Keyboard.write(65);// sends ASCII value 65, or AKeyboard.write('A');// same thing as a quoted characterKeyboard.write(0x41);// same thing in hexadecimalKeyboard.write(0b01000001);// same thing in binary (weird choice, but it works) 写入的参数可以是这样的,返回值是一个字节数 还有一...
Now i want to use an USB-Keyboard as Input Device for an Esp32 - an found an Library from EspressIF witch uses an software Interface ( ESP32-USB-Soft-Host ) for the Interfacing of the USB-Device. First Try´s failed because of many compiling Errors from ArduinoIDF - witch i assume...

I'm currently building a USB keyboard using the ESP32-S3 and when upgrading to the latest Arduino Core, the reporting of LEDs (Caps Lock, Num Lock, etc.) did not happen anymore, even though the typing works. Downgrading to 2.0.13 makes the code work again. I attached a minimum reprodu...
I need to have the ESP32-S3 act as a USB host so I can plug a keyboard into it. Thus far I have not been able to find out any information on how to do this. Would someone please point me in the right direction. The examples are quite limited for host applications....
Is this a problem with my linux? lsusb does show the device, usbhid-dump does show the hid device as well. Veda88 Posts:3 Joined:Tue Sep 03, 2024 8:48 am Re: USB keyboard does not receive leds PostbyVeda88»Fri Sep 06, 2024 1:18 pm ...
It basicaly acts as a USB HID Device sending Keyboard characters. GND VCC D- D+ are connected via AWG24 Tefzel cable to a USB Screw Terminal. Version 1: 50cm cable, No problem, everything works fine continuesly! Version 2: Using 150cm cable. initially everything works fine for 30-...
I looked all over the internet and found that there was no project out there that converted the USB from a USB Mouse/Keyboard, sent the signals to the ESP32, processed them, and transferred the signals to the Windows computer to act as HID input. ...
I think the likelihood of this ending up as part of Espruino is very low unless Olimex got involved in the software - it's not anything on the ESP32 itself, so any work done would be specific to Olimex's one board with the PIC microcontroller on it - and there's really no reason ...
