pwm-exp i2c addres[RESOLVED]

Ruslan Baryshnikov247

I need to change i2c addres for pwm-exp. Default addres 0x5a. My device's addres is 0x40.
I clone i2c-exp-driver from Github.
In file i2c-exp-driver/include/pwm-exp.h I change define PWM_I2C_DEVICE_ADDR from 0x5a to 0x40.
And make project.
From i2c-exp-driver/bin I move pwm-exp file to /usr/sbin.
I start pwm-exp in verbose mode:

# pwm-exp -v -i
> Initializing PWM Expansion chip
> Generating PWM signal with 0.00% duty cycle (0.00% delay)
onion-i2c:: Writing to device 0x5a: addr = 0xfa, data = 0x00 (data size: 1)
onion-i2c:: Writing to device 0x5a: addr = 0xfb, data = 0x00 (data size: 1)
onion-i2c:: Writing to device 0x5a: addr = 0xfc, data = 0x00 (data size: 1)
onion-i2c:: Writing to device 0x5a: addr = 0xfd, data = 0x10 (data size: 1)
onion-i2c:: Writing to device 0x5a: addr = 0x01, data = 0x04 (data size: 1)
onion-i2c:: Writing to device 0x5a: addr = 0x00, data = 0x01 (data size: 1)
onion-i2c:: Reading 1 byte from device 0x5a: addr = 0x00        read 1 byte, value: 0xff
onion-i2c:: Writing to device 0x5a: addr = 0x00, data = 0xef (data size: 1)
onion-i2c:: Reading 1 byte from device 0x5a: addr = 0x00        read 1 byte, value: 0xff
onion-i2c:: Writing to device 0x5a: addr = 0x00, data = 0xff (data size: 1)

Why addres not changed? Why addres is 0x5a???
I delete old pwm-exp file from /usr/sbin and write new file. It is not work.

I know.
I copy and change file libonionpwmexp.so from i2c-exp-driver/lib to /usr/lib/.
And dont forget reboot.
