Error writing Serial Data, public command "write" not accessible within my defined function

#include "mbed.h"
#include <stdint.h>

enum State
{
	off,
	on
};

void Sample();
Serial COM(PTD3, PTD2); // serial object to communicate with the other k22f
Ticker Sample_func; // timer object
DigitalOut Flash(PTD4); // Pin PTD4 will output 3.3V
State state = on;
AnalogIn ADC_PIN(PTB0);  // analogue pin
PwmOut PWM_Brightness(PTC3); // LED pin

float ADC_value = 0;
float Temp = 0;


int main()
{
	Flash = state; // put power on
	PWM_Brightness.period(0.0005);
	COM.baud(57600); COM.format(8, SerialBase::None, 1); // setting COM paramters
	Sample_func.attach(Sample, 0.1);

	while (true)
		;
}
	
void Sample()
{
	ADC_value = ADC_PIN.read();
	uint8_t Send = (int)(255 * ADC_value);
	
	if (((int)(100 * ADC_value)) != ((int)(100 * Temp)))
	{
		COM.write(&Send,1); // send data
	}

	PWM_Brightness.write(ADC_value);

	Temp = ADC_value;
}

Please use the <<code>> and <</code>> tags around your poster code to keep it readable. The write methods are part of the new asynchronous operations which are currently only supported by the Silicon Labs platforms. Unfortunately that fact is very badly documented. You should replace it with your own call to number of putc () operations.
