MECH 488/588 Students

See the wiki for instructions on the project

Initial Setup (MECH 488 TAs only)

myRIO Hardware

• Install LabVIEW myRIO Toolkit 2019 (32-bit).
• Connect the myRIO via USB to host PC and find the device in Measurement and Automation Explorer (MAX) under Remote Systems.
• Ensure that the current firmware version is 7.0.0f0. If it is not, click the Update Firmware button and install the latest firmware.
• Ensure Enable Secure Shell Serve (sshd) is enabled.

• SFTP the FPGA bitfile from mahi-daq/misc to the myRIO device:

cd mahi-daq/misc
sftp admin@172.22.11.2
cd /var/local/natinst
mkdir bitfiles
cd bitfiles
put NiFpga_MyRio1900Fpga60.lvbitx
chmod 777 NiFpga_MyRio1900Fpga60.lvbitx

Cross-Compiler

• Download and install the NI ARM cross-compiler to C:/dev/nilrt-arm so that the directory contains sysroots/, relocate_sdk.py, etc.
• You must also install ninja (recommended to use chocolatey to run choco install ninja).
• Once this is installed, you should be able to use the [nilrt-arm] kit with CMake Tools in VSCode to compile for the myRIO from Windows.
• Otherwise, mahi-daq ships with a CMake toolchain file, which can be used like so:

> cd mahi-daq
> mkdir build
> cmake .. -G Ninja -DCMAKE_TOOLCHAIN_FILE="../cmake/nilrt-arm-toolchain.cmake" -DCMAKE_BUILD_TYPE="Release"
> cmake --build .

Firewall

• If you notice that the pendulum GUI is not receiving packets from the myRIO, you may need to update Windows firewall settings. For every instance of pendulum-gui, allow all settings as shown below:
