4.3.3  Serial Communication

The following sample programs are found in the 

RS232

 subdirectory in 

SAMPLES\LP3500

.

•

SIMPLE3WIRE.C

—This program demonstrates basic initialization for a simple RS-232 

3-wire loopback displayed in the 

STDIO

 window.

The following sample programs are found in the 

RS485

 subdirectory in 

SAMPLES\LP3500

.

•

SIMPLE485MASTER.C

—This program demonstrates a simple RS-485 transmission of 

lower case letters to a slave LP3500. The slave will send back converted upper case let-

ters back to the master LP3500 and display them in the 

STDIO

 window. Use 

SIMPLE485SLAVE.C

 to program the slave LP3500.

•

SIMPLE485SLAVE.C

—This program demonstrates a simple RS-485 transmission of 

lower case letters to a slave LP3500. The slave will send back converted upper case let-

ters back to the master LP3500 and display them in the 

STDIO

 window. Use 

SIMPLE485MASTER.C

 to program the master LP3500.

4.3.4  A/D Converter Inputs

The following sample programs are found in the 

ADC

 subdirectory in 

SAMPLES\LP3500

.

•

AD_RDVOLT_ALL.C

—This program reads and displays the voltage and equivalent values 

of each single-ended A/D converter channel. Coefficients are read from the A/D con-

verter's simulated EEPROM in flash memory to compute the equivalent voltages. Com-

puted raw data and equivalent voltages are displayed in the 

STDIO

 window.

•

AD_RDVOLT_CH.C

—This program reads and displays the voltage and equivalent values 

of one single-ended A/D converter channel. Coefficients are read from the A/D con-

verter's simulated EEPROM in flash memory to compute the equivalent voltages. Com-

puted raw data and equivalent voltages are displayed in the 

STDIO

 window.

•

AD_RDDIFF_CH.C

—This program demonstrates reading one differential A/D converter 

channel. Coefficients are read from the A/D converter's simulated EEPROM in flash 

memory to compute the equivalent voltages. Computed raw data and equivalent volt-

ages are displayed in the 

STDIO

 window.

•

AD_RDMA_CH.C

—This program demonstrates reading one milliampere A/D converter 

channel. Coefficients are read from the A/D converter's simulated EEPROM in flash 

memory to compute the equivalent currents. Computed raw data and equivalent cur-

rents are displayed in the 

STDIO

 window.

•

AD_SAMPLE.C

—This program demonstrates how to use the A/D low-level driver. The 

program will display the average voltage that is present on an A/D converter channel. 

The particular channel and the number of samples may be changed by the user.
