Famicom Microphone Test

Post by rainwarrior » Wed Jan 16, 2019 4:59 pm

Just a really simple test that reads $4016.d2 once per frame and displays the result onscreen.

I hope it's not rude, but here's mine from a while back:

I don't mind. It's good to have other examples. Tepples' allpads can also display the microphone as a blinking light, if it manages to detect a Famicom system.

As the topic was brought up again I thought I might as well post my Family BASIC version of Rainwarrior's program:

Code: Select all

'MICROPHONE TEST PROGRAM
10 M=PEEK(&H4016) AND &H4
20 IF M=4 THEN PRINT"1";
30 IF M<>4 THEN PRINT"0";
40 GOTO 10
I used Family BASIC quite a lot like this for running arbitrary code before I got a flashcart (before the Everdrive existed).

I posted in this thread my microphone test which records microphone input to WRAM and can play it back, but here's a tweaked version that uses battery-backed SRAM, instead, so that the recordings can be saved. The archive also includes a .sav file with "Hello world" recorded from a Famicom.
