STMicroelectronics STM32 Timer quadrature encoder
|
|
|
|
STM32 Timer provides quadrature encoder to detect
|
|
angular position and direction of rotary elements,
|
|
from IN1 and IN2 input signals.
|
|
|
|
Must be a sub-node of an STM32 Timer device tree node.
|
|
See ../mfd/stm32-timers.txt for details about the parent node.
|
|
|
|
Required properties:
|
|
- compatible: Must be "st,stm32-timer-counter".
|
|
- pinctrl-names: Set to "default".
|
|
- pinctrl-0: List of phandles pointing to pin configuration nodes,
|
|
to set CH1/CH2 pins in mode of operation for STM32
|
|
Timer input on external pin.
|
|
|
|
Example:
|
|
timers@40010000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
compatible = "st,stm32-timers";
|
|
reg = <0x40010000 0x400>;
|
|
clocks = <&rcc 0 160>;
|
|
clock-names = "int";
|
|
|
|
counter {
|
|
compatible = "st,stm32-timer-counter";
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&tim1_in_pins>;
|
|
};
|
|
};
