IsegBegin()

IsegBegin() sets the CLK/DIO pins and device number of a TM1637 FND display.

bool IsegBegin(uint8_t clkPin, uint8_t dioPin, uint16_t bitDelayUs = 100, uint8_t device = 0)

Commands

Command	Arguments	Return Value	Operation
`IsegBegin(clkPin, dioPin, bitDelayUs, device)`	`uint8_t clkPin` — Arduino pin number connected to FND CLK `uint8_t dioPin` — Arduino pin number connected to FND DIO `uint16_t bitDelayUs = 100` — TM1637 bit communication delay (µs), default `100` `uint8_t device = 0` — FND device number `0~6`, defaults to `0`	`bool`	Sets the CLK/DIO pins and device number of a TM1637 FND display.

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.
