HYDRASDR_SI5351C(1)

💖 HYDRASDR_SI5351C 💖

okay bestie, gather round, because this one is literally the little register-wrangler of your dreams. it lives in the User Commands section of the manual (yes, section 1, the cool one) and its whole entire job is talking to the si5351c chip. no cap. 🎀

✨ NAME ✨

hydrasdr_si5351c — configure, read, and write si5351c control registers. that's it, that's the gig, and it ate. 💅

---

🌸 DESCRIPTION 🌸

Configure, read, and write si5351c control registers.

fr fr, that's the whole vibe: you poke registers, you peek at registers, you make the clock chip do what you want. main character energy only. 👑

🦋 OPTIONS 🦋

• -c, --config — prints out textual configuration information. like, it just tells you the tea about how things are set up. 🍓
• -n, --register <n> — sets the register number that the upcoming read/write operations will use. think of it as "bestie, we're going to register n next." 📍
• -r, --read — reads the register specified by the last -n argument. and if you didn't give an -n? it reads all the registers. iconic behaviour honestly. 👀
• -w, --write <v> — writes value <v> into the register specified by the last -n argument. yes, the last one. remember your -n, bestie. ✍️
• [-s serial_number_64bits] — opens the board with the specified 64-bit serial number. got a whole shelf of boards? this is how you point at exactly the one you mean. 🔍

🌈 EXAMPLES 🌈

reading register 12:

hydrasdr_si5351c -n 12 -r # reads from register 12

reading literally everything, no -n needed:

hydrasdr_si5351c -r
       # reads all registers

writing 22 (decimal, bestie, decimal) into register 10:

hydrasdr_si5351c -n 10 -w 22 # writes register 10 with 22 decimal

see how it flows? -n first, then -r or -w. the way that just works is so satisfying. 😭✨

heads up: those -n and -r / -w flags are a team. the read or write hits whatever register the last -n set, so order matters. keep them in order and you're golden. 🌟
