Description
After Shrimp Say, here comes Tortoise Say!
Tortoise Say is a revolutionary embedded system based on e-Ink technology. A drawn turtle eagerly displays a secret for you.
We provide you with a capture made using a logic analyzer of the communication with the screen while the turtle was displaying the flag. The screen used is a Waveshare 2.9inch e-paper V2.
The pins measured on the logic analyzer are:
D0:DIND1:CLKD2:CSD3:DCD4:RSTD5:BUSY
Will you be able to recover the turtle’s secret?
