Keyboard with boot protocol enabled about ch55xduino

[DeqingSun]

I can confirm the emulated keyboard does not work on the boot screen of a Mid-2014 macbook pro while a real Dell keyboard does work.
So there must be some implementation problem in the boot protocol. I will take a look soon.

For progress record:

There is some progress in https://github.com/DeqingSun/ch55xduino/blob/ec3b8958397dac77035ab4ae40cd06331b51320d/ch55xduino/ch55x/libraries/Generic_Examples/examples/05.USB/HidKeyboard/src/userUsbHidKeyboard/USBhandler.c that deal with HID report access on EP0. More work need to be done to do get EP0 IN work properly.

Hello i am sorry for not returning in time i saw your post in my mail today i have variety of old notebooks i will test and post the results thank you so much.

Hello i tested new update on 3 laptops ;
Dell Latitude E6330
Fujitsu Lifebook LH532
Asus N550JV

it works on windows but it didn't work in bios screen
i also changed keyboardProtocol varible but results were same;didn't work
(//0 is boot protocol, 1 is report protocol
__xdata uint8_t keyboardProtocol = 1; from 1 to 0 but it didnt work again)
my humble opinion i suggest you to check stm32 libraries and HID-project library. i was able to make it with stm32 mcu using cubeide generated code for arduino(pro micro) i used HID-project both of them worked.

Thanks for sharing. I suppose there must be some USB request that I did not handle properly.

I'll check it this weekend with a real windows machine. I suppose the bios in windows and mac still handle the USB differently.

I've tested it on
Lenovo Thinkpad t410 2518-f4u 2010
Acer Aspire 4930 JAL90 2008
They both work in Bios.
I'll take a look at the other projects.

I tried to use

      Keyboard_press(KEY_DOWN_ARROW);
      delay(100); //a quick capslock press is not recognized on mac
      Keyboard_release(KEY_DOWN_ARROW);

And the cursor can be moved in BIOS
