Limitations with Express PSoC Express v2.1 build number CMX21_EP1 build installed displayed "Help, About." box. check build number Express check PSoC Express installation directory file called "Express1.txt". 7-Segment Multi-digit display drivers always automatically assign, user-assignment always remembered from build-to-build. Always confirm assignment manually when performing build. Automatic assignment CapSense drivers sometimes fail. Manually check assignment each build. "property" drivers, case CapSense, simulation widget shown with NaN. Interface Valuators (writeable registers) included design, Read-Only registers become writeable. prevent this, always single interface valuator. There problem with TableLookup transfer functions container (multi-element) inputs. Priority Encoder workaround. Limitations with PSoC Express v2.1
NOTE: Designs built with version compatible with version 2.1.
possible that projects created with version completely compatible. When working with projects created previous versions PSoC Express, recommended that work with copies projects. Build design fresh version rather than attempt migrate from earlier version. PSoC Express single compile engine, which prevents multiple simultaneous "Build" operations. attempt "Build" more than PSoC Express project time (although more than project/instance open time). prefix "pse_" string (two underscores with intervening characters) allowed object names. these object names, program prevents from completing step until remove offending entity from name. reserved words name objects. Reserved words are: C-Language reserved words, PSoC Express reserved words state names defined design (under user control). undetected GUI, this results build error, indicating offending name error messages. PSoC Express automatically detects needed hardware resources matches appropriate PSoC device when "Build" selected. However, resource manager cannot detect when exceeded. build error occurs, build project largest PSoC device ROM) order isolate this possibility. resource manager also cannot determine whether PSoC device adequate

internal lines between hardware resources. initial automatic assignment fails, build project next larger PSoC device number pins) within same family order isolate this possibility. User assignment requires PSoC Express code generation engine auto-place route functional blocks within PSoC device. order pins assigned manually combination functions sometimes make assignment fail. workaround which drivers getting assigned (what type). Drag drivers pins. Place drivers that initially assigned. Auto-place remaining drivers. experience difficulty assigning pins, that part shown does have enough pins enough internal lines functions. (External Watchdog drivers when used large number conjunction with Tachometer drivers show this tendency particular). workaround, choose either another device with more pins from same family device from family with more pins more resources (higher part number). PSoC Programmer installed does appear when "Program" selected appears disappears, remove connected PSoC programming devices from computer then re-connect them. PSoC Programmer still operating, shutdown computer restart. valid project must consist least input output device. project consisting interface drivers and/or valuators only will correctly build. input output then choose "Build." When transfer function references discrete states owned other objects (LED with OFF, example), transfer function should always named states when setting state comparing current state. This ensures portability design regardless particular device's property setting. Additionally, simulation following (Input_1) Then does work properly JavaScript characteristics. generated PSoC firmware performs expected, according language rules, simulation does reflect this behavior. ensure simulation results consistent with generated code performance, explicit comparisons with object's named states (select Expression Assistant" dialog that supports expressions complete list names). Some devices must selected instantiated (select catalog click property settings available (Tachometer inputs example). expected choices when selecting device, complete catalog selection (click then right-mouse-click choose "Properties" complete property list. When defining custom states Valuator Output Driver, have first define states, save transfer function then choose edit order states visible Expression Assistant. Stimulus file inputs range checked shown numerically entered simulation widget, graphical widget position bound driver's range. user's responsibility ensure proper input range within stimulus file.

Simulation PSoC Express implemented with JavaScript. Boolean expressions, such (Input_1 33), cannot themselves assigned output JavaScript. poor design practice this, even firmware, lead avoidable bugs. Expressions perform range checking signed integer values, limiting them from -32767 32767. Octal values (0777, instance) hexadecimal values (0x4343, instance) range checked valid bits. They truncated PSoC firmware (but simulation does truncate them). Expressions contain valid 16-bit signed integer "-32768," because application prevents alternative enter "0x8000," which equal "-32768" bit. Byte values promoted integer type math operations which types expression byte. least Continuous type Valuator (16-bit signed integer) must used prevent overflow arithmetic operations. Designs with complex combinatorial expressions experience Build failures long line lengths handled correctly compiler parser. solution split complex involved combinational logic lines into multiple lines (Status Encoder Transfer Function well suited this). conversion utility Schematic report requires installation Java Runtime engine. Follow prompts during first-time execution "Print PDF" install JRE. conversion operation trigger warning from computer's antivirus software agent. Enable script during this operation conversion will succeed. schematic entries associated with master (LM75, Slave instances) will have required pull-up resistors missing from note appears schematic indicating need pull-up resistors value required). Interface Valuators allow input from outside system explicitly range checked/limited. include these your system input Table Lookup Transfer Function, cause random behavior. Instead, define another Valuator define Transfer Function perform range checking limiting. Simulation Firmware match exactly with respect integer math results. JavaScript performs floating point math PSoC firmware performs strict integer math. simulation guideline integer math results. computers containing Microsoft Office 2003 SP1, some driver data sheets display dotted lines areas that should show text.

Known PSoC Express v2.1 Bugs Opening PSoC Express project PSoC Designer redirects PSoC Designer PSoC Express user module database. This cause user modules normally seen PSoC Designer look behave differently (including missing data sheets). redirection ensures that project generated PSoC Express provides consistent firmware/hex file results whether built PSoC Express PSoC Designer. PSoC Express currently allows explicit expression assignments appear transfer function definitions. Writing explicit assignments within transfer function definitions deprecated because these assignments create bugs that difficult find, they violate spirit intent transfer function programming model. This "loophole" closed future revisions PSoC Express. explicit expression assignment desired, program this operation custom.c. project contains custom.c customizations, build fail with following error message last line custom.c blank line: RefreshBOMTab sPinsDOM empty. project reports will generated. workaround carriage return custom.c. transfer function report portion project data sheet does know difference between 1-line status encoder transfer functions 1-line priority encoder transfer functions. Both types transfer functions listed status encoder transfer function report. driver catalog (Input, Output, Interface) open selection, user switches applications (via Alt-Tab), PSoC Express hangs, must close using Windows Task Manager. Default values specified driver (shown initial value) matching value specified driver source file (.cmx). User entered initial values accepted correctly. table lookup transfer function that large number output states sized that fits window. This makes table text very small. 4-digit 7-Segment Temperature 7-Segment drivers display incomplete leading zeroes when Position Decimal Point property NONE. With other settings, leading zeroes displayed. Temperature 7-Segment driver displays value 0.00 without .00. non-configurable Initial Condition property InternalPulledUp Banked Input driver shown driver data sheet. value actually High. nonconfigurable Initial Condition property InternalPulledDown Banked Input driver shown High driver data sheet. value actually Low. State Machine valuator allows usage keywords state transition names. This fixed future revisions PSoC Express.

When creating driver, driver name allowed contain double underscore characters. driver renaming function allows driver name contain this character combination. Renaming drivers with names containing double underscores deprecated this "loophole" will closed future revisions PSoC Express.
