Open source AutoQuad flight control based on i.MXRT1052

This is an original work by netizen jiezhi320 who participated in the RT-Thread application competition. In 2015, jiezhi320 made a version of hardware based on stm32f405rgt6. However, due to the high CPU usage of the UKF algorithm, the author migrated it to imx-rt1052, in order to leave enough resources for everyone to develop in-depth for model friends.
