Open source AutoQuad flight control based on i.MXRT1052

Overview

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.
The hardware board is based on the Wildfire 1052 mini development board. The sensors are ready-made modules purchased from Majia, which are fixed on the development board in the form of flying wires (a small board suitable for flight control will be redesigned later).
Each sensor is connected to the IMX- On SPI3 of RT1052, time-sharing operation is performed. The PWM signal used to control the ESC uses the AB channels in PWM1 and PWM2 on the master control. The GPS module is an independent unit and is connected to the serial port 5 of the main control through the serial port.
