I have a strange result from the ADC:
Help wellcome.
Vref = EXT 1.25 V
SINGLEOFFSET = 0x8
SINGLEOFFSETINV = 0xA
SINGLEGAIN = 0x00
Problems:
1. From 0,625 to 1.25 OK. < 0.625 V allways 2048 ?!?
2. can't calibrate gain to 4096 mostly to 4079....4081
SINGLECTRLX - VREFSEL = 2
VREFATTFIX = 0
VREFFATT = 8
VINATT = 14
DVL = 0
FIFOOFACT = 1
PRSMODE = 0
PRSSEL = 0
SINGLECTRL - REP = 0
DIFF = 0
ADJ = 0
RES = 3
REF = 7
POSSEL = 0x87
NEGSEL = 0xFF
AT = 5
PRSEN = 0
CMPEN = 0
CTRL - WARMUPMODE = 3
SINGLEEDWAWU = 0
SCANDMAWO = 0
TAILGATE = 0
ASYNCCLKEN = 0
ADCCLKMODE = 0
PRESC = 0
TMEBASE = 5
OVSRSEL = 6
CHCONMODE = 0
Anybody any idea ?
Thanks
