7x10 R Click Board
A Multi-Faceted Display
The 7x10 R click performs the operation of carrying a matrix of 70 red LEDs driven by a pairs of 8-bit serial-in, parallel-out shift registers, a Darlington Transistor array and a Johnson counter. It communicates with the target MCU through the mikroBUS™ SPI interface (SCK, SDO, SDI), with additional functionality provided by R CLK, MR#, LATCH and R RST pins.
The display is driven by four different chips-a pair of serial-in parallel-out shift register that take the input from an MCU through the mikroBUS™ SPI interface and a Darlington transistor array that amplifies the current enough for lighting up the LEDs. The 7x10 R click is also equipped with Johnson counter IC which does the LED multiplexing, turning LEDs on and off rapidly.
