I'm using CCS version 5, but the Modbus library is version 4, since the drive Modbus version 5 did not compile at all.

I'll do some tests by sending and receiving something directly on the micropro ...

Good morning Ttelmah

I did a routine with the same hardware running as Master. And when sending commands it returns normally. I used the slave Modbus Poll to see if the data was coming and everythi ...

I'm using Modbus slave routine example for testing, but it does not work. I'm using the PC Modbus Poll. The PC transmits and not get anything back. The PC program only sends and PIC returns nothing.
...

Good afternoon.

What I could see in the routine of Slave she lock in "while (! Modbus_kbhit ());" Don`t go out of this condition. Sending data however, gets nothing. If this part of the r ...

Good afternoon!
For some time I have been trying to use the examples of Modbus that come with the CCS. The ex_modbus_master until it is working fine, however the ex_modbus_slave not work at all. The ...

I am also using this program to communicate with a PIC board running Modbus Slave, however I have no answer. Have you done any Slave plate communicating with the PC? I need to send an analog channel t ...

Good afternoon PCM programmer.

I managed to compile.

I deleted all CCS from my PC and reinstalled my old CCS 4114. A routine compiled normally, without problems.

I apologize for not answered ...

Good afternoon again.

I'm not really lucky in this beginning of project. I uninstalled all the CCS, reinstalled again, I got to completely erase the directory PICC. I copied the routine exactly as ...

Good afternoon PCM programmer.

I did exactly as in the example and it still fails, error also occurs. Compiled to use the PIC16F877. I did not put anything out of order and still does not compile. ...

Good morning.

I'm trying to implement a Modbus / RS485 routine to control an inverter LS. However I am having several problems with the drive modbus.c that comes with CCS v5.011. I would simply cal ...

Estou tentando utilizar um PIC16F1938 para fazer comunicação RS485 por modbus com inversores. Comecei utilizando o exemplo da CCS, porem não compila a rotina. Vc tem alguma dia para ajudar?

Desd ...

The getenv version should supply the F000 address. Remember the difference between words and bytes (what is 1E000/2?)....
Realistically the getenv route is the best, since you can just move between p ...

Good morning.

I've found an easier method of finding the data processor.

I was on "VIEW" -> "Special Registers = Device Table Editor" -> "MCU Parts" -> &qu ...

Good morning everyone.

I'm upgrading PIC16F876A to the PIC16F1938 to use the internal oscillator.
I have many problems with crystals due to mechanical vibration.

I am having trouble migrating ...

Good Afternoon for all.

I like to read 4 AD channels simultaneous using DMA in DSPIC33FJ256GP506? I can not do read the four at once at all. I read one after another after another! I used the exa ...
