Ob peb xyoos dhau los kuv tau paub nrog Lavxias teb sab microcontrollers los ntawm Milander. Nws yog xyoo 2013, thaum cov kws tsim khoom siv zog sib tham txog thawj qhov txiaj ntsig ntawm Tsoom Fwv Teb Chaws Lub Hom Phiaj Kev Pabcuam "Kev Txhim Kho ntawm cov khoom siv hluav taws xob thiab xov tooj cua hluav taws xob" rau xyoo 2008-2015. Lub sijhawm ntawd, K1986BE9x maub los (Cortex-M3 core) twb tau tso tawm, thiab 1986BE1T maub los (Cortex-M1 core) nyuam qhuav tshwm sim. Hauv cov ntaub ntawv yas, LQFP-144, nws muaj lub npe K1986BE1QI (aviation) hauv cov ntaub ntawv, thiab ntawm lub nti nws tus kheej lub npe MDR32F1QI. Ntawm cov chaw tsim khoom lub vev xaib nws muaj cov lus "avia", txij li nws muaj kev cuam tshuam tshwj xeeb rau kev lag luam dav hlau (ARINC 429, MIL_STD_1553).
Kuj ceeb tias, thaum lub sijhawm faib cov tswj hwm no, lub tuam txhab Milander tau npaj cov khoom siv debugging thiab lub tsev qiv ntawv ntawm cov txheej txheem rau kev ua haujlwm nrog cov khoom siv, "tab sis tsis muaj kev lav phib xaub lossis kev lav phib xaub txog qhov raug ntawm lub tsev qiv ntawv."

Microcircuits hauv rooj plaub yas rau pej xeem siv yog pheej yig dua, tab sis lawv tsis muaj los ntawm cov neeg muag khoom nrov. Tsis tas li ntawd, qhov zoo ntawm microcircuits nyob rau hauv rooj plaub yas, zoo li kuv, yog qhov phem tshaj "kub" sawv daws yuav. Piv txwv li, kuv tsis tuaj yeem khiav K1986BE1QI maub los ntawm 128 MHz yam tsis tau nce qhov flash latency parameter. Nyob rau tib lub sijhawm, qhov ntsuas kub ntawm qhov ntsuas no tau nce mus rau 40-50C. Tab sis 1986BE1T ("kub") maub los pib ntawm 128 MHz yam tsis muaj kev teeb tsa ntxiv thiab tseem txias. Nws yeej zoo.

Hauv Milandra lub vev xaib koj tuaj yeem pom txaus series 1986BE9 (Cortex-M3 core), tab sis rau K1986BE1QI (aviation) microcontroller kuv tsis pom dab tsi nyob ntawd. Tom qab saib cov ntaub ntawv, phau ntawv qhia thiab chaw ua haujlwm rau cov tsev kawm ntawv qib siab uas tau luam tawm nyob rau ntawd, kuv zoo siab tias cov neeg ua haujlwm tau raug cob qhia thoob plaws hauv lub tebchaws los ua haujlwm nrog cov tswj hwm Lavxias. Cov ntaub ntawv qhia feem ntau npaj rau kev ua haujlwm nrog I / O chaw nres nkoj, timers, ADC, DAC, SPI, UART. Ntau qhov kev tsim kho IDE yog siv (Keil, IAR, CodeMaster). Qee qhov lawv siv CMSIS cov npe, thiab qhov chaw lawv siv MDR Library. Cov peev txheej yuav tsum tau hais , uas muaj ntau cov lus los ntawm kev xyaum programmers. Thiab, ntawm chav kawm, peb yuav tsum tsis txhob hnov ββqab txog .
Xav txog MilandraMicroelectronics tab tom tsim nyob rau hauv Russia, thiab lub tuam txhab Milander ua lub luag haujlwm tseem ceeb hauv cov txheej txheem no. Cov tshiab nthuav microcontrollers tau tshwm sim, piv txwv li, 1986BE81T thiab Elektrosila nrog SpaceWire thiab MKIO interfaces (tib yam li xyoo 1986BE1 thiab, tejzaum nws, nrog cov teeb meem tib yam), thiab lwm yam. Tab sis cov tub ntxhais kawm zoo tib yam, cov kws qhia ntawv thiab cov engineers hauv pej xeem tsis tuaj yeem yuav cov microcircuits. Qhov no txhais tau hais tias lub zej zog engineering yuav tsis tuaj yeem txheeb xyuas qhov yuam kev thiab teeb meem nrog lub nti no. Nws zoo nkaus li kuv tias thawj zaug nws yog qhov tsim nyog los tsim cov microcircuits hauv cov ntaub ntawv yas, faib rau txhua tus neeg nyiam, thiab tom qab kev pom zoo (Latin approbatio - kev pom zoo, kev lees paub) los ntawm cov kws tshaj lij, lawv tuaj yeem npaj kho dua tshiab hauv rooj plaub hlau-ceramic nrog. kev tiv thaiv los ntawm txhua yam txaus ntshai. Kuv vam tias yav tom ntej no peb txhua tus yuav txaus siab rau cov haujlwm tshiab tshaj tawm ntawm kev nthuav qhia.
Lub rooj sib tham debug kuv tsim tuaj yeem rov ua dua, hloov kho thiab siv los ntawm leej twg hauv txoj kev kawm. Ua ntej tshaj plaws, kuv tau ua lub rooj tsavxwm rau kuv tus kheej, tab sis nws tau tig tawm zoo li ntawd .
K1986BE1QI (cua) yog tus tswj hwm zoo heev nrog cov kev sib txuas tshwj xeeb uas tuaj yeem siv hauv tsev kawm qib siab los qhia cov tub ntxhais kawm. Kuv xav tias tom qab kho qhov yuam kev uas tau teev tseg hauv tus maub los thiab dhau qhov kev xeem ntawv pov thawj, tus maub los yuav ya hauv qhov tseeb ntawm lo lus!
