mikroC demo version limits

[ssylee]

I may have to switch back to Windows for PIC control development for PIC18F2620 and make sure that I don't wire up the programmer headers incorrectly (or it will freeze again). I'm planning on going with the demo version on https://www.mikroe.com/en/compilers/mikroc/pic/download.htm. There's a limit on the hex file for the program word being 2k. So how many commands/complex my control code can it be before I exceed the program memory limit for the demo version?

Don't know about mikroC, but using Basic with a datalogger project will probably put you at the limit. In my case, multiple 1-wire temp sensors, I2C eeprom and RTC, and a Uart for serial LCD.

I'm planning to program in C for a datalogger project, which I guess would likely put me over the limit. I'm also relooking into using MPLAB, but unsure what's the limit on the student version of the C18 compiler.

 

[nickelflippr]

You probably would be safe if you instead used an internal timer and a PC for display purposes, it really depends on your requirements.

 

[ssylee]

I would most likely have an LCD connected to it for display purposes when needed, so I would likely be over the limit with my guesses.

Using MikroC

I'm from Serbia from where the MikroC is. I have tried it and the demo version is very limited. I have tried to do some GLCD programing but the generated code for only a one string conversion from float number were exceeded the demo limit. I'm using now CSS C which is very good and I'm satisfied with it. I would advise you to try it if you want a very optimised code.

There is no size limitations in C18 compiler. Code compiled after 60 days won't be optimized (=bigger) but as long as the program memory of your PIC is large enough you'll have a fully functional hex file.

 

[ssylee]

Probably another dumb question: how much bigger would it be (in terms of percentage) typically for non-optimized version of the hex file. PIC18F2620 has 32,000 words of program memory available.

Obviously it depends on the particular program, but I wouldn't worry about it, you have a HUGE amount of space available, and it's only slightly larger.
