Detailed Description

Sweeps DAC_B channel 0 in 12-bit normal-vref mode from 0 V up to about 3.3 V and back, stepping every 20 ms. dac_waveform drives a triangle over the same channel; this one is a deterministic DC ramp, so it exercises the runtime ra8_dac_b_init_configured and ra8_dac_b_write path with a predictable value at every step.

Nothing on the bench reads the analog pin – the rig has no ADC or voltmeter – so the unattended gate probes g_dac_b_demo_tick over SWD. That shows the firmware calling the DAC write API in a loop and not faulting; it does not show the pin voltage moving. Genuine validation needs a scope on DAC0.
