DIODES AP33772 USB PD Sink Controller Raspberry Pi I2C Interface alakaʻi hoʻohana

ʻO AP33772 Sink Controller, e hana ana ma ke ʻano he polokalamu protocol o USB PD3.0 Type C Connector-equipped Device (TCD, Energy Sink), i manaʻo ʻia e noi i ka Power Data Object (PDO) mai ka USB PD3.0 Type C Connector-equipped PD3.0 .XNUMX ka luna hoʻokō (PDC, Energy Source).

Hōʻike ka Figure 1 i kahi TCD, i hoʻopili ʻia me PD3.0 Sink controller IC (AP33772), i pili kino iā PDC, i hoʻopili ʻia me ka USB PD3.0 decoder (AP43771), ma o kahi
ʻAno C-i-Type C uwea. Ma muli o ka USB PD3.0 compliant firmware, e hele ka AP33772 a me AP43771 i ke kaʻina hana hoʻopili maʻamau USB PD3.0 no ka hoʻokumu ʻana i ke kūlana hoʻouka PD3.0 kūpono.

Hāʻawi ʻo AP33772 Sink Controller EVB i ka maʻalahi o ka hoʻohana ʻana a me ka versatility nui no ka mea hoʻolālā ʻōnaehana e noi i nā PDO mai ka USB Power Delivery Charger ma ka hoʻouna ʻana i nā kauoha i kūkulu ʻia AP33772 ma o ka interface I2C. Pono ka hoʻolālā ʻōnaehana maʻamau i ka polokalamu MCU e pono ai ka lako polokalamu kūikawā (e laʻa me IDE) a hiki ke lilo i kaʻina hana hoʻopau manawa.
ʻO ka ʻokoʻa, ʻo Raspberry Pi (RPI), kahi kamepiula papa hoʻokahi (SBC) e holo ana ma kahi Linux OS hoʻohana a hoʻolako ʻia me nā pine GPIO maʻalahi, hāʻawi i kahi ala pololei e hōʻoia i ka AP33772 Sink EVB e hana ana me kahi PD Charger. ʻO ka pahuhopu o kēia alakaʻi, ʻo ia ka hāʻawi ʻana i nā mea hoʻolālā ʻōnaehana i kahua kūpono e hoʻopau koke i ka hōʻoia polokalamu ma RPI a laila e hoʻokomo i ka hoʻomohala ʻana i kekahi MCU makemake e hoʻokō i nā koi mākeke huli wikiwiki.

Ma ke ʻano he palapala hoʻohui i ka AP33772 EVB User Guide, hōʻike kēia alakaʻi hoʻohana i kahi ala maʻalahi e hoʻokele iā AP33772 EVB me kahi RPI SBC ma o I2C Interface.
ʻO ke kuleana o ka poloka MCU i hōʻike ʻia ma ke Kiʻi 1 e hoʻopili me AP33772 e pāʻani ʻia e kahi RPI. Hoʻopili kēia alakaʻi mea hoʻohana i ka nui o ka wehewehe inoa a me ka ʻike hoʻohana e like me examples, Eia naʻe, no ka ʻike piha a hou loa, e ʻoluʻolu e nānā i ka AP33772 EVB User' Guide. (E nana i ka Helu 2)

Helu 1 - Ke hoʻohana nei kahi TCD maʻamau i ka AP33772 PD Sink Controller me ka I2C Interface e noi i ka mana mai kahi USB Type-C PD3.0/PPS Compliance Source Adapter.

Hiki i kekahi mana hou o RPI ke hoʻomalu iā AP33772 Sink Controller EVB ma o nā pine I2C. Hoʻohana ʻia kahi Raspberry Pi Zero 2 W (RPI Z2W) i kēia alakaʻi hoʻohana no ka maikaʻi o ke kumukūʻai a me ka versatility. Loaʻa iā ia ka formfactor liʻiliʻi loa ma waena o nā RPI āpau a ua hui pū ʻia me WiFi a me Bluetooth e hana ai i ka pilina uea me ka ʻole o nā mea hou. Mālama ʻo ia i ke kumu e like me ka AP33772 Sink Controller EVB Validation Platform kūpono loa.
Hiki i ka mea hoʻohana ke nānā i ka luna Raspberry Pi webkahua no ka ʻike hou aku (https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/)

Hoʻohui Pahu Hoʻopono a me ka Power up

Helu 5 hōʻike i kahi pilina piha a me ka hoʻonohonoho ʻana o ka Validation Platform. Pono ka mea hoʻohana e hahai i kēia mau ʻanuʻu:

Hoʻohui i nā pine SCL, SDA a me GND ma waena o RPI a me AP33772 EVB

Hoʻohui i ka 65W PD Charger a me AP33772 EVB me ke kelepona Type-C
E hoʻoikaika i ka RPI a me PD Charger.

Hoʻonohonoho lako polokalamu Raspberry Pi

ʻO Raspberry Pi OS

Nui nā ʻōnaehana hana like ʻole e kākoʻo ana iā RPI. Ma waena o kēia mau mea, koho ʻia ʻo Raspberry Pi OS no ka mea ʻo ia ka mea i hoʻohana nui ʻia a ʻōlelo ʻia e RPI official site.

Hoʻoiho i ke kiʻi OS a hoʻomākaukau i ke kāleka SD

Hoʻoiho a hoʻokomo i nā mea hana Raspberry Pi Imager ma kahi PC (https://www.raspberrypi.com/software/). E hahai i ka ʻōlelo aʻo e hoʻomākaukau i kahi Micro-SD i hoʻouka ʻia me ke kiʻi OS pololei (https://youtu.be/ntaXWS8Lk34/). E ʻoluʻolu e ʻoluʻolu e ʻōlelo ʻia ke kāleka Micro-SD o 32BG a ʻoi aku paha.

Hoʻokomo ʻia ʻo Raspberry PI OS

E hoʻokomo i ke kāleka Micro-SD i hoʻouka ʻia me ka mea kiʻi ma mua i loko o ka pahu Micro-SD o RPI. Hoʻohui i ka mana hoʻololi, ʻiole/pāpāpā, a me ka nānā HDMI.

No ke kākau ʻana i nā waiwai e pili ana i kēia mau papa inoa, e hoʻohana i kēia ma lalo o ka python3 environment:
SMBus.write_word_data(0x51, 0x28, 0x1a90) SMBus.write_word_data(0x51, 0x2a, 0x0ad6) SMBus.write_word_data(0x51, 0x2c, 0x0507) SMBus.write_word_data(0x51, 0x2e, 0x0296)

No ka heluhelu ʻana i nā waiwai, e hoʻohana i kēia ma lalo o python3 environment: SMBus.read_word_data(0x51, 0x28) SMBus.read_word_data(0x51, 0x2a) SMBus.read_word_data(0x51, 0x2c) SMBus.read_word_data(0x51), 0
ʻO nā huaʻōlelo hoʻihoʻi he mau huaʻōlelo 2-byte. Ma muli o ka mālama pono ʻana o nā kauoha i ka huaʻōlelo 2-byte, ʻaʻole pono nā mea hoʻohana e hopohopo no ka liʻiliʻi endian byte kauoha ma aneʻi.

Kākau iā RDO (0x30~0x33)

No ka hoʻomaka ʻana i kahi kaʻina kūkākūkā noi PDO, kākau ʻia ka ʻikepili 4-byte i ka RDO (Request Data Object) kākau inoa ma ka liʻiliʻi-endian byte kauoha. E like me exampe, e noi iā PDO3 me 15V a me 3A, e kākau ʻia ʻo 0x3004B12C i ka papa inoa RDO. E hoʻohana i kēia ma lalo o ka python3 environment:

SMBus.write_i2c_block_data(0x51, 0x30, [0x2c, 0xb1, 0x04, 0x30])
E ʻoluʻolu e nānā i ka Papa 9 a me ka Papa 10 o AP33772 Sink Controller EVB User Guide no ka ʻike kikoʻī maʻiʻo RDO.
Hiki i ka mea hoʻohana ke hoʻopuka i kahi hoʻihoʻi paʻakikī ma ke kākau ʻana i ka papa inoa RDO me ka ʻikepili āpau-zero:
SMBus.write_i2c_block_data(0x51, 0x30, [0x00, 0x00, 0x00, 0x00])
E hoʻihoʻi hou ʻia ka AP33772 Sink Controller i kona kūlana mua a pio ka hoʻopuka.
