A simple bug inside ps2keyboard libraries files

Hi guys;

When I download the library to use a PS2 Keyboard at this site http://www.pjrc.com/teensy/td_libs_PS2Keyboard.html

and I try the sample program, the IDE yell “dataPin” not in this scope ← The scope message… and it has something to do with this function : keyboard.begin(DataPin, IRQpin ); Ok It is not compiling…Humm…

OK …So I open PS2keyboard.cpp and PS2keyboard.h with Microsoft Visual Studio .NET 2003 with C++ ( <— expensive IDE ) to check what is going on. In the .h file this line :

this section in the h file I change.

static void begin(uint8_t data_pin, uint8_t irq_pin, const PS2Keymap_t &map = PS2Keymap_US);

I change the data pin into data_pin and irq_pin and save the h file.

And in the cpp file : I change to all data pin to data_pin and irq_pin except DataPin because it is declare at the begining the cpp file. And I save the cpp file.

I re-compile, it work and the library even work on an old AT keyboard that I was testing even an AT Keypad I bought at Active Surplus for $5.00. Cool heh ! 8)

I hope it help other with this infomation.

This section in the cpp file I change.

void PS2Keyboard::begin(uint8_t data_pin, uint8_t irq_pin, const PS2Keymap_t &map) {
  uint8_t irq_num=0;

  DataPin = data_pin;
  keymap = &map;

  // initialize the pins
  pinMode(irq_pin, INPUT_PULLUP);
  pinMode(data_pin, INPUT_PULLUP);
  pinMode(irq_pin, INPUT);
  digitalWrite(irq_pin, HIGH);
  pinMode(data_pin, INPUT);
  digitalWrite(data_pin, HIGH);


please modify your post as the tags got mixed up a bit

thank Rob; … better now…
