I have a code on the openmv that calculates the angle of an object compared to the camera. I want to use spi to send this data to an arduino, i tried to use one of the examples but it does not work the i want it to. Is there any example where i can easily use spi for a float in the while true.
Use our RPC library. It works like magic for this. The RPC library has some problems with USB and WiFi comms because of the latency but is perfect for SPI/I2C/CAN.
