Cov chaw tsim tshuaj oscilloscope DSO138 tsis tso nws cov neeg siv thiab ib ntus hloov kho cov software ("firmware") rau lawv cov khoom siv. Cia peb pom cov kauj ruam twg koj yuav tsum mus los txhawm rau hloov kho firmware ntawm DSO138 oscilloscope.
Tsim nyog
- - oscilloscope DSO138;
- - USB-TTL (UART) hloov ua lwm yam.
Cov Lus Qhia
Kauj ruam 1
Thaum lub oscilloscope tig, nws cov zaub ua rau pom lub cim ntawm qhov tam sim no firmware version. Cov firmware version tau teev nyob tom qab cov tsiaj ntawv FW (FirmWare). Cia peb nco qab tus lej no.
Tam sim no peb mus rau nplooj ntawv nrog firmware ntawm lub official lub vev xaib ntawm cov chaw tsim khoom ntawm oscilloscope ntawm DSO138 thiab pom tias qhov twg ntawm lub firmware yog qhov tseeb. Thaum lub sijhawm sau no, tsab xov xwm tshiab yog 113-13801-061 hnub tim 2016-10-10. Qhov no yog kom meej meej tshiab tshaj li qhov ntsia oscilloscope firmware los ntawm daim duab dhau los.
Rub lub archive nrog lub khoos phis tawm thiab muab nws khaws cia rau qhov chaw tsis zoo ntawm koj lub hard drive. Cov firmware nws tus kheej yog cov ntawv nrog *. HEX txuas ntxiv. Hauv qhov no, "113-13801-061.hex".
Kauj ruam 2
Txhawm rau thauj cov firmware mus rau hauv lub cim ntawm DSO138 oscilloscope, koj xav tau ib txoj haujlwm tshwj xeeb. Cov oscilloscope tsim tawm pom zoo rau ST Flash Loader Tus Kws Qhia Tawm, uas tuaj yeem rub tawm los ntawm cov vev xaib raug cai (txuas hauv qab). Txhawm rau rub tawm qhov program, koj yuav tsum tso npe rau ntawm lub xaib. Tom qab ntawd, qhov txuas los rub tawm qhov program yuav xa rau xa ntawv.
Cov program no faib ua qhov khaws tseg. Rub tawm qhov program. Ntim nws rau koj lub computer thiab khiav cov installer. Tsis muaj subtleties, txhua yam yog tus qauv ntawm no.
Kauj ruam 3
Muaj me ntsis ntxiv ua haujlwm ua ntej txuas cov oscilloscope rau koj lub khoos phis tawm. Nws yog qhov yuav tsum tau kaw lub JP1 thiab JP2 cov neeg dhia dhia nyob hauv qab ntawm oscilloscope board. Qhov no yuav muab cov oscilloscope maub los rau hauv bootloader hom hloov chaw sib tham tsis tu ncua. Lub jumpers yuav tau txuas nrog los ntawm soldering.
Kauj ruam 4
Txhawm rau thauj cov firmware rau hauv oscilloscope lub cim xeeb, J5 (UART) chaw nres nkoj nrog cov qib ntsuas ntawm 3, 3 V yog siv. Yuav kom txuas nws rau lub khoos phis tawm, peb xav tau USB rau UART hloov. Cov cuab yeej zoo li no raug nqi kwv yees li 150 rubles hauv khw muag khoom hauv online.
Peb txuas rau "xuav" rau oscilloscope raws li daim duab. Nco ntsoov tias TX chaw nres nkoj ntawm lub hloov khoom siv (tso zis) yuav tsum txuas nrog RX (tswv yim) chaw nres nkoj ntawm oscilloscope, thiab rov ua haujlwm dua. Thiab GND yog cov hlau siv ntau. Tam sim no koj tuaj yeem txuas lub hloov mus rau USB chaw nres nkoj ntawm koj lub computer.
Kauj ruam 5
Peb qhib lub oscilloscope rau lub network, thiab txuas lub USB-UART hloov mus rau USB chaw nres nkoj ntawm lub computer. Tam sim no peb pib tsim Flash Flash Cov Ntsuas Ua Kom Tau Cov Kev Kawm.
Peb xaiv qhov chaw nres nkoj, tus naj npawb ntawm COM chaw nres nkoj uas lub hloov pauv txuas nrog. Tus so ntawm lub chaw tuaj yeem raug tso rau thaum uas lawv. Nyem rau "Tom ntej" khawm.
Qhov no yog ua raws li kev ceeb toom ntxiv hais tias kev txiav txim ntxiv yuav lwv oscilloscope nco. Nyem "Tshem tawm kev tiv thaiv" khawm los mus rau kauj ruam tom ntej.
Kauj Ruam 6
Tom qab ntawd, ib nplooj ntawv nrog cov ntaub ntawv hais txog qhov nco ntu ntawm oscilloscope qhib. Peb xaiv ntawm no nco nrog qhov loj me ntawm 64K (xyuas tias hauv lub kauj ruam dhau los nws tau txhais nrog raws nraim qhov loj me no). Nyem “Tom ntej”.
Khij lub thawv tom ntej “Download to device”. Nias lub khawm nrog peb dots los xaiv cov ntaub ntawv rub tawm ua ntej lawm "113-13801-061.hex". Tus so ntawm cov tsis xws luag tau teeb tsa hauv daim duab.
Nias lub pob "Next" yuav pib txheej txheem teeb nyem flasho ntawm DSO138 oscilloscope. Tom qab nws, txoj kev los ntawm kev kuaj lub downloaded firmware yuav pib. Kev ua tiav tiav yuav qhia los ntawm kev txhim kho ntsuab. Tag nrho cov txheej txheem yuav siv sijhawm li 1-2 feeb.
Kauj Ruam 7
De-energize lub oscilloscope. Disconnect UART converter los ntawm nws.
Tsis txhob hnov qab rau unsolder cov neeg kaw lub tsev JP1 thiab JP2.
Tam sim no koj tuaj yeem txuas cov oscilloscope rau lub network thiab xyuas kom tseeb tias cov ntawv tau hloov kho thaum thau khoom: "FW: 113-13801-061".
