What does /volt-driver do?

It writes embedded device drivers (I2C, SPI, BLE GATT, MQTT, Modbus) with a HAL abstraction so they are portable across hardware revs and unit-testable on a host.

AI Embedded Device Driver Generator

Embedded drivers tend to be one-shot writes coupled tightly to the specific chip. The driver works on the eval board and breaks when the schematic changes for the next hardware rev. The driver works on the original MCU and has to be rewritten when the team switches part. The bus access is hardcoded so unit testing requires the actual hardware. Each of these is a structural choice the team made implicitly during the demo and pays for at productization.

The /volt-driver skill writes drivers with a HAL abstraction layer so the driver is portable across hardware revs and unit-testable on a host. I2C and SPI sensor drivers, BLE GATT services, MQTT clients, Modbus RTU handlers, each with the bus operations behind an interface and interrupt-driven I/O for performance.

What the driver includes

HAL interface for the bus operations (read, write, transfer). Interrupt service routine for non-blocking access. State machine for protocol handling. Error handling per response code. Unit tests against a mock HAL so the driver runs on a host without hardware. Documentation of the chip-specific commands implemented.

Tonone's /volt-driver skill writes embedded drivers with HAL abstraction, interrupt-driven I/O, and unit testability.

/volt-driver

Writes a device driver or protocol handler with a clean HAL abstraction layer: I2C and SPI sensor drivers with interrupt-driven I/O, BLE GATT service implementations, MQTT client with reconnection logic, or Modbus RTU handlers. Designed to be unit-testable and portable across hardware revisions.

/volt-firmware

Scaffolds a complete embedded firmware project for a target MCU: RTOS task structure with stack size planning, peripheral initialization sequences, power management state machine, communication stack (BLE, MQTT, or serial protocol), OTA update client, and CI build configuration. Available for ESP-IDF, STM32 HAL, Zephyr, and Arduino frameworks.

/volt-power

Analyzes the firmware power budget: maps all sleep modes and their wake sources, audits power state machine transitions for missing low-power states, measures radio duty cycles for BLE and WiFi including advertising intervals and connection parameters, and estimates battery life under different usage pattern scenarios.

When a battery-powered device is not meeting its b…

/volt-ota

Builds a complete OTA firmware update system: dual-partition A/B storage with partition manager configuration, firmware image signature verification to prevent unauthorized updates, download with resume capability on connection loss, atomic partition swap, and automatic rollback if the new firmware fails to boot successfully.

When devices are deployed in the field and need re…
