Sensor BMI088 and BMP388

Post by leonana69 » Tue Mar 31, 2020 12:46 am

I wonder is there any reason for changing I2C to SPI DMA way of reading sensors data in cf bolt?

The reason for that is that it might be possible to build a very small and powerful quadrotor using the Bolt. Then the latency between the sensor readings and motor output will be more important. The SPI has lower latency and therefore this was chosen. It adds some possible compatibility issues though so question is if it will be worth it.

Thanks for your answer!
