PBP and IDE/programmer

[robertg]

Hi,

Been many years since I've used PBP but back into it
Just upgraded from my 2011!!! PBP gold to the pro. and dusted off my pickit3
Downloaded PBP and installed fine.
But seems like not much has changed since 2011 as melabs online help still referring to CDROM installtion.
Microcode studio that was installed with pbp also seems old considering the pickit 3 is no longer supported MCS only list the pickit2 from the programmer list!
Eyes also started to glaze over as MCS isn't supported anymore and I need MPLABX.

I'm sure this is a well warn path but what can use as a windows development environment that is compatile with picbasic.

Thanks,

Rob.

This should point you to right direction

Thanks and appreciated.

It's a 10year old thread...hope it's still relevant.
What's happeend to picbasic? Besides the shopping aspect of the web site is still working all else has seemed to have ground to a halt?

That is true. People are getting old, things too!

Melabs will not develop PBP anymore and the latest version of PBP needs MPLABX assembler to work. Please DO NOT download the latest MPLABX. Only version 5.35 will work and obviously the PIC that this version supports.

Yes that is very true!

Hopefully some young enthusiast buys out PBP, I'd happy to be a VC for this. Keep me posted if you do hear of anything.

Haven't got a led flashing yet....but have managed to get MCS to run and download to the PIC so that's a start.


thanks again,

Rob.

We all hoped that PBP would find a way in the future but now I am convinced this will not happen.

People change, so microcontroller also do. Arduino, Pi, Python, and many many others are out there. PBP is considered outdated...

Can only hope!!! I think it still has a market, just product is not being marketed and it's a difficult experience to get started with.... IE

Can't get my first code running...

Have given up trying to get MPX to work even with the rev. you suggested.
Hence current on version 3.65 of mpx.Only need this installed for the pickit3 to work mcs.
I've got MCS now comipling and writing to the micro, but code doesn't appear to be executing.

Have tried a few variation of registeres but program is as follows:
#CONFIG
CONFIG FOSC = RC ;

#ENDCONFIG
TRISB = %00000000
LED0 VAR PORTB.2 ' Assign name "LED" to PORTB.0
LED1 VAR PORTB.1 ' Assign name "LED" to PORTB.0

mainloop:

High LED0 ' Turn on LED connected to PORTB.0
High LED1 ' Turn on LED connected to PORTB.0
Pause 400 ' Delay for .5 seconds

Low LED0 ' Turn off LED connected to PORTB.0
Low LED1 ' Turn off LED connected to PORTB.0
Pause 400 ' Delay for .5 seconds

Goto mainloop ' Go back to loop and blink LED forever

End

Via the program options of MCS using the PCK3cmd.exe from the MPLABX with the following command line:

-P$target-device$ -F$hex-filename$ -B -E -M -L

Programming seems to work but have no flash led! MCLR is held high..
I'm sure I'm missing somethign so obvious...but any pointers appreciated.

Rookie mistake should have had INTIO67 not RC for the clock!!

Ahhh

[Ioannis]

I hope you do not have many MPLABX version installed. Normaly they shouls co-exist but could also mess up things. Better be safe and uninstall all other version except 5.35 that works with the latest PBP.

As a programmer, I use Elnec BeeProg 2 and PicKit3 with a stand alone program by https://pickitplus.co.uk/Typesetter/ that supports Pickit2 and Pickit3 at the same app.

Thanks,

I've removed all other installs and switched to 5.35.

But I'm having problesm with 12F508 micros, seem like I get 2 chances to program the micro then, I get failed to program device error.
Swap out the micr and same thing. Purchased from Mouser so doubt it's a dodgie chip and it's definetely not a 12C508.
Scratching my head on that one!
I've ordered the programming software you pointed me to, just waiting on the license and see how that goes.

sounds like you have over written the osccal/ value stored at the top of memory for 12f508.
Most programmers will not reprog that chip when the value is missing.
The old pickit2 can reset a value there, with a bit of work. Pk3 might be able to do it too.
