Add new board on Arduino IDE V2

[lastguy]

I am not sure why I cannot add .json using V2. I want to use Attiny85 but not sure which file defines its pin names. thanks for help.
On V1 how do I add a .json file? e.g: http://digistump.com/package_digistump_index.json

I think I just used the attiny*5 for the chip and the attinyCore... don't remember adding anything else...

Hi @lastguy

@lastguy

I'm not sure either. The reason is because you haven't provided any information about the problem you are having and I'm not psychic.

Please provide a detailed explanation of the problem you are having, including:

• What did you do?
• What were the results you expected from doing that?
• What were the results you observed that did not match your expectations?
  • Make sure to include the full and exact text of any error or warning message you might have encountered.

I want to use Attiny85 but not sure which file defines its pin names.

Here it is:

digistump/DigistumpArduino/blob/1.6.7/digistump-avr/variants/digispark/pins_arduino.c

But I recommend you to focus on getting the boards platform installed first.

By the way, you should only use the Digistump boards platform if you have a Digispark board (or a Digispark clone). You should not use it with a bare ATtiny85 chip or a board that does not have the VUSB circuitry like the Digispark. I can recommend an alternative platform for use with ATtiny85 that are not in the Digispark configuration.

On V1 how do I add a .json file?

1. Select File > Preferences from the Arduino IDE menus.
2. Enter the URL into the "Additional Boards Manager URLs" field.
   If there are already Boards Manager URLs in the field, separate them with commas.
3. Click the OK button.

yes on V1 I can do it. but not V2 - weird.

Again, if you will take the time to tell me what the problem is, I'm certain I can help you to accomplish your goal.

Thanks for all helps. I stopped here as I found attiny85 has no enough RAM for SCoop multitask.
Although there are a few multitask core in V2, I think SCoop still better.
Use nano is ok for me thanks again.
