Detailed Description

A 7-segment LED interface for driving 4 seven-segment LEDs connected via two cascaded 74HC595s using the STM32F031K6 SPI peripheral.

Specifically, the Nucleo32 F031K6 boards plugged into the Edubase-V2 via the adapter used at Tennessee Tech.

Supports only the four seven-segment displays (DISP1-DISP4) on the EduBase-V2 board

 #include "mbed.h"
 #include "TTU_CSC1300.h"
 
 SSLED     seg7(4, ~0x00);    // blank DISP4 on Edubase-V2 board
 
 int main() {
     while(1) {
         seg7.setDisplay( 1, ~0x3F);      // display "0"
         wait(1.0);
         seg7.setDisplay( 2, ~0x06);      // display "1"
         wait(1.0);
         seg7.setDisplay( 3, ~0x5B);      // display "2"
         wait(1.0);
         seg7.setDisplay( 4, ~0x4F);      // display "3"
         wait(1.0);
     } // end while()
 } // end main()

Member Function Documentation

void setDisplay ( int  display,
int  pattern 
)

Write a pattern to a chosen display.

Parameters:
displayinteger (1-4) selected desired 7-segment display DISP1-DISP4
patternbyte containing bitmask of to display (zeroed bits illuminate)
Note:
MSb in pattern is decimal point segment, then gfedcba (with segment a as LSb). Zeroes in the pattern bitmask are illuminated. For example, pattern ~0x66 will illuminate the number "4".
