Using the OpenLog to log data from a different device

Other
1

Hello!

I own several OpenLog devices, I also own a number of devices from Adafruit which can be programmed using the Arduino sketch concept. One of theirs is the 32u4 equipped device, which is the “Adafruit Feather 32u4 Basic Proto”. I’d like to use one of the OpenLog devices to record data streaming from the serial port common to Arduino styled platforms. Please note that these Feather devices are some what nonstandard in their layout.

An OpenLog could record the output of Serial1 on the 32U4 Feather (pins labeled RX, TX), but not the native USB Serial output.

Hello!

I agree. I don’t plan on logging data from the USB port, its only used to program it. The conventional serial1 port is used.

Hello!

This is aimed towards the Sparkfun staff people directly.

Something else, the examples all show the DTR connection on the log shown as connected to the DTR connection on the target board. Will it matter on a board that doesn’t have such a port?

Hello!

Something else I did not include when starting this discussion: (Quote from website)

“Note: The latest version of the firmware (included with this board) does not compile in Arduino 1.6.7. You will need to compile in 1.6.5.” How is this still valid when the Arduino people are actively promoting version 2.3.6?

Because the firmware was developed when 1.6.5 was current and likely relies on a bug or “feature” present in 1.6.5. Arduino has made some pretty radical changes to the IDE over the years, those changes broke a lot of older code.

Unless you know what you’re doing, you don’t have a reason to be mucking about with the firmware anyway.

You don’t need DTR, just power, ground, RX and TX.
