ESP32 Bluetooth command to take a picture

[stefan.erni]

Hi Martin

Before I compile the Keyboard.fcfx
I would like to ask you in which folder I have to copy the file Keyboard.fcfx.
The program needs an include file "ble_hidd_demo_main.h"
Does this mean that Keyboard.fcfx .. should be copied to the same folder?

regards

Stefan

Hi Stefan,

The fcfx file in your project folder - attempting to compile this (from within FC) will create a new directory with the name of the project (in this case 'keyboard') contents of the zip file to copy to this new directory.

See my post on esp bluetooth mesh for more detail..

So - a bit more of a useful setup now.

Handles ASCII characters (7 bit) with the exception of '@' and '£' - I had an American keyboard list - the demo now 'types' a list of character codes and the 'key equivalent. The missing keys should be easily added (2 bytes in the lookup table)

..
65 A
66 B
67 C
..
97 a
98 b
..

So now SendStr accepts strings such as "Hello World\tTabbed+content\r"

Each key is now 'pressed' for 10ms and then released. I suspect faster rates are possible.

As an aside the ascii to keycode routine will work with any HID setup and is very compact - changing the lookup table from an array to a lookup table would save valuable RAM (128 bytes) on smaller MCUs too.

FCs - compile to hex works but need to upload using idf.py. Compile to C doesn't seem to regenerate esp-project.c?

Next to have a play with mouse commands?

Hi Martin

Compile to C is working and give a keyboard.c

Firts time Compile to hex give a error but it creat the main folder.

So I copy the zip files in the main folder and

Second time Compile to hex run bether.

Hi Stefan,

You need to create the project file as per first downloads then update as per second.

1) save Keyboard.fcfx somewhere (say C:\Projects) open in FC and compile to hex (this will fail - no matter it creates the directories needed)
2) copy in the contents of the first zip (to c:\projects\keyboard)- and then contents of 2nd zip file to the directory (c:\projects\keyboard\main)
3) should now be able to compile to hex in fc.
4) upload using idf.py -p COM5 flash (change 5 as required for your com port)

If you pm an email address I'll send a 'complete' setup - it was too large to upload here even as a zip.

The errors indicate that the CMakeLists file isn't updated - see https://flowcode.co.uk/forums/viewtopic.php?f=3&t=1511 - where I break the steps down a bit more....
