PC-to-R/C interface


Risto K?’s PC to R/C interface let’s you connect to your Futaba radio transmitter. You can use this device to do direct control of your R/C project: prewritten trajectories, user called macros, or direct PC joystick control. He’s built two versions. The original one used multiple D-latches. The second version was an attempt to reduce the number of components. It uses interrupts in the microcontroller software instead of the latches. This would normally cause a lot of jitter, but Risto implemented the interrupts in assembly. The controller can handle up to 16 channels. The LCD displays the last pulse-width and channel.

P.S. I also received a big order from Jameco. Their “100 asst. sockets” doesn’t seem to have a single straight pin in it.
