Well, I think I figured out the work of CRC error correction. So all in all I can use another polynomial in my project, not just that suggested by maxim. In transmitter part I send temperature code with additional digits (remainder) which came from dividing temperature code with generating...
Hi, yeah, I read it. Still can't figure it out. Could someone please show an example of this with incoming temperature bits like that: 0000 0111 1101 0000 (+125 degrees). Polynomial is X^8+X^5+X^4+1. First LSB is checked and then MSB. Maybe an example will clear it up.
Thank you for the answer. Well, I know it's optional and It works good without it, however want to build a radio thermometer and use CRC as additional thing in my final year project.
Hi, first of all Merry Christmas to you all. And I would like to ask about CRC in DS18B20. I made project with a 8051 and DS18B20, however I didn't use CRC because it was tricky to understand, how it works. I would like to implement this error correction in my final year project and I am asking...
Thank you, you mean like this? By doing so, my program freezes and I have to cancel it.
RAM equ 0000H
ADC_CONV equ 4000H
ADC_READ_HBE equ 8000H
ADC_READ_LBE equ 0C000H

Thank you very much good people!
I deleted the LCALL READ statement, and the program took all of the 100 samples.
I also added two more lines:
MOV DPTR, #ADC_READ_HBE
MOVX A, @DPTR
MOV DPTR, #RAM
MOV DPH, R2 (This one)
MOV DPL, R3 (And this one)
MOVX @DPTR, A
INC DPTR...
Hello, I am having problem with program written with KEIL: *** error 65: access violation at I:0x81 : no 'write' permission. Can't find sollution myself, please, could you help?
This program takes info from ADC and writes it to RAM (100 samples). These is also delay routine with a...
