Update 8 voltage divider packages for new ResistorVoltageDivider API by napowderly · Pull Request #447 · atopile/packages

napowderly · 2026-04-03T00:00:46Z

Summary

Migrate all packages with voltage dividers to the new ResistorVoltageDivider API (atopile 0.14.x discrete sampling solver). All 8 packages build successfully with both default and usage targets.

API Migration

Old	New
`.r_top`	`.chain.resistors[0]`
`.r_bottom`	`.chain.resistors[1]`
`.power`	`.ref_in`
`.output` / `.output.line`	`.ref_out` / `.ref_out.hv`
`.max_current`	`.current`

Additional Fixes

from "regulators.ato" import X → import AdjustableRegulator (file-path imports no longer resolve; AdjustableLDO/Buck not in stdlib allowlist)
Deprecated .vcc/.gnd → .hv/.lv
assert x is <literal> → assert x within <literal>
cap.power ~ power_out → bridge connections (avoids solver alias cycles)
Old pin names p1/p2 → unnamed[0]/unnamed[1] or bridge connections
Cross-parameter inequalities replaced with explicit bounds (simple solver compatibility)
Duplicate trait has_part_removed removed (st-ldk220 usage)

Test plan

All 8 packages build with ato build (both default and usage targets)
Picked resistor values verified against datasheet reference voltages
Publish packages to registry

Migrate all packages using voltage dividers to the new API introduced in atopile 0.14.x with the discrete sampling solver. Bump versions (minor) and set requires-atopile to ^0.14.0. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Copy the (at X Y angle) coordinates from the old r_top/r_bottom footprints to the new chain.resistors[0]/chain.resistors[1] footprints so board layouts are preserved. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The chain.resistors[0/1] footprints were at origin (0,0). Placed them adjacent to the converter package at (157, 103-104). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…istors - st-ldk220, ti-tlv75901, ti-tps82130: "0402" -> "R0402" for divider resistors - ti-tps82130: rebuild picked parts with R0402 footprint - ti-tps63020/default: place divider resistors near IC Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

These features (TRAITS, FOR_LOOP, BRIDGE_CONNECT, MODULE_TEMPLATING) are now first-class ato v1 language features and no longer require pragma gates. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Changes docker-tag from "main" to "latest" so builds use the latest stable release (currently 0.15.0) rather than unreleased main branch code. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Remove obsolete 0201, 0603, and miscellaneous parts (connectors, switches, antennas) that are no longer needed. Update footprint and ato files for retained parts. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Delete auto-picked resistors/capacitors across all 8 packages - Regenerate IC, inductor, and diode parts with fresh checksums (fixes is_auto_generated checksum mismatch from pragma removal) - Replace deprecated has_single_electric_reference_shared with has_single_electric_reference - Rename gnd_only parameter to ground_only - Fix _package suffix mismatches in ti-tps54560x imports - Replace bridge connect operators with explicit pin connections for raw component parts in ti-tps54560x Packages: ti-tps82130, ti-tpsm863257, ti-lv2842x, ti-tps563201, ti-tps54560x, st-ldk220, ti-tlv75901, ti-tps63020 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Remove unused imports, sync README.md with usage.ato content, fix deprecated `assert is` syntax, and clean up commented-out auto-generated trait with dangling import. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Sync README code blocks with actual usage.ato: remove stale pragma lines, fix import order, update assertion syntax, and match voltage values for ti-lv2842x, ti-tps54560x, ti-tps63020, ti-tps82130, and ti-tpsm863257. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Replace EasyEDA's non-PDF URL (ti.com/cn/lit/gpn/tlv759p) with the direct PDF download (ti.com/lit/ds/symlink/tlv759p.pdf). Update auto-generated checksum accordingly. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

ti-tps82130: - Remove saleae-header dependency (only used by disabled dev board target) - Remove unused layout directories (development_board, dual_banana_connectors, ti_tps82130_with_test_points) - Remove unused imports (Diode, ElectricPower, Inductor, ResistorVoltageDivider) - Add missing has_datasheet trait to HRE capacitor parts to prevent build warnings about library part updates ti-tlv75901: - Vendor TI datasheet PDF (downloaded from corrected URL) - Updated KiCad PCB datasheet property from build Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Override feedback divider current to 10-100uA in usage.ato instances to avoid very high resistance values where LCSC/EasyEDA has sparse footprint coverage. The base module keeps 1-100uA for maximum flexibility when no output voltage is set. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Rebuild usage layout to fix frozen PCB diff (datasheet URL changes). New resistor parts vendored from solver picks with tighter feedback divider current (10-100uA in usage instances). Remove unused ResistorVoltageDivider import. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Reduce usage.ato to one 24V→3.3V regulator (avoids solver picking obscure resistor values with sparse EasyEDA coverage) - Rebuild layouts for ti-lv2842x, ti-tps54560x, ti-tps563201, ti-tps63020 - Fix ti-tps82130 comment formatting (linter) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
