Latest PICs - how to program them?

[tumbleweed]

A lot of it really depends on what your ISR is doing.

Just like PBP you can choose to save just the pic registers or also include the BASIC system library variables.
SF has the additional complication due to the shared frame variables, a powerful feature which can reduce RAM usage a LOT.

If saving the context is really complicated that's a good clue you should probably examine what your ISR is actually doing in the first place... most folks do WAY too much in the ISR.

In most cases it's not nearly as complicated as it sounds, but the nice thing with SF is that you can easily control what gets saved without having to resort to editing asm libraries, etc., and can be done on an individual case-by-case basis.

All things have two sides. Same with SF of course. This design of the compiler has great potentials but needs great care by the user/programmer.

I agree that produces more compact and faster code. Especially with the new tool that was offered.

Just checked the supported list of the MCUs supported by Positron Compiler. It is big and surprising...!

Many dsPIC, 24F, 24H and Q series...!

Just see the amazing and cheap PIC18F57Q43.

Support for the 16-bit pic24/dspic33 parts is one of the nice things about Positron.
But, if you thought SF was a bit quirky Positron is possibly worse in that regard.
As you say, each have there own strengths and weaknesses.

As far as the 18F Q series goes, it only supports the same parts as PBP does (Q10, Q43).
That's an MPASMX 5.87 limitation, and neither PBP or Positron can do much about that.

In fact, I got a quick reply from MECANIQUE - unfortunately I didn't see their email because it landed in my spam folder (...)

Here is the info:

Hi

If the device is supported in PBP, it should appear in the IDE. The IDE collects supported devices from the PBP install.

You do not need to upgrade MCS.

You might have to upgrade PBP.

Can you give more details on this please?

PBP can use MPLABX 5.35 only.
