From the project

quick rp2040 based project for LMU's FSAE team to log haltech data and view it on anyones computer without haltech proprietary software

Status: Hardware architecture selected; firmware and breadboard validation not yet complete. Updated: October 21, 2026 Target: A practical demonstration for the FSAE electrical-team freshmen on October 22, 2026, at 8 PM.

- Microcontroller: Existing Raspberry Pi Pico / RP2040; no replacement development board. - CAN interface: Waveshare Pico-CAN-B (SKU 23775) with MCP2515, SIT65HVD230DR, 16 MHz crystal, 3.3 V logic. This replaces the user's existing 8 MHz MCP2515/TJA1050 breakout, which cannot be set to compliant 1 Mbit/s CAN timing. - Storage: Existing SPI microSD breakout, on a separate…
