Hi Folks,
I need a little help with this task. I want to read data from Ultrasonic distance meter which put out every 100ms serial data.
The protocol is here:
The captured data looks like:
My program trying to capture this data looks like:
obviously it doesn't work because my poor programming skills.Code:#CONFIG __config _CONFIG1, _FOSC_INTOSC & _WDTE_OFF & _PWRTE_ON & _MCLRE_OFF & _CP_OFF & _CPD_OFF & _BOREN_ON & _CLKOUTEN_OFF & _IESO_ON & _FCMEN_ON __config _CONFIG2, _WRT_OFF & _PLLEN_ON & _STVREN_ON & _BORV_19 & _LVP_OFF #ENDCONFIG ;MCU PIC 12F1840 DEFINE OSC 4 ; Use internal clock 4MHz OSCCON = %01101010 ; 4 MHz internal OSCTUNE = %00000000 ; Internal osc tunning TRISA = %100000 ; RA.5 input rest output ANSELA = %00000 OPTION_REG.7=1 ; disable internal pull-ups APFCON = %10001100 string var byte[16] ' Set receive register to receiver enabled DEFINE HSER_RCSTA 90h ' Set transmit register to transmitter enabled DEFINE HSER_TXSTA 24h DEFINE HSER_BAUD 9600 clear start: hSerin 100,start,[wait ($ff),str string\16] pause 100 HSEROUT [hex string,13,10] pause 500 goto start
I searched the forum to find something to point me how to capture these data but no success.
Can someone point me how to do that?
Thanks,
Louis
