# MCPWM basic config Example
|
||
|
|
|
||
|
|
This example will show you how to use each submodule of MCPWM unit
|
||
|
|
|
||
|
|
The example can't be used without modifying the code first
|
||
|
|
|
||
|
|
Edit the macros at the top of mcpwm_example_basic_config.c to enable/disable the submodules which are used in the example
|
||
|
|
|
||
|
|
|
||
|
|
## Step 1: Pin assignment
|
||
|
|
* The gpio init function initializes:
|
||
|
|
* six MCPWM output pins
|
||
|
|
* three MCPWM fault input pins
|
||
|
|
* three MCPWM sync input pins
|
||
|
|
* three MCPWM capture input pins
|
||
|
|
|
||
|
|
|
||
|
|
## Step 2: Connection
|
||
|
|
* Six MCPWM output pins to motor driver input signals
|
||
|
|
* Fault, sync, capture signals can be connected to respective signals
|
||
|
|
|
||
|
|
|
||
|
|
## Step 3: Initialize MCPWM
|
||
|
|
* You need to set the frequency and duty cycle of each three MCPWM timer along with other parameters mentioned
|
||
|
|
* You need to set the MCPWM channel you want to use, with these timers
|
||
|
|
|
||
|
|
|
||
|
|
## Step 4: Testing
|
||
|
|
* The deadtime module, set deadtime type and with value as time*100ns
|
||
|
|
* The sync module, synchonizes all the timer pulses
|
||
|
|
* The fault module when enabled takes action on MCPWM signals when fault occurs
|
||
|
|
* The capture module captures input signal(digital i.e. hall sensor value, etc), timing between two rising/falling edge
