| frank26080115 | 0:bf7b9fba3924 | 20 | @Example description: |
| frank26080115 | 0:bf7b9fba3924 | 21 | Purpose: |
| frank26080115 | 0:bf7b9fba3924 | 22 | This example describes how to test Motor Control PWM module in LPC17xx. |
| frank26080115 | 0:bf7b9fba3924 | 23 | Process: |
| frank26080115 | 0:bf7b9fba3924 | 24 | Tested function on MCPWM could be: |
| frank26080115 | 0:bf7b9fba3924 | 25 | - 3-phase AC mode: inverted output is enable, A0 and A1 output pin is internally routed to A0 signal |
| frank26080115 | 0:bf7b9fba3924 | 26 | - 3-phase DC mode: inverted output is enable |
| frank26080115 | 0:bf7b9fba3924 | 27 | - capture on Motor Control: in this case is used to detect the falling edge on MCO0B output pin. |
| frank26080115 | 0:bf7b9fba3924 | 28 | The MCFB0 input pin therefore must be connected to MCO0B. |
| frank26080115 | 0:bf7b9fba3924 | 29 | + Capture Channel 0. |
| frank26080115 | 0:bf7b9fba3924 | 30 | + Capture falling edge on MCFB0 input pin. |
| frank26080115 | 0:bf7b9fba3924 | 31 | + Interrupt enabled on capture event. |
| frank26080115 | 0:bf7b9fba3924 | 32 | |
| frank26080115 | 0:bf7b9fba3924 | 33 | Channel 0,1,2 will be configured as follows: |
| frank26080115 | 0:bf7b9fba3924 | 34 | - edge aligned operation |
| frank26080115 | 0:bf7b9fba3924 | 35 | - polarity pin: Passive state is LOW, active state is HIGH |
| frank26080115 | 0:bf7b9fba3924 | 36 | - disable dead time |
| frank26080115 | 0:bf7b9fba3924 | 37 | - enable update value |
| frank26080115 | 0:bf7b9fba3924 | 38 | - period time = 300 |
| frank26080115 | 0:bf7b9fba3924 | 39 | - pulse width value: |
| frank26080115 | 0:bf7b9fba3924 | 40 | + channel 0 = 0 |
| frank26080115 | 0:bf7b9fba3924 | 41 | + channel 1 = 100 |
| frank26080115 | 0:bf7b9fba3924 | 42 | + channel 2 = 200 |
| frank26080115 | 0:bf7b9fba3924 | 43 | The program will update the value for pulse width for 3 channel continuously from 0 to 300, increase 20 |
| frank26080115 | 0:bf7b9fba3924 | 44 | each update time. After each update, the serial will write "Update!" into screen. |
| frank26080115 | 0:bf7b9fba3924 | 45 | After that, 'CapFlag' will be checked if detect falling edge on MCO0B or not. |
| frank26080115 | 0:bf7b9fba3924 | 46 | If yes, the program will print the current capture value into screen. |
