Waveshare ESP32-S3-Touch-AMOLED-2.06 (watch)

Port of Clawdmeter to the Waveshare ESP32-S3-Touch-AMOLED-2.06 smartwatch dev board. PlatformIO env: waveshare_amoled_206.

This board shares its display controller (CO5300), PMU (AXP2101), IMU (QMI8658) and I²C bus with the existing 2.16 / 1.8 ports, so the port mostly combines drivers already in the tree: the CO5300 display path from the 2.16 board and the FocalTech inline touch reader from the 1.8 board.

Hardware

Block	Part	Pins
Display	CO5300 AMOLED, 410×502, QSPI	CS=12, SCLK=11, D0–D3=4/5/6/7, RESET=8, TE=13
Touch	FT3168 (FocalTech), I²C @ 0x38	INT=38, RST=9
PMU	AXP2101, I²C @ 0x34	battery, USB VBUS
IMU	QMI8658, I²C @ 0x6B	INT=21 (rotation disabled)
RTC	PCF85063	on I²C bus
I²C bus	shared	SDA=15, SCL=14
Buttons	BOOT (Space/PTT) / PWR (screens, brightness, pairing)	BOOT=0, PWR=10

Fixed orientation (non-square panel — IMU auto-rotation is off). Display power comes from the AXP2101 rail and needs no explicit enable (same as the 2.16 board); if a future panel revision boots dark, see the commented AXP rail-enable block in power.cpp.

Display column offset

The CO5300 GRAM is wider than the 410 px active area, so the image needs a horizontal start offset or a band of uninitialised memory shows on the right:

#define CO5300_COL_OFFSET  22   // board.h — verified on this panel

Build & flash

pio run -e waveshare_amoled_206
pio run -e waveshare_amoled_206 -t upload --upload-port <PORT>   # COMx / /dev/ttyACM0 / /dev/cu.usbmodem*

Windows flashing gotcha

esptool's progress output crashes the upload on a non-UTF-8 Windows console (UnicodeEncodeError, cp1251). Force UTF-8 before running pio:

$env:PYTHONIOENCODING="utf-8"; $env:PYTHONUTF8="1"
pio run -e waveshare_amoled_206 -t upload --upload-port COM7

Host daemon notes

The device advertises as Clawdmeter (matching firmware/src/ble.cpp).

Two Windows-daemon fixes ship with this port:

daemon/claude_usage_daemon_windows.py scans for Clawdmeter (the upstream value Claude Controller never matched the firmware name).
Once the device is bonded as a BLE HID keyboard, Windows keeps it connected and it stops advertising, so a name scan can't find it. Set CLAWDMETER_ADDRESS to its BLE address to connect directly:
```
setx CLAWDMETER_ADDRESS "<AA:BB:CC:DD:EE:FF>"
```
The BLE address is the chip MAC (from esptool ... flash_id) +1.
