cpcap_batter..._accumulated(9)

✨ NAME ✨

okay so bestie, this is cpcap_batter..._accumulated(9) from the Kernel API Manual, and it's literally just one function: cpcap_battery_read_accumulated — it reads the cpcap coulomb counter 💅 that's the whole vibe, no cap.

---

🦋 SYNOPSIS 🦋

int cpcap_battery_read_accumulated (struct cpcap_battery_ddata *ddata ,
struct cpcap_coulomb_counter_data *ccd );

like, that's the whole call, periodt ✨

---

🎀 ARGUMENTS 🎀

• ddata — the device driver data 🌸 honestly the main character struct here.
• ccd — the coulomb counter values 🫶 that's where the numbers land.

---

💖 DESCRIPTION 💖

so this whole thing is based on the Motorola mapphone kernel function data_read_regs. 🔥 and like, if you actually look at the registers? the coulomb counter is lowkey similar to the coulomb counter in TWL6030. highkey the same energy, iykyk. 👑

if you wanna go deeper, check "TWL6030 Gas Gauging Basics (Rev. A) swca095a.pdf for "10 Calculating Accumulated Current" — that's the chapter you want, bestie 📄✨

okay so important caveat time 🙈 swca095a.pdf literally instructs you to stop the coulomb counter before reading so the values don't change mid-read. but the Motorola mapphone Linux kernel does not do that 💀 so let's just assume they've already verified the data produced is correct. that's the assumption we're rolling with, ngl.
