DEVELOPMENT SEQUENCE¶

Tip

For each component, you need to ensure the dependent components are built first.

PROJECT CONSTRRUCTION
ACTUATION>LED
MAIN-CONTROL>EXIT (External Interrupt)
MAIN-CONTROL>TIMER
MAIN-CONTROL>RTC
MAIN-CONTROL>RNG
MAIN-CONTROL>SPI & ACTUATION LCD
MAIN-CONTROL>SPI & SD-CARD
COMMUNICATION>WIFI
COMMUNICATION>IOT
MAIN-CONTROL>I2C
PERCEPTION>MPU6050

ADDITIONAL NOTES¶

ADDITIONAL NOTES

The author has observed that the same code may work correctly at one time and cause frequent reboots at another time (preliminary suspicion is that some wild pointers in certain modules are causing this). It is recommended to completely clear the build folder and power cycle the development board before flashing.
