I just checked it in LabVIEW: pass

(not yet available as a release. If you want to get at this code before it's properly merged, it's temporarily available via feature branch issue-47-without-patch-docker-linux)

Also great to see people contributing to the project!

Hope this isn't hijacking the post too much (I can create a new thread to discuss this if needed [mention:acaf6a9338de4eef8f6717d5561ed01d:e9ed411860ed4f2ba0265705b8793d05] )

Three new feature proposals (I'm not sure I can work on all these, but still it's interesting to maybe add them to the backlog if people think they are useful). Actually one is an enhancement, the other two are new features:

1) The analog input HIRES module enhanced to also support differential inputs and configurable gain
Example differential, gain of 4:


CONfigure:ANA:HIRES DIFFerential,4

Example single-ended, gain of 2:


CONfigure:ANA:HIRES SINGle,2

2) A new Board Memory (BM) module to suport cheap EEPROM on add-on cards for identification or for calibration parameters
First release to only support SCPI read/write in raw hex, useful for debug purposes

Example, write to card #0 (there could be several EEPROMs on the I2C bus, they can all be referenced by a card number which gets added to the base address which is 0x50 for most I2C EEPROMs, plus the card value which relates to the address pins on the EEPROM chip), 4 bytes 0xaa, 0xbb, 0xcc, 0xdd from address 16:


CONfigure:BM:RAW 0,16,aabbccdd

Read 4 bytes from card #0, from address 16:


FETch:BM:CARD0:ADDR16:4:RAW?

3) A new system temperature module to support the measurement of either ambient temperature of the system, or board temperature of individual cards. Card 0 would be ambient temperature.

Example to read the temperature of card #2 (this is assuming cards begin at #1, if zero will be ambient temperature):


TEMPerature:CARD2?

I'm not very good at thinking what the syntax should look like, the above is an attempt to keep some flexibility, but at the same time not making things too complicated or too large a bite for a first release of such functionality. But I suspect I've got things horribly wrong and broken conventions I bet, so I'm not too loyal to my own suggestions, I'd rather take as much advice as possible. Also tagging [mention:169a4014e923440aab0fa7af5203dabd:e9ed411860ed4f2ba0265705b8793d05] in case he has some advice based on his experience with similar intent type of commands perhaps.

Any suggestions welcome!

Very nice! Glad it was achieved, despite the difficulties with the library.
