Multiple decimal points

[cs-spacecat]

I have looked everywhere but found no solution, so I'm asking here.

How would i go about lighting up multiple decimal points at once without resorting to sevseg.setSegments?

Thanks in advance!

For sure the focus is on presenting numbers. It would be handy to also display various states using a DP however, it quickly becomes apparent there are many different seven segment displays. I'm going to assume your DPs are managed on segment h of a digit.

Make the SevSeg library literal files in your project and consider the following edit to setDigitCodes for multi-DPs. Works for me.

// setDigitCodes
/******************************************************************************/
// Sets the 'digitCodes' that are required to display the input numbers
// Use 
// * positive decPlaces to denote decimal precision
// * -1 (the default) no decimal places
// * and less than -1 value to allow for multiple DPs (segment h). Supports upto 7 DPs
//   must set msb=1 and other bits according to digitNum as natural numbers from lsb to msb
// for example:
// setNumber(numToShow, 0b10001010); // DPs on digit 4 and digit 2

void SevSeg::setDigitCodes(const uint8_t digits[], int8_t decPlaces) {

  // Set the digitCode for each digit in the display
  for (uint8_t digitNum = 0 ; digitNum < numDigits ; digitNum++) {
    digitCodes[digitNum] = digitCodeMap[digits[digitNum]];
    // Set the decimal point segment
    if (decPlaces >= 0) {
      if (digitNum == numDigits - 1 - decPlaces) {
        digitCodes[digitNum] |= digitCodeMap[PERIOD_IDX];
      }
    // Set the DPs in their place
    } else if (decPlaces < -1 || digitNum < 7) {
      if (bitRead(decPlaces, digitNum)) {
        digitCodes[digitNum] |= digitCodeMap[PERIOD_IDX];
      }
    }
  }
}
