MIT.EDU Assunto: Re: 16F628 USART in ASM Larry, Send me a copy. The next time I update PICUART.ASM I will include the 16F628 stuff as well. I am glad that you found my PICUART.ASM file helpful in getting your 16F628 to work with the UART. Fr.
