Onboarding

Below are some useful links for learning about how firmware works for the first time:

• What is a Microcontroller (MCU)? (7 minute YouTube video)
• CPUs, MPUs, MCUs, and GPUs (website)
• Memory Mapping and Registers (watch first 2 minutes 50 seconds)
  • The remainder of the video refers to the ARM Cortex-M4, which is used in the STM32G4 microcontroller family that some systems use (ex. EPS). Other systems, like OBC, use the STM32H7, which is based on the ARM Cortex-M7.
• Introduction to RTOS (12 part YouTube playlist)
• Compilation - How do computers read code? (12 minute YouTube video)
• Example of a remote sensing CubeSat mission (journal article)
