Glove Prototype Assembly

[digitaldanny]

Describe the solution you'd like

• Build 2 more flex sensors using the method described in #36 and #22.
• Sew the flex sensors and IMU breakout board to a glove.
• Mount the glove PCB to a forearm brace and make appropriate connections to the battery, HC-05 breakout board, and IMU breakout board.

Having some problems with the power output of the buck/boost converter. There is a periodic noise on the output with an amplitude of about 100 mV. Switching the 1 uH inductor with the 1.5 uH inductor made some improvements to what I was originally seeing.

TODO - Add screenshot of the oscilloscope waveforms here.

Also having problems with the HC-05 module. The UART Rx interrupt never happens when attempting to read from the NAME register in command mode. After hooking it up to the logic analyzer, I determined that the issue is on the HC-05 side rather than the PCB. My tx message sends, but I do not receive anything back from the module.

When running the LCD demo, I noticed the animations played slower. Need to double check that there are not any problems with the crystal oscillator.

If the oscillator frequency is wrong, this might be why my HC-05 is not working. Double check the baud rate of the uart TX messages.

This screenshot shows when the power switch is flipped OFF. The MSP_3V3 power rail slowly discharges instead of switching off immediately. This might be okay since this rail is only powering the MSP432, which will turn off after the initial quick dropoff to 2V.

I tried adding pulldown resistors to the buck/boost input and output, but this did not affect anything.
