Hydra as a Propeller programmer ... not?
The USB2SER input on Hydra, intended for programming hydra with an external programmer, works also as an output.
You just have to connect the USB2SER pins to the Propeller <EDIT>P31 & P30 through resistors, 330ohm-1Kohm should be fine, according to Mike Green</EDIT>, from left to right 1. /RESET 2. P31 3. P30 4. GND
Hydra has to be powered during programming (resulting in the Hydra being programmed as a side-effect). But it doesn't matter even if two Props are programmed simultaneously. The output signals from Propellers don't interfere with eachother : )
For some reason, I fried a prop once again. With some 500ohm resistors. And power supply @ 3V3 current-limited to under 20mA. I've got no idea what's going on but you shouldn't prolly use this -.-'
