DMP examples not architecture agnostic

[adamgarbo]

Hi @PaulZC,

Great work on the ICM-20948 library!

A quick note to let you know that the DMP examples make use of Serial.printf for displaying outputs, which is not supported on all platforms (e.g. SAMD21).

Cheers,
Adam

Thanks Adam,
If you've got a truly agnostic solution for this, I'm all ears...
Cheers,

Hi Paul,

I just replaced the printf commands with normal print statements. For example:

// Existing
SERIAL_PORT.printf("Q1:%.3f Q2:%.3f Q3:%.3f\r\n", q1, q2, q3);

// New
SERIAL_PORT.print("Q1: "); SERIAL_PORT.print(q1, 3);
SERIAL_PORT.print(" Q2: "); SERIAL_PORT.print(q2, 3);
SERIAL_PORT.print(" Q3: "); SERIAL_PORT.println(q3, 3);

I tested the above code with a SparkFun Qwiic Micro and it works well. I haven't been able to get the DMP examples to work with v2.0.5 of the Apollo3 Core yet, but the print statements should work just as well.

Cheers,
Adam

Okie dokie... Pull Request please? (I think you'll need to update all three DMP examples)
Thanks!

I had to update the examples for Version 1.2.1 - so I changed the Serial Prints too...
Closing...
Cheers!

Thanks, Paul! I'll keep my fork going for more testing and troubleshooting.
