Hi Phil Your code looks reasonable, thanks for your help. In my original code I should have separated (abstracted) the pump control logic from the probe...

Thank you,phil for all the work you are doing on this. I take it you have to enter the code for each probe? I did try to generate a hex file,but Mplab turned...

Sorry Jeff - my fault! You can't carry out a RLF/RRF on the accumulator, so need a couple of extra lines: DoingManifold BCF RX_STATE, RX_FRUZ_BIT ; not...

You say you were able to monitor the rising temp in Hotbox. What sort of temperatures were you recording? Did they seem to be the right sort of values? For...

Phil,yes the temp readings seemed to be accurate for each probe.I took the manifold probe to about 80 deg,which should have been well enough to start the...

Hmm - well, if the readings are right, then we have accomplished the original aim, of getting the right temperatures from the probes. If the pump is not coming...

I'd suggest you throw away the "cont 208" code, and adapt the newer arbiter code to perform the controller function. The "cont 208" code never knew about...

Hi Jeff - had you considered using the arbiter with as many probes as you like, and using a PC as the controller? Small, skeleton PCs can be obtained very...
