History

Added support for CD4067 multiplexer on I2C bus default tip

Added support for CD4067 multiplexer on I2C bus


Support for 74HC4067 4-to-16 analog Mux now complete. We now use a PortOut pointer to specify the four control pins connected to the MUX and the mux value to write to the pins before an I2C command is executed.

Fixed display offet issue whereby the start line was not reset back to the top of the screen during a reset, and sometimes moved during normal operation.

Code space optimizations;; Make simple set/getter functions inlined.; Fix ifdef around setTextSize() to be either GFX_WANT_ABSTRACTS or GFX_SIZEABLE_TEXT; ifdef drawBitmap() w/ GFX_WANT_ABSTRACTS.;
