PWMRANGE error

[DziveQ]

Hi. I'm trying to use example simple_led and the only thing I changed was SSID name and password. When I'm uploading, I'm getting this error:

C:\Users\kacpe\AppData\Local\Temp\arduino_modified_sketch_215244\simple_led_accessory.c: In function 'led_update':
simple_led_accessory.c:67:13: error: 'PWMRANGE' undeclared (first use in this function)
67 | int pwm = PWMRANGE - (int) (led_bri * 1.0 * PWMRANGE / 100.0 + 0.5f);
| ^~~~~~~~

exit status 1
'PWMRANGE' undeclared (first use in this function)

I'm using correct Port and Board settings (it's working with other sketches)

Guys, I have the same problem.
Googling for the PWMRANGE variable gave me the following issue:

1.) the change of PWMRANGE via analogWriteRange(new_range) is not possible!
-> if you set 1000 or 255 for example there ist no change -> only 1023.

This issue has nothing to do with this project. However, I decided to try redefining the PWMRANGE variable.
I just added a declaration int PWMRANGE = 1023; to the method led_update()

void led_update() {
	if (led_power) {
		int PWMRANGE = 1023;     // redefining PWMRANGE here
		int pwm = PWMRANGE - (int) (led_bri * 1.0 * PWMRANGE / 100.0 + 0.5f);
		analogWrite(PIN_LED, pwm);
		printf("ON  %3d (pwm: %4d of %d)\n", led_bri, pwm, PWMRANGE);
	} else {
		printf("OFF\n");
		digitalWrite(PIN_LED, HIGH);
	}
}

This is a very dirty solution. But it allowed me to compile the example.

Con esta corrección me ha funcionado, el problema es que al poner el 100% de brillo se apaga, y al poner 0% se enciende del todo, alguien sabe algo? en definitiva funciona del revés

Lecturas monitor serie:
(en este estado la barrita esta la luz al 100% de brillo, pero se apaga del todo)
ON 100 (pwm: 0 of 1023)

(en este estado la barrita esta la luz al 0% de brillo, pero se enciende del todo)
ON 0 (pwm: 1023 of 1023)
OFF

This is due to an old reference, for the esp8266 library that was since updated.
#define PWMRANGE 1023 was removed
esp8266/Arduino#7456

In the default library this was set to the upstream value of 255:
