Member Data Documentation

unsigned char _EDR_tkrTower::id

Tower number

unsigned char _EDR_tkrTower::lecnt

Total number of layer ends with active strips. By implication, this is also the number of TOTs. This number is just lecnts[0] + lecnt[1]

unsigned char _EDR_tkrTower::lexycnts[2]

Count of number X (0) and Y (1) layer ends with active strips

unsigned short int _EDR_tkrTower::totOffset

Byte offset to the first TOT in the raw TKR record This number can be used to derive the total number of active strips on this layer, see the inline EDR__tkrTowerNstrips

unsigned short int _EDR_tkrTower::len

Length in bytes of raw record. This does not include any end of record padding,

unsigned int _EDR_tkrTower::xyLoHiCnts

Count of Xlo, Xhi, Ylo, Yhi layer ends struck. This is packed from MSB to LSB as Xlo | Xhi | Ylo | Yhi

int _EDR_tkrTower::layerMaps[2]

Bit map of the struck x,y layers, LSB = layer 0, Note that if one uses the FFS function to scan this list, either

1. The returned value should be transformed as n ^= 31 or
2. The following construct should be used

               EDR_tkrLayer *layers = tkr->twrs[ntwr].layers[31];
               int                n = FFS (tkr->twrs[ntwr].layerMap[xy]
               EDR_tkrLayer *layer  = layers - n;

int _EDR_tkrTower::playerMaps[2]

Scratch pad copy of the layer maps used by pattern recognition

const unsigned int _EDR_tkrTower::rsvd[2]

This is needed to keep the structure the same length as it was when loHiLayerMaps was an active member

EDR_tkrLayer _EDR_tkrTower::layers[EDA_TKR_K_LAYERS_PER_TOWER]

< Bit map of struck layers; 0 = Xlo, 1 = Xhi, 2 = Ylo, 3 = Yhi Layer descriptions
