- Revision:
- 20:4951ea6abee5
- Parent:
- 17:af1f2416dd26
The following changes were made:
1.) Modified udelay() function for generating more accurate smaller usec delays
2.) Implemented the irq_enable and irq_disable functions
3.) Removed the confusion b/w application created peripheral object and interrupt specific object
4.) Created PWM extra init structure and added PWM pin
5.) Added a module for timer and its related header file
