It took some adjusting with a flathead screwdriver to dial it into under 10um error, but seems stable and should be fine for initial testing despite just being a press fit at the moment. +Before + ## HTMSTMAA Week 8 - 4/22/21 This week I managed to get the LDC1101 configured and up and running, and in the process switched over to an [STM32L432KC](https://www.st.com/en/microcontrollers-microprocessors/stm32l432kc.html) in Nucleo form, which is a cortex M4 clocked at 80 MHz with an FPU, and most importantly gives straightforward access to timer peripherals (my struggle last week was that after configuring a timer on the Feather M4, it seemed to promply get overwritten by Arduino's USB peripheral). Ultimately this will make more sense considering I would like to integrate this sensor into a closed loop stepper driver that I also built on ST hardware. diff --git a/images/RpInterpolation.png b/images/RpInterpolation.png new file mode 100644 index 0000000000000000000000000000000000000000..5baa663d8af459239743afd7df379ac72ca1ed00 Binary files /dev/null and b/images/RpInterpolation.png differ diff --git a/images/encoderTesting1.png b/images/encoderTesting1.png new file mode 100644 index 0000000000000000000000000000000000000000..cee2202eeae9d2a0392689ac427ceb2a5260f6c6 Binary files /dev/null and b/images/encoderTesting1.png differ diff --git a/images/impedanceTest.png b/images/impedanceTest.png new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391
