h1. Attendees:
| Steve Smith | John Dusatko | Hamid Shoaee |
| Bob Simmons | Cecile Limborg | Michael Cecere |
h1. Agenda:
# uController based design
# IOC Implications
# Project Timeline Overview
h1. Presentation Materials:
[MicroController Electronics, M. Cecere|http://lcls-dev:4298/tiki-download_wiki_attachment.php?attId=48] (PPT Format)
h1. Minutes:
# Discussed using microcontroller in place of FPGA
## Microchip PIC processor, 40 MHz, 40 MIPS
### also supports TCP/IP
# Don't need [MPS dynamic threshold|http://www-ssrl.slac.stanford.edu/lcls/PRD/1.1-511-r0_LCLS_InterimMPS_ICD.pdf] setting from IOC
## microController lets us do ratiometric 10%, 50% calculations for Comparator mode
## might need for Over-Charge threshold setting on future toroids
# Still use Akre's fast ADC board for waveform acquisition
# Ethernet capabilities of PIC processor could become main comm link with IOC
## If fast enough for 120Hz update rate
# Bob simmons has used a PIC18 controller in a similar project
h1. Action Items:
# *M. Cecere:* Any Toroid cables that are in comparator mode appear in seperate racks?.
# *M. Cecere:* Develop Project Timeline with assistance
# *M. Cecere:* Estimate PIC performance, from ICE and Bob Simmons work
# *M. Cecere:* Check with Ron Akre on availability of his 4-channel board
# *M. Cecere:* Develop PIC flowchart and timing charts
# *M. Cecere:* Develop Materials for CDR next wed. May 24
