Mbali ndi Ubwino

Mapologalamu a in-system amalola kukonza ndi kukonzanso zida za ISP zitayikidwa pa Printed Circuit Boards (PCBs). Izi zimachotsa gawo lowonjezera lothandizira lomwe limafunikira popanga kupanga zida zopangira zida zakunja zisanayikidwe pa PCBs. Kuchotsa izi kumachepetsa kuthekera kowononga zotsogola zosalimba za zida zokwera pamapini apamwamba kapena kuwononga chipangizocho kudzera mu electrostatic discharge (ESD) panthawi ya pulogalamu. ISP imalolanso ogwiritsa ntchito kusintha kapangidwe kake ndikukweza kumunda popanda kuchotsa zida za ISP ku PCBs. Kuphatikiza apo, imalolanso kugwiritsa ntchito makina ophatikizika a microcontroller kapena tester in-circuit kuti achite ntchito zamapulogalamu pazida za ISP ndikuphatikiza madongosolo amapulogalamuwa pakupanga ma board ozungulira.

In-System Programming Systems

Zigawo zitatu zofunika za ISP system ya ATF15xx CPLDs ndi:

Mapulogalamu

Kukhazikitsa algorithm yamapulogalamu, komanso m'badwo wa JTAG malangizo ndi zidziwitso za zida za ISP zomwe mukufuna. Izi zitha kukhala pulogalamu yamapulogalamu yomwe imagwira pa PC, chowongolera chophatikizika, kapena zida zoyesera zozungulira.

Ma ATF15xx CPLD amatha kukonzedwa pagulu loyang'anira dera kudzera pa JTAG mawonekedwe panthawi yoyesa bolodi la dera pogwiritsa ntchito tester in-circuit. Kawirikawiri, SVF file opangidwa ndi ATMISP ayenera kukhala ndi zonse zofunikira za JTAG zidziwitso zamadongosolo a in-system zomwe oyesa ma in-circuit testers amayenera kukonza ma ATF15xx CPLD pa bolodi yoyang'anira dera. Njirayi imalola kuphatikizika kwa sitepe yopangira mapulogalamu muzoyesa stage ya kayendedwe ka kupanga.

JTAG ISP Interface

ISP ya ATF15xx CPLDs ikugwiritsidwa ntchito pogwiritsa ntchito IEEE 1149.1 Std. JTAG mawonekedwe. Mawonekedwewa atha kugwiritsidwa ntchito kufufuta, kukonza, ndikutsimikizira ma ATF15xx CPLD. The JTAG mawonekedwe ndi mawonekedwe a serial omwe ali ndi TCK, TMS, TDI, ndi TDO siginecha ndi J.TAG Wowongolera Test Access Port (TAP). Pini ya TCK ndiye kulowetsa kwa wotchi ya JTAG TAP controller ndikusintha mkati / kunja kwa JTAG malangizo ndi deta. Pini ya TDI ndiye kulowetsa kwa serial data. Amagwiritsidwa ntchito kusamutsa malangizo a pulogalamu ndi data mu zida za ISP. Pini ya TDO ndiye kutulutsa kwa data. Amagwiritsidwa ntchito kusamutsa deta kuchokera ku zida za ISP. Pini ya TMS ndi pini yosankha. Imalamulira dziko la JTAG TAP wolamulira. The JTAG mapini a mawonekedwe a ATF15xx CPLD pa board chandamale ya ISP akuyenera kulumikizidwa ndi zida za ISP (mwachitsanzo chingwe chotsitsa cha ISP) makamaka kudzera pamutu wa pini 10. ISP interface hardware ikufunikanso kulumikizidwa ndi PC yomwe ili ndi pulogalamu ya ISP. ISP interface hardware imakhazikitsa kulankhulana pakati pa mapulogalamu a ISP ndi zipangizo za ISP, ndipo imalola mapulogalamu a ISP kusamutsa malangizo a mapulogalamu ndi deta kuchokera pa PC yolandira kupita ku ATF15xx CPLDs. ATF15xx CPLDs ndi JTAG mawonekedwe othandizidwa ndi JTAG yogwirizana komanso imathandizira magwiridwe antchito ofunikira a Boundary Scan Test (BST) omwe afotokozedwa mu JTAG muyezo. Ma ATF15xx CPLD atha kukonzedwa kuti akhale gawo la JTAG BST chain ndi ena a JTAG zida zoyezera mozungulira pa board board. Ndi mbali iyi, ma ATF15xx CPLD amatha kuyesedwa pa board board pamodzi ndi ma JTAG-zida zothandizidwa popanda kugwiritsa ntchito kuyesa kwa bedi la misomali.

Chidziwitso cha chipangizo pambuyo pa kusokonezedwa kwa ISP:
- ISP ikasokonezedwa, mapini onse a I/O amatchulidwa katatu mosasamala kanthu za mabwalo a Pin-keeper.
- Imaletsa zida zokonzedwa pang'ono kuti zisayambitse mikangano yamabasi ndi zida zina pa board board.

Pamapulogalamu a ISP, zikhomo zonse za I/O zili mu imodzi mwamikhalidwe iyi:
- High-impedance state:
- Pamene chida chopanda kanthu/chofufutidwa chakonzedwa.
- Chidacho chikakonzedwanso ndi mabwalo a Pin-keeper atsekedwa.
- Imaletsa mikangano yamabasi ndi zida zakunja zolumikizana ndi ma ATF15xx CPLDs pa board board.
- Zatsatiridwa mofooka ku mkhalidwe wam'mbuyo:
- Chida chokonzedwanso chikakonzedwanso ndi mabwalo a Pin-keeper athandizidwa.
- Zikhomo za I/O zimasunga malingaliro am'mbuyomu asanafike ISP.
- Imaletsa ISP kusokoneza magwiridwe antchito a zida zina pa board board.

Kugwiritsa ntchito zambiri za JTAG maunyolo pa bolodi limodzi osavomerezeka.
- Zipangizo zimatha kulumikizana pakati pa mitundu yosiyanasiyana ya JTAG unyolo.
- Gululi limagwira ntchito pokhapokha zida zonse mu JTAG maunyolo amakonzedwa bwino.
- Ngati mapulogalamu alephera pa chipangizo chimodzi pa unyolo pomwe JTAG maunyolo adakonzedwa bwino:

Ngati ATMISP ili ndi vuto lolumikizana ndi JTAG Chipangizo cha hardware, yesani kuyendetsa Self Calibrate kapena Manually Calibrate kuti muchepetse ma frequency a J.TAG zizindikiro.
Onetsetsani kuti chingwe cha LED pa ATDH1150USB chatsegulidwa ndipo ndi chobiriwira pulogalamu isanayambe. Onetsetsani kuti chingwe chotsitsa cha ISP chikutha kulumikizana bwino ndi pulogalamu ya ATMISP.

Onetsetsani kuti VCC voltage imayikidwa pa chingwe cha ATDH1150USB.
- VCC yogwiritsidwa ntchito ndi chipangizo choyamba mu JTAG unyolo uyenera kuperekedwa ku chingwe cha ATDH1150USB kudzera pa pini 4 ya 10-pin J.TAG mutu.
- Kwa ma ATF15xx CPLD okhala ndi VCCINT ndi VCCIO, VCCIO iyenera kugwiritsidwa ntchito pa chingwe cha ATDH1150USB.
