FRDM KL-25Z is an awesome little board based on the MBED platform. And then, old school, home-brewed 8031/51 based boards, which, because of the ease with which you can access every part of the hardware, still kicks arse for some applications because there is no OS that gets in the way.
I hope I'm not too late. For now, do nothing.
First of all let's talk about the necessary and possible modifications.
This v1 Dock with Omega2 project is a lot of work... it may not be worth it.
Electronic circuits DIY and soldering practice are needed.
You have a version 1 Arduino Dock. Please let me know:
What is the SMD marking code of the power supply IC?
The MCU is an ATMEGA328P AU isn't it?
Make sure that the system is fully operative by using a delay as suggested by @fossette
As is mentioned in the referenced post, make sure the program you want to run at boot terminates in a timely manner and doesn't end up blocking the start up process - e.g. run it in the background
Hi! I'm trying to compile "arduino-dock" package from openwrt feed, but source code can't be retrieved from github. Here's the error:
Checking out files from the git repository...
Cloning into 'arduino-dock'...
ERROR: Repository not found.
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Hi, I have recently been revisiting building system images for the Omega and get exactly the same error if I include arduino-dock and similar for some other packages.
FYI: I have produced some small updates to the Omega Arduino Expansion Board design.
Added a jumper to allow Arduino VIn to be connected to the External Power Sources and the Power Regulator
Allowed for usage of TSR12450 power regulator (see https://www.adafruit.com/products/1065) as a compatible alternative to the L7805 regulator
@Anco-van-der-Kolk I will be writing the library in C/C++
While I am far from being an expert in Python, I believe the bulk of my library will be callable from Python just as is done with the current code for Neopixel control.
Though I have no idea as to how the interrupt from the Arduino to the Omega could be handled in Python - sorry
Regarding using a resistor bridge for change from 5v to 3.3v - yes, since the signal is only needed one way (Arduino -> Omega), this would be feasible if it is really needed.
Two suitably chosen resistors in series - one end to GND the other end to the Arduiono pin and the mid-point to the Omega pin
