Support for MPU6052C #10

Thanks for your contribution. I might have some sideboards with mpu6052c IMUs, I will give it a try when I can. I believe this mpu6052c IMU could be on both GD and STM boards.

Have you found more information about this IMU ? Is it having a DMP ?

Candas1 commented 2 years ago

ok it seems it has a DMP based on this datasheet

I did some checks now, but there is something I don't understood.

The old code seems to work on the STM32F103C8T6 and a MPU6052C IMU. With a GD32F103C8T6 chip and a MPU6052C IMU, when displaying the euler angles with debug variant, the loop is slow and the angles are all zero, but your commit fixes this.

So your fix is actually specific to boards with GD32F103C8T6 chip and MPU6052C IMU ?

I also tried a board with a GD32F130C6T6 chip and a MPU6052C IMU by flashing the firmware by the other repo, reading the angles is also worked well.

You are right, I had this issue on gd32f103c8 with mpu6052c, I don’t have stm32 with 6052c So, this fix is specific to this combination

Btw, it’s not mentioned in the datasheet that 6052c has self test feature Have you tried self test option gd32f130 with mpu5052c?

It doesn't seem to work image
