====== Digital IO - Test Case ======

===== Initial Setup =====

In order to proceed through the test case, first of all delete the Scopy *.ini file (saves previous settings made in Scopy tool) from the following path on Windows: C:\Users\your_username\AppData\Roaming\ADI .

Open the DigitalIO instrument. The interface should look like the picture below:

{{:university:tools:m2k:scopy:test-cases:digitalio_init.png?700|}}

Press multiple times on the "Run" button to check if the instrument works.

^ Description ^ Test Steps ^ Steps Resources ^ Expected Results ^ 
| Checking individual digital pin state | 1. Set DIO 0-7 and DIO 8-15 as individual pins | {{:university:tools:m2k:scopy:test-cases:dio-individual.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 2. Set channel 0 as output | {{:university:tools:m2k:scopy:test-cases:0out.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 3. Set channel 7 as input | {{:university:tools:m2k:scopy:test-cases:7in.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 4. Connect digital channel 0 to channel 7 via wires. |  {{:university:tools:m2k:scopy:test-cases:0-7pin_connection.png?100|}} |  |
| ::: | 5. Change the logic state of channel 0 (0/1) multiple times and monitor channel 7 state. | {{:university:tools:m2k:scopy:test-cases:high0-7.png?100|}} {{:university:tools:m2k:scopy:test-cases:low0-7.png?100|}} | When channel 0 is set to logic one, channel 7 will be automatically set to logic 1. When channel 0 is set to logic one, channel 7 will be automatically set to logic 1. |
| ::: | 6. Connect the channel 0 to voltmeter and channel 7 to the positive power supply. |  {{:university:tools:m2k:scopy:test-cases:0-ps_7-vm_pin_connection.png?100|}} |  |
| ::: | 7. Set channel 0 to logic state 0. | {{:university:tools:m2k:scopy:test-cases:low0.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 8. Monitor the voltage value via voltmeter. | {{:university:tools:m2k:scopy:test-cases:low-voltmeter.png?100|}} | On the voltmeter the voltage displayed is be between -0.050V and 0.4V. |
| ::: | 9. Set channel 0 to logic state 1. | {{:university:tools:m2k:scopy:test-cases:high0.png?100|}} | The interface should look like in the "Step Resources" picture (left side).  |
| ::: | 10. Monitor the voltage value via voltmeter. | {{:university:tools:m2k:scopy:test-cases:high-voltmeter.png?100|}} | On the voltmeter the voltage displayed should be between 2.9V and 3.4V. |
| ::: | 11. Set positive power supply to voltage level between 0V and 0.8V. | {{:university:tools:m2k:scopy:test-cases:ps-low.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 12. Monitor the channel 7 logic state. | {{:university:tools:m2k:scopy:test-cases:7low.png?100|}} | Channel 7 indicates logic 0 level. |
| ::: | 13. Set positive power supply to voltage level between 2V and 3.3V | {{:university:tools:m2k:scopy:test-cases:ps-high.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 14. Monitor the channel 7 logic state. | {{:university:tools:m2k:scopy:test-cases:7high.png?100|}}   | Channel 7 indicates logic 1 level. |
| ::: | 15. In step 2 replace by turn channel 0 with channels from 1 to 6 and from 8 to 15. Then, for each replacement repeat steps from 3 to 13.   |  |  | 
| ::: | 16. In step 2 replace with channel 7 and in step 3 by turn channels from 0 to 6 and from 8 to 15. Then, for each replacement repeat steps from 4 to 13. |  |  |

==== B. Group Operation ====
<hidden>
Set DIO 0-7 and DIO 8-15 groups as Group pins:


^ Description                           ^ Test Steps     ^ Steps Resources ^ Expected Results ^  
| Checking grouped digital pin states | 1. Set DIO 0-7 and DIO 8-15 as Group pins. | {{:university:tools:m2k:scopy:test-cases:dio-group.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 2. Connect DIO 0-7 to DIO 8-15 via wires. | {{:university:tools:m2k:scopy:test-cases:group-pinconnection.png?100|}} |  |
| ::: | 3. Set DIO 0-7 as output. | {{:university:tools:m2k:scopy:test-cases:dio07out.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 4. Set DIO 8-15 as input. | {{:university:tools:m2k:scopy:test-cases:dio815in.png?100|}} | The interface should look like in the "Step Resources" picture (left side). |
| ::: | 5. Set DIO 0-7 at value 0. | {{:university:tools:m2k:scopy:test-cases:grp-val0.png?100|}} | The same value of DIO 0-7 group must be displayed on the DIO 8-15 group. |
| ::: | 6. Set DIO 0-7 at value 128. | {{:university:tools:m2k:scopy:test-cases:grp-val128.png?100|}} | The same value of DIO 0-7 group must be displayed on the DIO 8-15 group. |
| ::: | 7. Set DIO 0-7 at value 170. | {{:university:tools:m2k:scopy:test-cases:grp-val170.png?100|}} | The same value of DIO 0-7 group must be displayed on the DIO 8-15 group. |
| ::: | 8. Set DIO 0-7 at value 255. | {{:university:tools:m2k:scopy:test-cases:grp-val255.png?100|}} | The same value of DIO 0-7 group must be displayed on the DIO 8-15 group. |
| ::: | 9. Set DIO 0-7 as input and DIO 8-15 as output. Repeat step 2. |  | For each value set for the DIO 8-15 group, the same value must be displayed on the DIO 0-7 group. |
