uPSD3300 Series Design Guide for DK3300-ELCD Using KEIL
3.3.2 Physical Connections
■ Connect RLINK-ST to your PC/Laptop using the supplied USB cable and let the USB driver
install on Windows.
■ Connect RLINK-ST ribbon cable to the JTAG connector on the DK3300-ELCD circuit
board.
■ Make sure that the Board is powered up using the Universal Adapter supplied with the kit
and ensure that it is functioning. (See that the LCD display shows the text).
■ Make sure that the Jumpers are set correctly. (Refer to APPENDIX A. at the end of the
document for Jumper settings).
3.3.3 Installing Keil uVision
Note: the PSDsoft software must be installed first.
ST provides the Evaluation/Demo version of Keil with the DK3300-ELCD which is fully func-
tional and licensed but limits Code size to 2KB. Users need to contact Keil (http://
www.keil.com) for acquiring a full version of uVision tools without limitations.
In this application note the simple design example used can be used with the demo version.
■ Use the executable uVision file to install the demo version of Keil on your computer. The
Keil uVision tools provide an Integrated Development Environment that combines project
management, source code editing, and program debugging in one single powerful
environment.
The Keil ULINK connects directly to the JTAG pins of the STMicroelectronics (Turbo) uPSD
device. There is only a JTAG connector required on the hardware.
The JTAG interface provides a broad range of debug features on the standard production chip.
It allows you to debug the application which is running on an unmodified target system with
minimal hardware overhead. In addition, the JTAG interface may be used as high-speed inter-
face for programming the on-chip Flash.
JTAG debugging provides several features that are fully supported by the Keil uVision Debug-
ger:
■ Start / Stop the microcontroller.
■ Up to 4 code or access breakpoints. Even an address range is supported.
■ Read/write access to whole address space (data, code, xdata).
■ Single step or procedure step program execution.
■ Instruction Trace
Additional features will be shown with the simple demonstration program used with this appli-
cation note in the next section.
With the uVision IDE you can download and test your applications in the same environment.
This shortens the development cycles.
