LINX - I2C

[renesuza]

i have installed the LABVIEW hobbyist toolkit (2021 version) for accessing I2C block sets through the NI package manager. when i try to open in Blank VI it was displaying a question mark. what can i do to prevent this. whether can i use the VISA-> read, write peripherals for alternative LINX-> I2C-> read, write peripherals. 
LABVIEW Version: 2019

Hi renesuza,

Regarding the question marks:

This seems to be an issue with the installation files not being where they should be. Please see the corresponding Knowledge Base article: Question Marks in Block Diagram - NI. Given the question mark icon, I assume the LINX vi is not working as expected, right? Let me know if you get any error codes / messages.

Regarding your second request:

I am not sure if VISA can be used instead of LINX. What is your hardware setup and which device do you want to program?

Best regards

Leonard
