SWIFI PCB status

All radios only tested on primary port (5pin / PFUP1)

  • 1 works well - used w/Spalding (9-17-09)
  • 2 7-2-09 : overvoltage event. dsPIC seems to have smoke holes. (has radio 00-20-4a-9f-99-86 : 10.0.0.7)
  • 3 works - but has trace damage - used w/Spalding (9-17-09)
  • 4 works - but has trace damage status unknown, 10-24-09 used w/LF
  • 5 works - but has trace damage : 7-3-09 programmed w/latest firmwire. 10-24-09 works (CEB has a lab 10-30-09)
  • 6 not working. damaged traces at edge of PCA needs to be fixed

software notes

  • hardware_config.h sets PLL MULT and SCALE to result in 14.74 Mhz * (74+2)/(5+2) = 40.024Mhz
  • DSPIC UARTs connect to SC/MC
  • SPI UART connects to WIPORTb
