An adapter allow HuskyLens communication with LEGO Mindstroms EV3 (support SPIKE/RI).
The EV3/SPIKE/RI using LEGO UART protocol to communicate with sensors, and HuskyLens provide I2C and UART to transmit data, so we use an Arduino as an "Translator", to convert HuskyLens data to LEGO UART format.
We use an Arduino Pro Mini, and a simple PCB to connect HuskyLens pins and EV3 ports.
- Arduino Pro Mini 5V, 16 MHz with baud 115200 for EV3
- Arduino Pro Mini 3v3, 8 Mhz with baud 57600 for SPIKE/RI
- HuskyLens and Arduino communicate with baud 9600 (swuart)
Using avrdude or XLoader to upload firmware hex file to your Arduino Pro Mini, if you using ICSP to program your arduino, you can choose "_with_Bootloader" one hex file to programming to keep the bootloader there.
For XLoader users: You can add this line into device.txt to upload bin file to Pro Mini. (Tested, works fine.)
"Pro mini(ATmega328);m328p;stk500;57600;"
