Android VIM3L
Which version of system do you use? Please provide the version of the system here:
Pie9-64
please help me with the task.
I need to read the temperature of the SoC once a minute and, depending on it, generate a PWM on the GPIO35.
This is the only way to transfer it to a third-party application… I don’t understand how to do this.
then input command as follow
echo 1 > /sys/class/pwm/pwmchip4/export
echo 1000000 > /sys/class/pwm/pwmchip4/pwm1/period
echo 500000 > /sys/class/pwm/pwmchip4/pwm1/duty_cycle
echo 1 > /sys/class/pwm/pwmchip4/pwm1/enable
you will see the pwm input by oscilloscope
BUT… I don’t see “arch/arm/boot/dts/amlogic/kvim3.dts”, also I don’t see “pwm1”
