SherpaDoug,
That would actually also be a good idea. I was thinking of using the .3MS pause between pulses but the minimum pulse width is .7MS so your idea would gain an additional .5MS to work in ... |

I started to think along those same lines. I got to thinking I could probably pull each channel during the .3MS pause between each channel thus leaving more processing power for even more things.

It was a different question last week. I did figure out a good way to generate the PPM stream now with a large help from your post.
Now I am concerned with timing and putting it all together witho ... |

I am working on a program on a 18F4550 where I need to read multiple ADC inputs and output a PPM stream that is 22.5MS in length with varying length pulse sequences. See pic below for reference.

You can do that with a code in a timer ISR
Give me a little example and you will be a hero!
I plan to use a 18F4550 so that I can utilize the USB port for some other stuff I need to do a ... |

I have built a Flight Simulator like a helicopter seat that I need to interface with the R/C Transmitters. Right now I have to hack each transmitter and tap in to the pots to access the controls. It ... |

Problem solved. After reviewing the data sheet yet again I noticed that the TTL was able to pick up at around 2.4v but the ST was 0.8 VDD which is about 4.2v which is out of range. By moving the rec ... |

Okay I moved the terminal over to D2 and D3 and it worked like a charm. So for some reason the FORCE_SW just appears not to work right with this particular combination. So maybe I am reading the dat ... |

As an interesting experiment I tried this code.
#use rs232(baud=115200,xmit=PIN_C6,rcv=PIN_C7,stream=HOSTPC,FORCE_SW)
void main()
{
char c;
while(TRUE) & ... |

I tried using the invert option with no success.
I am using the Telit GM862 GPS with the USB EVK V3 from Spark Fun and am directly connecting the pins to the Olimex PIC-P40 breakout board. Here is ... |

I am sure this is s newbie mistake on my part...
The relevant code is as follows.
#use rs232(baud=4800,parity=N,rcv=PIN_D7,bits=8,stream=GPS) // Used to get 4800 NMEA stream from GPS

I would much rather have ccs control these forums than others. And advertising on a forum to try to move everyone over to your forum (or wiki) is just daft.
