Hi,

Greetings of the day!!

I am using MCP3204 ADC interfaced with PIC18F4520. The reference voltage of MCP3204 is from voltage divider network of resistor and set to 500mV. Potentiometer value i ...

Hi all,

Thanks for your suggestions. I will check out the options which you have suggested.

Thanks,

Hi Mike,

I do not have oscilloscope to check the waveforms. Crying or Very sad

Hi,

Greetings of the day!!!

I am using driver files of MCP4921 to interface with PIC18F4620.
Compiler version is 4.119.

Everything working fine when I directly interface MCP4921 with PIC18F ...

Hi,

I am using ex_modbus_slave.c file of CCS compiler version 4.119. The code working fine. But I need to provide the selection of Baud rates for communication. Instead of fixed baud rate I need fl ...

Hi,

I am sorry for using wrong term. I mean to say multidrop connection. The problem was occurring because of improper voltage (reverse voltage i.e. VCC is connected to GND and vice versa) to bias ...

Hi,

I have a monitor which is programmed as modbus slave (RTU).

When I am connecting single device and checking the RS485 communication using Modbus poll and RS232 to RS 485 converter, it works ...

Hi,

Thanks for suggestions!!

I have re installed everything (CCS compiler as well as MPLAB IDE) and it starts working again!! Surprised Surprised

Thanks a lot for your help!!

Hi,
I am using MPLAB IDE version 8.60 and CCS compiler version 4.119 for programming of microcontroller PIC18F4520. I have working code which I am using since last 1 year. But suddenly I am facing a ...

Yeah... You are right ckielstra!!!

I was confused in MSB and LSB part. Now I understood that function.

Thanks a lot.

Thanks temtronic for quick reply!!!

I did some similar kind of calculations but failed to get expected results.

Anyways I'll try it again as per your suggestions.

Thanks,

Hi,

I am using driver file of mcp3204 and having some trouble in understanding "read_analog_mcp " function used in it.

Control bits calculated in code is not matching with datasheet fo ...

Hi,

I am working with a device which has RS-485 communication (modbus protocol).

I have used modbus_slave.c example file for this.

Now I have to interface this device with PLC. But while do ...

Yes!!! It worked!!!!

Thanks for your kind support.

Hello All,

I am using modbus_slave.c example file in which i am using FUNC_WRITE_MULTIPLE_REGISTERS.

It works fine when i am writing data from starting address 0001. But when i change it with so ...
