💖 HYDRASDR_GPIODIR 💖

okay bestie, welcome to hydrasdr_gpiodir, a User Command from the HydraSDR set of tools 💅 she's a lil tool that reads and reconfigures your device's GPIO pin direction settings, and she is not here to play nice.

✨ NAME ✨

hydrasdr_gpiodir — the tool that reads and reconfigures your device GPIO pin direction settings 🎀

🌸 DESCRIPTION 🌸

WARNING this tool reconfigures GPIO Direction IN/OUT and can destroy GPIO/MCU in case of mistake 😭

no like fr fr, read that again. this is real danger, not a drill. one wrong flag and your GPIO/MCU is gone gone. main character energy but for the wrong reasons. please be careful, i am begging 🫶

🦋 USAGE 🦋

  • -p, --port_no <p> — sets the port number <p> to [0,7] for whatever read/write operations come next ✨
  • -n, --pin_no <n> — sets the pin number <n> to [0,31] for whatever read/write operations come next 🌸
  • -r, --read — reads the port number / pin number direction, either the one specified by the last -n argument or, if you don't do that, all port/pin 💖
  • -w, --write <v> — writes the port direction specified by the last -n argument with value <v> which is [0,1], where 0=IN and 1=OUT 👑
  • -s [serial_number_64bits] — opens the board with the specified 64bits serial number 🔥

🌈 EXAMPLES 🌈

reading a direction off port 0, pin 12:

hydrasdr_gpiodir -p 0 -n 12 -r # reads gpio direction from port 0 pin number 12

reading everything, every pin, every port, the whole vibe check:

hydrasdr_gpiodir -r          # reads gpio direction on all pins and all ports

writing a direction, port 0 pin 10, value 1 aka output:

hydrasdr_gpiodir -p 0 -n 10 -w 1 # writes gpio direction port 0 pin number 10 with 1(output) decimal
