IsegDecimal()

IsegDecimal() displays an integer in decimal format.

bool IsegDecimal(int32_t number, bool leadingZero = false, uint8_t dotPosition = 0, uint8_t length = 4, uint8_t position = 0, uint8_t device = 0)

Commands

Command	Arguments	Return Value	Operation
`IsegDecimal(number, leadingZero, dotPosition, length, position, device)`	`int32_t number` — Decimal or hexadecimal value to display `bool leadingZero = false` — `true`: leading zeros, `false`: leading spaces `uint8_t dotPosition = 0` — Decimal point position. `0` means none; `1~length` selects the digit from the left `uint8_t length = 4` — Number of digits to write `1~4` `uint8_t position = 0` — Start position `0~3`; the leftmost digit is `0` `uint8_t device = 0` — FND device number `0~6`, defaults to `0`	`bool`	Displays an integer in decimal format.

Example

void setup() {
  IsegBegin(14, 15, 100, 0);  // Set the CLK/DIO pins and device number of the TM1637 FND.
  IsegBegin(130, 131, 100, 1);  // MPAINO K/K2 GPIO channels 0, 1
  IsegBrightness(7, true, 0);  // Set display brightness and on/off state.
  IsegBrightness(4, true, 1);  // Set display brightness and on/off state.
}
 
void loop() {
  IsegDecimal(1234, false, 0, 4, 0, 0);  // Display an integer in decimal format.
  IsegHex(0xABCD, false, 0, 4, 0, 1);  // Display an integer in hexadecimal format.
}

Precautions

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.
