Development of USB interface to microcontroller

[padmavathi]

hii...i need to transfer data between two microcontrollers with USB interface.the IC i am using is PDIUSBD12 and the microcontroller is AT89C51ED2.i need a sample code in assembly language.
can anyone help me plzzzz.

Hi you,
I haven't code for this but why do you use the USB interface to tranfer data between two MCU? Because the USB interface is allway used for tranfer betwwen the PC and MCU
I thinhk if you want to tranfer data betwwen 2 MCU, let you use the simple menthod to do it ex : I2C interface(good if the MCU support the I2C interface), RS232 or you can use the IO pin
The USB interface is most userful when you want to communicate the MCU to PC (Endpoint IN,endpoint out)

Hi

Check this link under Philips PDIUSBD11 and PDIUSBD12
**broken link removed**

but it's better to use RS232 if you are connecting 2 MCU's

the USB data must transfer between the USB host and USB device.In the USB bus i may have more than one device ,bu it should and must have a USB host .and PDIUSBD12 is a device chip. suggest you see the SL811(a USB host chip)
