rev. 2.0 10/10 copyright ? 2010 by silicon laboratories AN144 AN144 cp210 x /cp211 x d evice c ustomization g uide relevant devices ? this application note applies to the following devices: ? cp2101, cp2102, cp2103, cp2104, cp2105, cp2110, cp2112 1. introduction this document is intended for developers creating pro ducts based on the cp210x/cp211x usb bridge controllers. it provides information about obtaining a vendor id (vid ) and product id (pid) for a cp210x/cp211x product and describes the steps necessary for customizing the de vice descriptors contained in the cp210x/cp211x programmable area. refer to www.silabs.com for the latest revisions of this document and other application notes related to the cp210x/cp211x device families. 2. obtaining a vid and pid each device on a usb bus must have a unique vid, pid, and serial number combination. vendor ids are owned by the vendor company and assigned by the usb implementers forum (usb-if) only. details about obtaining a unique vid can be found at www.usb.org/developers/vendor . to obtain the right to license the usb-if logo, you must register your product's vid and pid with usb-if and submit your product to the usb-if compliance program. usb-if compliance program details are available at www.usb.org/developers/compliance . once your product is certified, you ca n add it to the usb-if integrators list, and you can also use the ?certified usb? logo on your product. if you do not wish to license the usb-if logo for your product, you can use the defa ult silicon laboratories vid along with a unique pid. to obtain a unique pi d for your cp210x/cp211x-based product, visit ? http://www.silabs.com/requestpid . having a unique pid reduces the chances that another device with the same vid, pid, and serial number w ill appear on the same usb bus. 3. customizing driver installati ons, cp210x custom setup utility ? (cp2101/2/3/4/5) the driver installation is customizable by modifying certain sections of the ha rdware installation files (.inf). the strings contained in the .inf files affe ct what is displayed in the ?found new hardware wizard ? dialogs, device manager, and the registry. refer to ?an220: u sb driver customizatio n? for more details. note: any changes to the windows ? installation .inf files will require new windows hardware quality labs (whql) tests.
AN144 2 rev. 2.0 4. customizing device descriptor s and other configurable options the descriptors and other configurable options of the devi ces in the cp210x/cp211x families are modifiable using the following windows programs. these programs are included in the software zip file in this application note. how to use these programs is described in more detail in the following sections. cp210xsetids uses the windows host ap i functions implemented by cp210xmanufacturing.dll . the host api functions give read/write access to the descriptors contained in progra mmable areas of a connected device. another option is implementing a custom application using the host api and cp210xmanufacturing.dll suited to the individual needs of a particular production environment. both cp2110setids and cp2112setids use the slabhiddevice.dll and the customization interface specified in their respective application notes, ?an433: cp2110 hi d to uart api specification? and ?an496: cp2112 hid usb to smbus api specification?. the descriptors can also be set in the factory at production time for large orders. contact your silicon laboratories sales representative for details. table 1. device customization programs device program cp2101/2/3/4/5 cp210xsetids.exe cp2110 cp2110setids.exe cp2112 cp2112setids.exe
AN144 rev. 2.0 3 4.1. customizing device descriptors using cp210xsetids.exe (cp2101/2/3/4/5) cp210xsetids.exe is an example program that uses the cp 210x host api functi ons implemented by cp210xmanufacturing.dll . the program window is shown in figure 1 . cp210xsetids.exe demonstrates the method of accessing and changing the descriptors cont ained in the connected device's programmable area. to use cp210xsetids.exe , it is necessary to have the devices connected and have the unmodified device drivers that shipped with the original cp210x kit inst alled. the customized devi ce driver installation files that contain the vid and pid values should also be installed. for informati on on creating customized dev ice drivers for the cp210x, refer to ?an220: usb driver customizat ion.? the default driver must be insta lled so that the cp210x device with the default factory settings appears in the device list. the customized driver s will be needed after the device ids have been changed and the cp210x device is reset. all cp210x devices are programmed in the same manner using the cp210xsetids.exe tool, but each parameter on the one-time-programmable (otp ) devices can only be programmed one time. the cp2101, cp2102, and cp2103 parameters can be reprogramm ed multiple times using the cp210xse tids.exe utility, but the cp2104 and cp2105 parameters can only be programmed once using the cp210xsetids.exe utilit y. after the cp2104 and cp2105 have been pr ogrammed once, the cp210xsetids.exe utility c an be run, but the ne w values will not be programmed into the device. before running cp210xsetids.exe , copy cp210xmanufacturing.dll into the \windows, \winnt, or \system32 directory, the directory containing the executable, or any directory in the ?path? environment variable. figure 1. cp210xsetids example application
AN144 4 rev. 2.0 when cp210xsetids.exe is launched, the program searches the windows registry for any cp210x devices attached to the pc. the full path information for all of th e devices found is inserted into the ?select device? drop- down list, and the first devic e is selected automatically. cp210xsetids.exe then queries information from the selected device using the cp210x host api functions and fills in the values for each of the seven selectable fields of the application. when a new device is selected from the list, the fields will be updated with in formation from the most recently selected device. to change one or more of the values, click on the checkbox to the left of the field and enter the new value. once the new values have been entered, click on the ?program device? button. the values entered are subject to the following limitations: 1. vid ?four hexadecimal digits. 2. pid ?four hexadecimal digits. 3. max. power ?two hexadecimal digits with maximum setting of 250 (the value is in 2 ma units). 4. serial number ?any sequence of up to 63 characters (c p2101/2/3/4) or 16 characters (cp2105). 5. product string ?any sequence of up to 126 characters (c p2101/2/3/4) or 47 characters (cp2105). 6. release version ?each field is a decimal number value 0?99. 7. flush buffers ?selects which buffers to empty upon the open and close events. applies to cp2104/5 devices only. 8. interface 0 and 1 strings ?any sequence of up to 32 characters. applies to cp2105 only. 9. device mode ?selects the operating mode for the enhanced a nd standard interfaces. applies to cp2105 only. notes: 1. avoid connecting more than one device containing the same vid, pid, and serial number combination. 2. when the serial number of a cp210x device is changed and the device is reset by calling the host api function cp210x_reset() , the device will reenumerate, and t he device driver will be installed. 3. the serial number and product string are automatica lly converted to unicode strings before programming.
