F411 flight control

Overview

Sensor: MPU6000+BMP280+QMC5883 Interface: PWM×6, uart×2, LED, buzzer, OSD, USB
Size: 30×30mm, mounting hole 20×20mm

Description:
1. The resistance detected by VBAT is 10K: 1K, There is no change in the schematic diagram, just solder 10 directly on the PCB.
2. After the test flight, the self-stabilization is very strong and the heading is very stable.
3. The BF firmware used is 3.5.7. After upgrading to a higher version, the magnetometer will not be able to detect it. (The manufacturer seems to have stopped producing the flight controller. It is probably because the subsequent firmware will not be maintained.)
4. There seems to be something wrong with the OSD. You can update the font. The OSD display in the Task list is also normal, but the image transmission cannot receive the picture. (I’ll work on it later, I’ll update it when it’s done...)

The house is rented, it's not big, there's no decent table in the whole room, just a wide window sill, barely used as a table, with a bunch of messy things piled up... I don't have many hobbies, just

I want to use KEIL3 software to implement fast interrupt in LPC2132. Has anyone done it before? Please give me some advice. Thanks in advance:loveliness:
A newbie asking for advice. Can't KEIL compile *.cpp?
Can't Keil uVision 4 use C++ to write programs? ? I added the *.cpp file and it still can't compile. Is it because KEIL can't compile or is there another problem?
