+# pico-picoemp-test-target
+
+With this simple program, a Raspberry Pi Pico (RP2040) can be used as a test target for an EMFI (Electromagnetic Fault Injection) tool like the PicoEMP.
+
+Initially the Raspberry Pi Pico's LED will blink slowly.
+
+You can then test your EMFI tool on the RP2040, e.g. in the "pin 1" corner that's marked with a dot.
+
+* If fault injection is successful, the LED will blink faster.
+* If fault injection causes the RP20240 to hang, the LED will permanently stay on or off.
+
+After the test, just power cycle the Pi Pico.
