Other Parts Discussed in Thread: PGA460
Hello,
Right now I am working on PGA460 EVM board and I also get correct distance measurement from Energia sketch GetDistance code. with these configurations,
byte fixedThr = 1; // set P1 and P2 thresholds to 0=%25, 1=50%, or 2=75% of max; initial minDistLim (i.e. 20cm) ignored
byte xdcr = 1; // set PGA460 to recommended settings for 0=Murata MA58MF14-7N, 1=Murata MA40H1S-R
byte agrTVG = 1; // set TVG's analog front end gain range to 0=32-64dB, 1=46-78dB, 2=52-84dB, or 3=58-90dB
byte fixedTVG = 1; // set fixed TVG level at 0=%25, 1=50%, or 1=75% of max
byte runDiag = 0; // run system diagnostics and temp/noise level before looping burst+listen command
byte edd = 0; // echo data dump of preset 1, 2, or neither
byte burn = 1; // trigger EE_CNTRL to burn and program user EEPROM memory
byte cdMultiplier = 1; // multiplier for command cycle delay
byte numOfObj = 1; // number of object to detect set to 1-8
byte uartAddrUpdate = 0; // PGA460 UART address to interface to; default is 0, possible address 0-7
bool objectDetected = false; // object detected flag to break burst+listen cycle when true
bool demoMode = false; // only true when running UART/OWU multi device demo mode
bool alwaysLong = false; // always run preset 2, regardless of preset 1 result (hard-coded only)
double minDistLim = 0.1; // minimum distance as limited by ringing decay of single transducer and threshold masking
uint16_t commandDelay = 1; // Delay between each P1 and Preset 2 command
uint32_t baudRate = 9600; // UART baud rate: 9600, 19200, 38400, 57600, 74800, 115200
Actually, I'm using the 40Khz Transducer, So my problem is designing the cone for my Sensor when I am using PGA 460 IC for ultrasonic sensing unit. so there are any guidelines for Cone designing for actual measurements. I want to use in Smart sensor For Dustbin. everything is complete in our project except casing of sensor and we're stuck in designing of cone.
here is some link of sensors which type we're making and we want...

Thanks in advance.
