Pic-pūmana. Papatono Pic-pūmana. Kaupapa o te Pic-pūmana

A, no te hanga kaupapa, e hiahia ana koe ki te whai te tangata te tahi mea ranei ki te aroturuki i te whakatinanatanga o ngā mahi e tika ana. Ko te tino raruraru hoki te tangata, kia rite ki te mea e tika ana ki te whakamahi i te maha nui o ngā huānga rerekē e tukua ki te whakahaere i to ratou mahi (transistors, parenga, thyristors, te p, pūnga iahiko, me ētahi atu). Ko taea katoa te ara iahiko matatini, me te nui kia whakahaeretia e te pūmana (MCU). E he ratou, mo te tauira, ka kia whakaahuatia hapu RІS. Na, he aha te mea te Pic-pūmana mō te horoi,? He aha te kaupapa o ratou me te wahi e whakamahia ratou.

He aha te mea microcontroller E varu

Pic-pūmana (microcontroller ranei) ko te tikanga he aunoatanga mahi etahi mahi mā te whakamahi i tētahi hōtaka rite i mua. He āhuatanga o te māngai o tenei aho o ngā hua ko te humarie o te hōtaka, me te wātea o te mahi e tika ana katoa ki te mahi. E whakaatu tona hanganga, kia tuhia te reira e i roto i tona hanganga e kotahi anake karaihe silicon (he āhuatanga huru o microcontrollers katoa). Haunga reira, Pic-pūmana kua he maha etahi o waewae. Ka taea te whakamahi ētahi o ratou rite ngā kōkuhunga arorau rite whakaputanga wahi, te toenga i tetahi tono më. Ko te waewae e taea e rānei mamati tairitenga ranei.

Hoki te nuinga o te pūmana mahi RІS nui me te ngaohiko pūmau - 5V. Ko te nui tenei kia taea te mahi i te reira i roto i tona aratau noa, me te mahi i te hōtaka tukua i roto i te mua o ia ia. Papatono Pic-pūmana tika i te rorohiko e kore e taea. Hoki tenei whakaaro i te kaihātepe.

whānau pūmana

e kore e Pic-pūmana te tīariari i roto i te kape kotahi. Ko te kaihanga hua te whānuitanga nui o microcontrollers, ia o nei he ona ake āhuatanga, kaha me ngā whāinga pea o tono. mau utuafare Tau ratou kaua nui, me te tei runga i te āhuatanga wehewehe tangohia nei rite taunoa. Na reira ko te reira e tika ana ki te whakamōhio anake e pā ana ki te whakarōpū taketake i roto i nei i reira e toru anake hapu o 8-, 16- me moka-32. E wehea ēnei i roto i te tahuri ki ētahi atu, engari no te mea o te whānau e kore e ratou te kaupapa o te tuhinga, te tahi mea e pā ana ki a ratou, a e kore e kawe ki runga ki te whakahaere.

te wahi e hāngai

Nā ki tona ringa rehe e Pic-pūmana taea te tono tata ki hea. Ka taea e Sami microcontrollers te kitea i roto i refrigerators, televisions, mīhini horoi. Ko RІS whānuitanga o ngā hua e te āhuatanga e he rongonui i roto i amateurs irirangi me karetao whakaako-whaiaro te iahiko i Pic-pūmana. Ki te to ratou awhina, ka taea e koe ngāwari whakarite i te pae ki te mahi, whakaaro katoa ranei. whai wāhi te reira ki te rongonui o te utu whaitake, noho noa o te hōtaka, me te nui nui o te rauemi mātauranga.

Te whakamahi Pic-pūmana ina hanga e koe waka i runga i te mana reo irirangi, ringa robotic me ētahi atu taonga e taea te mahi, iti pūtea. Ka taea te te whakamahi mō te tahi mea hua - tino rongonui ko te kaupapa o te hanga i te mihini aunoa whaiaro-hanga, te mana e te microcontroller. Ko te tūāwhiorangi o te whakamahi whanui, a ka taea e te huarahi tika kia whakamana tata tetahi whakaaro, kia taea te kite i te ara iahiko i roto i te Pic-pūmana kore anake i runga i nga fakatupu runaruna.

Pūmanawa mō te whakamahi ki te Pic-pūmana

Ko te pūmanawa iti tika - tuhipoka reira. Otiia e tika ana ki te tohatoha noa, ka taea e koe te whakamahi i, ka whakaekea e te taputapu MPLAB pūmanawa kaiwhakanao. More ïa, te pūmanawa rārangi (te taiao whanaketanga, compilers) MPLAB. Nā ki te kaupapa here kamupene, he utu ia, engari kua etahi fakangatangata. Ko te kupu, i roto i te putanga demo poto taea e koe te tamata i roto i te mau rave'a katoa, engari i muri i ka hatepea ona taumahinga otinga o te hōtaka. He taputapu nui e hanga e mea ohie ki te hanga i ngā hōtaka, watea ki te titiro mo te momo o ngā wāhi raruraru me te waehere whakahaere arotautanga te hōtaka tonu. Tei runga i te putanga o te mahi e taea te poroa waehere arotautanga, heke te maha o ngā pūmana e kua tautokona e te hōtaka ranei. Hoki te whakaaro o te pono kia mea ai e mau tautoko i te kamupene te māngai tino rongonui anake.

He he maha o te pūmanawa e whakaratohia ana e ētahi atu kamupene. I roto i te whānui, he rite ratou taumahinga, engari i reira he rerekētanga. Na, he tokomaha kua whakahuatia amuamu e he ta'emateaki ki te hoahoa faatumuhia-kaiwhakamahi MPLAB. Na reira, kei te petipeti i kaiwhakanao i runga i te tiaki i te mahi cutoff me te mämä o ratou pūmanawa. Hōtaka mō te Pic-pūmana he rawa kanorau, pera konei ko te nuinga he mea o reka.

Te hanga i tētahi hōtaka mo te Pic-kaiwhakahaere

Hei waihanga i tētahi hōtaka motuhake, ka taea e koe te whakamahi i te pūmanawa e tika ana, a tae noa te pukapuka ohie. Ko te whakawhetai taea ki te meka e mahi i te reira ki te reo hōtaka pērā i Assembler me C. Ko te rerekētanga matua takoto i roto i te maha o te mōhiohio tikanga me te humarie o te mahi raraunga tenei. Ka taea e koe te rongo i te rota e pā ana ki te whīwhiwhi o C, engari huihui uaua ake ka titau te huarahi tupato.

Hei tauira, ka hanga i tētahi hōtaka, me whakapūtā koutou hoki e pūmana te tikanga reira. kia waiho te reira e tika ana ki te kawe i roto i te maha o ngā kōwhiringa, engari me kawea e ratou ki waho i roto i te aroaro o te wheako mahi whakawhirinaki-whaiaro ranei, no te mea hape e taea arahi ki te meka e tahuri microcontrollers tikanga ki mongamonga o kirihou me te rino.

Papatono ki te hōtaka

Ko e founga ki te whakawhiti i te hōtaka whakawhanakehia i roto i te microcontroller iho? Nahea te hōtaka microcontroller? Hoki tenei whakaaro i reira he whakaaro motuhake - hötaka. tonoa ratou tohu ki te microcontroller e whakaputa ke pūtau i roto i te mahara i raro i te hōtaka. Hei timata i te tukanga o te whakawhiti te raraunga e hiahia ana koe ki te kōkuhu i te maramara i roto i te hōtaka, me reira, i roto i tahuri, hono ki te rorohiko. Na, te whakamahi i te pūmanawa kia rere koutou i te mārō. Tikanga papatono Pic-pūmana toro i toru hēkona ki rua meneti.

puka hötaka

E rorohiko ki te tīpako ki te tuhi i tētahi hōtaka i runga i te microcontroller? Taea te pakeke te te wehea ki ngā momo e toru: whaiaro hanga-, i te kaiwhakanao me te wheketere o te tahi atu kamupene. Ko te whakamahi o ia o ratou kua ona ake āhuatanga.

Ko te kupu, Ko tika cheap nga hötaka whaiaro-hanga. Ko to ratou whakamahi, he mahi wehe ki te meka e ngāwari taea tahuri ratou te pūrere ki te wahi o te kirihou me te rino. Na microcontroller hōtaka kia i roto i ngā take pērā tono te mau hopearaa kino i roto i te puka o te ru hiko, na kia piri koe ki te haumaru. I tua atu, ki te hanga e koe koe i te wahanga, he reira maha he hua ki te āhua iti e taea e pā ana ki te huringa mahi whare. Otiia i roto i te whatunga ao, ka taea e kitea e koe i te maha nui o rongoā ki tenei raruraru whakaarohia e te tahi atu iwi, me e kore pea e hoatu e koutou raruraru.

Ko te rorohiko taketake i te kaiwhakanao ka taea ki te qualitatively kawe atu ratou mahi ki tetahi microcontroller. I reira i reira ko te taurangi, me te mea i muri i te fariiraa i te kore e mahi i te reira, te whakakapi kahore raruraru. Otiia i roto i te kaupapa o mea, ina e kawea te mārō Pic-pūmana reira i roto i kahore raruraru.

Ko kakau i tona rironga o te utu tika tiketike.

Hötaka tukuna e ētahi atu kamupene, whai i te tika whānui o ngā e mahi ngā. Ratou āhuatanga ko te utu iti, me te / te whai wāhi ki te mahi tahi me ētahi atu microcontrollers i roto i te tua ki Pic ranei. He he ano hoki he pono ao "taniwha" e taea whakarato ngā momo rerekē o te mahi, engari no te mea o te hiahia mo te maha nui o pūhui o ratou utu iti e kore e tupu.

āhuatanga schematic

A te mutunga, he torutoru nga kupu e pā ana ki ngā tauira image. kia arotahi te reira i runga i nga waewae i runga i te pūtake o tautoko tuhinga, rite maha rerekē schematically microcontrollers i te whakatau Unuunu tūturu. Ko te mea matua i roto i ngā take pērā e hainatia whakatau, a ko taua mea mo ratou, a kia ngā mo te pūrere.
