HW1

HW1 assignment description ]]>here]]>. My homework folder ]]>here]]>.

This is my breadboard PIC32 circuit:


Test demo: a blinking LED (at 1 kHz), that stops when pushing and holding the USER pushbutton, and continues when releasings.

HW2

HW2 assignment description ]]>here]]>. My homework folder ]]>here]]>.

This homework is the first half of ]]>HW3]]>. We use ]]>Sparkfun Eagle Github libraries]]> to create our own libraries.

HW3

HW3 assignment description ]]>here]]>. My homework folder ]]>here]]>.

We create a PCB of our PIC32 circuit, 5cm x 5cm, with header pins at specific locations. Do all of the error checking, generate the Gerber files. This is my design:


HW4 - SPI DAC

HW4 assignment description ]]>here]]>. My homework folder ]]>here]]>.

Here's a schematic showing the connections between our PIC32 and this particular DAC (]]>the MCP4902]]>) using SPI communication. The DAC outputs on pins VOUTA (14) and VOUTB (10).


The DAC outputs:

10Hz sine wave on VoutA + 5Hz triangle wave on VoutB:


10Hz sine wave on VoutA + 10Hz triangle wave on VoutB:


HW5 - I2C pin expander

HW5 assignment description ]]>here]]>. My homework folder ]]>here]]>.

Here's a schematic showing the connections between our PIC32 and the MCP23008 I/O expander (]]>datasheet for MCP23008]]>) using I2C communication.



HW6 - LCD printing

HW7 - LCD control with IMU

Control the flowing bar on LCD screen by rotating LSM6DS33 breakout board, with I2C connection.
