To the list of features I am now happy to add the ability to send telemetry via the video signal, mainly to use to send the aircraft location to an antenna tracker. This functionality has been working well on my older hack board and just today got it running on the aerflite FC. This makes the FC plug and play with my old antenna tracker. Since video transmitters are limited to 25 mW in UK some form of tracker is essential to get any range. A gps tracker is especially suited to thermal soaring which is my main interest, since the plane is often high overhead.
Now just waiting for my wing to arrive and hope to build it and get the FC flying. The EEPROM seems to be working well and this shaves a fair bit off the price compared to FRAM . The equivalent FRAM are about the same price as the Microcontroller used. There is a wait as the eeprom params are loaded but I think it is acceptable at start up. The BMI160 imu seems very smooth and responsive. All the other budget sensors seem to be working well, so it look like the cheaper components havent compromised performance unacceptably, and this board is designed to be cheap and fun and at the moment I am quite happy with the outcome
I am probably now going to ditch the CAN on this board. I can use one mcu pin saved to add another RCOUT for a total of 7. The other pin will come in useful too. I am going to investigate differential I2C which looks like an interesting alternative to CAN.
