Library for running 7-segments displays with TPIC6C596 drivers
Software to control 7-segment displays.
This code is further improved to easily support multiple displays, as well as text/numbers, with scrolling.
Tested with the following hardware:
- 7-Segment Display - 6.5" (Red)
- SparkFun Large Digit Driver
- RaspberryPi 4
- SN74AHCT125N Quadruple Bus Buffer Gates With 3-State Outputs
- Adafruit Perma-Proto HAT
12v power to the displays are provided externally.
In our case, we swapped the Arduino with a RaspberryPi 4. As the Pi operates with 3.3v signals on the GPIO compared to the 5v of the Arduino, the signal lines (clk, latch, data) needs to be adjusted via a logic level converter.
Segments class parameters, based on the Raspberry BCM pinout:
- bcm_gpio_clock=11 (CLK)
- bcm_gpio_latch=13 (Signals when to switch to the next display)
- bcm_gpio_data=14 (TXD - used to turn each segment on/off)
- num_displays=7 (The number of displays you've chained)
- debug=False (Turns on debug output to console)
- offline=False (Deactivates the actual GPIO-parts, used mainly for dev/tests)
