The BIG 7-Seg R Click Board™ is what you need if you want to add a seven-segment LED display to your project. This Click Board™ features an SC10-21SRWA seven-segment display. Communication between the MCU and the SC10-21SRWA display is established via serial-IN, parallel-OUT shift register 74HC595 IC.
The BIG 7-Seg R Click Board™ runs on either 3.3V of 5V power supply and communicates with the target MCU over an SPI interface.
The BIG 7-Seg R Click Board™ displays letters, numbers and symbols in highly readable form. It can be used in any simple interface and combined with other Click Board™s. The color of the displayed character is red, as the R in the name of the Click Board™ states.
The light intensity on the display is controlled via the PWM pin on the board.

This demo is using the BIG 7-Seg R Click Board™ to display characters in an endless loop, with fixed time interval whilst changing its PWM duty.
This example for STM32F107VC MCU ( EasyMx PRO v7 for ARM ), resets and initializes the BIG 7-Seg R Click Board™ takes characters from the static array and displays them while changing PWM duty cycle, all in an endless loop.
