POWER_LED not blink

[nopnop2002]

My code is below. STATUS_LED flashes on and off. but POWER_LED don't flashes on and off.

-- coding: utf-8 -- from pyA20.gpio import gpio from pyA20.gpio import port from pyA20.gpio import connector import time

COUNT = 3 PIN1 = port.POWER_LED PIN2 = port.STATUS_LED

PIN1 = connector.LEDp1 # This is the same as port.POWER_LED

PIN2 = connector.LEDp2 # This is the same as port.STATUS_LED

gpio.init() gpio.setcfg(PIN1, gpio.OUTPUT) gpio.setcfg(PIN2, gpio.OUTPUT)

for _ in xrange(COUNT): gpio.output(PIN1,True) gpio.output(PIN2,True) time.sleep(1.0) gpio.output(PIN1,False) gpio.output(PIN2,False) time.sleep(1.0)

Sorry my Poor English.

try this example in orangepi_PC_gpio_pyH3\examples\blink_POWER_STATUS_PL10.py

I remeber I has tested this code，it work

Thank you very much for your answer.

I tried orangepi_PC_gpio_pyH3\examples\blink_POWER_STATUS_PL10.py with my OrangePi-PC. It can't blink POWER_LED(Yellow LED). So i tried these command. It's work fine. I can blink POWER_LED(Yellow LED).

standby_led is linked with PL10. I think your cord is right,but it can't blink POWER_LED(Yellow LED).

Thank you very much for your useful library.

I knew the cause. Registers begin at 0x01C20800.

Port L have a different address. Registers for port L begin at 0x01F02C00.
