Project Development
An array of OR gates in the 74LS32 chip was used to insert new control signals from the onboard computer generated in the flow of the vehicle to produce a signal combining, on one hand, the pulses generated by the receiver RF and, on the othe,r the signal generated by the PI Raspberry for each channel and sent as control signals to Arducopter. I made a simple circuit with a pair of input ports 4 bits each corresponding to channels 1 to 4 of the input bus from the arducopter.
* In the image we can see four groups of cables: 2 groups of inputs at the bottom , the group outputs on the upper right and a pair of power lines to 5V in the top left.
