Lcd Functions Overview
Description
Lcd functions allow scripts to interact with the transmitter display. This access is limited to the 'run' functions of One-Time and Telemetry scripts. Widget scripts on the Horus (X10 and X12S) can make use of the lcd functions as well.
Notes:
The run function is periodically called when the screen is visible. In OpenTX 2.0 each invocation starts with a blank screen (unless lcd.lock() is used). Under OpenTX 2.1 screen state is always persisted across calls to the run function. Many scripts originally written for OpenTX 2.0 require a call to lcd.clear() at the beginning of their run function in order to display properly under 2.1 and 2.2.
Many of the lcd functions accept parameters named flags and patterns. The names and their meanings are described below.
