Im trying to run the example of the Keyboard to Usb host connected in Arduino Mega .The output i get is in a weird language need help im facing such problems for almost most of my usb shield codes.Below are the codes example and the output image.
#include <avr/pgmspace.h>
#include <avrpins.h>
#include <max3421e.h>
#include <usbhost.h>
#include <usb_ch9.h>
#include <Usb.h>
#include <usbhub.h>
#include <avr/pgmspace.h>
#include <address.h>
#include <hidboot.h>
#include <printhex.h>
#include <message.h>
#include <hexdump.h>
#include <parsetools.h>
class KbdRptParser : public KeyboardReportParser
{
void PrintKey(uint8_t mod, uint8_t key);
protected:
virtual void OnKeyDown (uint8_t mod, uint8_t key);
virtual void OnKeyUp (uint8_t mod, uint8_t key);
virtual void OnKeyPressed(uint8_t key);
};
void KbdRptParser::PrintKey(uint8_t m, uint8_t key)
{
MODIFIERKEYS mod;
*((uint8_t*)&mod) = m;
Serial.print((mod.bmLeftCtrl == 1) ? "C" : " ");
Serial.print((mod.bmLeftShift == 1) ? "S" : " ");
Serial.print((mod.bmLeftAlt == 1) ? "A" : " ");
Serial.print((mod.bmLeftGUI == 1) ? "G" : " ");
Serial.print(" >");
PrintHex<uint8_t>(key, 0x80);
Serial.print("< ");
Serial.print((mod.bmRightCtrl == 1) ? "C" : " ");
Serial.print((mod.bmRightShift == 1) ? "S" : " ");
Serial.print((mod.bmRightAlt == 1) ? "A" : " ");
Serial.println((mod.bmRightGUI == 1) ? "G" : " ");
};
void KbdRptParser::OnKeyDown(uint8_t mod, uint8_t key)
{
Serial.print("DN ");
PrintKey(mod, key);
uint8_t c = OemToAscii(mod, key);
if (c)
OnKeyPressed(c);
}
void KbdRptParser::OnKeyUp(uint8_t mod, uint8_t key)
{
Serial.print("UP ");
PrintKey(mod, key);
}
void KbdRptParser::OnKeyPressed(uint8_t key)
{
Serial.print("ASCII: ");
Serial.println((char)key);
};
USB Usb;
//USBHub Hub(&Usb);
HIDBoot<HID_PROTOCOL_KEYBOARD> Keyboard(&Usb);
uint32_t next_time;
KbdRptParser Prs;
void setup()
{
Serial.begin( 115200 );
Serial.println("Start");
if (Usb.Init() == -1)
Serial.println("OSC did not start.");
delay( 200 );
next_time = millis() + 5000;
Keyboard.SetReportParser(0, (HIDReportParser*)&Prs);
}
void loop()
{
Usb.Task();
}
