Example Projects
5.2.3 Verify Output
To verify the CAN_Simplex_Tx_CY8CKIT-044 example project, perform these steps:
1. Program the CY8CKIT-044 PSoC 4 M-Series Pioneer Kit with CAN_Simplex_Tx_CY8CKIT-044
code example through USB connector J6.
2. Ensure that the power supply and jumper settings are proper, as explained in the Hardware
Connections on page 38 .
3. Perform these steps if you are using any CAN analyzer for receiving the data:
a. Install the appropriate software of the CAN analyzer.
b. Open the CAN analyzer software and set the Baud rate to 125 Kbps.
c. Touch the CapSense gesture pad buttons (Center/Right/Left/Up/Down) and observe the data
on CAN analyzer software, as provided in Table 5-2 .
d. The Sys Tec CAN analyzer is used as an example for this project. Data can be observed, as
shown in Figure 5-2 .

1. Pressing these buttons transmits the CAN data only when the Byte1 is ‘1’ (i.e., center button is ON). If Byte1 is '0' (i.e., center button is
OFF), pressing these buttons does not have any effect.
