My First LED

The first assignment of many for my CS10 (Introduction to Computer Science) Honors Project.

Using an ARM Chip, I deployed my code from https://os.mbed.com/.

Spring 2017

Sample Code:

#include "mbed.h"

Serial pc(USBTX, USBRX);

DigitalOut myled(LED1);

I2C i2c(D7, D8); const int addr = 0x50;

int main() { char data[3]; char cmd[3];

int d;

cmd[0] = 0;// read chip_id i2c.write(addr, cmd, 1); i2c.read(addr, data, 1); pc.printf("chip_id %02x", data[0] );

// OPR_MODE to IMU : 8 Reg. : 3D cmd[0] = 0x3D;// OPR_MODE Reg cmd[1] = 8; //IMU mode i2c.write(addr, cmd, 2);

while(1) { cmd[0] = 0x1E; // read euler pitch i2c.write(addr, cmd, 1);

i2c.read(addr, data, 2);

d = data[1] << 8 + data[0];

pc.printf("Euler Pitch %d\r\n", d );

myled = 1; // LED is ON wait(0.1); // 200 ms myled = 0; // LED is OFF wait(0.1); // 1 sec } }
