The SLED4C provides a simple 3-wire synchronous serial interface to a high contrast, four-digit seven-segment super red LED display module. Using the SLED4C reduces the number of MCU I/O-pins for display control from 13 to a mere 3 I/O-pins. These 3 I/O-pins control 35 individual LEDs on the display module consisting of four seven-segment display digits, four right-hand decimal points, two LEDs for the colon, and one additional upper right-hand decimal point.

Embedded designs integrating colorful and highly visible 4-digit LED displays will recover up to 10 valuable MCU I/O-pins for other tasks, and multiple SLED4C display modules can share a common serial bus. Sharing the data and clock pins on the serial bus allows additional display modules to be added to the design with only one I/O-pin required for each additional display module enable pin.

BASIC Stamp code examples include;

Count from 0 to 1000, Lamp test with 8.8.:8.8. + blinking, 4-digit clock from 16:50 to 17:00 w/blinking colon, Another counter with colon ON, count on right 2, then on left 2, Display H.E.L.P. pulsing brightness from 50% to 100%, Count from 9994 to 0000 at 50% brightness, Display OUCH pulsing brightness from 50% to 100%. A program to display the
current time on the SLED4C using the Dallas DS1302 RTC IC.
Note: Click HERE for an online BASIC Stamp project using the SLED4C.

CCS C Compiler code examples include;

Displays time & temperature on the SLED4C serial LED display module with the DS1620 temp sensor & DS1307 RTC. When the temperature >= the high alarm set point display OUCH message. Below set point, display temp in normal mode. This could also be used to trigger an alarm relay, thermostat, etc,, MAX temperature range is from 0 to 99

PicBasic Pro Compiler code examples include;

Count from 0 to 1000, Lamp test with 8.8.:8.8. + blinking, How to use display power-down mode, A 4-digit clock displaying from 16:50 to 17:00 w/blinking colon, Counter from 00 to 14h with colon ON + 100% bright, count on right 2, then 50% on left 2, Display H.E.L.P. while pulsing brightness from 50% to 100%, A counter from 9994 to 0000 at 50% brightness, Display OUCH pulsing brightness from 50% to 100%. A Digital Clock w/ Time & Temp using the Dallas DS1620 & DS1307 RTC
