The CERN Mini LHC Display will be a prototype display board for the CERN Mimic Panel. Since the final LHC board will be large and therefore expensive, I'm starting with a mini version which can test the overall architecture but be smaller if it requires a re-spin.
Status
- 2025-05-10: Started putting BOM and schematic together
- 2025-04: Started putting design thoughts together
Design Thoughts
- discrete LEDs
- beam LEDs for B1/B2 (24 each, 48 total)
- beam IP LEDs (4 RGB, 12 channels total)
- TI LEDs (4 per beam, 8 total)
- dump LEDs (2 plus one RGB per beam, 10 channels total)
- cryo status wrapup LED (1 bicolour, 2 channels total)
- collimator status wrapup LED for each beam (2 bicolour, 4 channels total)
- BIS/SMP - beam permit, movables allowed in, stable beams, permit link (4 bicolor)
- energy display (4x 7-segment LEDs, 28 channels total)
- t(SB) display (hh:mm - 4x 7-segment LEDs plus a colon, 29 channels total)
- 4x TLC5955, one for each beam plus one each for energy display and t(SB) display
- 16x2 LED dot matrix displays for beam/accel status (built-in smarts, so no TLC5955 required)
MCU Needs
- I2C for link to controller
- SPI + 4 CS = 7 total pins for TLC5955s
- 19 I/Os + 4 CSs = 23 total pins for dot matrix displays
- ~32 I/Os total
