Progress update, 18 Jul 2026

Updates are bullet-point summaries generated with AI from my commits and build notes, then checked by me. Project articles and learning notes are written by me.

The register diagnostic now prints each i2cRead return code next to the value. On the bit-banged bus, a zero-initialised buffer made 00 indistinguishable from a failed read.
Tracked a dead left motor to uninitialised TIM8 config structs. Channels 1 to 3 read the unset complementary-output fields and channel 4 does not, so only the right motor (channels 3 and 4) ran. Value-initialising the structs fixed it.
Swapping the motor connectors could not separate hardware from firmware. Flashing Yahboom’s vendor image onto the same board did: both wheels drove.
