Lab 1 peer reveiw
During the lecture henrik gave he used a 3 head jumper for BOOT0. D+ and D- on the USB are bi-directional. On your PMW you have a power source connected to the NCS, it should instead be connected to the MISO. Page 14 in the PixArt datasheet: Also the pins 9-13 are all right now set as input to the PMW, but some of them should be output. Page 5 in the PixArt datasheet: Also double check all the labels for the MCU, so that you get output/input correct.
