This week I spent time working on reading the pwm.c firmware we wrote for CMR’s firmware library, which uses a microcontroller in the same family as the Janktroller. The ST microcontroller datasheet was very helpful in identifying the different modes we need to set in the center-aligned PWM control firmware. I have also started researching battery solutions to power our motor and motor controller, such as looking into battery assembly clips (https://vruzend.com/ for example) and a potential BMS ASIC (http://www.ti.com/lit/ds/symlink/bq76940.pdf). As I have never actually designed a PCB before, I also spent some time this week going through the schematics of the Janktroller to familiarize myself with the parts selected and its circuitry. For the upcoming week, I anticipate spending further time with Deepak looking into the pwm firmware and reading this research paper about how we can start figuring out what we need for 6 step commutation (https://scolton-www.s3.amazonaws.com/motordrive/sensorless_gen1_Rev1.pdf)
