ISP1183 Low-Power USB Peripheral Controller PC Eval Kit

1. Introduction

The ISP1183 is a cost- and feature-optimized Universal Serial Bus (USB) peripheral. It is

typically used in any microcontroller- or microprocessor-based system. The ISP1183 is a

full-speed USB Peripheral Controller with up to 14 configurable endpoints. It has a fast

general-purpose parallel interface to communicate with many types of microcontrollers or

microprocessors.

The ISP1183 has 2462 bytes of internal First In, First Out (FIFO) memory, which is

shared among enabled USB endpoints. The type and FIFO size of each endpoint can be

individually configured, depending on the required packet size. For increased data

throughput, isochronous and bulk endpoints are double-buffered.

To a microcontroller, the ISP1183 appears as a memory device with an 8-bit data bus

and a 1-bit address bus. The ISP1183 only supports a nonmultiplexed address and data

bus.

The ISP1183 PC evaluation (eval) kit uses two PCs as a complete USB development

environment, a host PC with USB host capability and a peripheral PC running the

ISP1183 firmware. The ISP1183 eval board is plugged in the peripheral PC as a USB

peripheral.

With this set up, you can easily evaluate the features of the ISP1183, and develop

firmware and product prototype, without being limited by the choice of a microcontroller.

The firmware is written in C, that supports Borland Turbo C for x86.

Fig 1 shows the ISP1183 eval board.

2. System requirements

For the host PC:

• PC with USB motherboard or add-on card.

• Microsoft Windows 98 and Windows 2000.

For the peripheral PC:

• PC with Microsoft DOS 6.x.

• ISP1183 eval board, as shown in Fig 2.

NXP Semiconductors UM10044

ISP1183 Low-Power USB Peripheral Controller PC Eval Kit

For the firmware development:

• x86 CPU platform: Borland Turbo C++ 3.0 or above.

• ISP1183 eval diskette.

3. Jumper settings on the ISP1183 eval board

The ISP1183 eval board is plugged into the peripheral PC. It will occupy I/O and IRQ

resources of the peripheral PC. To avoid possible conflicts in settings, remove all

unnecessary cards from the peripheral PC. Sound cards and network cards may cause

IRQ conflicts.

Jumper JP1 enables and disables the level-shift module.

JP4 sets the IRQ number for the ISP1183 eval board. Default setting is IRQ5 as shown

in Table 3. Short Intx_IRQ and pin 5.

IRQ5 Creative SoundBlaster and compatible sound cards always occupy this IRQ, by

default. If this type of sound card is installed, check its settings or remove it.

Some network cards may also use this IRQ.

IRQ7 Used by parallel port, by default. May cause printing problem on peripheral PC.

4. I/O mapping

The ISP1183 eval board occupies eight I/O locations. The base address is 368h.

5. Installing hardware, firmware, INF and driver

The procedure to install hardware, firmware, INF and driver is as follows:

1. Switch off the peripheral PC.

2. Remove all unnecessary cards on the peripheral PC.

3. Plug the ISP1183 eval board in the ISA slot of the peripheral PC.

4. Switch on the peripheral PC.

5. On the peripheral PC, under the DOS mode, run firmware 1183FW.EXE.

If it is the first time that the eval board is connected to the host PC, the host OS Device

Manager will prompt for the installation of INF and drivers.

6. Select the location of D13TEST.INF and D13TEST.SYS from the ISP1183 evaluation

diskette and complete the installation procedure.

6. Using the host applet

Test applet D13TEST.EXE exercises all the ISP1183 endpoints as shown in Fig 3.

Table 9 shows a description of endpoints operation on the ISP1183 eval board.

Table 9. Description of endpoints operation

The test applet and the ISP1183 eval board support three test modes: loopback, print

and scan. The firmware uses I/O accesses on this endpoint.

Endpoint number Endpoint type Operations

5 ISO-OUT This pipe is defined as an isochronous OUT pipe.

6 ISO-IN This pipe is defined as an isochronous IN pipe.

3 Bulk-OUT This pipe is defined as a bulk OUT pipe. Supports DMA.

4 Bulk-IN This pipe is defined as a bulk IN pipe. Supports DMA.

Three test modes:

• Scan mode: In this mode, the ISP1183 eval board acts like a scanner. It sends data

packets to the host PC as fast as possible. Use this mode to evaluate the

isochronous IN and bulk IN transfer rates.

• Print mode: In this mode, the ISP1183 eval board acts like a printer. It receives data

packets from the host PC as fast as possible. Use this mode to evaluate the

isochronous OUT and bulk OUT transfer rates.

• Loopback mode: In this mode, the ISP1183 eval board receives data packets on the

isochronous OUT (or bulk OUT) endpoint and sends them back to the host PC on

isochronous IN (or bulk IN) endpoint. Use this mode to test the data integrity of

transfers.

The Buffer Size setting of the test applet is determined by firmware and hardware ability

of the eval board. For ISA mode, the maximum size is limited to 64000 bytes for the bulk

transfer and 256 bytes for the ISO transfer. For ISO scan mode, if you need to change

the buffer size, print a buffer of the same data size first. By default, Buffer Size is set to

64000 when the test applet is launched. Change Buffer Size to 64 before starting the

test.

Repeat Times for the loopback test controls the numbers of iterations of loopback, which

is useful for debugging. By default, Repeat Times is set to 0 when the test applet is

launched. To run the test infinite times, set Repeat Times to –1.

7. Testing control endpoints using standard USB compliance tool

To test control endpoints using the standard USB compliance tool:

1. Run the USB compliance tool.

The USB Compliance Tool1window appears, as in Fig 4.

2. Connect a USB peripheral.
