RC Receiver Checker


Hi,

i have built a RC receiver check hardware. The aim is to measure the servo
pulse length and the validity of the Rx pulse length out of a RC receiver. The Rx pulse length
and an error counter for out of range pulses is displayed on a 2*16 LCD STN Display.
The software captures the range and the length of the Rx pulseís every 666 ms. If a servo
pulse length is not in the range of [900 us, 2200us], an error counter is incremented. The error
counter runs up to 65535 (16 bit). Thus a receiver check up to 12 hours is possible.

The hardware is made with a Microchip PIC12F683/PIC16F688 Microcontroller. Software is
written with GCBASIC.

Iím using the receiver checker on new or potentially faulty RC receivers.
Details see attachment.

Best regards
Micha
