Functional Safety Manual
A Functional Safety Manual yeMPLAB XC compilers inowanikwa mune zvinyorwa pasuru paunotenga rezinesi rekuchengetedza rinoshanda.
Component Rezinesi uye Mavhezheni
Maturusi eMPLAB® XC8 C Compiler yeAVR MCUs maturusi anonyorwa uye anoparadzirwa pasi peGNU General Public License (GPL) zvinoreva kuti kodhi yayakabva inogoverwa pachena uye inowanikwa kune veruzhinji. Iyo kodhi kodhi yezvishandiso pasi peGNU GPL inogona kutorwa yakaparadzana kubva kuMicrochip's website. Unogona kuverenga iyo GNU GPL mu file zita rakawanikwa iyo subdirectory yekuisa yako dhairekitori. Hurukuro huru yemisimboti iri pasi peGPL inogona kuwanikwa pano. Tsigiro kodhi yakapihwa yemusoro files, linker scripts, uye runtime raibhurari ndeye proprietary code uye haina kuvharwa pasi peGPL.
Iyi compiler ndeyekuitwa kweGCC vhezheni 5.4.0, binutils vhezheni 2.26, uye inoshandisa avr-libc vhezheni 2.0.0.
System Zvinodiwa
Iyo MPLAB XC8 C compiler uye software yerezenisi yainoshandisa inowanika kune akasiyana masisitimu anoshanda, kusanganisira 64-bit shanduro dzinotevera: Professional editions eMicrosoft Windows 10; Ubuntu 18.04; uye macOS 10.15.5. Mabhinari eWindows akasainwa kodhi. Mabhinari eMac OShave akasainwa kodhi uye notarized.
Kana iwe uchimhanyisa network rezinesi sevha, makomputa chete ane masisitimu anoshanda anotsigirwa nevakongiri anogona kushandiswa kubata rezinesi server. Nezve xclm vhezheni 2.0, sevha yerezinesi retiweki inogona kuisirwa paMicrosoft Windows Server papuratifomu, asi sevha yerezinesi haidi kumhanya pane server vhezheni yeiyo inoshanda sisitimu.
Midziyo Inotsigirwa
Iyi compiler inotsigira ese 8-bit AVR MCU zvishandiso zvinozivikanwa panguva yekuburitswa. Ona (mune dhairekitori rekodhi rekodhi) yerondedzero yemidziyo yese inotsigirwa. Izvi files zvakare nyora zvigadziriso zvishoma zvechigadzirwa chimwe nechimwe.
Zvinyorwa uye Kukwidziridzwa kweRezinesi
Iyo MPLAB XC8 compiler inogona kuitwa seine rezinesi (PRO) kana isina rezinesi (Yemahara) chigadzirwa. Iwe unofanirwa kutenga kiyi yekushandisa kuti uwane rezenisi compiler yako. Rezinesi rinobvumira mwero wepamusoro wekugadzirisa zvichienzaniswa neChigadzirwa Chemahara. Iyo compiler isina rezenisi inogona kushanda zvachose isina rezinesi.
An MPLAB XC8 Functional Safety compiler inofanirwa kuitwa activated ine functional security rezinesi yakatengwa kubva kuMicrochip. Iyo compiler haishande isina rezinesi iri. Kana yangoitwa, iwe unogona kusarudza chero optimization level uye shandisa ese compiler maficha. Uku kuburitswa kweMPLAB XC Functional Safety Compiler inotsigira Network Server License.
Ona Kuisa uye Kupa Marezenisi MPLAB XC C Compilers (DS50002059) gwaro kuti uwane ruzivo rwemhando dzerezinesi uye kuisirwa komputa ine rezinesi.
Installation uye Activation
Onawo zvikamu zveMigration Issues uye Limitations kuti uwane ruzivo rwakakosha nezveazvino rezinesi maneja anosanganisirwa neiyi compiler.
Kana uchishandisa MPLAB IDE, ita shuwa yekuisa yazvino MPLAB X IDE vhezheni 5.0 kana gare gare usati waisa chishandiso ichi. Rega IDE usati waisa compiler. Mhanyai .exe (Windows), .run (Linux) kana app (macOS) compiler installer application, eg XC8-1.00.11403-windows.exe uye tevera mazano ari pahwindo.
The default installation directory inokurudzirwa. Kana iwe uri kushandisa Linux, iwe unofanirwa kuisa iyo compiler uchishandisa terminal uye kubva kumudzi account. Isa uchishandisa macOS account ine maneja ropafadzo.
Activation ikozvino inoitwa zvakasiyana kuisa. Ona gwaro Rezenisi Maneja weMPLAB® XC C Compilers (DS52059) kuti uwane rumwe ruzivo.
Kana ukasarudza kumhanyisa compiler pasi perezinesi rekuongorora, iwe zvino uchawana yambiro panguva yekuunganidza kana iwe uri mukati memazuva gumi nemana ekupera kwenguva yako yekuongorora. Yambiro imwechete inopihwa kana iwe uri mukati memazuva gumi nemana kubva pakupera kwekunyorera kwako kweHPA.
Iyo XC Network License Server ndeye yakasarudzika yekuisa uye haina kuisirwa mune imwechete-mushandisi compiler simisi.
Iyo XC License Manager ikozvino inotsigira kutenderera kwemarezinesi etiweki anoyangarara. Yakanangana nevashandisi venhare, chimiro ichi chinobvumira rezinesi rinoyangarara kuti riende kure netiweki kwenguva pfupi. Uchishandisa chimiro ichi, unogona kubvisa kubva kunetiweki uye uchiri kushandisa yako MPLAB XC compiler. Ona iyo doc dhairekitori yeXCLM isa kune zvimwe pane ichi chimiro. MPLAB X IDE inosanganisira hwindo reMarezenisi (Zvishandiso> Marezenisi) kuti utarise kutenderera.
Kugadzirisa Matambudziko Ekuisa
Kana iwe uchinetseka nekuisa iyo compiler pasi peese maWindows anoshanda masisitimu, edza anotevera mazano.
- Mhanya iyo yekuisa semutungamiri.
- Seta zvibvumirano zveisina application ku 'Full control'. (Tinya-kurudyi pa file, sarudza Properties, Chengetedzo tebhu, sarudza mushandisi, gadzirisa.)
- Seta mvumo yeiyo temp folda ku "Kudzora Kwakazara!
Kuti uone nzvimbo yeiyo temp folda, nyora % temp% muRun command (Windows logo kiyi + R). Izvi zvichavhura a file Explorer dialog inoratidza iro dhairekitori uye ichakubvumidza iwe kuona nzira yeiyo folda.

Izvi hazvizokanganisa zvishandiso zvisina chirongwa chendangariro chakamisikidzwa munzvimbo yekurangarira data, uye hazvizokanganisa chero chinhu chinotangwa.
Kubuda kwakashata nenzira isiriyo yeDFP (XCS-2376) Kana iyo compiler ikakumbirwa neiyo isiriyo DFP nzira uye 'spec' file chiripo chemudziyo wakasarudzwa, muunganidzi haasi kutaura chisipo chemhuri paki uye pachinzvimbo chekusarudza iyo 'spec' file, izvo zvinogona kuzotungamira kune zvisiri izvo. Iyo 'spec' files inogona kunge isiri kuenderana nemaDFP akagoverwa uye akaitirwa kushandiswa neyemukati compiler kuyedzwa chete.
Memory overlap isina kuonekwa (XCS-1966) Iyo compiler haisi kuona kupindirana kwendangariro kwezvinhu zvakaitwa mhedziso pakero (kuburikidza ne ()) uye zvimwe zvinhu zvinoshandisa chikamu () chinofananidzira uye icho chakabatana nekero imwe chete.
Kukundikana nemabasa eraibhurari uye _meme (XCS-1763) Inonzi limbic float inoshanda nekupokana mu _memo kero nzvimbo inogona kutadza. Ziva kuti raibhurari routines dzinodanwa kubva kune vamwe C vanoshanda, saka, kune example, iyo inotevera kodhi inobatwa: dzoka regFloatVar > memxFloatVar;
Yakaganhurirwa limbic kuita (AVRTC-731) Kune iyo ATTiny4/5/9/10/20/40 zvigadzirwa, yakajairwa C / Math raibhurari yekushandiswa mune limbic ishoma kana kuti haipo.
Chirongwa chekuyeuka zvisingakwanisi (AVRTC-732) Purogiramu yekuyeuka mifananidzo inopfuura 128 kb inotsigirwa nechoolchain; zvisinei, kune zviitiko zvinozivikanwa zve linker kubvisa pamuviri pasina kuzorora uye pasina anobatsira kukanganisa meseji pane kugadzira inodiwa basa stubs kana -relax sarudzo inoshandiswa.
Zita nzvimbo inogumira (AVRTC-733) Nzvimbo dzekero dzine mazita dzinotsigirwa neturusi, zvichienderana nezvinogumira zvinotaurwa muchikamu chegwaro remushandisi Special Type Qualifiers.
Nzvimbo dzenguva The mabasa eraibhurari anofungidzira GMT uye haatsigire nzvimbo dzenguva dzemuno, saka nguva yemuno () ichadzoka panguva imwe chete segummite (), kune ex.ample.
