UART-I2C bridge for a small camera module supporting UART? #13

Closed araobp closed 7 years ago

araobp commented 7 years ago

I have been using ESP8266 as a main controller for the robot.

The problem is ESP8266's UART and all the other IO pins have already been occupied, but I want to add a small camera to the robot.

Idea:

[ESP8266]-- UART --[Arduino Uno]--sensors/actuators(5V)
[ESP8266]-- I2C --[bridge]-- UART --[camera module](3.3V)
[ESP8266]-- I2C --sensors(3.3V)

Do I use PIC as MCU for "ESP8266 sub-system" to add IO pins?

Future work.
