Nodemcu with espusb

[openscoreboard]

I have a nodemcu
I can flash espusb inside
I can connect my smartphone to 192.168.4.1
But i lost connection if push web buttons...

What schematic need for connect a nodemcu and work with espusb in mode hid?

Thank!!!

You need to flash the webpage.

Flash web/page.mpfs to 0x100000

Please see schematic info on this page: https://github.com/cnlohr/espusb

I try flash to 0x100000 but the connection from smartphone lost again....
I see schematic too, but my nodemcu is a little diferent...

I have connect a resistor(>=1K) between 3,3v and gpio4

Is It ok my connection?

Thanks...

[cnlohr]

What resistor are you using? 1.5k is nominal. Connection should be ok.

Do you have access to a Linux computer, using dmesg it can make it much easier to understand what's going on.

[openscoreboard]

I have a resistor with 1,2K

And this is the output dmesg

My steps

• Connect NODEMCU by USB to PC (linux)
• run commands make burn and make burnweb (my nodemcu blink the led)
  -Disconnect USB
  -Connect GPIO4+resistor+3v
  -Reconnect USB to PC
  -I think that no happend nothing

Thanks...

uuhhhh ... can you take a picture of your setup? I don't see where you're hooking the second USB in. Also, you should never need to unplug the NodeMCU usb. Just plug both USB plugs in.

[openscoreboard]

I have only one USB port connect to my PC.
This is my connection

[openscoreboard]

oooohhhh!!!
I think I understood it now.
It is necessary to connect a second USB to the GPIO5 (D +) and GPIO4 (D-) pin.
This second USB is the works as HID
Is correct?

[cnlohr]

Yep

[openscoreboard]

Now this is my setup

One USB for flash and other for HID

This is my dmesg now...

[cnlohr]

It is likely you've either flipped the D+/D- pins or some issue with the pullup resistor being large enough, etc.

I have an similar issue with my nodemcu, i tried to flash my own build of page.mpfs with the docker container and make burnweb and i tried to flash page.mpfs from your github repository. There appers no wifi network and dmesg says the following:

The last week i tried connect a wemos d1 and dont work for me.

I think that my firmware isnt ok.
Is there a link to donwload the firmware pre-compiled?

Thanks

[joBr99]

In this repository is a pre compiled firmware. You can flash it with the esptool and the following command:
esptool.py -b 115200 --port /dev/ttyUSB0 write_flash 65536 web/page.mpfs

As I have already said it does not work for me, I will attach my compiled firmware too.

page.mpfs.zip

[cnlohr]

The page.mpfs is only the webpage... you'll need both the 0x0000 and 0x4000 binaries. I don't have them handy, sadly.
