Is possible unattach a pin joined a pwd? 

pwm27=pio.GPIO27
ledrojo = pwm.attach(pwm27, 10000, 0.2)
ledrojo:start()

i tryed whit ledrojo:stop() but the GPIO27 still is joined to pwm0

@pocampov, thanks for report this,

This feature is available since commit https://github.com/whitecatboard/Lua-RTOS-ESP32/commit/a1c8c8654de5f253c4a790122bcae21898df43fc.

In your case, for detach the pin:

ledrojo = nil

or

ledrojo:detach()

Thanks you for your help. I tried this in html page:


<?lua
pin26=pio.GPIO26
pwm27 = pio.GPIO27
pio.pin.setdir(pio.OUTPUT,pin26)
pio.pin.setpull(pio.NOPULL,pin26)
if ledrojo ~=nil then ledrojo:detach() end
ledrojo = pwm.attach(pwm27, 10000, 0.2)
ledrojo:start()          
?>

The first time it works well

But when I reload the page I get this error: /prueba.luap:11: gpio27 is used by pwm0

Have you upgraded to last commit? In my board, with last commit your example works as expected.
