# System Design

# Movement Detection
|
|
The unit has a MMA8652FC Accelerometer on the small sub board along with the STM32.
|
|
This is used for motion detection of the soldering iron.
|
|
|
|
# USB Disk
|
|
When the unit is plugged into the computer, it presents a FAT device to the operating system over the usb connection.
|
|
This is implimented using a ram buffer for the disk.

# Future improvements to be made
|
|
These features are things I would like to add to the firmware
|
|
|
|
* Use hardware PWM for driving the heating element.
|
|
* Use the sysTick hardware for timing of events
|
|
* Move all the settings to an on device menu system instead of usb link
|
|
* Move error codes into a unified struct
|
|
* Rewrite most of the OLED stack to not require hardcoded values
|
|
* Rework the modes of the unit to be neater
