Does anybody happen to have a Capacitive touch screen using
the edt_ft5x06 driver hooked up to a bone ?
If anybody does can you send me the output of "i2cdump 1 0x38"
I have a buydisplay.com tft with cap touch.
it uses a ft5x06 controller
It may be that the current driver built into the kernel will not
function with a non etd touch panel
Its all hooked up correctly I see the device @ 0x38 I think i have the
overlay correct it looks like
all other overlays when it comes to this type of touch panel
i see nothing using these commands related to a display
dmesg | grep i2c
dmesg | grep input
I can see the IRQ pin go low when i press on the display
I dont see any interrupts assigned although i asked for one in the overlay
section in fragment@0 of overlay
edt_ft5x06_pins: pinmux_edt_ft5x06_pins {
pinctrl-single,pins = <
BONE_P9_23 (PIN_INPUT_PULLUP |
MUX_MODE7) // interrupt for touch
>;
here is fragment 1 where touch is
fragment@1 {
target = <&i2c1>;
__overlay__ {
pinctrl-names = "default";
pinctrl-0 = <&bb_i2c1_pins>;
status = "okay";
clock-frequency = <400000>;
/* shut up DTC warnings */
#address-cells = <1>;
#size-cells = <0>;
// touch screen controller on ER-TFTM070-5
touch: edt-ft5x06@38 {
status = "okay";
compatible =
"edt,edt-ft5306","edt,edt-ft5406","edt,edt-ft5206","edt,edt-ft5x06";
pinctrl-names = "default";
pinctrl-0 = <&edt_ft5x06_pins>;
reg = <0x38>;
interrupt-parent = <&gpio1>; // gpio1_17
pin P9_23
interrupts = <0x17 0x0>;
//reset-gpios = <&gpio2 6 1>;
touchscreen-size-x = <800>;
touchscreen-size-y = <480>;
};
It all looks fine to me but i am at a loss as to why things are not
loaded or detected
IF anybody sees something obvious or knows anything about this please
help :)
