Solution
What you will need for this recipe:
▪ Breadboard and jumper wires (see
“Prototyping Equipment”
)
▪ Nokia 5110 LCD (see
“Miscellaneous”
)
▪ 220 Ω resistor (see
“Resistors”
)
The Nokia 5110 LCD runs off of 3.3 V, so you can wire it directly to the Bone (
Figure 3-9
).
Figure 3-9. Wiring a Nokia 5110 LCD display
The drivers for the 5110 are in the Node Packaged Modules repository. Get and install them
by running the following commands:
bone#
npm install -g nokia5110
bone#
cd /usr/local/lib/node_modules/nokia5110
bone#
ln -s LCD_5110.js nokia5110.js
bone#
cp lcdTest.js /tmp
bone#
cd -
bone#
mv /tmp/lcdTest.js nokia5110Test.js
Edit
nokia5110Test.js
so that the first few lines specify how it's wired (as shown in
Example 3-7
)
and then run the code.
