Hi, you must use ESPjoy interface from Antonio Villena. [https://antoniovillena.com/product/espjoy/](url) . It simulate keyboard keys press. You also need the green USB to PS/2 adapter.

[https://github.com/dacarsoft/DB9_2_Keyboard/tree/DB9_2_Keyboard_ESPectrum](url) You can use a generic ATmega 32U4 boards like Arduino Pro Micro or Arduino Leonardo. Program it with Arduino IDE using "Arduino Leonardo" as board target. And see on...

Also You must have to use a AVR programmer because you have to program the ATmega chip by this ISP pins.

On the ATmega32U4 compatible card you use the USB socket (micro-usb ?) with a standard USB cable. On the another end you use a little green USBPS/2 adapter [https://share.temu.com/5SZx1jz1ZpA](url) to...

OK. Good luck. Don't forget to swap (uncomment) the define lines on the source code : **#define AVILLENA_BOARD //#define BLUEPILL_BOARD** 

ISP pinouts to program the chip. (you can use a Arduino UNO as AVR programmer) 

I also have this issue. I think when i have changed to the right board type on the menu the error disappear.Sorry. I'm in Portugal, i can't help until my...

Program it with Arduino IDE using "Arduino Leonardo" as board target. Somes warnings but compile or use the .HEX file: [DB9_2_Keyboard_ESPectrum.zip](https://github.com/EremusOne/ESPectrum/files/15287382/DB9_2_Keyboard_ESPectrum.zip)

ESPjoy interface from Antonio Villena:  

For the second joystick DB9 is: Bluepill ATmega 32U4 board pinout: Arduino 10 -> DB9 pin 1: Up Arduino 16 -> DB9 pin 2: Down Arduino 14 -> DB9 pin...
