Description:
The 0.56" 7-Segment LED display from Adafruit with I2C backpack has a decimal point on each digit which may used in the display to show a floating point number.
Added support for this display, and also code to allow showing floating point number, as well as addressing every addressable segment of every digit.
This fix adds the f and r modifier prefixes to
xdsp_11_sevenseg
display driver:From the code:
To address raw segments for digit n, use the Console command with
DisplayMode 0
:DisplayText [x
n]
mwhere n is in range 0..4 which specifies which digit of LED display (including : at position 2) and m is the bitmask to select individual segment. Reference: https://cdn-learn.adafruit.com/downloads/pdf/adafruit-led-backpack.pdf.
Examples:
DisplayText [y0x0]r255
turns all the segments of left most digit of first LED display on, giving:8.
DisplayText [x0]r62[x1]r243
displays:UP.
