YasPOV Update

April 27th, 2008 in Electronics

I’ve been very busy lately… and some people think they own my time… well that’s another subject.

But finally, I found a day to work on my project YasPOV. These are the updates:

Advances in the firmware
Mounted the final circuit (almost completed now)
Added some items to the design, like an EEPROM to store data

The circuit is based on a 8-bit PIC MCU. I’m using the integrated ICSP capabilities of the MCU to update the firmware, so a few extra components have to be used. I could have used a bootloader, but that would take program space and you wouldn’t be able to debug. I added two NPN transistors as part of the isolation needed to use ICSP.

I will post the final schematic diagram next time, more details and hopefully a working version of the device
