Hi ive been trying to setup TMK PS/2 to USB converter using Arduino Nano atmega328p with Makefile.vusb. The keyboard powers up and the LED's blink on the Arduino when keys are pressed but the keybaord doesnt output any characters.
I have CLOCK connected to PD5 pin and DATA connected to PD2 pin but it still doesnt work.
Makefile.vusb:
# Target file name (without extension).
TARGET = ps2_usb_vusb
# Directory common source filess exist
TMK_DIR = ../../tmk_core
# Directory keyboard dependent files exist
TARGET_DIR = .
# keyboard dependent files
SRC = keymap_common.c \
	matrix.c \
	led.c
ifdef KEYMAP
    SRC := keymap_$(KEYMAP).c $(SRC)
else
    SRC := keymap_plain.c $(SRC)
endif
CONFIG_H = config.h
# Use USART for PS/2. With V-USB INT and BUSYWAIT code is not useful.
PS2_USE_USART = yes
# V-USB debug level: To use ps2_usart.c level must be 0
# ps2_usart.c requires USART to receive PS/2 signal.
OPT_DEFS += -DDEBUG_LEVEL=0

# type "make clean" after changing this, so all files will be rebuilt

# Processor frequency.
#   Normally the first thing your program should do is set the clock prescaler,
#   so your program will run at the correct speed.  You should also set this
#   variable to same clock speed.  The _delay_ms() macro uses this, and many
#   examples use this variable to calculate timings.  Do not add a "UL" here.

Does everything look ok? Did i configure the files wrong? Im temporarily out of ideas hopefully theres a way to get it working
