Hallo numpang tanya,
Sebenarnya saya ingin membuat semacam telemetri yang bisa transfer data serial lewat jalur audio, sehingga bisa ditumpangkan ke radio rig atau HT.
Saya berpikir apakah bisa 89S51 diprogram menjadi sebuah modem yang mana bisa merubah dari data serial (TTL) menjadi suatu sinyal audio, dan sebaliknya microcontroller satu lagi digunakan untuk merubah kembali menjadi data serial TTL. Apakah ada contoh programnya?
Terimakasih.


Tom Mazouch already built that one.
try to search that....with 89C51 and 89C2051

Also there's AVR and PIC but this mailing list dedicated to MCS-51/52.

I think that we already discuss this before at this mailing list.

Thank's
Jeckson Ben
