Keep getting status error (-5) with my current wiring. I assume I have to change some things because the code I'm using is for the 9dof sensor MPU9250 and I'm using a MPU6500. Seem to have no problem getting I2C to work however for my project I want to use SPI.
Wiring is as follows:
• SDA / SDI: connect to MOSI. 11
• SCL / SCLK: connect to SCK. 13
• AD0 / SDO: connect to MISO. 12
• nCS: connect to chip select pin. Pin 10
Vcc to 5v
Ground to ground
Does anyone have an idea how i can get spi to work on my 6500 sensor
See code below.
