💖 HYDRASDR_RF_FRONTEND 💖

okay bestie, welcome to the hydrasdr_rf_frontend(7) page — she lives in the User Commands section of the manual and she is, lowkey, your new favorite little tool for poking at the HydraSDR hardware. let's get into it 🫶

✨ NAME ✨

hydrasdr_rf_frontend — the HydraSDR RF Frontend Tool. that's her. that's the girl. 💅

🌸 DESCRIPTION 🌸

Query, Read, and Write device registers.

like… that's the whole serve. you can query them, you can read them, and yes queen, you can write them too. register girly pop. periodt. ✨

🎀 OPTIONS 🎀

  • -h — Show help. the classic "bestie I'm lost" button 🥺
  • -n, --register <n> — set register <n> as [0,0] for subsequent read/write operations. think of it as telling the tool which register you're about to mess with — everything after this points at <n>. it's giving "choose your fighter" 🦋
  • -r, --read — read register specified by last -n argument, or all registers. so if you set -n first, she reads that one. if you don't, she reads all of them. generous icon behavior 👑
  • -w, --write <v> — write register specified by last -n argument with value <v>, in the range [0,255]. yes the value is bounded, do not come for her with a 300, she will not be doing that 💀
  • -s serial_number_64bits — Open board with specified 64bits serial number. got multiple boards? pick your main character by her 64-bit serial ✨

🔥 EXAMPLES 🔥

okay here's the whole group chat in action:

<command> -n 12 -r    # reads from register 12
<command> -r          # reads all registers
<command> -n 10 -w 22 # writes register 10 with 22 decimal

see how it flows? -n picks the register, -r or -w does the thing. chef's kiss 😚👌

ngl the -n step is kinda the main character here — skip her and -r just reads everything. which is fine!! chaos is a vibe!! 🙈
