i. Enter WR 00 02 and press [Enter]. This action writes a value of 2 to register offset 0. The
ii. Enter WR 00 00 press [Enter]. This action writes a value of 0 to register offset 0. The LED
iii. Enter WR 00 01 press [Enter]. This action writes a value of 1 to register offset 0. The LED
i. Enter WR 02 and press [Enter]. This action sets the register offset pointer to point to the
ii. Enter RD 02 and press [Enter]. This action reads two bytes from the PSoC. The current
i. Enter WR 00 and press [Enter]. This action sets the register offset pointer to 0.
ii. Enter CRD 04 and press [Enter]. This action initiates a continuous reading of four bytes
iii. Adjust the potentiometer in the top right quadrant. The Volt values in the HyperTerminal
iv. Press [Enter] to terminate the data stream from the PSoC.
The WR command’s register address parameter sets the read/write offset pointer. All byte
values following the register address parameter in a WR command are written starting at
the location specified by the register address parameter. Subsequent RD or CRD com-
mands will start reading from the last register offset pointer location set by a WR com-
mand.
The register address value used in the WR command is dependent on the Interface Reg-
ister Map of your project. This information is provided in Table 2 of the DataSheet project
report.
