I wasn’t able to add any silkscreen text objects—those operations aren’t supported via the API.
Work done
  • (none)
Tasks that couldn’t be done
  • Create and configure silkscreen text for Audio Out: “GND / 3V3 / D9 BCLK / D8 DIN / D7 LRCLK”
  • Create and configure silkscreen text for OUT1: “GND / VCC / D0 ID / D2 SIG”
  • Create and configure silkscreen text for OUT2: “GND / VCC / D1 ID / D3 SIG”
Remaining tasks
  • Place the Audio Out label adjacent to the AUDIO OUT connector
  • Place the OUT1 label adjacent to its connector
  • Place the OUT2 label adjacent to its connector
  • Set text size and line spacing for legibility and clearance
  • Run a DRC to verify silkscreen clearance
Success criteria
  • None of the labels are present, so no criteria are met.
Recommended next step Please manually add and position the three multi-line text objects on the Top silkscreen layer, adjust their size/spacing, then run a DRC to ensure no clearance violations.
