#include <SakuraIO.h>

//SakuraIO_SPI sakuraio(10);
SakuraIO_I2C sakuraio;
uint32_t cnt;

void setup(){
  cnt = 0;
  while((sakuraio.getConnectionStatus() & 0x80) != 0x80){
    delay(1000);
  }
}

void loop() {
  cnt++;
  sakuraio.enqueueTx(0,cnt);
  sakuraio.enqueueTx(1,cnt);
  sakuraio.enqueueTx(2,cnt);
  sakuraio.send();
  delay(1000);
}

Examples

Please see example code.

• Standard
• File download
• Firmware update
• Send temperature and humidity (HDC1000) (depends on hotchpotch/Arduino-HDC1000)
• Send temperature and humidity (BME280) (depends on sparkfun/SparkFun_BME280_Arduino_Library)
• 6-Axis
• Send human presence
• Shell
• Send illminance (CdS)

Notes

• On the Uno and other ATMEGA based boards, Values ​​of type double are sent as float type. (Please see Arduino Reference.)

• Please use SakuraIOUtils::double2float() when you want to handle the value of double type received as float. DO NOT USE C type casting. (Please see the example)
