Board.txt What am I doing wrong

[six]

Ok so I make my own PCBs and I want to use Pin 8. Oddly as a SS but I have multiple slaves so I wanted to be explicit in setting it. That lead me down a rabbit hole where I learned about Digital 17 and 30 for RXLED and TXLED. As I never bother with those ANYWAYS on my hardware, I decided to see if I could reclaim them. Turns out I can by null defining those functions in pins.h

From what I read I jsut needed to create a Variant folder and copy the pins file, in this case the Leonardo version as I love me the 32u4. well I love it when I'm not able to sqweezes me gadget onto an ATTiny 1604/1634 Sorry getting side tracked. So I made the edits to the pins file then I followed a how to for adding the vattiant to the IDE and it said to make an entry in Boards.txt

I more or less cloned the Leonardo and renamed everything I thought I should rename. Then saved it and relaunched the IDE. But the board is no where to be found. What am I missing>

Hi @six. Cool project!

It is important to know that the platform in the hardware/arduino/avr subfolder of the Arduino IDE 1.x installation is only used if you haven't ever installed the "Arduino AVR Boards" platform using the Arduino IDE Boards Manager. Boards Manager installs the platform to a completely different location on your hard drive and after that the copy of the platform bundled with the Arduino IDE installation is no longer used.

You can determine the location of the active platform by examining the verbose output from compiling for one of the boards of the platform. I'll provide instructions:

1. Select File > Preferences from the Arduino IDE menus.
2. Check the box next to "Show verbose output during: ☐ compilation".
3. Click the OK button.
4. Select Sketch > Verify/Compile from the Arduino IDE menus.
5. Wait for the compilation to finish.
6. Click on the black console panel at the bottom of the Arduino IDE window.
7. Scroll the panel all the way up to the top.
8. Look for the line that starts with "Using board ...".
   For example:

   Using board 'uno' from platform in folder: 
   C:\Users\per\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.6
   

The path you see in that output line is the path of the active platform for the board. You must make your modifications there.

Facepalm! I'll have to try it in the morning. But I'm pretty confident you're right! I feel like a silly Billy! That seems pretty obviously the right answer so I bet you're right!

YUP! that works!

I'm glad it is working. Thanks for taking the time to post an update.
