I am using tsc2007 on linux.
The linux kernel has the following configuration to use tsc2007.


Required properties:
- compatible: must be "ti,tsc2007".
- reg: I2C address of the chip.
- ti,x-plate-ohms: X-plate resistance in ohms.
        tsc2007@49 {
            compatible = "ti,tsc2007";
            reg = <0x49>;
            interrupt-parent = <&gpio4>;
            interrupts = <0x0 0x8>;
            gpios = <&gpio4 0 0>;
            ti,x-plate-ohms = <180>;

What does x-plate-ohms mean?
Is the value dependent on the hardware?
How should x-plate-ohms be measured?

  • \$\begingroup\$ With a dmm that measures resistance. \$\endgroup\$ – Solar Mike Feb 1 '18 at 7:17
  • \$\begingroup\$ @SolarMike I have a dmm. But I do not know what x-plate-ohms is. \$\endgroup\$ – DonBit Feb 1 '18 at 7:27
  • \$\begingroup\$ You do show the answer "- ti,x-plate-ohms: X-plate resistance in ohms." ie the resistance of the plate for the x-direction in ohms. \$\endgroup\$ – Solar Mike Feb 1 '18 at 7:28
