@ajb2k3 This is the one I have: https://docs.m5stack.com/en/module/goplus2

@ajb2k3 Tested all 4 ports, no PWM signal on any of them. All of them have 5V power.

@felmue I have the servo in the port with a small 2, the LED between the servos is green, I've measured 5V between G and V but when I connect a oscilloscope beween S and G there's no trace of PWM.

I'm using GoPlus2 (big label on the side) and program is very simple:

MD5 is as follows (can't attach)

I have both, but when I connect a servo to the GoPlus2 it doesn't move at all.

I have flashed Core2 firmware and I'm using Flow to do it.

Very simple program with a loop for moving the servo, full stop.

I've measured header voltages and there's 5V to GND.
Oscilloscope at "S" shows no PWM and even no pulses at all. S keeps at 0v always and therefore servo doesn't move.

I've run out of ideas...

@ajb2k3 I wasn't aware of ultrasonic I2C!
Wonderful!!!

Here I've only been able to find GPIO ones

Thank you veyr much for clarification

PaHub is I2C but I'm afraid that ultrasonic units with trig and echo are not I2C so won't work with PaHub

For a quick comparison, here it is when power is on:

Hello,

I thought that ePaper kept the last drawing despite power off.

My screen ink starts to fade away and gets dim grey in less than 3 seconds after I press the reset button. Is it the expected behavior or I have a faulty unit?

Thanks!

I have an Atom Switch D unit and I can't select it so that I have blocks for the relays

It's very nice to design UIs with UIFlow

The problem comes if I want to use different "pages", say a main menu and several sub menus.

I think UIFlow needs to handle the "page" concept and be able to select which page is shown from the code

Perhaps each page should run it's own blocks and have a "background" page for all the other code.

What do you think?
