Note that the RabbitFLEX BL300F LCD driver is intended to support modules based on the Hitachi
HD44780 chipset, but we cannot guarantee compatibility will all LCD modules based on this chipset. To
ensure compatibility, use the LCD module that we provide for the RabbitFLEX BL300F.
After the display has been initialized, there are a number of functions to display text, manipulate the cur-
sor, change the contrast, turn the backlight on and off, etc. See the flexDisp*() functions for more
information.
6.3.8 Speaker
The loudspeaker option can be used with two drivers: the tone driver and the audio driver. The tone driver
is intended to play a repeated tone for a specific number of repeats (or indefinitely). The audio driver is
intended to play a single audio sample. Tone driver functions begin with flexTone, and audio driver func-
tions begin with flexAudio.
To begin using the tone or audio drivers, you must first activate them with flexToneActivate() or
flexAudioActivate(), respectively. When activated, the drivers will consume about 10-20% of
your CPU. Thus, after you have played a tone or sample, you may want to shutdown the driver(s) with
flexToneShutdown() or flexAudioShutdown().
See the speaker_tone.c and speaker_audio.c for examples on using these drivers.
