dma-baremetal SKILL.md skillA
dma-baremetal from outlinedriven/outline-driven-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add outlinedriven/outline-driven-development/dma-baremetal@git:20260905.fd53e99Pins git:20260905.fd53e99 in mdr.lock. Pin the fingerprint instead.

Use when configuring DMA channels, circular buffer mode, double buffering, memory-to-peripheral transfers, or DMA IRQ completion on bare-metal MCUs. Not for cache theory: use cpu-cache-opt.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DMA on bare metal ## Contract | Field | Bound contract | |---|---| | Trigger | A UART, SPI, or ADC transfer must run without the CPU, an audio or sensor stream needs a double buffer, or a DMA transfer does not start or delivers corrupt data. | | Authority | Read-only: emits stream configuration, interrupt handling, and cache-maintenance sequences to chat; the user places them in the firmware. Rollback is not needed because no file is written. No remote mutation. | | Side effect | Chat output only. | | Done | The stream and channel (or request line) are named from the reference manual request table, the register sequence configures the stream before enabling it, the interrupt handler clears the right flag register, and cache maintenance is stated for cores with a data cache. | ## Inputs - Target part and DMA controller type (STM32F4 stream and channel matrix, STM32L4 channel and request selection, STM32G0/G4/H7 DMAMUX, or another controller with its request table). - Direction: peripheral to memory, memory to peripheral, or memory to memory. - Peripheral data register address and data width. - Buffer address, length, and whether the buffer is single, circular, or double. …

How to install
mdr add outlinedriven/outline-driven-development/dma-baremetal@sha256:b7cd3ee228bf1c79The line at the top of this page pins the label git:20260905.fd53e99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
