This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the PWR SEL jumper.
Output enable pins are active LOW with enabled output drivers otherwise, with a high state, the display is turned OFF. The data is latched when those pins are in a low logic state. Those latch pins are data strobe input pins where serial data is transferred to the respective latch when they are in a high logic state. There are four additional pins, two for each TLC5926: data latch pins marked as LE1 and LE2, routed to the CS and RST pins of the mikroBUS™ socket, and display segment select pins labeled as NS and NS# routed to the INT and PWM pins of the mikroBUS™ socket. This Click board™ uses the SPI serial interface of the mikroBUS™ socket to communicate with the host MCU. The TLC5926 is a 256-step programmable global current gain with constant current adjusted by an external resistor in this case, it is kept around 8mA per segment.
Two TLC5926s drive this display with constant currents in the sink configuration.
The fifteenth segment of each set is a comma, suitable for displaying a decimal number. The segment forms part of a numerical digit (decimal and hex) or ISO basic Latin alphabet to be displayed when illuminated. This display consists of two sets of 14 LEDs arranged in a rectangular starburst fashion, where each of the 14 LEDs is called a segment. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.ĪlphaNum R Click is based on one red two digits 14-segment alphanumeric display with leading dots and two TLC5926s, 16-bit constant-current LED-sink drivers from Texas Instruments. This Click board™ is suitable for many applications requiring a visible display or others that display numerical/textual information.ĪlphaNum R Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. In addition to the regular segments, these displays have commas for displaying decimal points if used for digits. Each 14-segment display digit (also known as a starburst display) is driven by one of the LED drivers capable of lighting every segment to render the ISO basic Latin alphabet legibly. This board features one red two digits 14-segment alphanumeric display with leading dots and two TLC5926, 16-bit constant-current LED-sink drivers from Texas Instruments. AlphaNum R Click is a compact add-on board representing an easy solution for adding numeric or hexadecimal displays to your application.
