Source code for OpenECU Subaru HC16 kernel
Here is a snapshot of the current OpenECU kernel for 68HC16Y5 processors used in USDM 02-05 WRXs. This kernel requires the Cosmic Tools IDEA CPU16 toolsuite (commercial) in order to assemble, but I thought I should share it anyway for reference purposes. If you find a free assembler for HC16 processors that works well, please let me know and I will try to migrate to that.
