TEB CHAWS DOC

Yuav xa cov ntaub ntawv siv tus qauv pheej yig RF los ntawm USB. Lub voj voog tau txais lub zog los ntawm USB chaw nres nkoj (tuaj yeem muab 100mA thiab nrog qee qhov program koj tuaj yeem ncav cuag 500mA) Cov Khoom Siv: 1 - Ib khub ntawm RF module (zoo li Laipac RLP/TLP433A) saib tom qab nws hauv sparkfun.com (lawv muaj qhov sib txawv kev khiav hauj lwm zaus: 315, 433 thiab 917 (?) MHz) 1-TSUB3410-Serial-to-USB integrated chip (QFP-32) los ntawm Texas Instruments. 1 - Ib Lub Hwj Huam LED (koj tuaj yeem hla nws) 1 - 3.3V LDO (Tsawg Tso Tawm) tus tswj hwm - txuas rau hauv +5V (+/- 10%) kab los ntawm USB. Pib nrog phau ntawv qhia "walkthrough.pdf", tom qab nws peb yuav txhim kho cov wireless txuas kom txuas nrog USB chaw nres nkoj. ! ! ! - Altought nws yuav zoo li yooj yim Circuit (tsuas yog txuas RF), koj yuav pom qee pob zeb hauv koj txoj kev. Kuv tseem tsis paub yog tias qhov no yog ib qho kev ntseeg ruaj khov.. yog li ceev faj qhov twg koj yuav siv nws. Qhia kom sim cov Circuit no XWB Thaum koj nyob zoo lawm! yog tias tsis mus ua si PS2… txwv tsis pub qhov no tuaj yeem ua rau koj lub cev tsis muaj zog parasympathetic!

Kauj Ruam 1: Txheeb xyuas RF Modules

Ua ntej tshaj plaws koj yuav tsum ua raws nraim li cov theem sau hauv PDF ntawv txuas rau lub xaib no ("taug kev …")

Nws yog lub tswv yim zoo los tshuaj xyuas thawj cov qauv. Ua nws ntawm lub khob cij, nws ua haujlwm? Zoo, txav mus rau qib tom ntej… lossis txheeb xyuas kev sib txuas, xov hlau, khoom siv (koj puas tau qhib nws?). Koj tuaj yeem tshawb xyuas qhov txuas txuas nrog lub osciloscope lossis siv ib qho (hyper) davhlau ya nyob twg software. Txheeb xyuas qhov siab tshaj plaws baud tus nqi! (kuv 4800bps). Koj yuav xav tau MAX232 nti, nws yog Serial qib hloov pauv… [PC >> MAX232 >> TX] ~~~~~~~ cua ~~~~~~~~ [RX >> MAX232 >> PC] email rau kuv … tej zaum kuv tuaj yeem pab koj!

Kauj Ruam 2: Txhim Kho Txoj Kev Siv Hluav Taws Xob los Siv USB Hloov Chaw Serial

Txhim kho Circuit kom siv USB Hloov Chaw Serial
Txhim kho Circuit kom siv USB Hloov Chaw Serial

Yog tias koj muaj hmoo zoo li kuv, koj tuaj yeem siv Lub Tshuab Ceev Caj Npab Zoo li LPKF C-Series. Txoj kev no nws tso cai rau koj siv me ntsis nyuab dua SMD (Surface Mounted Devices) IC.

Tus Txais: Qee lub sij hawm tsis txaus ntseeg kom hloov roj teeb, yog li peb txiav txim siab muab tus txais los ntawm USB chaw nres nkoj. Nws yog qhov yooj yim heev, USB xa tawm +5V (+/- 10%), yog li qhov tsuas yog qhov koj yuav tsum tau ua yog txuas rau nws tus tswj hwm qhov hluav taws xob (siv Kev Tso Tawm Tsawg-Tawm Tawm yog lub tswv yim zoo). Txhawm rau cuam tshuam RF tus txais nrog USB peb tab tom siv TUSB3410 Serial-to-USB module. Nws yog ib qho yooj yim heev nti thiab koj yuav pom nws ntawm, yuav luag, txhua tus neeg muag khoom loj (?). Peb lub zog nws nrog 3.3V, tswj los ntawm USB chaw nres nkoj. (Tsis txhob hnov qab teeb tsa cov tsav tsheb uas koj tuaj yeem rub tawm los ntawm Texas Instruments lub vev xaib) Thaum kuv txuas Tus Txais Txais rau TUSB Kuv muaj teeb meem. Qhov Serial In chaw nres nkoj los ntawm TUSB3410 muaj qhov muaj zog rub tawm tus tiv thaiv, yog li txhua cov ntaub ntawv uas kuv tau txais yog nrog qhov pib ntawm 3.3V (saib sab hauv kev qhia sab hauv ntawm SIN chaw nres nkoj hauv cov ntaub ntawv …). Yog li peb tau ntsaws qhov nruab nrab ntawm tus txais thiab TUSB4310. Transmitter: Ncaj nraim mus! Tsuas yog ua raws cov txheej txheem yooj yim thiab nws yuav tsum ua haujlwm zoo kawg nkaus.
