Hey everyone,
I was looking at the CC1352P1 Launchpad schematic (Rev. C) and I realized that the I2C pull up resistors are on DIO5_SDA and on DIO22. While DIO21_SCL doesn't have any pull up resistor.
As far as I'm aware, I2C lines are supposed to have pull up resistors on both SDA and SCL.
So, was DIO22 switched by mistake for DIO21_SCL (see attached image bellow, I've colored DIO21_SCL and DIO22 for easy referencing)? Or is there a reason for this?
Thanks
