Estou fazendo um projeto que usa o display T6963C que o pessoal aqui do forum ja vem me ajudado muito.
Só que estou começando a escrever o programa em assembly e me deparei com os seguinte erro
Estou usando o PIC16f877A
Debug build of project `D:\Desktop\mplab\teste.mcp' started.
Language tool versions: MPASMWIN.exe v5.36, mplink.exe v4.36, mplib.exe v4.36
Preprocessor symbol `__DEBUG' is defined.

Achei q poderia ser os TAB entre os comandos + n tem nada a ver.
O nome das funções que se deve chamar tem um Tamanho maximo ou caracter tipo "_" que não pode ser usado?
Obrigado a todos!
