Elara, the systems technician, knelt in the mud, her tablet connected to the device’s brain: a humble PIC microcontroller. On her screen, the Flowcode flowchart sprawled like a map of a tiny, frantic city.
EEPROM was the chip’s stubborn, permanent scar. Write a number to it, and that number would remain, even if you unplugged the chip, threw it in a drawer for a decade, and plugged it back in. It was perfect for storing a last-watering time.
The basil was saved. And all because a few simple flowchart blocks knew how to write to a memory that refused to let go. flowcode eeprom
If no (the chip was brand new, or the EEPROM was blank), she placed a block: stored_time = 720 (that’s 12:00 AM in her internal clock units). A default.
At 3:16, the controller woke up, read its EEPROM, saw “3:00 AM” in address ‘0’, and went back to sleep until tomorrow. Elara, the systems technician, knelt in the mud,
It was a stupid, perfect demonstration. The chip had a soul now. A persistent, unwritten history etched into its silicon.
She let it blink five times. Then she yanked the power. Write a number to it, and that number
Inside, she placed a – EEPROM::Read . She set the address to ‘0’. This was the memory slot she’d dedicate to the watering time. The output went into a variable called stored_time .
