Nahanap mo na ba ang perpektong sensor ng I2C, napagtanto mo lang na pinipigilan ka ng nakapirming I2C address nito na gumamit ng maraming pagkakataon nito sa parehong bus? Huwag mag-alala; ang CJMCU-9548 1-to-8 I2C multiplexer ay narito upang i-save ang araw!
Binibigyang-daan ka ng multiplexer na ito na kumonekta ng hanggang 8 I2C device na may parehong address sa isang microcontroller. Nagsisilbing gatekeeper, niruruta nito ang mga command sa mga napiling I2C pin gamit ang iyong command, na ginagawa itong isang napakahalagang tool para sa pagpapalawak ng iyong I2C bus.
Paano ito Gumagana: Ang paggamit ng CJMCU-9548 ay diretso. Ang multiplexer mismo ay may default na I2C address na 0x70, ngunit maaari itong iakma sa anumang address sa pagitan ng 0x70 at 0x77. Sumulat ka lang ng isang byte na may gustong multiplex na numero ng output sa address na ito, at lahat ng hinaharap na I2C packet ay iruruta sa napiling port. Sa teorya, maaari kang gumamit ng hanggang 8 multiplexer, bawat isa ay nakatakda sa ibang address (0x70-0x77), na nagbibigay-daan sa iyong kontrolin ang hanggang 64 na device na may parehong I2C address.
Mga pagtutukoy:
- Interface: I2C IIC
- Chip: TCA9548A
- Mapipiling I2C Address: 0x70-0x77
- Trabahong Boltahe: 1.65V - 5.5V
- Max na Dalas ng Orasan: 400KHz
Kasama sa Package ang:
- 1 x TCA9548A I2C Multiplexer Breakout Board
Palawakin ang iyong mga kakayahan sa I2C gamit ang CJMCU-9548 multiplexer at walang kahirap-hirap na pamahalaan ang maramihang I2C device na may parehong address sa isang microcontroller.
