node-red-node-pilcd =================== A Node-RED node for a Raspberry Pi to write to a GPIO connected HD44780 style LCD panels. Install ------- Run the following command in your Node-RED user directory - typically `~/.node-red` npm install node-red-node-pilcd Usage ----- Raspberry Pi output to HD44780 style LCD module - typically 1, 2, or 4 lines. It must be configured with a comma separated list of pins that are wired to the LCD panel. Pins MUST be a comma separated list of the 6 GPIO connector pin numbers that are connected to the RS, E, D4, D5, D6 and D7 pins of the LCD. e.g. 26,24,22,18,16,12 Send the node a `msg.payload` with a string in it. Strings for the 2nd line of the display must start **2:** - the third start **3:** - and the fourth **4:** - For example 2:I'm on line two 4:and this is on line 4 1:or indeed line 1 The `1:` is not necessary for line one but is there if you build lines using a template, To clear the display send the string `clr:` It is up to you to manage string lengths to suit the display. Requires the RPi.GPIO python library version 0.5.8 (or better) in order to work. **Note:** we are using the actual physical pin numbers on connector P1 as they are easier to locate.
