Howto configure the Linux kernel / drivers / w1


Dallas's 1-wire bus[]

  • Option: W1
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) Dallas's 1-wire support
      Dallas's 1-wire bus is useful to connect slow 1-pin devices such as iButtons and thermal sensors.
      If you want W1 support, you should say Y here.
      This W1 support can also be built as a module. If so, the module will be called wire.ko.


  • Option: W1_MATROX
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) Matrox G400 transport layer for 1-wire
    • depends on W1 && PCI
      Say Y here if you want to communicate with your 1-wire devices using Matrox's G400 GPIO pins.
      This support is also available as a module. If so, the module will be called matrox_w1.ko.


  • Option: W1_DS9490
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) DS9490R transport layer driver
    • depends on W1 && USB
      Say Y here if you want to have a driver for DS9490R UWB <-> W1 bridge.
      This support is also available as a module. If so, the module will be called ds9490r.ko.


  • Option: W1_DS9490_BRIDGE
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) DS9490R USB <-> W1 transport layer for 1-wire
    • depends on W1_DS9490
      Say Y here if you want to communicate with your 1-wire devices using DS9490R USB bridge.
      This support is also available as a module. If so, the module will be called ds_w1_bridge.ko.


  • Option: W1_THERM
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) Thermal family implementation
    • depends on W1
      Say Y here if you want to connect 1-wire thermal sensors to you wire.


  • Option: W1_SMEM
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) Simple 64bit memory family implementation
    • depends on W1
      Say Y here if you want to connect 1-wire simple 64bit memory rom(ds2401/ds2411/ds1990*) to you wire.


  • Option: W1_DS2433
    • Kernel Versions: 2.6.15.6 ...
    • (on/off/module) 4kb EEPROM family support (DS2433)
    • depends on W1
      Say Y here if you want to use a 1-wire 4kb EEPROM family device (DS2433).


  • Option: W1_DS2433_CRC
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Protect DS2433 data with a CRC16
    • depends on W1_DS2433
    • select CRC16
      Say Y here to protect DS2433 data with a CRC16. Each block has 30 bytes of data and a two byte CRC16. Full block writes are only allowed if the CRC is valid.
