add new target: cryptoauth trust platform

[hugolgst]

I would love to see the CryptoAuth Trust Platform being added.
It uses ATSAMD21E18A which is already implemented.

I can't get this code to blink the LED. Any idea why?

Here are some information about the chip: https://ww1.microchip.com/downloads/aemDocuments/documents/SCBU/ProductDocuments/BoardDesignFiles/DM320118-schematics.PDF

It seems to flash ok but the LED is not blinking

I think it should be something like this instead:

var led = machine.LED
led.Configure(machine.PinConfig{Mode: machine.PinOutput})

[hugolgst]

Yes but since it is a custom board I did not set PinOutput in the board's file yet.

[conejoninja]

Ummm, but no need to re-define the PinOutput, since it's already in the machine_atsamd21.go file https://github.com/tinygo-org/tinygo/blob/release/src/machine/machine_atsamd21.go#L29 plus it should be 11 not 0

Also, let's try with

var led = machine.LED

instead of

var led machine.Pin = 2

[hugolgst]

right, I was confused with something else. Now I am indeed using LED and PinOutput, it was just this. I can't thank you enough for your help. Better read the documentation well next time.

I will try to clean out everything and make a pull request to add my board.

Have a nice day

[conejoninja]

No problem!
Adding a new board should be easy as long as the chip is already supported like this case.

I proceed to close this issue, please open a PR when your new board is ready!

Thanks for your work
