PiBox » libpibox

Here is what the API should look like:

• rpiInit(path) - load and parse the file into a list of name/value pairs. Returns 0 on success, 1 on failure. Does not validate existing names.
• rpiSet(name, value) - Update the specified name with the specified value. If name does not exist, add it if its a valid name. Returns 0 on succes, 1 on failure (not a valid name).
• rpiNames() - returns a list of supported names. This will not be the complete set of configuration options available to config.txt. It is only what is supported by the API.
• rpiValues(name) - returns a list of support values for the specified name. Returns null if the name is not valid.
• rpiGetValue(name) - returns the current value for the specified name
• rpiSave(path) - save current configuration. Does not validate configuration when writing.

The initial set of valid names that will be supported are:

• Overscan
  • disable_overscan
  • overscan_left
  • overscan_right
  • overscan_top
  • overscan_bottom
• HDMI
  • hdmi_safe
  • hdmi_drive
  • hdmi_mode
• decode_MPG2 (licensed code for MPEG-2 decoding)
• display_rotate
• Overclock
  • arm_freq - setting this automatically sets the others
  • core_freq
  • sdram_freq
  • over_voltage
• Memory
  • gpu_mem_256 or gpu_mem_512

These values are preset to these values if not found in the config file.

• hdmi_ignore_edid_audio=1
• disable_splash=1
• dtparam=act_led_trigger=heartbeat (instead of mmc, so I can see processor load)
