Yay! I just finished porting the software for my PIC-based audio input switch to the PIC16F630. Earlier this afternoon I got it feature-complete and worked out all the bugs I could find, then in the last half hour or so I got it running on the new chip.<\/p>\n
Tonight I hope to get it working with internal pullups (should be trivial) and then I’ll give the power supply design some thought, along with initial parts selection for the PCB itself.<\/p>\n
Since I haven’t mentioned it here before, it’s:<\/p>\n
– 2-5 input audio selection switch (configurable via jumpers)
\n– Relays for switching audio
\n– Fail-safe design
\n– Switches balanced or unbalanced audio
\n– Next \/ Previous buttons
\n– Mute function
\n– Saves input to ROM so that last state is restored at power-on
\n– MIT-licensed software<\/p>\n
I’ll post more info later. Now it’s time to go home and meet up with Danielle for dinner.<\/p>\n","protected":false},"excerpt":{"rendered":"
