IsegEncodeDigit() converts one digit to segment data.

uint8_t IsegEncodeDigit(uint8_t digit)

uint8_t data[4] = {
  IsegEncodeDigit(1),
  IsegEncodeDigit(2),
  IsegEncodeDigit(3),
  0x3E                    // V: F,E,D,C,B
};
 
IsegWrite(data);

• These commands are only for 4-digit FND displays with a TM1637 IC. They do not directly drive a generic multiplexed FND display.
• Use display commands after successfully calling IsegBegin().
• Initialization fails if CLK and DIO use the same pin, or if the device number is 7 or higher.
• length + position must be 4 or less. Numbers outside the range are not displayed, and false is returned.
• Communication may block execution for several ms. Do not call this from an interrupt service routine.
• Do not use the specified pins simultaneously for UART, PWM, encoders, external interrupts or other functions.
• Check the actual module and product manuals for FND power and signal voltages.
