He mea nui te PSRAM o waho mō ngā whakaaturanga he taumira neke atu i te 480×320, mō ngā atanga rānei e whakamahi ana i te hohonutanga tae 24-moka. Ka tautokohia e te kōwae te PSRAM tae atu ki te 32MB, e whakarato ana i te wāhi ārai anga me te rokiroki rawa whakairoiro. Ka taea e ngā tono taketake e whakamahi ana i ngā whakaaturanga iti ake me ngā papatae tae iti te whakahaere mā te whakamahi i te mahara ā-roto anake, ahakoa e taunakihia ana te PSRAM o waho mō te ngāwari o te whanaketanga.

He pēhea te whakataurite i te whakapaunga hiko ki ngā otinga kē atu?

E 200-300 mW te kaha e pau ana i te ESP32P4 i te wā e whakahaerehia ana te whakaaturanga me te Wi-Fi kua whakahohea, ki te whakaritea ki te 1.5-3 W e whakamahia ana mō ngā HMI ARM Cortex-A e whakahaere ana i te Linux. Ka roa ake te wā e whakahaerehia ana e ngā tono pākahiko, ā, ka whakaitihia e ngā tāutanga tonu-kāore ngā whakaritenga whakahaere wera me ngā utu whakahaere. Ka pau i ngā aratau moe hohonu te 10μA, ka taea ai te whakahaere tūtatari iti-mana.

Hurihia tō whanaketanga HMI me ngā otinga ESP32P4 a Guition

Kaua te whakawhanake i ngā atanga tangata-mīhini matatau e kī he whakaiti i te wā, te tahua, te ngāwari hangarau rānei. Ka tukuna e te kōwae JC-ESP32P4-M3-DEV a Guition ngā āheinga whakairoiro ngaio mā te tūāpapa i hangaia kia tere ake ai te huringa whanaketanga hua. Ko tō mātou tohungatanga hei kaiārahi Kōwae whakaaturanga ESP32P4 Ka whakarite te kaihanga kia whiwhi koe i ngā wāhanga anake engari i ngā otinga katoa e tautokona ana e te pūmanawa whakawhanake atanga Guition whānui, e whakaiti ana i tō kawenga mahi hangarau tae atu ki te 50%. Ahakoa kei te hanga tauira koe i ngā taputapu hauora auaha, kei te whakamahi i ngā pūnaha whakahaere ahumahi, kei te whakarewa rānei i ngā hua kāinga atamai, ka whakaratohia e tā mātou tīma hangarau te tautoko urupare puta noa i tō haerenga whakawhanake. Whakapā mai david@guition.com hei matapaki i ō whakaritenga atanga motuhake, hei tono mō ngā kōwae aromatawai, hei tūhura rānei i te utu rahinga mō te whakatinanatanga whakaputa.
