Hana ʻia nā papa kaapuni paʻi MDB1986, (c) Na ka mea kākau ke kiʻi
Pono wau e kūʻai aku i nā ʻāpana "ma koʻu mau kuli" me kahi hao hao 40-watt a me POS-61 solder, no ka mea ʻaʻole liʻiliʻi wau e kūʻai aku, 1-2 mau manawa i ka makahiki, a ua maloʻo ka paʻi. Pono au e hoʻololi i ka mana CS32F103 Kina i ka STM32F103 kumu, a laila hoʻololi i ka hoʻomanaʻo. Ma keʻano laulā, ua hauʻoli loa wau i ka hopena, ʻoiai ʻaʻole wau i nānā i ka hana o RS-232 a me CAN.
MDB1986 debug papa i ka hana - ia e alohilohi a mehana, (c) Kiʻi na ka mea kākau
Ma ka pūnaewele Milandra hiki iā ʻoe ke loaʻa lawa moʻo 1986BE9 (Cortex-M3 core), akā no ka microcontroller K1986BE1QI (aviation) ʻaʻole wau ʻike i kekahi mea ma laila. Ma hope o ka nānā ʻana i nā mea hana, nā manual a me nā hana hoʻokolohua no nā kulanui i paʻi ʻia ma laila, hauʻoli wau i ka hoʻomaʻamaʻa ʻia ʻana o nā limahana ma ka ʻāina e hana pū me nā mea hoʻokele Lūkini. Hoʻomākaukau ka hapa nui o nā mea hoʻomaʻamaʻa no ka hana ʻana me nā awa I/O, timers, ADC, DAC, SPI, UART. Hoʻohana ʻia nā wahi hoʻomohala IDE like ʻole (Keil, IAR, CodeMaster). Ma kahi e hoʻohana ai lākou i nā papa inoa CMSIS, a ma kahi e hoʻohana ai lākou i ka MDR Library. Pono e haʻi ʻia nā kumuwaiwai , aia nā ʻatikala he nui mai ka hoʻomaʻamaʻa ʻana i nā mea polokalamu. A, ʻoiaʻiʻo, ʻaʻole pono mākou e poina .
Manaʻo e pili ana iā MilandraKe ulu nei ka Microelectronics ma Rūsia, a he kuleana koʻikoʻi ka hui ʻo Milander i kēia kaʻina hana. Ke ʻike ʻia nei nā microcontrollers hoihoi hou, no ka laʻana, 1986BE81T a me Elektrosila me SpaceWire a me MKIO interfaces (e like me 1986BE1 a me nā pilikia like ʻole), etc. Akā ʻaʻole hiki i nā haumāna maʻamau, nā kumu a me nā ʻenekini kīwila ke kūʻai i kēlā microcircuits. ʻO ke ʻano kēia ʻaʻole hiki i ke kaiāulu ʻenekinia ke ʻike koke i nā hewa a me nā pilikia me kēia chip. Me he mea lā iaʻu ka mea mua e pono ai e hana i nā microcircuits i loko o kahi pahu plastik, e hāʻawi iā lākou i nā poʻe makemake āpau, a ma hope o ka ʻae ʻia (Latin approbatio - ʻae ʻia, ʻike ʻia) e nā loea, hiki iā lākou ke hoʻomākaukau i ka hoʻoponopono hou ʻana i kahi pahu metala-ceramic. palekana mai nā mea weliweli a pau. Manaʻo wau i ka wā e hiki mai ana e ʻoliʻoli mākou i nā papahana hou i hoʻolaha ʻia ma nā hōʻike.
Hiki ke hana hou, hoʻololi a hoʻohana ʻia ka papa debug aʻu i kūkulu ai e kekahi i ke kaʻina hoʻonaʻauao. ʻO ka mea mua, ua hana wau i ka papa noʻu iho, akā maikaʻi loa ia .
ʻO K1986BE1QI (air) he mea hoʻoponopono hoihoi loa me nā loulou kū hoʻokahi i hiki ke hoʻohana ʻia i nā kulanui e aʻo i nā haumāna. Manaʻo wau ma hope o ka hoʻoponopono ʻana i nā hewa i ʻike ʻia i loko o ka mea hoʻoponopono a me ka hele ʻana i nā hoʻokolohua hōʻoia, e lele ka mea hoʻoponopono i ke ʻano maoli o ka ʻōlelo!
