This week’s assignments

write an application that interfaces with an input &/or output device

A very simple board is created with msp430g2553 and programed with Energia.

Mini USB connector is for power only.

Jumper wires from TI Launchpad

The board is connect to a bluetooth module (HC-05) via serial port.

An android app was created to receive data via bluetooth and plot them in real time. (This app is created as a favour to my friend, thus the interface is in chinese.)

Code

#define A_INPUT A6
#define D_INPUT P1_6

int adc;
int index=0;

void setup()
{
  Serial.begin(9600);
}
void loop()
{
  adc=analogRead(A_INPUT);
  Serial.write('1\t');
  Serial.write(index);
  Serial.write('\t');
  Serial.write(adc);
  Serial.write('\n');
  index++;
  delay(100);
}
