The D.S.C. port issue Concerning the PPM from the JR/Spektrum/Graupner trainer port (also known as the D.S.C. port), I should mention that JR made some rather odd engineering choices. Not only is the PPM there very low level, just over 1V peak-to-peak, but it is also AC coupled through a capacitor....

1. Fixed the current sensor issue (actually just default initialization values) 2. Lowered I2C bus clock rate to 400kHz from 1MHz 3. For those updating to this version, be sure to check that CURROFFSET is set to 0.0 for the SFE current sensor 4. For the SFE current sensor, IMULT should be around 32....

1. Some cosmetic changes to get the screen elements right for NTSC
2. Also fixed a font bug in screen style 2

The DragonOSD+ has a built-in bootloader that allows firmware upgrades to be performed over a normal TTL-serial connection. In order to do this, you will need a serial -to-TTL converter (usually USB) and hook that up to the OSD board correctly. Additionally, you will need to software to upload the f...

The operation of the unit is described in the instruction sheet that came with the unit. As there are quite a number of options, you actually need to read the manual before actually using the unit, to get an idea of how the timer behaves. Basically, you will have to set the timings using the 5-way s...

The shipment from Hong Kong finally arrived today - just under 2-weeks delivery time. The package was small and the box was slightly crushed but the contents look okay.

Serial Port The ICSP programming port doubles as the serial port. Most of the time you won't even need to think about the programming port so just treat it as a serial port. This is a TTL level port so you will need to use a serial-TTL to USB converter to connect it to your PC. Some possible conver...

Current sensor Exercise EXTREME CARE when wiring this up. Follow the instructions here to the letter and the wiring according to the attached photo. Failure to do so will leave you with a blown board almost without exception. Current sensor 002a.JPG The current sensor board actually detects both th...

I2C Peripherals The I2C Peripheral header at the end of the board (lower left side in photo above) can be used to attach various types of sensors to the DragonOSD+. This includes barometric altitude sensors, true air speed sensor, tilt compensated magnetic compass, temperature sensor, IMU, and so o...
