Kāore he ruarua mō te whai huatanga o ngā papa parāoa kore-whakapiri pono, engari me whakaae koe kāore i te tino tika. Ae, ehara i te mea pai mō ētahi momo ara iahiko, engari he iti ake te raruraru i ērā he pekepeke. Ka mutu, ka mau te hunga mangere ki roto i te puranga pekepeke me ō rātou wāhanga, ā, ka roa ake te wā e pau ana i te hunga whiriwhiri ki te whakarite i ngā pekepeke, kaua ki te hanga i tētahi tauira o te ara iahiko tonu. Me aha ahau?
Ko tētahi huarahi hei whakaoti i tēnei raruraru ko te hanga i tētahi papa taro kore-whakapiripiri, kāore he pekepeke. Koinei te whakaaro kei muri i ngā "hua tunu" a [Kevin Santo Cappuccio]. Ko te whakaaro he whakarite i te papa taro paerewa kia taea ai te whakatū i te hononga i waenga i tētahi takirua o ngā rīpene whakapā noa me te reriwe hiko i roto i te pūmanawa. Ko te mahi kei muri i tēnei ko te whakatauira i te matihiko maramara pana CMOS, inā koa te MT8816AP. 128 ngā pana whakawhiti ira mō ia maramara ka taea te whakahaere i ngā ngaohiko tae atu ki te ±12 volts, nō reira he maha ngā ara iahiko ka taea te whakamahi i ēnei pekepeke silicon ka taea te whakarite.
[Kevin] Ko te putanga o nāianei ko te 0.2, ka uru tōna rahi ki raro i tētahi papa parāoa kore-whakapiri, ā, he iti te kete. I tohaina e ia ngā taipitopito mō te hono i ngā hononga papa parāoa, he mahi uaua te āhua: tangohia ngā hononga, tapahia he tapanga iti ki te pito o te awaawa, kātahi ka piko ki raro hei hanga i te tānga mata o te papa porowhita. He āhua nui te mahi, me whai huarahi pai ake; e tuwhera ana a [Kevin] ki ngā whakaaro.
Ahakoa kua kite kē mātou i te whakawhiti-ira e whakamahia ana hei whakapai ake i ngā papa parāoa kore-whakapiri i mua, i kitea e mātou he mea ahuareka te māmā o tēnei kaupapa. He tino whakamatautauria te whakaaro ki te maka atu i ēnei whakaahua peke katoa.
He kaupapa tino pai tēnei. He tāpiri mohio ko ngā mata iti kei ia taha e whakaatu ana i te hononga o nāianei.
Ki te kore e taea e koe te whakamahi i tētahi whakaaturanga LED 7-wāhanga, i tētahi motuka wiri rānei, i tētahi ine whakatere, i tētahi pana DIP rānei, i tētahi atu wāhanga "ngahau, whakamere hoki".
He nui te 15mA (ImaxIO) hei whakahaere i tētahi tohu iti, ki te hiahia koe ki tētahi iahiko nui ake, ka taea e koe te whakamahi i ētahi tohu bipolar, FET rānei, he papa taro tonu.
I a au e hanga tauira ana, i hanga e au he PCB whakairi mata kotahi-taha kei roto ngā maramara matihiko katoa i hiahiatia e au, ā, i ruia ngā maramara CPLD e kawe ana i ngā tohu "katoa" i waenga i ngā maramara. Kātahi ka hōtaka noa i te hononga ki te VHDL. Nō reira, ki te hē ahau, ki te hiahia rānei ahau ki te whakarerekē i te hononga, he whakarerekētanga waehere noa iho.
Mō tētahi o ngā mīhini hanga taura anaro e mono ana i ngā taura katoa, he tino rawe tēnei whakaaro.
Āe, ina tūtaki ahau ki tētahi papa taro e whakawhirinakihia ana e au, ka mutu taku ruarua. Mō ngā papa taro, me *whakaaro tonu* mēnā he hapa kei roto i tō hoahoa, he hapa rānei kei roto i te papa taro.
Hei whakararuraru ake i te āhuatanga, me hoahoa motuhake koe mō ngā āheinga papa parāoa, ā, ko ngā mea e tika ana kia tauiratia, pērā i te whakawhiti ture, kāore e pai te mahi.
Kāore ngā mea anaro me ngā mea tere-teitei e pai ki ngā mea pirinoa, kāore ngā mea matihiko me ngā mea tere-iti e hiahia ki tētahi atamira tauira i hangaia e te ringa, ki te tupato koe.
Kāore au i te mōhio ki ēnei mea katoa, engari i tumanako tonu ahau mō tētahi huringa pēnei, ā, i ia wā ka titiro atu ahau, ka kitea e au kāore i te pono. Ahakoa mō ngā ara iahiko māmā, me āta whakataurite te pana ki ō hiahia tūturu. Kātahi ka hiahia tonu koe ki te whakaae ki tētahi taumata o ngā whanonga kāore e hiahiatia. He pono tonu ēnei, arā, ngā op amp kotahi-whakanui, ētahi momo transistor rānei me te pānga ngaohiko, te ātete rānei.
Kāore au i te tino mōhio ki te hangarau matua. Kāore he hoahoa kauwhata o te hononga tuturu i roto i te pepa raraunga MT8816 i kitea e au. Engari i kite tonu ahau (mehemea i tika taku whakamārama), ko te iahiko mōrahi he 15mA, ā, ko te ātete-ā-ringa noa he 45ohm i te Vdd=12. He wāhanga whakamere tēnei ka taea te whakamahi mō ngā mea maha, engari he nui te whakatūpato. He mana nui rawa atu. Kāore au e whakaaro ki tētahi ara iahiko kotahi kua hangaia e au me te papa taro ka taea te whakarerekē. Ina koa nā te mea i whakamahia e au te papa taro hei taahiraa i mua i te honohono i te papa taro... Ki te whakatauritea ki tēnei pana, nā te rerekētanga o ngā whanonga o ngā waea i kore ai e taea te tīmata.
Ki te mārama ahau ki te mahi a te ara iahiko kia taea ai e au te matapae i te pānga o tēnei hononga ki a ia, kāti kāore au e hiahia ki tētahi papa taro.
Mō ngā tohu iti e pupuri ana i te iahiko iti, me rite tēnei ki tētahi pana pai rawa atu. Ko te tikanga, ka rerekē te ātete-whakakā i runga i tō tūranga tika i roto i te awhe ngaohiko, engari me aro tonu koe ki ngā kiloohm, ā, kāore he aha mena ka tāpirihia e koe he +-75 ohm ki tēnei hapa i roto i tō hoahoa. Ki te kore, kei te hoahoa koe i tētahi ara iahiko kāore e taea te hanga nā ngā ātete wāhanga.
Āe, ina whiwhi koe i tēnei taputapu, ka taea e koe te haere ki waho ki te tito i tētahi kaupapa, he tohu iti noa iho tēnei kaupapa +/-75ohm kāore e pā ana. Engari kāore anō kia mahia e au tētahi kaupapa pēnei. Kāore au e whakaaro ki tētahi kaupapa pēnei te rahi. Ko ngā tau parakore anake te mea e tutuki ana i ngā paearu, mō tēnei he maha rawa ō hononga, he iti noa iho rānei te papa taro, he iti noa iho rānei ngā hononga, he pai ake ki a koe te whakamahi i tētahi topenga IC hei hono i te taura.
Ina hoki, ka taea e te haurua o te waehere kua oti te whakatakoto i tētahi auau (i tētahi atu tohu rānei) ki runga i te pūwhakamātautau kia taea ai e koe te mono ki ngā rarangi rerekē me te kī atu ki te papa ko ēhea hononga e hiahia ana koe ki te hanga me te kore he rorohiko.
Ko te mahi e whai ake nei i muri i taku whakahaere i ngā mea taketake kia pai te mahi ko te mahi i ētahi o ngā mea i kōrerotia e koe. He maha ngā huarahi hei whakaoti i tēnei raruraru. Ki taku whakaaro ko te huarahi tino mohio ko te tāuta i tētahi whakaaturanga ki runga i te papa taro, engari ko te hanga i tētahi whakaaturanga me tētahi whakaaturanga pore penei me whai taumata whanaketanga a Samsung. Ko tētahi atu huarahi ko te tāuta i tētahi pūwhakaata iti me tētahi kāmera ki runga, engari ko ngā mea katoa kua whakamahia e au e ngana ana ki te mahi i aua mea he puhoi rawa, he raruraru hoki ki te whakamahi, ā, he ipu para noa iho te mura.
Ehara i te mea kāore e taea te mahi i tētahi o ēnei mea, me kimi noa e au he huarahi hei mahi i tēnei me te kore e whakararu i te wheako.
He pai ki ahau te whakaaro o ngā pūwhakaata. Hei tohu, he rgb kei ia pou, ā, he waehere tae anō kei ia "kupenga". Ehara i te mea he atamai pērā i ngā pūwhakaata o runga, engari he māmā ake te whakahaere i ngā rīpene ws281*.
Ahakoa i roto i aku wheako, he para noa iho aua pereti kirihou mārama kāore i te waitohutia, engari he māmā ake te whakakotahi i te pouaka mārama me te topenga bb830 i te whakaaturanga he kōhao. Whakatuwheratia ētahi atu kōwhiringa whakanoho LED. Engari ehara i te mea kino te whakanoho i ngā LED ki runga ake, ki raro iho hoki i te papa hiko (engari he mea whakararu te ara hiko).
He pai ki ahau tēnei whakaaro, ā, me āta ako i te maramara. Kua rapu au i tētahi mea rite - engari he tau anake. Me whai ātete ka taea te whakarite i ia pine me te ātete ka taea te whakarite ki te whenua hei huinga tāuru hei huinga putanga hei huinga āhua-toru katoa hei poraka rēhita nekehanga mō ia pine, kia taea ai te whakarite pūmanawa. Engari tae noa ki tēnei wā, kāore anō kia kitea he FPGA/CPLD e tika ana. Mō te papa taro, me kapi te pūnaha i te iti rawa 60 ngā pine 30+30. Nā te mea kei runga katoa i ngā rēhita nekehanga, ka taea te whakawhānui ngāwari. Ā, ka whakahaerehia katoatia e te pūmanawa.
