![]() ![]() My next project is to add an existing rain sensor, where existing means its hardware is there and working but the software is outdated and/or not working anymore. ![]() But mailing as well as acessing the internet and my raspberries works fine, too. Let me add that I'm curently using ESP-01 (with the soldering deep sleep mod), ESP-12 as well as Wemos D1 Mini mostly for checking the environment. Maybe you - or another nice person reading my question - find the time to help me in my area where I'm stuck. You seem to be the guy with a really big knowhow in the esp topic. Not to forget the also funny ones on youtube. Because we can declare more than one pin, we have to define a so called “mask” instead of only a pin.ĭear Andreas, Thank you so much for your informative posts. In this mode, we can use several pins for wake-up. I used a 100k resistor and it worked.īut what, if we would like to have several buttons for the wake-up? Also here, our new toy offers an elegant solution: we use the ext1 wake-up source. One thing is important: You have, depending on the interrupt polarity, to connect an external pull-up or down resistor to the pin. Fortunately, we still have our Excel sheet and we can see, that RTC_GPIO00 and GPIO36 are connected to the same pin on the WROOM-32 module. ![]() To find-out the pin number is a little tricky: We have to use the GPIO number of the pin, not the RTC_GPIO pin number. And in addition, we can decide, if we want to trigger the wake-up by a low or a high state of the pin. To do this, we have to select the ext0 mode and tell the chip, which pin is connected to the button. Here, we get much more possibilities: We can wake-up the chip by one particular pin only. This was also possible with the ESP8266 by resetting the chip. The next is wake-up by an external source. ![]()
