With collaboration with my friend Rick, I have updated the firmware for my clock and his version as well. My version shows the hours and minutes on 1.8″ displays and the seconds on 0.8″ displays. Rick’s version uses 4″ high digits driven from my display driver boards discussed in a previous blog post<\/a> with alternate displays rotated through 180 degrees so the decimal points act as colons. The new firmware now shows the date, temperature and has a 12 \/24 hour selectable mode along with remote control using commonly available remote sensors and remote controls as pictured. It uses the NEC protocol so virtually any remote control can be used instead. Rick wrote a short program that can read the IR codes from any remote control and dumps them to the serial port so that you can use your own remote control.<\/p>\n
