CCS RS232 DEMO DRIVER DOWNLOAD

The use delay directive provides the compiler with the information about the clock frequency at which the PIC is running. You can find the RS module here. PC connection Now, since we have the required hardware and firmware, we can connect the hardware to the PC. The level converter is required to translate the voltage level of the microntroller to RS voltage level. That is a really great feature of the CCS C compiler. The below picture shows the necessary connections. On startup it will ask for a connection name.

Needless to say, the properties have to match the settings we are using in the PIC.

It is more or less self explaining: That is a really great feature of the CCS C re232. Just enter a text which will identify the connection, e.

Once this is done, just reset the PIC and the demo output shal be visible. Only the some parameters have to be provided, the rest is done by the compiler. The use rs directive provides the compiler the information about the RS parameters which shall be used for the communication.

Data sent by the microcontroller will be shown in the terminal window and any key pressed inside the terminal will send the corresponding key code to the microcontroller. You can find the RS module here. I have developed deemo RS module which allows direct connection to the microcontroller. We will use this simple configuration to test and understand the RS communication.

For serial communication the line used to transmit data is called TX and the line used to receive data is called RX. To be able to see the data transmitted from the Microcontroller and to send data to the Microcontroller we have to run a terminal program on the PC.

The use delay directive provides the compiler with the information about the clock frequency at which the Rs23 is running.

It hides all the register settings for the user. These external capacitors are required for the charge pump inside the chip which generates the required voltage levels. You can find it in the Communication Folder: On the PC we will use a termial program to send and receive data. It just requires 4 capacitors to do its job.

In the following dialog we have to set the connection properties. PC connection Now, since ccw have the required hardware and firmware, we can connect the hardware to the PC. On startup it will ask for a connection name. RS is a standard for a serial communication interface which allows to send and receive data via at least three wires.

The connections on the DB9 connector between pins 1,4,6 and 7,8 are required to satisfy the RS hardware handshake signals which we will not use here. They are available at low cost. The below picture shows the necessary connections. The level converter is required to translate the voltage level of the microntroller to RS voltage level.

I will show here how to use HyperTerminal which is included in Microsoft Windows. Hardware Picture Below a picture of the hardware setup.

Block Diagram The following block diagram shows the whole setup: PIC receives data and sends it back. There are a lot of terminal programs available.

Software Now since the hardware is ready we have to write the software for the PIC microcontroller. The RS interface can be used for many purposes like sending commands from a PC to rs2322 microcontroller, send debug information from a micontroller to a terminal, download new firmware to the microcontroller and many other things.

This will be important later when we configure the baudrate for the serial communication.
