Fixed decimal for Nav or Com Radio?
Hello,
I am using the opencockpit I/O card , opencockpit diplay card along with their 7 segment circuit board (holds five "7-segment displays") to try to get a nav or Com radio to work.In the early stages, every thing seems to be working correctly except for the fixed decimal place........... no decimal is showing?
I have posted on the Opencockpits forums, but have not got any answers yet.Does anybody here have any experience with this type of set up?
1. Can I use SIOC to get the decimal to work?
2. If not, do I need to short circuit the pin of the decimal some how ( without using a resistor?
3. Or , Do I need another 5 volt source ( and resistor) to feed power to the decimal.
Thanks,
Polmer
