ʻAʻohe kānalua e pili ana i ka pono o nā papa berena solderless hilinaʻi, akā pono ʻoe e ʻae ʻaʻole lākou i hemolele. ʻOiaʻiʻo, ʻaʻole lākou i kūpono no kekahi mau ʻano kaapuni, akā ʻoi aku ka liʻiliʻi o ka pilikia ma mua o nā mea me nā jumpers. E pau ka poʻe mālama ʻole i ka hihia me ka manaʻolana ʻole i loko o kahi puʻu o nā jumpers me kā lākou mau ʻāpana, a e hoʻolilo ka poʻe picky i ka manawa hou aku e hoʻomaʻemaʻe i nā jumpers ma mua o ka hana ʻana i kahi prototype o ke kaapuni ponoʻī. He aha kaʻu e hana ai?
ʻO kahi ala e hoʻoponopono ai i kēia pilikia, ʻo ia ka hana ʻana i kahi papa berena solderless me ka ʻole o nā jumpers. ʻO kēia ka manaʻo ma hope o nā "huahana bakery" a [Kevin Santo Cappuccio]. ʻO ka manaʻo, ʻo ia ka hoʻoponopono ʻana i ka papa berena maʻamau i hiki ke hoʻokumu ʻia ka pilina ma waena o kekahi mau ʻāpana pili maʻamau a me ke alahao mana i loko o ka polokalamu. ʻO ka hana ma hope o kēia, ʻo ia ke hoʻohālike i ka matrix chip switch CMOS, ʻoiai ka MT8816AP. Hiki i nā kuapo crosspoint 128 i kēlā me kēia chip ke lawelawe i nā voltages a hiki i ± 12 volts, no laila he nui nā kaapuni e hiki ke hoʻohana i kēia mau jumpers silicon programmable.
[Kevin] ʻO ka mana o kēia manawa he 0.2, kūpono kona nui ma lalo o kahi papa berena solderless, a he liʻiliʻi ka pūʻolo. Ua kaʻana like ʻo ia i nā kikoʻī e pili ana i ka hoʻopili ʻana i nā pilina papa berena, kahi mea i like me he hana ʻeha: e huki i nā pilina, ʻoki i kahi lepili liʻiliʻi ma ka hopena o ka ʻauwai, a laila e kulou i lalo e hana i ka paʻi alakaʻi o ka papa kaapuni ma o ka lua. Me he mea lā he nui ka hana, pono e loaʻa kahi ala ʻoi aku ka maikaʻi; Ua wehe maopopo ʻo [Kevin] i nā manaʻo.
ʻOiai ua ʻike mākou i ka hoʻololi ʻana o ke kiko keʻa i hoʻohana ʻia e hoʻomaikaʻi i nā papa berena solderless ma mua, ua ʻike mākou he mea ʻoluʻolu ka maʻalahi o kēia papahana. ʻO ka manaʻo o ka hoʻolei ʻana i kēia mau pana lele āpau he mea hoʻowalewale maoli nō ia.
He papahana maikaʻi loa kēia. ʻO kahi hoʻohui akamai, aia nā pale liʻiliʻi ma kēlā me kēia ʻaoʻao e hōʻike ana i ka pilina o kēia manawa.
Ke ʻole hiki iā ʻoe ke hoʻokō i kahi hōʻike LED 7-ʻāpana a i ʻole ka motika haʻalulu a i ʻole ka accelerometer a i ʻole ke kuapo DIP a i ʻole kekahi mau mea "leʻaleʻa a hoihoi".
Ua lawa ka 15mA (ImaxIO) e lawelawe i kekahi hōʻailona liʻiliʻi, ke makemake ʻoe i ke au hou aku, hiki iā ʻoe ke hoʻohana i kekahi bipolar a i ʻole FET, ma hope o nā mea a pau, he papa berena nō ia.
I koʻu wā e hana ana i nā prototypes, ua hana au i kahi PCB hoʻopaʻa ʻili hoʻokahi ʻaoʻao i loaʻa nā ʻāpana kikohoʻe a pau aʻu e pono ai a ua pīpī ʻia nā ʻāpana CPLD i lawe i nā hōʻailona "āpau" ma waena o nā ʻāpana. A laila e hoʻolālā wale i ka pilina ma VHDL. No laila, inā hana hewa wau a pono paha e hoʻololi i ka pilina, he hoʻololi code wale nō ia.
No kekahi o kēlā mau synthesizers analog kahi āu e hoʻokomo ai i nā kaula āpau, he mea maikaʻi loa kēia manaʻo.
ʻĀ, ke hālāwai wau me kahi papa berena aʻu e hilinaʻi nei, e pau wau i ka kānalua. No nā papa berena, pono mau ia e kuhi inā he hemahema ia i kāu hoʻolālā a i ʻole he hemahema i ka papa berena.
I mea e hoʻonui ai i ka pilikia, pono ʻoe e hoʻolālā kūikawā no nā hiki o ka papa berena, a ʻo nā mea e pono ai ke hoʻohālike ʻia, e like me ke hoʻololi ʻana i nā regs, ʻaʻole hana maikaʻi.
ʻAʻole makemake ka Analog a me ka wikiwiki kiʻekiʻe i nā parasitics, ʻaʻole koi ka digital a me ka wikiwiki haʻahaʻa i kahi kahua prototype i hana lima ʻia, inā ʻoe e makaʻala.
ʻAʻole au i ʻike i kekahi mea e pili ana i kēia mau mea āpau, akā ua manaʻolana mau wau no ia ʻano hoʻololi, a i kēlā me kēia manawa aʻu e nānā ai, ʻike wau ʻaʻole ia he ʻoiaʻiʻo. ʻOiai no nā kaapuni maʻalahi, pono ʻoe e hoʻohālikelike pono i ke kuapo i kāu mau koi maoli. A laila pono ʻoe e ʻae i kahi ʻano o ka hana makemake ʻole. He ʻoiaʻiʻo mau lākou i nā amps op gain unity a i ʻole kekahi ʻano transistors me ka bias voltage a i ʻole ke kūʻē.
ʻAʻole au i ʻike nui e pili ana i ka ʻenehana kumu. ʻAʻohe kiʻikuhi schematic o ka pilina maoli o ka pepa ʻikepili MT8816 aʻu i loaʻa ai. Akā i ka manawa koke (me ka manaʻo ua wehewehe pololei wau), ʻike wau ʻo ke au kiʻekiʻe loa he 15mA a ʻo ke kū'ē maʻamau he 45ohm ma Vdd=12. He ʻāpana hoihoi ia e hiki ke hoʻohana ʻia no nā mea he nui, akā nui ka ʻōlelo aʻo. Mana loa. ʻAʻole hiki iaʻu ke noʻonoʻo i kahi kaapuni hoʻokahi aʻu i hana ai me kahi papa berena e hiki ke hoʻololi ʻia. ʻOi loa aku no ka mea ua hoʻohana au i ka papa berena ma ke ʻano he ʻanuʻu ma mua o ke kāwili ʻana i ka papa berena... Ke hoʻohālikelike ʻia me kēia kuapo, ʻo ke ʻano ʻokoʻa loa o nā kaula i hiki ʻole ke hoʻomaka.
Inā maopopo iaʻu pehea e hana maikaʻi ai ke kaapuni e wānana i ka hopena o kēia pilina ma luna o ia, a laila ʻaʻole pono wau i kahi papa berena ma kahi mua.
No nā hōʻailona liʻiliʻi e mālama ana i ke au haʻahaʻa, pono kēia e like me kahi kuapo kūpono. ʻOiaʻiʻo, e loli ke kū'ē ma muli o kou kūlana pololei i loko o ka pae voltage, akā pono ʻoe e hana me nā kiloohms, a ʻaʻole pono ia he mea nui inā ʻoe e hoʻohui i +-75 ohm i kēia hewa i kāu hoʻolālā. A i ʻole, ke hoʻolālā nei ʻoe i kahi kaapuni hiki ʻole ke kūkulu maoli ʻia ma muli o nā ʻae ʻana o nā ʻāpana.
ʻAe, ke loaʻa iā ʻoe kēia mea hana, hiki iā ʻoe ke hele i waho a hana i kahi papahana, ʻo kēia papahana he +/-75ohm hōʻailona liʻiliʻi pili ʻole. Akā, ʻaʻole au i hana i ia ʻano papahana. ʻAʻole hiki iaʻu ke noʻonoʻo i kahi papahana o kēia nui. ʻO nā helu maʻemaʻe wale nō ka mea e kūpono i nā kūlana, no kēia mea he nui kāu mau pilina a he kulu wale nō ka papa berena i loko o ka bākeke, a he kakaikahi nā pilina a makemake ʻoe e hoʻohana wale i kahi clip ic e lele i ke kaula.
ʻO kaʻoiaʻiʻo, hiki i ka hapalua o ke code i hoʻopau ʻia ma laila ke kau i kekahi alapine (a i ʻole kekahi hōʻailona) ma ka probe i hiki iā ʻoe ke hoʻokomo iā ia i nā lālani like ʻole a haʻi i ka papa i nā pilina āu e makemake ai e hana me ka ʻole o kahi kamepiula.
ʻO ka hana aʻe ma hope o koʻu loaʻa ʻana o nā mea kumu e hana maikaʻi ai, ʻo ia ka hana ʻana i kekahi o nā mea āu i ʻōlelo ai. Nui nā ala e hoʻoponopono ai i kēia pilikia. Manaʻo wau ʻo ke ala akamai loa, ʻo ia ke kau ʻana i kahi hōʻike ma luna o ka papa berena, akā ʻo ka hana ʻana i kahi hōʻike me ia ʻano porous e pono ai ka pae hoʻomohala o Samsung. ʻO kekahi ala ʻē aʻe, ʻo ia ke kau ʻana i kahi mea hoʻolele kiʻi liʻiliʻi a me kahi kāmela ma luna, akā ʻo nā mea a pau aʻu i hoʻohana ai e hoʻāʻo nei e hana i ia mau mea ua lohi loa a pilikia hoʻi e hoʻohana, a aia wale nō kahi ʻōpala e puhi ana a puni.
ʻAʻole ia he mea hiki ʻole ke hana i kekahi o kēia mau mea, pono wau e noʻonoʻo i kahi ala e hana ai i kēia me ka ʻole o ka mōhai ʻana i ka ʻike.
Makemake au i ka manaʻo o nā probes. Ma ke ʻano he hōʻailona, he rgb kēlā me kēia kolamu, a he code kala ponoʻī ko kēlā me kēia "ʻupena". ʻAʻole ia he akamai e like me nā mea hoʻolele kiʻi ma luna, akā ʻoi aku ka maʻalahi o ka hoʻokele ʻana i nā kaha ws281*.
ʻOiai i koʻu ʻike, he ʻōpala kēlā mau papa palaki aniani ʻaʻole i hoʻohana ʻia me ka hōʻailona, akā kani maʻalahi ke hoʻohui i ka hihia aniani me ka clip bb830 ma mua o kahi hōʻike me kahi lua. E wehe i nā koho hoʻonoho LED hou aʻe. Akā ʻo ke kau ʻana i nā LED ma luna a ma lalo o ka papa kaapuni ʻaʻole ia he manaʻo weliweli (koe wale nō ka mea e keakea iki ana ke alahao mana).
Makemake au i kēia manaʻo, a pono e aʻo pono i ka chip. Ua ʻimi au i kahi mea like-akā ma nā helu wale nō. Pono kēlā me kēia pine e loaʻa-ke kū'ē hiki ke hoʻolālā ʻia me-ke kū'ē hiki ke hoʻolālā ʻia i ka honua-set e like me ka hoʻokomo-set e like me ka hoʻopuka-set i ka tri-state āpau ma ke ʻano he poloka hoʻopaʻa inoa hoʻololi no kēlā me kēia pine, no laila hiki ke hoʻolālā ʻia ka polokalamu. Akā a hiki i kēia manawa ʻaʻohe FPGA/CPLD kūpono i loaʻa. No ka papa berena, pono e uhi ka ʻōnaehana ma ka liʻiliʻi he 60 mau pine 30+30. No ka mea ua hoʻokumu ʻia nā mea āpau ma nā hoʻopaʻa inoa hoʻololi, hiki ke hoʻonui maʻalahi ʻia. A hoʻomalu ʻia nā mea āpau e ka polokalamu.
Ma ka hoʻohana ʻana i kā mākou pūnaewele a me nā lawelawe, ʻae maopopo ʻoe i ke kau ʻana o kā mākou hana, hana a me nā kuki hoʻolaha. aʻo hou aku
