Kākoʻo Python no FTDI Products Software User Guide

ʻO ka hoʻohana ʻana i nā hāmeʻa FTDI i ke kākoʻo ola a / a i ʻole nā noi palekana e pili ana i ka pilikia o ka mea hoʻohana, a ua ʻae ka mea hoʻohana e pale, hoʻopaʻa, a paʻa ʻole i ka FTDI mai nā pōʻino a pau, nā koi, nā hoʻopiʻi, a me nā lilo i hopena mai ia hoʻohana.

Hoʻolauna

Hoʻohana maʻamau ʻia ʻo Python no ka hoʻomohala ʻana i nā polokalamu, ka automation hana, ka ʻikepili ʻikepili, a me nā mea ʻē aʻe.
Hōʻike kēia ʻatikala ʻenehana i nā ala e hiki ai ke hoʻohana ʻia ka polokalamu Python e nā huahana FTDI e hilinaʻi nei i ka maʻamau o FTDI Keaukaha VCP or Keaukaha D2xx.
Nui nō hoʻi nā hale waihona puke python ʻaoʻao ʻekolu e hōʻike ʻia ana a ua helu ʻia kēia ma aneʻi.
Loaʻa ke kākoʻo Python no FT600/1 ICs e hoʻohana ana i ka mea hoʻokele D3xx akā ʻaʻole i uhi ʻia i kēia palapala. E ʻoluʻolu e ʻike i nā ʻaoʻao huahana no kēia mau IC no ka ʻike hou aku.

He aha ka polokalamu Python?

Ke lilo nei ʻo Python i ʻōlelo papahana kaulana loa.
Hiki ke hoʻohana ʻia no ka prototyping wikiwiki, a i ʻole no ka hoʻomohala ʻana i ka lako polokalamu mākaukau.
Hana ʻia ia ma nā paepae like ʻole (e laʻa, Windows, MacOS, Linux, etc.) a he syntax maʻalahi e like me ka ʻōlelo Pelekania. Hāʻawi kēia syntax i nā mea hoʻomohala e kākau i nā papahana me nā laina liʻiliʻi ma mua o kekahi mau ʻōlelo papahana ʻē aʻe.
Holo ʻo Python ma kahi ʻōnaehana unuhi, ʻo ia hoʻi, hiki ke hoʻokō ʻia ke code i ka wā i kākau ʻia ai ʻo ia ka wikiwiki o ka prototyping.
Nui nā kumuwaiwai pūnaewele i loaʻa no Python me kēia ka mea nui webkahua: https://www.python.org/

Kākoʻo Keaukaha Python

Hōʻike kēia ʻāpana i ka hoʻohana ʻana i ka mea hoʻokele VCP a me D2xx o FTDI me ka polokalamu Python.

VCP

He ex maʻalahi kēia ʻāpanaampe wehe i kahi awa COM me ka hoʻohana ʻana i ka mea hoʻokele VCP, e hōʻike i ke awa COM i wehe ʻia i ka pale a laila e hoʻouna a loaʻa i kekahi mau huaʻōlelo i ke awa hāmama a hōʻike i nā mea ma ka pale. Hōʻike ʻia ka hopena mai ke code ma lalo nei. E hoʻomaopopo ua hoʻohana ʻia kahi kaula FTDI me TX i RX loopback no ka hoʻāʻo maʻalahi.

Loaʻa ka papa inoa code ma Pākuʻi C – Serialtest.py.
No ka holo ʻana i kēia code, pono ʻoe e hoʻokomo i ka waihona pyserial. Hiki iā ʻoe ke hana i kēia ma ka holo ʻana i kēia kauoha ma kāu kikowaena:
pip hoʻokomo i ka pyserial
Ke hoʻokomo ʻia ka waihona pyserial, hiki iā ʻoe ke holo i ke code ma ka mālama ʻana ma ke ʻano he .py file a laila holo i kēia kauoha ma kāu kikowaena:
kou_fileinoa.py

D2xx

He ʻelua ex maʻalahi kēia ʻāpanaampnā mea hoʻohana i nā API D2xx kumu.

E kiʻi i ka helu Port COM
E kiʻi i ka ʻike kikoʻī o ka hāmeʻa

Nānā i ka Ke alakaʻi o ka mea papahana D2XX no ka 'ike hou aku no keia mau API.

Loaʻa iā COM Port Number

ʻO kēia ex maʻalahiampHoʻouka ʻo ia i ka waihona d2xx, wehe i ka mea FTDI mua i loaʻa, loaʻa ka COM Port
helu me FT_GetComPortNumber a laila pani ia.
Loaʻa ka papa inoa code ma Pākuʻi D– GetComPortNumber.py.
Ke hoʻokō ʻia ka mea hoʻopuka e like me kēia:

E kiʻi i ka ʻike kikoʻī o ka hāmeʻa
ʻO kēia ex maʻalahiampHoʻouka ʻo ia i ka waihona d2xx a hoʻohana iā FT_Create Device Info List a me FT_Get Device Info Detail no ka loaʻa ʻana o nā kikoʻī hāmeʻa FTDI a papa inoa iā lākou.
Loaʻa ka papa inoa code ma Pākuʻi E – GetDeviceInfoDetail.py.
Ke hoʻokō ʻia ka mea hoʻopuka e like me kēia:

ʻEkolu ʻaoʻao Python Examples

Nui nā hale waihona puke ʻaoʻao ʻekolu a me exampke ʻike ʻia nei i ka hoʻonui ʻia ʻana o ka ʻōlelo papahana, ua helu ʻia kekahi ma ʻaneʻi akā ʻoi aku ka nui o ka loaʻa.

PyUSB

Hāʻawi ʻo PyUSB i ke ala maʻalahi i ka ʻōnaehana Universal Serial Bus (USB) o ka mīkini hoʻokipa no Python 3.
ʻO PyUSB kahi mea waiwai API, backend neutral Python USB module maʻalahi e hoʻohana. https://pyusb.github.io/pyusb/

pylibftdi

E ʻoluʻolu e hoʻohana kēia libftdi ʻAʻole ia he mea hoʻokele FTDI i kākoʻo ʻia akā hiki ke hoʻohana ʻia e hoʻokele i nā polokalamu FTDI.
ʻO pylibftdi kahi liʻiliʻi Pythonic liʻiliʻi i nā polokalamu FTDI. https://pypi.org/project/pylibftdi/

PyFtdi

Manaʻo ʻo PyFtdi i ka hāʻawi ʻana i kahi mea hoʻohana-space no nā polokalamu FTDI kaulana, i hoʻokō ʻia ma ka ʻōlelo Python maʻemaʻe.
https://pypi.org/project/pyftdi/

ʻAdafruit

Ua hana ʻo Adafruit i alakaʻi e hōʻike i ke ʻano o ka hoʻohana ʻana i kahi FT232H e hoʻopili ai i nā mea ʻike I2C a me SPI a me nā breakouts mai kāu PC desktop e holo ana i Windows, Mac OSX, a i ʻole Linux.

ftdi-python

ʻO kēia examphōʻike ʻo ia i kahi ʻanuʻu aʻe i ka hoʻokele FTDI IC mai Python e aʻo e pili ana i kā lākou hana.
https://iosoft.blog/ftdi-python/

ftd2xx ctypes Wrapper

ʻO ka ftd2xx kahi kāpili python maʻalahi a puni ka D2XX DLL mai FTDI me ka hoʻohana ʻana i nā ctypes. https://pypi.org/project/ftd2xx/

python-ft4222

ʻO kēia exampHāʻawi ka python i ka LibFT4222 pono e hoʻohana me FT4222H IC a hāʻawi i kahi API like me LibFT4222. https://pypi.org/project/ft4222/

Ka hopena

Hōʻike kēia ʻatikala ʻenehana pehea e hoʻohana ai i ka polokalamu Python me nā huahana FTDI me ka mea hoʻokele VCP a me D2xx a ua papa inoa i kekahi mau ʻaoʻao ʻekolu.amples.
