Installation CHOOSE "REPAIR" OPTION WHEN INSTALLING ITEMS Install: computer with previous version PSoC Express, must first uninstall (the first execution installer version will automatically uninstall it). ensure complete clean uninstall, want check "PSoC Express" "Common" directories where have chosen install application delete leftover files AFTER uninstall process. After uninstall, execute version installer again install PSoC Express version 2.2.
Uninstall PSoC Express: uninstall PSoC Express, Express will also uninstalled. uninstall PSoC Express Express Pak, Execute "Add/Remove Programs" Windows Control Panel, find "PSoC Express" choose "Change/Remove." Uninstalling PSoC Express v2.1 will also uninstall Express Pak. PSoC tools must installed parallel each other (same disk, same directory). tools installed individually, must ensure that they directory, parallel each other. (The default created installers ./Program Files/Cypress MicroSystems/.). Limitations with PSoC Express v2.2
NOTE: Designs built with version compatible with version 2.2.
possible that projects created with version completely compatible. When working with projects created previous versions PSoC Express, recommended that work with copies projects. 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).
When "Build" selected, PSoC Express automatically detects needed hardware resources matches appropriate PSoC device. 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 interface driver. project consisting valuators only will correctly build. driver 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. your 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 them 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. Auto-assigned pins re-assigned PSoC Express unless move them least once. want lock auto-generated assignment, drag each back desired lock Currently, CapSense drivers will co-exist with other analog drivers. This will addressed future version.

Known PSoC Express v2.2 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. Making changes PSoC Express v2.2 project PSoC Designer v4.3, then saving project, will make PSoC Designer v4.3 PSoC Designer User Module database instead PSoC Express User Module database. This cause user modules look behave differently. Once this occurs project, PSoC Designer v4.3 will always treat PSoC Designer project. 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 cannot tell difference between 1-line status encoder transfer functions 1-line priority encoder transfer functions. Both types transfer functions listed status encoder transfer function report. table lookup transfer function that large number output states sized that fits window. This makes table text very small. Please zoom functions view small text. 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 .00. CapSense Slider will sometimes report slider position around center. Playing with property settings tune this problem away. WUSB Master driver initial state BIND because will stall approximately 20-25 seconds each time PSoC powers-up resets. During BIND, both slave master block foreground seconds waiting/looking bind. Future revision will remove this limitation.

When slave does have master will operate/respond more slowly input changes, because will look master every update loop. Future revision will remove this limitation. current version WUSB drivers will allow PSoC device both slave master. second radio, PSoC Express will display warning prevent second radio from being added. WUSB radio pins will assign when pins assigned. Once assigned, SHARED pins individually moved. Replacing remote monitor/slave driver will cause transfer function tear down. prevent this, pass-through if(1) then(itself) priority encoder before adding main system logic. pass-through transfer function will torn-down only. CapSense designs, possible exceed requirements before running pins (approximately sensors enabled). build will fail message will point CapSense. drivers that allow string label entered have specific length restrictions, described property comments datasheet, these programmatically enforced GUI. names long displays diagrams reports truncate names. this occurs, rename drivers shorter names. character constants like clause status priority encoder, javascript error occurs. only character constants THEN clause. Screens that have 16:9 aspect ratio display some dialog boxes with action buttons bottom blocked. There known workaround this. Certain drivers (CapSense WUSB) require parts complete implementation (the "properties" driver instance). Currently PSoC Express will alert forget needed second part. Builds will fail with very unclear error messages Windows option disable format names. When multi-value input driver (like dual axis accelerometer) into Point Region valuator, there indication which multiple values input. project datasheet also does call specific input. only workaround first assign multi-value input valuator (IF(1) THEN(multi-value input)) then feed valuator into Point Region. name length limit characters enforced when using multi-object rename tool. names will indicated long property changed individual rename attempted. project will build operate successfully either case.

Initial value property output driver value that driver will during first update loop, value assigned immediately power-up. some digital inputs this cause initial glitch power-up. Replacing continuous driver that input Point Region will cause existing setpoints scaled match range input. Using seven-segment single digit display input itself will cause run-time script error. data flow/association lines cannot hidden; they always displayed.
