Hi,
is the ICM-20469 a direct replacement for the obsolete MPU-9250?
I've compared all pins and they are all the same except for pin 1.
On the MPU the datasheet says to connect to VDDIO. On the ICM it says do not connect.
I'd like to not change the PCB routing unless necessary.
I'd appreciate any hints or comments!
thanks and best regards,
Mike
Happy Thanksgiving,
It looks like you should be able to make a direct swap without burning anything up! The firmware of the MPU-9250 will not run the ICM-20469. Pin 19 is also different as it is RESV on the MPU but it is int2 on ICM. Again, you should be able to simply swap out the chips and not have any electrical issues, but the firmware of the MPU will not run/control the ICM. If you run the firmware of the MPU on the ICM, I dont suppose you will have any electrical issues, but I dont think you will see any output from the ICM.
HI CYD,
Can you please tell me step by step procedure to configure ICM using SPI. I spent a lot of time and could get the Who Am I correctly.
Tell me the order in which registers are written ? what are the delay requirements between each SPI access etc
Do i need to toggle CSN pin after each 8 bits of read and write ?
Thank you
