He was even kind enough to give me the source code for his microchip.
Well, I had never really made a circuit before, and I had definitely never programmed a microchip before, so I wanted to have a go at re-doing his work to better suit my needs and wants.
For the Tivo I was building I had to build a driver for a standard HD44780 character LCD screen (up to 4x20 characters).
I started from the excellent work by ch424 and all of the contributors to his thread at bit-tech.
Wait 15 seconds, plug the Ti Vo back in, and follow the instructions listed below for your model Ti Vo.
After you have finished the last step of the kickstart process, the Ti Vo will reboot and will perform the appropriate kickstart action.
This is the first, and, as of 2012, current Series4 DVR from Ti Vo.So I completely re-designed his circuit and re-coded the entire project.I definitely used his code and circuit as a starting point, but I reworked every part of it to be my own. The bootloader loads first and in particular situations enters "update mode" allowing a new firmware to be easily installed onto the chip. Bootloader: hex (5.17 KB, updated 2012-11-08) or source (77.71 KB, updated 2012-11-08) Firmware: hex (39.59 KB, updated 2012-11-08) or source (122.71 KB, updated 2012-11-08) Note: The bootloader is optional.This remote will be compatible with all other Ti Vos that use Peanut-shaped remotes.To keep your Ti Vo media device up to date and error-free, Ti Vo releases periodic software updates for the devices.
