feat(packages): bump ArduinoCore-LPC8xx to 9e8be028 (named weak IRQ handlers) - #944
Conversation
…andlers) framework-arduino-lpc8xx#38: named weak IRQ handlers in the LPC845/LPC804 startup vector tables (SPI0_IRQHandler, DMA0_IRQHandler, ...) + weak NMI alias. Unblocks FastLED's ISR-driven drivers: DMA chunk-chain refill for SPI/UART async streaming (FastLED/FastLED#3453 follow-up) and a future WDT-labeled NMI wedge report. Zero behavior change for existing sketches — every named handler weak-aliases to the same Default_Handler. Checksum verified 2026-07-02 via curl | sha256sum.

Bumps the ACLPC pin past framework-arduino-lpc8xx#38: named weak IRQ handlers in the LPC845/LPC804 startup vector tables + weak NMI alias.
Downstream consumer: FastLED ISR-refillable async drivers (SPI streaming ping-pong refill via
DMA0_IRQHandler, async UART TX chunk chaining) — FastLED/FastLED#3453 follow-up, staged on FastLED PR #3550's branch.Zero behavior change for existing sketches: every named handler weak-aliases to the same
Default_Handler; the table is link-identical unless a consumer defines a strong override. ACLPC CI (all 9 board × toolchain builds) was green on the upstream PR before merge.ACLPC_COMMIT/ACLPC_VERSION/ACLPC_CHECKSUMupdated; checksum verified viacurl | sha256sum.🤖 Generated with Claude Code
