Hey,
I have a problem with my new usb host shield. I'm relatively new to the arduino platform, so I could use your help
Here it is:
I've bought a shield (http://www.circuitsathome.com/products-page/arduino-shields/usb-host-shield-2-0-for-arduino) and assembled it. I also checked the solderings. But when I attach it to my Arduino, it just gives no response. This is the example sketch I am running:
#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 MouseRptParser : public MouseReportParser
{
protected:
virtual void OnMouseMove (MOUSEINFO *mi);
virtual void OnLeftButtonUp (MOUSEINFO *mi);
virtual void OnLeftButtonDown (MOUSEINFO *mi);
virtual void OnRightButtonUp (MOUSEINFO *mi);
virtual void OnRightButtonDown (MOUSEINFO *mi);
virtual void OnMiddleButtonUp (MOUSEINFO *mi);
virtual void OnMiddleButtonDown (MOUSEINFO *mi);
};
void MouseRptParser::OnMouseMove(MOUSEINFO *mi)
{
Serial.print("dx=");
Serial.print(mi->dX, DEC);
Serial.print(" dy=");
Serial.println(mi->dY, DEC);
};
void MouseRptParser::OnLeftButtonUp (MOUSEINFO *mi)
{
Serial.println("L Butt Up");
};
void MouseRptParser::OnLeftButtonDown (MOUSEINFO *mi)
{
Serial.println("L Butt Dn");
};
void MouseRptParser::OnRightButtonUp (MOUSEINFO *mi)
{
Serial.println("R Butt Up");
};
void MouseRptParser::OnRightButtonDown (MOUSEINFO *mi)
{
Serial.println("R Butt Dn");
};
void MouseRptParser::OnMiddleButtonUp (MOUSEINFO *mi)
{
Serial.println("M Butt Up");
};
void MouseRptParser::OnMiddleButtonDown (MOUSEINFO *mi)
{
Serial.println("M Butt Dn");
};
USB Usb;
USBHub Hub(&Usb);
HIDBoot<HID_PROTOCOL_MOUSE> Mouse(&Usb);
uint32_t next_time;
MouseRptParser 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;
Mouse.SetReportParser(0,(HIDReportParser*)&Prs);
}
void loop()
{
Usb.Task();
}The only output I get is the initial "Start".
I did a little research and found that the Method Usb.getUsbTaskState gives me an error code 19, which is related to an error called "USB_DETACHED_SUBSTATE_ILLEGAL".
I am working with an Arduino Mega (ATMega 1280) and the Arduino Library by "Circuits@Home" (https://github.com/felis/USB_Host_Shield_2.0).
I would be very grateful if you could help me!
PS: If you need more information, just tell me.
PPS: aaand forgive me if my english is bad -.-
