T400 Delimiter Extra Spaces

Any chance the space after the comma could be removed in the CSV files from the T400? When reading into most graphing programs, the columns come in with spaces before each column name and spaces before the values or '-' placeholder. It makes the user do some extra data wrangling to get things plotting nicely.

This could be done by modifying the firmware. Should be pretty simple. Would you post a few example likes of the out output format you'd like?

I think a lot of folks can handle trailing spaces. I am most concerned about the leading spaces on the time stamp and the use of a "-" for no data. A lot of the time programs mark missing data as -999 or something similar. Any interest in using that?

Do you have one of the units shipped as a Kickstarter reward? Since then the leading spaces have been removed.

With the most recent firmware in the serial terminal I get:

File: LD0075.CSV
time (s), temp_0 (C), temp_1 (C), temp_2 (C), temp_3 (C)
1, 25.9, -, -, -
2, 25.9, -, -, -
3, 25.9, -, -, -
4, 25.9, -, -, -
5, 25.9, -, -, -
6, 25.9, -, -, -
1, 25.9, -, -, -

In the CSV file I get:

time (s), temp_0 (C), temp_1 (C), temp_2 (C), temp_3 (C)
1, 25.9, -, -, -
2, 25.9, -, -, -
3, 25.9, -, -, -
4, 25.9, -, -, -
5, 25.9, -, -, -
6, 25.9, -, -, -

Here's a screenshot of both.

This one was sent recently to use on the blog (post is drafted!) I can try to update to the most recent firmware and see if things change.

Haha I remember now. I must have sent that out with the older firmware. Does your's have a serial number sticker? If so, what serial number do you have?

I'm on travel for about another week, but will let you know and then update.

This is T400-151, so early firmware?

Looking back in my I see that all T400 units have the same firmware (t400-1.0.hex). It was only the bootloader that changed: Units with serial numbers T400-000 to T400-099 have Caterina-T400-1.0.hex while T400-100 and above have Caterina-T400-1.1.hex.

I must be running a development version on my T400. When I get back home I can flash version 1.0 and confirm that is has the same behavior as you T400.
