\"Uurime<\/p>\n

<\/p>\n

Parandame heligeneraatori n\u00e4idet<\/h2>\n

<\/p>\n

Eelmises osas artiklis<\/a><\/noindex> Me kirjutasime heligeneraatori rakenduse ja selle abil saime heli arvuti k\u00f5larist. N\u00fc\u00fcd keskendume sellele, et meie programm, l\u00f5petades t\u00f6\u00f6, ei tagasta m\u00e4lu kuhja. Aeg on selgusele j\u00f5uda.<\/p>\n

<\/a><\/noindex><\/p>\n

P\u00e4rast seda, kui skeem ei ole enam vajalik, peab m\u00e4lu vabastamine algama andmevoo peatamisest. Selleks tuleb skeemilt eemaldada kellaallikas, ticker, kasutades funktsiooni ms_ticker_detach()<\/em>. Me peame eemaldama tickeri filtri sisendist voidsource<\/em>:<\/p>\n

<\/p>\n

ms_ticker_detach(ticker, voidsource)<\/code><\/pre>\n
<\/p>\n
Muide, p\u00e4rast andmevoo peatamist saame skeemi muuta ja uuesti t\u00f6\u00f6le panna, \u00fchendades tickeri tagasi.<\/p>\n
<\/p>\n
N\u00fc\u00fcd saame selle eemaldada, kasutades funktsiooni ms_ticker_destroy()<\/em>:<\/p>\n
<\/p>\n
ms_ticker_destroy(ticker)<\/code><\/pre>\n
<\/p>\n
Andmevoog on peatatud ja saame alustada selle osade lammutamist, lahutades filtrid. Selleks kasutatakse funktsiooni ms_filter_unlink()<\/em>:<\/p>\n
<\/p>\n
ms_filter_unlink(voidsource, 0, dtmfgen, 0);\nms_filter_unlink(dtmfgen, 0, snd_card_write, 0);<\/code><\/pre>\n
<\/p>\n
argumentide t\u00e4hendus on sama, mis funktsioonil ms_filter_link()<\/em>.<\/p>\n
<\/p>\n
Eemaldame n\u00fc\u00fcd juba lahutatud filtrid funktsiooni abil ms_filter_destroy()<\/em>:<\/p>\n
<\/p>\n
ms_filter_destroy(voidsource);\nms_filter_destroy(dtmfgen);\nms_filter_destroy(snd_card_write);<\/code><\/pre>\n
<\/p>\n
Nende ridade lisamine meie n\u00e4itle seni, programmis m\u00e4lu haldamise seisukohast korrektse l\u00f5petamise.<\/p>\n
<\/p>\n
Nagu n\u00e4eme, n\u00f5udis programmist korrap\u00e4rane l\u00f5petamine meilt ligikaudu sama palju koodiridu, kui selle alguses, kusjuures iga filtri keskmine oli neli koodirida. See t\u00e4hendab, et programmi koodimaht suureneb proportsionaalselt kasutatud filtrite arvuga projektis. Kui r\u00e4\u00e4kida tuhandest filtrist skeemis, lisandub teie koodile neli tuhat rida rutiinseid operatsioone nende loomise ja h\u00e4vitamise protsessiks.<\/p>\n

<\/p>\n
Meedian\u00e4itlejate arendajad ei ole ette n\u00e4inud programmmilisi vahendeid filtrite manipuleerimise h\u00f5lbustamiseks skeemide kokkupanekul ja lahtiv\u00f5tmisel. Siiski on seal abiprogramm, mis v\u00f5imaldab filtreid kiiresti skeemist lisada\/eemaldada.<\/p>\n
<\/p>\n
Tagasi p\u00f6\u00f6rdume selle probleemi lahendamise juurde hiljem, kui filtrite arv meie n\u00e4idetes \u00fcletab paari tosina.<\/p>\n
<\/p>\n
J\u00e4rgmisel artiklis<\/a><\/noindex> koondame signaali taseme m\u00f5\u00f5turi skeemi ja \u00f5pime lugema m\u00f5\u00f5tmistulemust filtrist. Hindame m\u00f5\u00f5tmise t\u00e4psust.<\/p>\n
