I'm trying to run the Rust GPIO example on the T2G Body Entry Starter Kit. I seem to have the toolchain set up correctly, the code compiles, and it seems to flash but immediately halts on the microcontroller. I'm using the ARM GNU toolchain v13, the attached Ope...

For example, before entering Deep Sleep, a variable (e.g. BOOL sleep_flag) is assigned FALSE(0). When my board wakes up, sleep_flag is assigned TRUE(1); Otherwise, Is it possible to assign two different interrupt handlers to one GPIO pin? For instance, when rising_edge interruption fir...
