Diese Software ermöglicht es die Funktionen des Audio/Video Umschaltchip unter Linux zu nutzen.

Softwarevoraussetztungen

• lm-sensors wird benötigt
• in der Activy müssen folgende Module geladen sein
  • i2c-core
  • i2c-dev
  • i2c-i801

Wie benutzen

- Option '-i': Number of i2c-adapter (default:0) - Option '-a': Address of tdk5002c (default: 0x48) - Option '-d': If given, prints out only the read-register info. - Option '-s': Use a predefined register-sequence 0: switch AUX-Scart to Tv-Out/Console 1: switch AUX-Scart to loopthru from TV-Scart 2: switch AUX-Scart to em8400 output (a+v)

- Writing the register one by one: You have to give the complete values (20)

 for the write registers (0-4), one after the other - you have to write them
 in Hex-Format.
 Sample:
 "MYSUPERPC> ./tdk5002cctl 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02"
 
 The parameters are in the same order as in the write registers of the
 TDK, order is from register 0-4, within register it's from LSB to MSB.
 
 You don't have to give an offset to a single parameter, e.g. if you want
 to turn on "TV RGB Mute" (Bit 6 in Register 1), just give a "0x01" - or a
 "0x00" if you want to turn it off.  

Beispiele

• ./tdk5002cctl -i 1 -a 0x50 -d

Gibt nur die read-registers für chip 0x50 am i2c-adapter 1

• ./tdk5002cctl -s 2

Schaltet AUX-Scart der Activy zum em8400 output

• ./tdk5002cctl -i 2 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02 0x03 0x01 0x02

setzt alle parameter für tdx am i2c-adapter 2
