Is there any programmable driver except for NANJG/7135 ? [With ATtiny or etc.]

Tivo’s East-092 Zilog MCU driven driver

Here is his Nanjg style with the Zilog MCU as well

These are actually very intriguing drivers, and well thought out too

The zilog programmer can get expensive though, and coding is different from the Amtel ATtiny MCU’s

Of course there is the multi-mode MELD driver by tterev3

heck check out the OSHPark projects page…plenty of different drivers, for the most part the ATtiny is the defacto MCU because it appears the easiest to deal with
