    When there are multiple MAX7219s cascaded -- let's say 4 -- every SHIFTOUT command requires that many arguments in the command, with No-Ops sent to the...
  3. HW-179 8-Digit 7-Segment LED Display (Cascaded MAX7219s)

    My earlier post provided sample code for a single HW-179 8-digit 7-segment LED display. The MAX7219 provides for a cascade configuration such that multiples of 8-digit displays can be connected to...
  4. HW-179 8-Digit 7-Segment LED Display (MAX7219 Driver)

    This sample code demonstrates writing to an 8-digit 7-segment LED display (the HW-179 module) that uses the MAX7219 driver device. The MAX7219 is fully SPI compliant, and as such does not require...

  7. Re: Here is example code - PIC12F683 4-dig 7-Segment display - driven by TM1637

    Probably no functional advantages, but the 4-digit 7-segment TM1637 displays are dirt cheap. I have found them for about $1 on ebay from China. I used them in a small engine RPM indictor, and they...
  8. Re: Warning 202 Argument out of range. Least significant bits used

    Re: Winstar OLED Display Problem with lcdout comands

    Employing undocumented commands with a "WS0010 equivalent" controller would cause me many sleepless nights. I've learned to stay well within the boundaries of product specification sheets.
