Code Examples
Note
The measured value might have an error of upto 10 counts due to ADC offset or potentiom-
eter inaccuracy.
Figure 5-31. LCD Displaying ADC Value
4. Vary the potentiometer and observe the change in the value of LCD.
Note
ADC values may fluctuate several counts due to system noise or if the potentiometer volt-
age is at the edge of an ADC count.
5. Save and close the project.
5.1.4
Verifying Output using UART
The PSoC project in
“Creating My First PSoC 1 Project” on page 31
uses an UART module in the
design. The ADC value that is displayed on the LCD can be viewed on a terminal application such as
HyperTerminal or TeraTerm on a PC. To view this output, apart from the hardware connections in
“Verifying Output using LCD” on page 46
, a RS-232 cable needs to be connected from the CY3210-
PSoCEVAL1 board to a COM port on a PC, as shown in
.
