Mana whakahaere motuka

Tukutahitanga me te Wā
Ko ngā kaupapa matua o ia tono wā-tūturu ko te wā tika, te tukutahitanga me te urupare pūnaha kua whakaritea, ā, me aro nui ki ēnei āhuatanga i te wā e hoahoa ana.te mana whakahaere motukapūmanawa. Ko te tikanga, he tino māmā te ahua o te tukanga: ka pānuihia e te pūnaha ngā uara pūoko, ka tukatukahia te raupaparorohiko whakahaere, ka aroturukihia te haumaru o te pūnaha, ā, ka whakahaere i te wāhanga putanga mā te whakarerekē i te huringa mahi o te putanga PWM.
Ka taea e ngā hapa iti o te wā te arahi ki ngā hapa urupare nui o te pūnaha, te mahi pōturi me te mahi ngoikore. Kia pai ai te mahi o ngā mea katoa, he mea nui kia noho rite tonu, kia mau tonu hoki te whakatau tika o te pūnaha. I konei, e hiahia ana ahau ki te whakanui kei te pāngia tātou e tētahi 'pūnaha wā-tūturu uaua', ā, he mea tino nui te whakatutuki i ngā wā kati poto.
Ka taea te whakatinana i te pūmanawa whakahaere motuka hei otinga whakarewa-kore, kāore he pūnaha whakahaere, mā te whakamahi i te RTOS (pūnaha whakahaere wā-tūturu) e tika ana, hei otinga ranu maha-matua rānei, e rere ana ētahi matua CPU i te aratau whakarewa-kore, ko ētahi e whakamahi ana i te pūnaha whakahaere. Ko ngā otinga whakarewa-kore e hangai tonu ana ki tētahi hoahoa e peia ana e te aukati, e whakahaere ana ngā aukati i ngā mahi wā-nui, ā, e whakarite ana kia puta ngā mea katoa i ngā wā tika.
Ahakoa he otinga bare-metal, RTOS, he otinga ranu rānei, me whakahaere te tātari wā, te whakatau kaupapa mahi me te tātari haumarutanga kia pai ai, kia pono ai hoki te mahi a te pūnaha.
Mā te tātari wā ka oti ngā mahi katoa i te wā tika. Kei roto i tēnei ko te whakaaro ki te wā mahi kino rawa atu mō ia mahi. Ko ētahi o ngā mahi matua o te whakahaere motuka ko te kohikohi raraunga pūoko, te whakahaere i ngā rauropi whakahaere mā te whakaputa tohu PWM, te kimi me te whakahaere hapa, ngā mahi aukati ohorere me te haumaru, te whakawhitiwhiti kōrero wā-tūturu me ētahi atu wāhanga pūnaha, me te tukutahi me ngā pūnaha o waho.

Pūnaha whakahaere wā-tūturu (RTOS)
He mea nui te whiriwhiri i te RTOS tika mō tō tono whakahaere motuka kia pai ai te mahi, te pono me te haumaru. Ko ngā whakaaro matua ko te mahi wā-tūturu a te RTOS, te whai huatanga o ngā rauemi tae atu ki te tapuwae mahara me te whakamahinga CPU, me te tukatuka whakaritenga mua e ahu mai ana i te kaupapa matua. Ko ngā aukati tere me te whai hua, me te pono me te pakari o te pūnaha, he mea nui anō hoki. Ko te tautoko me te tuhinga a te kaihoko, te hototahi ki ngā taputapu, me te wātea o ngā taputapu whanaketanga (pēnei i ngā IDE, ngā patuiro, me ngā tātari) me ngā pūnaha rauropi (tae atu ki ngā whare pukapuka me ngā tauira waehere) he mahi nui. Hei whakamutunga, me whakaaro anō hoki ki ngā tikanga raihana me te utu o te RTOS.
I runga i ngā āhuatanga me ngā whakaritenga motuhake o ngā tono whakahaere motuka, he kōwhiringa pai rawa atu a FreeRTOS, he pūnaha whakahaere tuwhera-wā-tūturu rongonui e mōhiotia ana mō tōna pai me te maha o ngā whakamahinga. He tino whai hua tēnei kōwhiringa i roto i ngā horopaki e whakaarohia ana ko te whai huatanga o te utu, te whai huatanga o te whakahaere, te ngāwari o te pūnaha, te pono me te pakari, te ngāwari o te whakamahi, te tautoko taputapu whānui me te whai huatanga o ngā rauemi he mea nui.
