Qwiic Micro question as related to the RedBoard Artemis Nano

Qwiic System
1

Hello!

Would someone confirm or refute this one? Is the processor on the Qwiic Micro not related to the one inside the RedBoard Artemis Nano?

I ask because I have the example for the Artemis Nano running on it, with the LiPo Fuel Gauge and the Qwiic OLED display showing me the charge level on the battery, and also the voltage stored from last time. And after I add a JST socket to a Qwiic Micro, (Due Thursday) I want to see if the same example will run.

What sparkfun part numbers are you asking about?
“Qwiic micro” returns many search results, nobody knows what you have.

Hello!

It might have been obvious. But here goes:

“SparkFun Qwiic Micro - SAMD21 Development Board SKU: DEV-15423”.

That is the device I am thinking of.

They are not related.
One has a SAMD21 processor, the other has an Artemis (Cortex-M4F) processor.

It’s very likely code for one will run on the other but it’s possible you might need to make some small adjustments.

Hello!

I actually did expect that. But code from the example, displays on an attached via Qwiic connectors an OLED display. Which is shown as:

SparkFun Micro OLED Breakout (Qwiic) SKU: LCD-22495 on the Fritzing screen. And indeed that’s what I used both this time at first, and then earlier, when trying out the Fuel Gauge device.

I decided to try out, instead SparkFun Qwiic OLED - (1.3in., 128x64) SKU: LCD-23453 to see how it would look. About what I expected to be honest. It exactly looks better on that one.

Also the Arduino IDE is used to load the code on the Artemis Nano, wouldn’t switching the board selector to the other board, the Qwiic Micro SAMD21 instead, simply mean that the IDE simply swaps tools around? One setting for the other, I mean.

More-or-less, but the IDE only attempts to route things to account for the hardware differences from board to board in regards to their programming, while the arduino libraries remain unchanged based on board selection (he’s saying you might need to edit the sketch to account for pin # changes, potentially different baud rates, etc)

Hello!

(I changed things since the earlier one needed approval.)

By that you mean how the setup will understand the Qwiic connector pin numbers? Yes I did infer that much.
