Is this a possible configuration for the OpenLog Artemis

Development Boards Artemis
1

Hello!

I am currently planning out and working on some project where I would be using both a redboard artemis and a openlog artemis together. The redboard is there to have a sleep mode and the main loop I want. The OLA would be used for getting its IMU Data, however it shouldn’t log that data immediately, and rather only log that the redboard sends over serial. Is this possible or am I missing something?

Yep, that’ll work great - see the config section here for more info about how to set the OLA up for such

Hi Inuka (@InukaSilva ),

“however it shouldn’t log that data immediately, and rather only log that the redboard sends over serial.”

Can you please explain this a little more? Do you want the redboard serial data to “trigger” the logging of the IMU data?

Best wishes,
Paul

Hello!

I guess the best way of explaining it is that the OLA is only used to send data to the redboard artmis, which would then collect and format the data back to the OLA to be saved. This is because I will be adding some sensors that would use BLE to relay back to the redboard, but since there is no built in micro SD card slot it would need to be saved on the OLA.

Hopefully this helps in describing the set up that I am looking at doing.

Hi Inuka (@InukaSilva ),

OK - thanks! I think that will work. There is an option to “Output serial data to TX pin” - see “Configure Serial Logging” in the hookup guide. That will allow you to send the IMU data to the Redboard. The OLA can still “Log serial data” from the RX pin while in that mode.

But, for your application, it might be easier to add a SPI microSD breakout to the Redboard and do the logging directly there?

Good luck - sounds like an interesting project,
Paul

I was just going to use the OLA and redboard since I had it on hand, I think in a future iteration it probably would be best to use a breakout board for a IMU and a SD card slot. When the OLA is put into this mode, would it only log the data from the RX pin or still log the iternal IMU data?

You can set it up either way :slight_smile:
