Rev. B Page 3 of 16Although you can install the software onto any hard driveand into any directory, the remainder of this user guideassumes that you have installed the software at the defaultlocation of C:\ADuC.If you already have a previous ADuC8xx QuickStart Development System tool suite installed on your machine, this versionmay have also been installed by default at C:\ADuC. TheADuC8xx software tools installation automatically updatesany previous ADuC8xx tools in this directory.

UG-041Evaluation Kit User GuideTHE METALINK 8051 CROSS ASSEMBLERThe Metalink 8051 Cross Assembler takes an assembly languagesource file created with a text editor and saved with an .asmextension and creates two files: an output list file (.lst) and amachine language object file in standard Intel HEX format (.hex).The assembler displays ASSEMBLY COMPLETE, 0 ERRORSFOUND, indicating assembly of the file and creation of the hexand list files (that is, DemoCode.hex and DemoCode.lst) withthe assembly input file (that is, DemoCode.asm). If the assembler indicates assembly errors, view the list file (DemoCode.lst)to examine the errors. To view the list file, open it withMicrosoft Notepad or any standard text editor.The list file output (.lst) displays the results of the assembleroperation, including any syntax or other errors present in theoriginal source code.If the assembler returns an error message indicating a failure toread the A drive or a fatal error opening a file on the A drive,then it is most likely failing to find the MOD52 or MOD8xx filereferenced by the assembly file. Make sure all MOD files plusany other include files referenced in your assembly code arelocated in the C:\ADuC\ASM51 directory.The Intel HEX file (.hex) is used to program the part using theWindows serial downloader (WSD).USING THE METALINK ASSEMBLER2.In the C:\ADuC\ASM51 directory, double-click theASM51.exe executable.In the DOS window, enter the path of the assembly fileyou want to assemble. For example, to assemble theexample file C:\ADuC\Download\DemoCode.asm, enterC:\ADuC\Download\DemoCode.asm.The ASM51.exe program can be copied/moved to anotherdirectory to prevent typing in the long path name repeatedly.Make sure that the relevant MOD files are also moved withthe ASM51.exe program.For additional details on the use of the Metalink ASM51 assembler,refer to the ASM51 user manual at C:\ADuC\ASM51\ASM51.pdf.This manual is provided on the evaluation kit CD.08412-0021.Figure 2.

Evaluation Kit User GuideUG-041THE ADuC WINDOWS SERIAL DOWNLOADERThe Windows serial downloader (WSD) is a Windows softwareprogram that allows a user to serially download standard IntelHEX files created by the ASM51 assembler to the MicroConverter via the serial port. The standard Intel HEX file isdownloaded into the on-chip Flash/EE program memory viaa selected PC serial port (COM1 to COM32). The WSD alsoincorporates the protocols for downloading to Flash/EE datamemory and for setting security bits and various run options.DOWNLOADING USING THE WSDFrom the Windows Serial Downloader window1.2.Click Download.Open the file at C:\ADuC\Download\DEMOCODE.HEX.1.2.3.Power up the evaluation board using the 9 V power supply.Connect the evaluation board header, J4, to your PCCOM1 serial port using the RS-232 dongle cable provided.The PC serial COM port can be changed from COM1 viathe WSD configuration option.Place the MicroConverter into serial download mode.a. To enter serial download mode on the ADuC814,connect S3 into the DLOAD/DEBUG position andpress the RESET switch.b. To enter serial download mode on any of theother ADuC8xx products, hold down the SERIALDOWNLOAD switch, and press and release theRESET switch.From the Start menu, choose Programs ADuC WSD.This launches the Windows serial downloader application.The WSD executable, provided on the CD, is located atC:\ADuC\Download\WSD.exe.The WSD automatically sends the reset command to theMicroConverter. If the MicroConverter is in serial downloadmode and the communications between the PC and theevaluation board are set up correctly, the WSD should displayADuC8xx version 2.Y above the top right corner ofthe Status box.08412-004OPENING THE WINDOWS SERIAL DOWNLOADERFigure 4. Open WindowWhile the file is downloading, a progress bar appears indicatinghow much of the file has been downloaded.After the file has been successfully downloaded, the progressbar disappears and the Status box is updated with the messageDOWNLOADING CODE[C:\ADuC\Download\DEMOCODE.HEX]:.OKRUNNING THE DOWNLOADED FILERunning Using the WSDFrom the Windows Serial Downloader window, click Run.The Status box is updated with the messageRun OK!The program starts running from Address 0x0000; this isindicated by a flashing LED on the evaluation board.To perform additional downloads, repeat Step 2 in the Openingthe Windows Serial Downloader section and click Reset onthe Windows Serial Downloader window.Manual Run OptionPress the RESET switch on the evaluation board with theSERIAL DOWNLOAD switch released (for the ADuC814,switch S3 to the normal position).

Evaluation Kit User GuideUG-041TIMING CONSIDERATIONS WHEN DEBUGGINGOther timing considerations to keep in mind are as follows:As with other 8052-based parts, the watchdog on ADuC8xxparts is not stopped during debugging. This leads to unpredictable results when the watchdog timer times out. Duringinitial development, it is recommended that the watchdog timerbe left disabled. For final software, Analog Devices suggests thatyou include code similar to the code that follows. When debugging, place a breakpoint at the second line shown, andwhen this breakpoint is reached manually, using the debugger,change the value in cWdcon to 0x00 so that the watchdog doesnot start. This scheme ensures that the program is debugged asit will be placed in the field. The watchdog itself cannot bedebugged by the debugger.As with other 8052-based debuggers, the user should not haltthe ADuC8xx if the part is either in idle or power-downmode. When a break from either power saving modeoccurs, the debugger will not be able to regain control ofthe part and the debug interface will crash.The timers on the ADuC8xx are not stopped on a breakfrom emulation. They continue to run if left enabled whenbreaking from emulation. cWdcon 0xe2 ;//Place parameters for watchdog in variable cWdcon.WdWr(cWdcon);//Call assembly function to start watchdog. cWdcon:setbWDWRmovWDCON,r7//Assume interrupts not enabled.//Parameter cWdcon passed in r7.retRev.

UG-041Evaluation Kit User GuideTHE ADuC WASPThe Windows analog software program (WASP) is a generalapplication for all MicroConverter products that allows analysisof the analog performance of these parts. The WASP recognizeswhich MicroConverter the PC is communicating with beforeautomatically downloading the appropriate code.Clicking Next bypasses the download sequence and can be usedif the WASP code is already downloaded and running on theMicroConverter. To identify the MicroConverter for the WASPsoftware, select the appropriate MicroConverter from theMicroConverter Select option box and click Next.This section serves as a tutorial to introduce both the SARWASP (for SAR ADC parts ADuC812, ADuC814, ADuC831,ADuC832, ADuC841, ADuC842, and ADuC843) and theΣ-Δ WASP (for Σ-Δ ADC parts ADuC816, ADuC824, ADuC834,ADuC836, ADuC845, ADuC847, and ADuC848). The termsSAR WASP and Σ-Δ WASP relate to the same WASP software.The software differentiates between the different products.SAR WASPAfter downloading the appropriate code, the WASP launches anacquisition window. This allows the user to configure, control,and analyze the ADC noise performance with the variousanalog and digital peripherals enabled/disabled.3.4.From this acquisition window, you can Select the channel for converting Set up the ADC conversion time and sampling parameters Select the number of samples to acquire Set up voltages on the DAC channels Select the use of the internal reference or an externalreference device Enable/disable various analog/digital peripheralsFigure 18 shows an example for converting on the temperaturesensor using the internal reference as displayed. Using theexample parameters shown, click Run. The acquired ADCsamples appear on the chart as shown in the bottom portion ofthe window for the ADuC812.08412-0182.Power up the evaluation board using the 9 V power supply.Connect the evaluation board to the COM1 serial port ofyour PC using the RS-232 dongle cable connected to the4-way header, J4.Place the MicroConverter into serial download mode asdescribed in the Opening the Windows Serial Downloadersection.From the Start menu, choose Programs ADuC WASP.This launches the WASP application.
