openscoreboard commented 6 years ago

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!!!

cnlohr commented 6 years ago

You need to flash the webpage.

Flash web/page.mpfs to 0x100000

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?

example

Thanks...

cnlohr commented 6 years ago

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 commented 6 years ago

I have a resistor with 1,2K

And this is the output dmesg

My steps

Thanks...

cnlohr commented 6 years ago

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 commented 6 years ago

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

openscoreboard commented 6 years ago

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 commented 6 years ago

Yep

openscoreboard commented 6 years ago

Now this is my setup

seleccion_014

One USB for flash and other for HID

This is my dmesg now...

cnlohr commented 6 years ago

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

joBr99 commented 6 years ago

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 commented 6 years ago

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 commented 6 years ago

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

joBr99 commented 6 years ago

Thanks, I overlooked that ... now it is working.

cnlohr commented 6 years ago

@joBr99 Would you mind uploading your binaries?

Hello guys.. I think I f*** it up. Today I boght this Module I share with you in the picture. image

I tryed to make it work but I couldn´t. I even flashed it on the memory addresses you shared. image.elf-0x00000.bin 0x40000 image.elf-0x40000.bin and web/page.mpfs to 0x100000 It kindda work.. but it is not the interface I am used to see on videos and it does not even send commands to the module. This is what everybody sees:

This is what I see:

Can you guys please help me? Thank you
