jeje ,más que una caja, es una pieza! de hecho, me asombro lo poco que ocupa.....
el atmega128 valdria??? alguien que responda por favor
Sí, pero el USB se tendría que hacer por emulación, porque no tiene..... Aunque ese es una bestia parda, le queda pequeño el PSgroove, seguro que puede emularlo facilmente. Tiene 128k de Flash. y 4k de Ram....
Solo usarias el 10% del chip para esta aplicación.
A ver, lo que he compilado, lo he compilado con linux, usando gcc. Simplemente cojes el repositorio con GIT (primera vez que lo uso) y haces "make". Cuestion de 2 segundos. Mil veces más sencillo que en windows, y 0 problemas o cosas que descargar.
El PSgroove 1.1 NO es compatible con 3.42. NO actualiceis. Es lo mismo que el viejo pero con alguna opción para desarrollo nada más.
El leds.h mio es así:

/** @} */Lo unico importante de aquí, es el puerto, en este caso "D"(PORTD, DDRD), que se corresponden a los pines PDx (PD1, PD2, PD3...). Los defines, (#define LEDS_LED1 (1 << 5)), en ese ejemplo, significa que el led 1 va al PD6.
Y, luego si quereis invertir las salidas (porque son activas a nivel bajo en vez de alto). Pues cambias los "|= " por "&= ~". Es decir, cambias las operaciones binarias que se realizan a los puertos.
, sino es asi casi seguro que no le dare uso..
