Firmware Release V0.0.4

V0.0.4 firmware release.

This release includes App and Bootloader HEX assets.

Changes:

• App heartbeat values for secondary voltage, secondary current, and primary DC current now use the rounded average of all control-ISR samples collected during each heartbeat window.
• The averaging divisions run in the preemptible main-loop path; the control ISR only accumulates samples.
• The Host UI telemetry tooltip now stays inside the plot, omits the meaningless raw timestamp title, and uses the application tooltip styling.

Firmware Release V0.0.3

V0.0.3 firmware release. Includes App and Bootloader HEX assets. App adds the output V/I calibration workflow. Calibration is disabled by default and flash writes are locked while output is enabled.

Firmware Release V0.0.2

Public App firmware V0.0.2.

• App firmware only; Bootloader is not included in this release.
• Adds internal lower-MCU UVLO/OVP gate inhibit: VPRI OVP >32 V, AUX12 8-15 V, AUX5 3.7-6.5 V, MCU/VREF 3.3 V window 2.7-4.2 V.
• Protection trips after 30 switching periods of filtered abnormal supply values and auto-recovers after 10 normal periods; host protocol state and software enable remain compatible.
• Built with Keil MDK locally: 0 Error(s), 0 Warning(s).

Firmware Release V0.0.1

Public firmware V0.0.1.

• App firmware limits: CV 0-2200 V, CC 0-200 mA, CP 0-400 W.
• Protection thresholds: hardware OCP approx. 60 A, software OTP 70 °C.
• Both App and Bootloader were built with Keil MDK locally: 0 Error(s), 0 Warning(s).

Flashing: use ST-Link to flash the Bootloader/App HEX files separately, or flash the Bootloader first and then use BootLoaderHostUI to update the App HEX through WebSerial IAP.
