mpu9250 gy-91 stm32 hal spi

mpu9250's Introduction

MPU9250

MPU9250 (GY-91) driver for STM32 with HAL using SPI (spi1 by default).

Setup

Define GY_CS pin in STM32CubeMX that will be used as Chip Select for the device, or pick the one you need in the MPU9250_Config.h.

How To Use

Use MPU9250_Init() to initialize the device.

Then use this to retireve the raw data:

int16_t AccData[3], GyroData[3], MagData[3];
MPU9250_GetData(AccData, GyroData, MagData);

printf("%08d;%08d;%08d;%08d;%08d;%08d;%08d;%08d;%08d\n",
  (int16_t)AccData[0], (int16_t)AccData[1], (int16_t)AccData[2],
  (int16_t)GyroData[0], (int16_t)GyroData[1], (int16_t)GyroData[2],
  (int16_t)MagData[0], (int16_t)MagData[1], (int16_t)MagData[2]);

mpu9250's Issues

how can use aux-iic to read data from bmp280

GY91 is MPU9250+BMP280 10DOF sensor

Magnetometer Register Issue

As seen in the code you have stored External Sensor data into Magnetometer array: MagData
But actually as per my understanding we need to read AK8963 Register HXL
Please can you help me in understanding this.

SPI read not working on MPU-9250 , STM32g4f4re

STM32 SPI READ NOT RIGHT

Hi,In function MPU_SPI_Read(), line:
HAL_SPI_Receive(&MPU9250_SPI, pBuffer, NumByteToRead, HAL_MAX_DELAY);
need read one more byte ,as spi read dump byte , pBuffer[1] as first read byte.
Please check it ,Thanks.

Extending to read from BMP-280

Would it be possible to extend this to also read the barometer data over SPI?

No license

Hello, I'm a computer science student, and i want to use this library in my student project, but i can't see any license here. Could you add some license like MIT? Thanks in advance :)
