I-STMicroelectronics STNRG328S Isilawuli Sokushintsha Isilawuli Sedijithali

Isingeniso

• Lo mbhalo uchaza inqubo yokuhlela kabusha inkumbulo ye-EEPROM yedivayisi ye-STNRG328S efakwe emabhodini ane-STC/HSTC topology. Inqubo ibandakanya ukulanda kanambambili file stsw-stc ngefomethi ye-hex usebenzisa i-adaptha yekhebula le-USB/TTL-RS232.
• I-example ngezansi ikhombisa ibhodi eline-STC topology kanye ne-STNRG328S egxunyekiwe. Idizayini isuselwe ezingxenyeni ze-X7R
  (shintsha ama-capacitor nama-resonant inductors) ngokuguqulwa kwesilinganiso esingu-4:1 (kusuka ku-48 V ibhasi lokufaka ukuya ku-12 V Vout), ekwazi ukuletha amandla angu-1 kW ezinhlelweni zeseva.

  

• Ikhodi kanambambili ethi stsw-stc ingalandwa kusukela kusixhumanisi esithi https://www.st.com/en/product/stnrg328s. I-stsw-stc isekela ukuxhumana kwe-PMBUS. Ungathola uhlu lwemiyalo nolwazi olwengeziwe mayelana nedivayisi endaweni efanayo.
  Okubalulekile: Xhumana nehhovisi lezokuthengisa lasendaweni lapho uhlela i-chip okokuqala ngqa.

Amathuluzi nezinsimbi

Amathuluzi namathuluzi adingekayo ukuze kwenziwe inqubo yokuthuthukisa kuchazwe ngezansi.

1. Ikhompyutha yomuntu siqu enezidingo ezilandelayo:
   • Windows XP, Windows 7 amasistimu wokusebenza
   • okungenani inkumbulo engu-2 GB ye-RAM
   • Imbobo ye-USB engu-1
2. Ukufakwa file I-CDM v2.12.00 WHQL Certified.exe yomshayeli we-FTDI we-USB 2.0 kuya kusiguquli se-UART se-serial. I file ingalandwa ku-ST.com ekhasini lethuluzi lokuhlola le-STEVAL-ILL077V1 kuhla lwemibhalo olungaphansi lwe-STSW-ILL077FW_SerialLoader.
   • Xhuma ikhebula le-USB/UART ku-PC nakubhodi lomama. Isikhathi sokuqala lapho ikhebula lixhunywa ku-PC, umshayeli we-FTDI USB serial converter kufanele atholwe futhi afakwe ngokuzenzakalelayo.
     Uma umshayeli engafakiwe, qalisa ukufakwa file I-CDM v2.12.00 WHQL Certified.exe.
   • Uma umshayeli esefakiwe, ukuxhumana ngembobo ye-USB kuhlelwa ku-PC yangaphakathi COM. Imephu ingaqinisekiswa kusiphathi Sedivayisi ye-Windows: [Iphaneli Yokulawula]>[Isistimu]>[Isiphathi Sedivayisi]>[Izimbobo].

     
3. Faka kungobo yomlando file I-Flash Loader Demonstrator.7z, edingekayo ukuze ufake i-ST serial flash loader ku-PC.
   I file ingalandwa ku-ST.com ekhasini lethuluzi lokuhlola le-STEVAL-ILL077V1 kuhla lwemibhalo olungaphansi lwe-STSW-ILL077FW_SerialLoader.
   • Ngemva kokufaka i-toolset, sebenzisa i-executable file STFlashLoader.exe. Isikrini esiboniswe esithombeni esingezansi sizovela.

     
4. I-.hex kanambambili file ihlanganiswe ne-IAR Embedded Workbench. Idivayisi esebhodini kufanele isivele ikhanyisiwe nge-firmware enosekelo lokuxhumana lwe-PMBUS. Nge-firmware, sibhekisela ku-STUniversalCode.
5. Intambo ye-Micro USB.
6. Ukunikezwa kukagesi kwe-DC ukuze kusebenze ibhodi.

Ukusethwa kwezingxenyekazi zekhompuyutha

Lesi sigaba sichaza ukuxhumana phakathi kwekhebuli ye-UART namaphinikhodi wedivayisi. Iphinikhodi yedivayisi iboniswa ngezansi:

1. Setha izikhonkwane njengoba kushiwo kuthebula elilandelayo:
   Ithebula 1. STNRG328S izilungiselelo zephini
   

   Ireferensi ye-Jumper	Setha isikhundla
   I-Pin 13 (VDDA)	I-+3.3V / +5V ebhodini inikeziwe
   I-PIN 29 VDD	I-+3.3V / +5V ebhodini inikeziwe
   Iphinikhodi 1 (UART_RX)	Setha ku-UART TX yekhebula
   I-Pin 32 (UART_TX)	Setha ku-UART RX yekhebuli
   I-Pin 30 (VSS)	GND
   I-Pin 7 (UART2_RX)	Xhuma emhlabathini ukuze ukhubaze i-bootloader ku-UART yesibili

2. Xhuma isiphetho se-USB sekhebula le-adaptha embobeni ye-USB yePC; bese uxhuma isiphetho se-serial ngezixhumi zephinikhodi zesokhethi.
   Qinisekisa ukuxhumana okulandelayo:
   • RX_cable = TX_devive (Pin 32)
   • TX_cable = RX_device (Pini 1)
   • GND_cable = GND_device (Pin 30)
     Enye i-UART RX Pin 7 ye-STNRG328S kufanele ixhunywe phansi.

     

Ilanda i-firmware

• Ngokuhlelwa kabusha kwememori ye-EEPROM yedivayisi ye-STNRG328S, sizobhekisela ebhodini le-X7R-1kW eliboniswe kuMfanekiso 1.
• I-firmware ye-stsw-stc ibhekwa njengesivele ifakiwe.
• Ibhodi isebenzisa i-Pin 1 kanye ne-Pin 32 njenge-UART. I-firmware ilungiselela lezi zikhonkwane ze-I2C ezabiwe njenge-UART ngoba idinga ukunika amandla i-bootloader nge-UART. Lesi sici singenziwa sisebenze ngokukhipha umyalo wokubhala we-PMBUS ukuze usethe inani le-0xDE libe ngu-0x0001.
• Ukuze uthumele imiyalo ye-PMBUS, umsebenzisi udinga i-GUI nesixhumi esibonakalayo sehadiwe i-USB/UART (bona 1.).
• Ngemva kokusebenzisa lo myalo, xhuma ikhebula le-UART ku-Pin 1 kanye ne-Pin 32 njengoba kuchazwe ngenhla bese ulandela izinyathelo ezingezansi:

1. Qalisa i-STFlashLoader.exe, iwindi elingezansi liyaboniswa.

   

   • Sebenzisa izilungiselelo eziboniswe emfanekisweni ongenhla.
     Okubalulekile:
     Ungachofozi inkinobho ethi [Okulandelayo] ngokushesha njengoba kungase kuvale iwindi lesikhathi. Okunye ukusetha kabusha iphinikhodi kuyadingeka ngaphambi kokuqhubeka.
   • Ku-[Igama Lembobo], khetha imbobo ye-COM ehlotshaniswa ne-USB/Serial converter. Isiphathi Sedivayisi ye-Windows ku-PC yomsebenzisi sibonisa imephu yembobo ye-COM (bona Amathuluzi namathuluzi).
2. Vala ibhodi futhi UVULA futhi ngokushesha (ngaphansi kuka-1 s) cindezela inkinobho ethi [Okulandelayo] esithombeni esingenhla. Isikrini esilandelayo sizovela uma ukuxhumana okuphumelelayo phakathi kwe-PC nebhodi sekusungulwe.

   

3. Kusuka ebhokisini lengxoxo esithombeni esingenhla, khetha i-STNRG ohlwini [Lokuqondisiwe]. Kuzovela iwindi elisha elinemephu yememori yememori engaguquguquki.

   

4. Chofoza inkinobho ethi [Okulandelayo], futhi isithombe esingezansi sizovela.
   Ukuze uhlele i-EEPROM:
   1. khetha [Landa kudivayisi]
   2. ku- [Landa ku- file], phequlula ku- file ukulanda kumemori ye-SNRG328S.
   3.  khetha inketho ye-[Global Erase].

      

5. Chofoza okuthi [Okulandelayo] ukuze uqale inqubo yokulanda.
   Lindela inqubo yokuhlela ukuthi iqede futhi uqinisekise ukuthi umlayezo wempumelelo ngoluhlaza uyavela, njengoba kukhonjisiwe esithombeni esingezansi.

   

6. Ungaqinisekisa ukuthi unambambili olungile ulandiwe ngokuhlola ukuthi idatha nekhodi yokuhlola i-firmware ifana nokukhishwa.
   Le nqubo ichazwa ku-STC Checksum Implemetation.docx etholakala ku-ST.com.
