Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.



RCST. How does it work?


Recommended Posts

I found this forum while doing a search for a servo tester.

The RCST project is very interesting in that it reads a potentiometer from a digital i/o. Is it possible to learn more about this program? How does it generate the pulses? Is it possible to have the source code to learn more? I am new to pic programming.

Thanks.

The RCST source code is not available. However, servo pulse generation is a popular application for microcontrollers. You should have no problem finding a variety of published projects that will help you out.

Regarding reading a Pot from a digital input, all you do is read the time it takes to charge the capacitor to a logic high threshold. It's the same method used by the POT instruction found on the Parallax Basic Stamp board.

Thank you for your reply. I will do a research on servo pulse generation.

Regarding reading a pot, do you mean that first you set the input to a logic high, and then check its value within a loop?

I didn't know that one you could actually set a logic input to a desired value.
