I’m using WPILIB 1.0.1 but I’m not able to get the included sensors to work. AnalogInput.getVoltage always returns 0.0 on channels 0, 1, and 2. I rolled back to PICO firmware and verified that the sensor hardware is working. How can I troubleshoot this?

Just to check, you’re using the 2024 version of WPILib right? (Latest version is 2024.3.1). Do you have a link to the code that you’re using?

I reinstalled firmware 1.0.1 and updated WPILib 2024.2.1 → 2024.3.1 and it worked. Thank you.
