Build DIY USB OTG ANDROID

No Comments »

This is very Simple way to modification standart usb converter to OTG USB. The most Mini or Micro USB to USB converters are not work if you want to use it for OTG converter, because the 4. pin of the micro usb plug is not connected. This below is an original cable schematic : If you want to use it for working OTG adapter you have to connect the micro usb connector 4. pin to GND (5. pin). Like this below : This schematic is working me. Let to try this stuff. Original document USB OTG ......

The AVR embedded web server reference design is designed for integration in digital equipment. The AVR embedded web server can be plugged into any Ethernet interface and communicate wi th a standard web browser. Suppose the AVR embedded web server is embedded in several units in a house. Every server is connected to the network. A computer located at home as on Figure 2 controls all devices and can receive requests from other computers on the Internet. The web server is identified by it ......

The following picture shows the assembled GLCD kit. The default microcontroller that comes with the development board is PIC16F886. The IDC cables connect the 8-bit data port of the GLCD to PORTC, and the GLCD control signals to PORTB. Table 1 shows the details of the mapped pins.A SMT potentiometer is provided on the backside of the GLCD adapter to adjust the contrast of the display. The GLCD adapter has got an on-board transistor switch for turning the GLCD back-light on and off. The IDC cab ......
