Post by thread:program works before burning

whats the best way to test to make sure the program works properly before burning it into a PIC12c50x , since their o.t.p. do i get a uv eraseable PIC12c50x (>$31.00 each -1offs-farnell) to do all initial tests on , then erase after each test burn , till i get bugs out or otherwise it could be very expensive testing if you have to use a new pic12c50x everytime,before you get it right . is their a simultor for this thanks for your time & help glen

If you are talking about modifying the code to the application when sometimes it works good on the simulator but poses other problems in service, get an EPROM version. > do i get a uv eraseable PIC12c50x (>$31.00 each -1offs-farnell) to do > all initial tests on , then erase after each test burn , till i get bugs > out or Thats what I am doing...Using a EPROM peice until I get everything like I want then I will go to OTPs. > > otherwise it could be very expensive testing if you have to use a new > pic12c50x everytime,before you get it right . > > is their a simultor for this > MPLAB 4.0 from Microchip lists the chips you are talking about, and its a simulator.

(Parallax). when i learned (!) that the JW part does not like 9 volts supplied where 5 was called for (never mind exactly how *that* happened) i was dead in the water. i got some mileage using a simulator. i usually rough out the code that way anyway. what i did to get back on the air until replacement JW parts come in (are they out of stock everywhere they don't sell for $31?) was to lash up a 16F84 onto an 8-pin socket so that it would look and act a lot like a '509. worked pretty good and i only got burned (so to speak) once by using a little more stack depth than actually exists on the '509. -- rob

Check the http://www.iversoft.com/piclist/ archives for a porting checklist I wrote last year. Helps one to write code that works on 16F84 and 12C509 at the same time. I tried searching for it then, but the search engine couldn't find me, and it could not find 12C509 either! I suspect a fault with the engine. -- James Cameron (spam_OUTcameronTakeThisOuTstl.dec.com) OpenVMS, Linux, Firewalls, Software Engineering, CGI, HTTP, X, C, FORTH, COBOL, BASIC, DCL, csh, bash, ksh, sh, Electronics, Microcontrollers, Disability Engineering, Netrek, Bicycles, Pedant, Farming, Home Control, Remote Area Power, Greek Scholar, Tenor Vocalist, Church Sound, Husband.

See below. > is their a simulator for this Yes, the MPLAB package has simulators for all the Micro-controllers it can program. But ! Simulators simulate. They _can't_ give you the exact behavour of the device itself (and MicroChip does not simulate _all_ features of the chips ...). > thanks for your time & help > glen Greetz, Rudy Wieser
