Communication with LPM01A power consumption measurement board

[EWiebe]

Hello,

ST offers a power consumption measurement board which can measure very small current: 1nA .. 200mA

X-NUCLEO-LPM01A:  https://www.st.com/en/evaluation-tools/x-nucleo-lpm01a.html

My Question: Is there a LabView driver for this board? Has anybody implemented the communication in LabView or heard about?

(It needs communication over USB VCP (Virtual COM Port) with 3,6MBit/s.

It can be used stand-alone but can also be used as an instrument, controlled by commads.

Document about communication with the board:

Hello Eugene,

I have read all the tables, datasheets and documentations for the X-NUCLEO-LPM01A but found nothing about LabVIEW. I even requested information from Digi-Key Electronics (they also sell this board), but they were also unable to answer about connecting using LabVIEW. 😐

Hello Mr. Genius,

in LabView you simply open Serial Port which is from the board

with these Parameters:

Serial COM port configuration of USB-VCP (main interface):
– Baud rate: 3.6 Mbit/sec (3686400 bauds)(a)
– Data: 8 bit
– Stop: 1 bit
– Parity: none
– Flow control: none

And send the commands as written in

https://www.st.com/resource/en/user_manual/dm00418905-getting-started-with-powershield-firmware-stmi...

e.g. "volt 3300m" as written on page 22
