joinamruta 0:ca76ec016be0 2 * Program to implement a microwave. A RTOS program to simulate a microwave *
joinamruta 0:ca76ec016be0 3 * which has the following user features: *
joinamruta 0:ca76ec016be0 4 * i) Left and right buttons to raise/lower the cook time in 1 minute increments *
joinamruta 0:ca76ec016be0 5 * ii) Top and bottom buttons to start/stop the microwave *
joinamruta 0:ca76ec016be0 6 * iii) Middle button to open/close the door *
joinamruta 0:ca76ec016be0 7 * iv) Temperature sensor to show the inside temperature *
joinamruta 0:ca76ec016be0 8 * v) LCD output to show: *
joinamruta 0:ca76ec016be0 9 * (1) Requested cook time *
joinamruta 0:ca76ec016be0 10 * (2) Elapsed cook time (max 3 minutes) *
joinamruta 0:ca76ec016be0 11 * (3) Temperature (goes up each minute by 10(?) degrees, starting with room) *
joinamruta 0:ca76ec016be0 12 * vi) LED to show: *
joinamruta 0:ca76ec016be0 13 * (1) One LED blinking to show cooking in progress *
joinamruta 0:ca76ec016be0 14 * vii) Short audio sound: *
joinamruta 0:ca76ec016be0 15 * (1) To indicate cooking done *
joinamruta 0:ca76ec016be0 16 * Timing requirements: *
joinamruta 0:ca76ec016be0 17 * 1. Cooking must stop within 1ms of door opening or stop button *
joinamruta 0:ca76ec016be0 18 * 2. Temperature sensor must be polled once every 10 seconds *
joinamruta 0:ca76ec016be0 19 * 3. Cooking time must have a 3 min max with a default of 2 min *
joinamruta 0:ca76ec016be0 20 * *
joinamruta 0:ca76ec016be0 21 * Test cases: *
joinamruta 0:ca76ec016be0 22 * The following test cases are done using black box approach. If DEBUG is *
joinamruta 0:ca76ec016be0 23 * enabled, some white box testing can be performed *
joinamruta 0:ca76ec016be0 24 * *
joinamruta 0:ca76ec016be0 25 * Test conditon Pass/Fail criteria Pass/Fail *
