What are your parameters on PIC and PC?

I still deal with this problem Why Ethernet_getBytes() function reads only MAC header?

With Ethernet_getBytes() I can only read a MAC header and nothing else.

When I receive SNMP packet want to read the public name but Ethernet_getBytes() reads strange values.

Public name is located on 15th byte in UDP packet but Ethernet_getBytes() don not return proper value.

Example: How Ethernet_getBytes works?

DS1820 and DS18S20 are the same sensor, which have a 9-bit resolution while DS18B20 has adjustable resolution from 9 to 12-bit.

Can anybody help me, how to receive SNMP request with PIC. I send the SNMP request from my computer to agent (PIC), but I don't know how to receive it I'm using UDP for transport layer.
Does any function in mikroC PRO to do that?

Thanks Sobrietytest!

What a "->" operator mean?

Example:

variable1 -> variable2 = 0;

I would be very grateful too!

Program looks ok. Check your hardware if you connected properly. What value of pullup resistor are you using? Have you got +5V to DQ pin?

Are you using DS18B20 sensor now? If answer is yes than show us your procedure for setup resolution.

I think that the problem is here (in Write_Temp function). if ((temp and 0x8000) > 0) then text[0] = "-" temp2write = (not temp2write) + 1 end if Temperature value is transferred to the variable temp2write in that function. Change the temp variable to temp2write. if ((temp2write and 0x8000) > 0) the...

The problem is only in "-" now if I understand you? Temperature value is correct, right?

I assume that you use DS18B20 sensors. For these you need to set resolution to 9 bit.

Name for your SFR is AD1PCFG. Change ADPCFG to AD1PCFG and will work.
