I also have a 7" display (1024X600) that I could use. What I don't have is any info on hooking all this up and programming the PI to run Lady Heather. Is there any place on the Web that would provide me info on getting all this together and programming it ?

If you are using a USB-Serial converter the code should work as-is. Heather does not have any code specific to a particular type of hardware (such as the PI). If you are using the PI GPIO serial port, you would need to modify the program to manipulate some GPIO pins. This is probably best done in the functions SetDtrLine() and SetRtsLIne() in the heather.cpp file... there are Windows and Linux versions of these routines. The functions apply_heat() and apply_cool() and hold_temp() in heathmsc.cpp could also be modified. There is also some code to use a parallel port to control the fan, but that is rather Windows/DOS specific. It could be modified for Linux. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
