HID-Serial adapter for using the LPC810

[bequest333]

Hi,

I am using Mr.Diego Mariano López customers' USB1.1 stack.
It was transplanted into LPC810.

Attached source is HID-serial adapter which has confirmed the operation.

(1)Parts list
USB connector
LPC810
Resistor 10k
Resistor 1k5
Condenser 104
Diode x3

(2)LPC810 Pin assignment
1.Reset (PIO0_5)
2.PIO0_4
3.RXD (PIO0_3)
4.TXD (PIO0_2)
5.D- (PIO0_1)
6.VDD
7.VSS
8.D+ (PIO0_0)

(3)Technical information
Serial data transfer amount 1byte (Max 8bytes,You need to rewrite HID Report Descriptor)
Baud rate 9600
Program Size 3.2k bytes (80%)

How does it looks on the host side (e.g. windows)?  As a standard serial port?

Hi,zapta

This is not a CDC.

CDC can be implemented in USB1.1, but it is operating outside the standard.

From the window it looks like the following.

USB Human Interface Device

Driver installation because it is HID is not required.

<How to access the HID device.>
1.You want to create an application on their own.
2.Use the YAT. (Yet Another Terminal)
http://sourceforge.net/projects/y-a-terminal/
3.It uses a loop back host of attachments.

Hi,All

I've updated the LPC810 firmware.

Added feature
1.To change the baud rate from the host.
2.Manipulating the communication conditions from the host.
 (UART ON/OFF, data length, parity, stop bits)
3.2bits of the output port operation.



<Pin assignment>
1.DTR (PIO0_5)
