Introduction
The purpose of this assignment was to experiment with multiple other microcontrollers and to test their possibilities.
Methods
In the first tutorial we used an MPS430 microcontroller and the Energia
IDE. An HC-05 bluetooth module was used to comminicate with a
smartphone. An ssd1306 was also used to display text from the
smartphone.
In the second tutorial we used an STM32 microcontroller and the Cube IDE. An MPU6050 was used to acquire acceleration data. Results
MPS430:
Video 1: Running a simple blink program.
Figure 1: Testing the serial communication.
Video 2: Controlling
the blinking speed and brightness of 2 LEDs using a voltage divider and
potentiometer as analog inputs.
Figure 2: The minimum and maximum values of the potentiometer. The minimum is not
totally accurate because some resistance from the potentiometer is
still affecting the circuit even when turned all the way down.
Video 3: Using a phone
app to blink an LED over bluetooth.
Video 4: Using voice
commands to control an LED over bluetooth.
Video 5: OLED demonstration video.
Figure 3: Displaying
text only.
Figure 4: Entering
text in the bluetooth terminal.
Figure 5: The text
displaying on the OLED
screen.
STM32:
Video 6: Blinking an LED.
Figure 6: Displaying text over the serial monitor.
Figure 7: Echoing data over UART.
Figure 8: Recieving acceleration data from an MPU6050.
Discussion It
was very interesting to get to use something other than an Arduino for
once. The Cube IDE wasn't very user friendly but I'm sure it is only
because it has many useful features that we did not have time to really
explore.
