Welcome to the Phoenix GPADC wiki.
[edit] Introduction
This wikipage describes the Phoenix GPADC software development efforts for OMAP4 platform. The purpose is to provide information on the current status and features planned in the road map.
[edit] List of Features Supported
- On OMAP4
- GPADC Command Interface for command/ control of the GPADC functionality
- GPADC Conversion Mechanism for triggering GPADC conversion
- GPADC Reading Mechanism for reading the GPADC values generated by Phoenix via the I2C bus
- GPADC support for RT and SW interrupt mode for conversion
[edit] Design
- Interface
- The OMAP443x GPADC drivers interface with user space applications through ioctl calls
- Other kernel modules can interface through exported function call
- GPADC Driver
- This interfaces with GPADC module in Phoenix chip via i2c lines
- Once the digitally converted parameters are available, GPADC module interrupts MPU through INT interrupt line
