me gustaria saber si alguien a conseguido acer uso de una TV para usarla como si fuera una lcd , e visto unos proyectos que usan un pic 16f84 e un integrado STV5730A pero solo te venden el producto acabado los codigos e esquemas los tienen en el secreto de los dioses
si alguien fuera tan amavel de poder ayudarme se lo agradeceria ya que seria una buena opcion al uso de lcd ya que aqui en mi pais basicamente no se encuentran a la venta e las lcd que voy conseguindo las saco de aparactos muertos e muchas vezes no consigo info de estas

en esta web acen uso de un pic e el dito stv STV5730a para generar caracteres en una tv e por lo que e entendido seria possivel acer uso de este conjunto de chips para funcionar como si fuera una lcd pero tendre que buscar algo mas de informacion para no estar metiendo la pata , de momento voy a ver si consigo los datashet del stv5730 para poder tener algo mas de informacion que por lo que e leido es un generador osd e de momento es todo lo que se

Hola J1M... me ganaste, cuando fui a pegar el link..... je je
Muy interesante el proyecto Teotekaplan, y encontre tambien al amigo Radon je je je
Voy a seguir mirando...
