| This branch v0.68d_J16J17 is a copy of v0.68d and has support for switchting J16 and J17 on the FC board: |
| |
| |
| DIFFERENCES: |
| |
| main.c -> line 101: |
| DDRC changed from 0x81 (128+1) to 0x8D (128+8+4+1) to make PC2 and PC3 outputs |
| |
| main.h -> lines 22-25: |
| defined references for PC2 (=LED1) and PC3 (=LED2) |
| |
| fc.c -> line 605-608: |
| added switching behaviour based on POTI2 and POTI3 |
| if POTI2 > 75, output PC2 (J16) will switch to ground |
| if POTI2 <= 75, output PC2 (J16) will remain open collector |
| if POTI3 > 75, output PC3 (J17) will switch to ground |
| if POTI3 <= 75, output PC3 (J17) will remain open collector |
| |
| NOTE on J16/J17 usage: |
| - use an optocoupler to switch external devices like camera's |
| - you can drive a LED straight on J16 or J17 (cathode on J16/J17, anode on +5V), but do not exceed 100mA (otherwise 7805 stabiliser gets too hot). T1 and T2 can handle each max. 500mA but mind the 7805 on the FC |
| - if you want to drive higher currents (for external high power LED's): use an extra FET or a BD transistor (eg: BD138 PNP) via the battery supply (not the +5V from the FC) |

| Good Luck! |
