# On Jetson, use the jetson-io to enable SPI1. Steps are shown in the [https://www.waveshare.com/wiki/1.5inch_LCD_Module#Jetson_Nano_User_Guide Jetson Nano section in the 1.5 inch 5in LCD Module guideGuide]. Follow the "Enable SPI" and "Library Installation" sections. Stop before the "Download Example" section.

# Clone You may also need to run "sudo modprobe spidev" to get the spidev driver loaded.  The example code should draw some shapes every 2 seconds, followed by the repository Waveshare logo, then a Yuan dynasty poem, and lastly a series of images.  == Testing with 2 LCDs ==Ideally, we run both screens off the same SPI line and use the built-in chip-select pins on the Jetson. However, based on current testing, the Jetson-IO CS functionality does not work. If a device is connected to CS1 and CS0, CS0 will always remain low. The codein the repository assumes you use both spi lines (SPI0 and SPI2, so spidev0.0 and spidev2.0 respectively). You may need to install  Wire up the second display as such:  {| class="wikitable"|-! Function !! Jetson Pin !!
