i2s mic

Alan worked on interfacing with an i2s mic.

After getting my logic analyzer setup, I try sampling the signals at 1Mhz. The resulting packets appear to have inconsistencies (in blue, “received…”) logic

Reading the datasheet, I see that the clock frequency is at max 4Mhz. logic

Setting the sampling frequency to 4Mhz seems to do away with the inconsistencies. logic

hall effect sensor

Dan worked on interfacing with a potentiometer and hall effect sensor mounted to RC control sticks.
