change wireless keyboard #1
Comments

Hi
You want to change code to carry keyboard and mouse signals over wireless
spi and at receiver translate to usb ?

… can I modify this code to convert spi protocol to USB keyboard mouse and
make a wireless connections use nrf24l01?

certainly. I see there's sources of nrf24l01 chip to transfer data by spi, so i hope to modify your source code to use this. firstly use a transmiter (arduino eg atmega328p) to translate scancode to spi and then receiver (arduino /teensy atmega32u4) to do the following this eventually translate ps/2 keyboard's scancode to hid code. do you think is it feasible? I want to experiment by conncet two arduino by spi wire first, if ok add wireless code. is it feasible? |

Aim of this project is to make usable (not like translators on the market :) ) translator for keyboard and mouse which uses ps2 interface to connect them to new PC's which have only usb ports. firstly what does this sentence mean? what is the different between yours and market's converter/ translator? With V-USB you can use this converter on ATmega(168/328) but it doesn't support NKRO at this time. Circuit: is it your way to deal with ps/2 signal by atmega 328? |

Sorry for late response

Its ok but i would transmit only hid code to receiver
I want to experiment by conncet two arduino by spi wire first, if ok add
wireless code. is it feasible?
thank you.
and another question, is your converter single direction or bi-direction?
could the keyboard receive the command from host?
USB must be bidirectional connection and it actualy receives commands which
i use to switch leds
… thank you again.

Aim of this project is to make *usable (not like translators on the
market :) ) translator* for keyboard and mouse which uses ps2 interface
to connect them to new PC's which have only usb ports.
firstly what does this sentence mean? what is the different between yours
and market's converter/ translator?
Market translator have poor performance. They have all sorts of bugs like
repeat last stroked key forever switching of pressed key and others
and secondly it seem like your converter realize the usb protocol by
programming? am i right? I see your code is more complex than others eg tmk
which used atmega32u4 usually and pjrc's ps/2 routine.
V-USB Support
Yes i use Vusb and it is not easy to understand in usb asm routines but i
think you should just copy it in receiver side which will be just sending
received hid codes
With V-USB you can use this converter on ATmega(168/328) but it doesn't
support NKRO at this time.
NRKO is keyboard feature not translator

is it your way to deal with ps/2 signal by atmega 328?
I use one of int to handle keyboard and uart for mouse (i'm not sure if
INT1 is connected to D- in my translator)

thanks after I read source code of lots of PS/2 USB converter I decide transfer USB HID. among these projects 1yours 2 nsd20463/ps2_kbd_to_usb_adapter#3 |

what is this means？ |

It seams but you shuld ask tmk ;)

… what is this means？
extern const uint8_t keymaps[][MATRIX_ROWS][MATRIX_COLS];
is it a pointer？for a simplified example int p[][3][4] means？

my dear friend and teacher, why the new errors appear? Severity Code Description Project File Line the last question, can you remember what is the pin connexion of two ps/2 and usb? |

Try release build and my studio version is 6.0.1996 sp2

… my dear friend and teacher,
build with atmel studio 7,some errors in keyboard.c,
some is
Severity Code Description Project File Line
Error 'odDebugInit' undeclared (first use in this function) ps2usb
K:\ps2usb-master\ps2usb\src\keyboard.c 159
Severity Code Description Project File Line
Error macro "odDebugInit" passed 1 arguments, but takes just 0 ps2usb

Severity Code Description Project File Line
Error implicit declaration of function 'waitForEnd'

why the new errors appear?
Severity Code Description Project File Line
Error implicit declaration of function 'cli'

Error implicit declaration of function 'sei'

K:\ps2usb-master\ps2usb\src\keyboard.c 134
this three errors I correct it by adding #include delay.h and interrupt.h.
and the left, I have no way and have to ask you
the last question, can you remember what is the pin connexion of two ps/2
and usb?
thanks again
