 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |
Forum Index : Microcontroller and PC projects : Cfunction request: Additional console RX

I'm not even sure if this is possible with Cfunctions, but since I'm still getting my head wrapped around the basics of Cfunctions, I could use some help. I need a Cfunction that will allow me to accept (Rx) serial data from another pin and send it into the console. (Allowing incoming control data from two sources at the same time {console and an additional pin) Either this is impossible, or I'm over thinking something that is simple. (not sure) Thanks Jeff My Propeller/Micromite mini-computer project. |

There is a CFunction, SerialRX - see http://www.g8jcf.dyndns.org/MMBasicIILib/ which enables a program to receive input from a pin and pass that data back to the calling MMBasic program, which could then PRINT that data to the console. Even simpler if you can use COM1: or COM2:, then it's all standard MMBasic to read characters off COM1/2 and PRINT them out to the Console - No CFunction required. Is that what you want Peter The only Konstant is Change |

I guess what I was really trying to do was change the function of another pin to perform the same job as a console pin which operates without having a program actually "running" in memory. I'm guessing this is well outside of a Cfunction task. My Propeller/Micromite mini-computer project. |

A CFunction must be called from MMBasic, so that means there must be a MMBasic program to start with, and it must have run so as to invoke the CFunction. The Console port is treated very specially by MMBasic hence I could imagine that moving the Console to another set of pins would be extremely non-trivial ! It maybe that someone, (and I'm definitely not clued up enough to do this), may find a way of using interrupts to call a CFunction so that even though the MMBasic program wasn't actually running (but clearly it must be loaded), the PIC32 would vector to the CFunction on interrupt from a pin.

Perhaps this is a case of x divided by zero so to speak - not possible? I'm trying to understand why you would need to have things setup like this. Could you please enlighten me? Smoke makes things work. When the smoke gets out, it stops! |
