Humorous Tales of Embedded Design with the LPC845M301JHI33Y

Story 1: The Case of the Overzealous Watchdog

Once upon a time, an embedded designer programmed an LPC845M301JHI33Y with a watchdog timer. However, they accidentally set the timer for a ridiculously short interval. As a result, the microcontroller kept resetting itself over and over again, leaving the embedded system in a perpetual state of confusion.

Moral of the Story: Always double-check your watchdog timer settings to avoid unintended surprises.

Story 2: The Battle of the Misbehaving Buttons

Another tale involves an embedded system that used the LPC845M301JHI33Y's GPIO pins for button inputs. However, the designer forgot to enable the internal pull-up resistors. Consequently, the buttons would trigger false interrupts whenever they were left floating.

Moral of the Story: Remember to properly configure GPIO inputs to prevent random interruptions in your embedded system.

Story 3: The Mystery of the Vanishing Data

In a third tale, an embedded system stored critical data in the LPC845M301JHI33Y's Flash memory. However, the designer failed to implement proper error checking during write operations. As a result, corrupted data sometimes ended up being written to Flash, leading to unexpected system failures.

Moral of the Story: Always verify the integrity of your data writes to prevent nasty surprises in the field.
