Salut Matt,

in the past weeks I used DP32 as board setting even when using my HelvePic32 as I was switching between the two boards all the time. Tonight I selected HelvePic32 as board and I get weird errors: on the blink script:

c:\uecidebeta\compilers\pic32-tools\bin\bin\gcc\pic32mx\4.8.3\..\..\..\..\bin/pic32-ld.exe: MPIDE Version not specfied correctly

collect2.exe: error: ld returned 255 exit status

on the I2CMasterEEPROM:

Failed compiling libraries

Looks like the HelvePic32 definitions are missing some flags. Compiling with DP32 board selected works ok.

Ciao, Mathias

Quute possiboy some things got missed with some of the changes to the Wire library. I will look at it today and upload a new set of defs.

Yep, I thought so - that board definition got missed with the upgrade from TWI to DTWI for the Wire library (and others). It's a very simple fix, I just need to know which pins the I2C is on. I'll see if I can find the nice picture you have of it to find them :)

Ok, new defs uploaded to the repo. It should all work now.

UECIDE shows Board: HelvePic32 Core: PIC32 Compiler for MX and MZ version 4.8.3

Strange ... (maybe because I am in London now? ;)

Well....

I changed the options->optimization from "smallest size" to "Fastest execution" and it linked. When I then switched back to smallest size it linked as well.

This is something I have been seeing myself with the new compiler. If it hiccups for whatever reason a subsequent compile whinges about the MPIDE version. The quickest solution is to hold SHIFT and click compile. That forces a purge before compiling, and the compile then works fine. By switching optimizations you also forced a purge before compiling.
