Hello other members and guests.
I have my ShieldBuddy for some time now and starting to explore the possibilities.
Since I2C on the Arduino Due isn't working properly (read: not) and it is to slow for my use, I was glad I found the ShieldBuddy.
Now I'm curious on what others are trying to build with their ShieldBuddy and what challenges they have.
My goal is making a working datalogger that logs around 24 channels of automotive data to an external MySQL database.
For this I need basic things like I2C, SPI (SD-card and ethernet).
More specific:
Core 0: Timing and sending data to the database over USB-serial;
Core 1: 1 I2C-channel for retrieving data between 50 to 100 times per second;
Core 2: Task 1: SPI for a webserver that loads a website with "real-time" information via ethernet from the SD-card (Arduino ethernetshield);
Task 2: 1 additional I2C-channel for sending data to my 7 custommade onboard gauges.
Things I have to make/try:
1- Get the webserver running, SD-card info-sketch works, but the webserver doesn't.
2- Get I2C running on the ShieldBuddy, but I need 2 channels, because retrieving the data from a bunch of Arduino Nano's should not be interrupted by sending it to my gauges.
3- Get the second I2C channel working for my gauges.
If anyone has tips or tricks to get the SD-card webserver working, I'm interested, maybe I'm doing something wrong.
Like to hear about your projects.
Greetings from the Netherlands.
Johan.
