PS/2 to USB keyboard converter for Teensy with mousekeys and NKRO
« Reply #100 on: Thu, 12 January 2012, 04:24:32 »
REVENGE, thanks for the link.

Hmm, those waveform will not work with my converter on Teensy too. I think AVR USART hardware can handle that fast signal without timing problem.

While my Teensy converter uses PS/2 handler implemented with software(poor my C lang), V-USB converter uses this USART hardware to reduce cycles for PS/2 handling. Of course you can use the USART hardware on Teensy too.

You have two option to take: building a V-USB converter or using USART on Teensy one.
 Looking these files will help you.

So, I haven't figured out how to work your PS/2 via USART implementation, but I did build the Teensyduino PS2Keyboard implementation and it seems to work fine in serial mode. In fact, that thing also seems to work just fine with my set 3 terminal model F. Any limitations to using this as the basis for a converter?

I just looked over PJRCs' PS2Keyboard source. It uses an interrupt routine for PS/2 handling instead of USART hardware I meant, and seems to support only Code Set 2. (Code Set 2 and 3 shares same code of alpha/numeric keys, but as for modifier, function key and etc. codes differ.)
I think USART implementation has no limitations at all except that you can't use USART function for another.


I can come up with three implementation method to handle the PS/2 signal.
1. simple and stupid wait & read loop(intensive use of cpu cycles)
2. Interrupt(a few use)
3. USART hardware(not use at all)

I used method 1. to implement my converter on Teensy and it was OK in most case.
I used method 3. to implement my converter with V-USB because it uses clock cycles intensively and very timing sensitive. I could not use even method 2 with V-USB due to very tight timing issue.

Hmm, do you have any hints for using the USART implementation with Teensy? I think I've changed the registers in the config header file to the ones used by the 32u4, but I get nothing, and I have no idea how to debug it either. :(

I added some files to support USART implementation.

Try latest source and do 'make -f Makefile.pjrc_usart'.
Note that pin configuration for this is different from 'simple and stupid' one. Connect Clock line to PD5 pin and Data to PD2.

Sweet, getting it now to build. For the makefile and config, I actually had almost exactly the same thing as you (even named the files the same, teehee....) except my pin defs are different. I'm guessing I can't customize those and have to use what you set?

Right. USART pins are fixed depending on MCU and my configuration is for Teensy(ATmega32U4).

F2 is not present on ATMega32U4(Teensy 2.0).
But why do you find F2? you need D2 and D5 as I described before.
You need sleep? Me too :) I got to go to bed now.

No, I needed to wake up and start paying attention, that's what. :P

Yeah, so it seems to work fine! Good stuff. The lock keys respond a little sluggishly, but I'm guessing that's because there're still some LED stuff going on? Is it even possible to support lock LEDs?

Nice!

Ah... USART is only for receiving, unfortunately it still uses 'simple and stupid' method to send command like SET LED(converter->keyboard communication).
It seems to have the timing issue when sending to the keyboard.

This patch might cure the problem by some chance. Try this.

Hmmzord, I'll try the patch later tonight. A more immediate problem is that I need to solder something (wire, pin, whatever) to D5 -  I'm using my hand to touch a wire to the contact and to do testing (:-/). Another crazy idea: would it be possible to use one of the digital pins exclusively to send lock LED commands to the keyboard? From what I understand, using the UART / USART is independent of regular programming.

Hi, does anybody know if this software will fit onto an AT90USB162 (16k flash, 512 ram)?

I can buy either AT90USB162 or ATmega32U4, but I'd prefer the smaller one.

mich,
I built binary with default configuration for at90usb162 though I have no chip to program and try.
I think this will fit on the chip and also you can reduce size by removing unused keymaps and functions.

Until fairly recently my converter worked on a '162. The limiting features are: only 512 bytes of RAM, and only 4 USB endpoints.

Weird, I thought I posted already...

It mostly works, but there are a few quirks. For some reason, the forward slash key does not work consistently. Sometimes it makes, but doesn't break, sometimes it doesn't repeat, sometimes it doesn't work at all. On my other PS/2 to USB converter and native PS/2, it works fine. This is with regards to the Monterey.

Thanks.
The patch seems to cure the LED problem.

As for wierd key things, it is probably not a real bug or problem.
To activate cursor keys and mouse keys keymap layers, '/' and ';' are used as Fn key and normal key at same time.
Try '/' + hjkl to move cursor and ';' + hjkl to move mouse cursor. See the article page or keymap.c for detail.

This incur some side effects, as you described these keys has no key repeating and a legend is registered on key released not pressed.
(To register key you must press and release the key in about 200mS and to repeat key you can double tap the key and hold in that time.)
These side effects are not occurred on dedicated Fn keys. You can use unused key for this such as right windows key or something.

These functions might impose frustration on you in some situation.
This default keymap is just to demonstrate the functions of my firmware, you can change this keymap by editing keymap.c.
Or pressed LShift + RShift + 1 to switch normal QWERTY keymap without these Fn keys temporarily.

No reason. V-USB is awesome library you can support various USB functions including NKRO, those protocols. (TMK doesn't support NKRO with V-USB atm.) TMK's V-USB code supports System/Media key usages.
https://github.com/tmk/tmk_keyboard/blob/master/protocol/vusb/vusb.c#L337

But I've not used V-USB myself and not updated its code for long time, I'm not sure it still works.

Hey hasu,

I was able to setup my PS/2 to USB converter thanks to your code.

Now I have a fully functional Dell AT101W via an ATMega328P via VUSB. :)

Just wondering, how do I get the keyboard to be able to wake the computer from sleep?
With a Logitech Keyboard, I see the Power Management tab under Device Properties in Windows, but no tab for the Converter.

Does it have to do with missing Power Data and Power Capabilities info?

Plus under
Code: [Select]
powercfg -devicequery wake_armed in CMD the Converter isn't listed... meaning that it doesn't support wake from sleep.

Thanks!

It is definitely possible to implement the feature on V-USB, but I have no time and plan  to do so for a while.

First, with this converter you never need any diodes. Maybe, you are in wrong thread.

Make sure your keymap is clean and plain without fancy functions. And check your hardware.

Is it possible to programm it via serial port or ISP programmer is needed.

Could you, please, post some instruction how to do it? I`m real beginner.

Can't seem to get this to work. Im using a Pro Micro and have Data hooked up to PD1 and clock to PD0 and nothing happens when i hook up the converter exept it shows up in my hardwarelist as a keyboard.
I've added a 4K pull-up resistor to the data line from VCC and that made the keyboard light up when i hooked it up but its still not working. Do I need a pul-up resistor on the clock line aswell?

Ive changed the PS2_DATA_BIT to 1 and PS_CLOCK_BIT to 0 in the config on USART as the Pro Micro does not have PD5 (it does but thats one of the internal leds).

Use two pullup resistors on both signal lines, just in case.
You can't use PS2_USART on Leonardo and Pro Micro, use PS2_BUSYWAIT(or PS2_INT) instead. In particular PS2_BUSYWAIT works with any pin combination, it would be useful. Also PS2_INT works for your pin configuration.

It seems people are confused by flexible pin configuration and variation of protocol implementations, If I have  time I'll change pin usage same as Soarer's and use busywait impl by default to allow users chaging pins freely.

Don't have a lot to say in this thread yet - except for thank you!

I just got a few IBM Model M keyboards from a friend of mine. So, I ran down to the local Microcenter, bought a Teensy 2.0. I sacrificed an old PS/2 extension cable I had lying around, and 10 minutes later I had everything wired up. Installed the toolchain and had the firmware running in another 15 minutes.

It's rather ugly, but I've got this all hooked up to my Mac and I'm happily tweaking the key maps to swap in more useful keys. Hoping to wrap my head around the source code some more to see if maybe there's anything more interesting I can do! I might also try embedding a Teensy in one of these keyboards, just to make everything cleaner.

Again, thanks for your work!

Hi, is it also possible to use teensy 2.0 vice versa. So that I can connect my usb-keyboard via teensy to the ps/2 input of my computer? And furthermore, will your firmware provided work with this?

No.
1) Teensy 2.0 doesn't support USB keyboard input.
2) My firmware doesn't support PS/2 output.

Thanks a lot for your reply..  ;)  Do you know a way to realize this? Because despite USB-connectivity of my keyboard I would prefer PS/2. (Although my keyboard doesn´t support PS/2, so that a simple USB A to PS/2 connector is useless). The Reason for me is, to get the real NKRO (which is limited via USB to 6KRO). Also I would be able to send key events like system control (power down, sleep, etc. ..)

Thank you for a good work, Hasu!

Can I ask you if this converter could be used with a Atmega328-based controller, say, Arduino Nano?

yes, use vusb stack.

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:
Code: [Select]
# 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 = .

# Processor frequency.
#   Normally the first thing your program should do is set the clock prescaler,

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

Your pin configuration is wrong. as config.h indicates, you have to use pd0/rxd and pd4/xck pin for atmega328p.

I moved the wires CLOCK and DATA to PD0 and PD4 but the result is the same.

Post pic of your wiring.
Did you connect DATA to PD0 and Clock ot PD4? Do you have pull up resistors?
And do you have components(zeners and registers on INT0/INT1) for VUSB?
