Kit Operation
Figure 3-12. KitProg USB-I2C Connected in Bridge Control Panel
USB-I2C is implemented using the USB and I2C components of PSoC 5LP. The SCL (P12_0) and
SDA (P12_1) lines from the PSoC 5LP are connected to SCL (P3_0) and SDA (P3_1) lines of the
PSoC 4 I2C. The USB-I2C bridge currently supports I2C speed of 50 kHz, 100 kHz, 400 kHz, and
1MHz.
Refer to Using PSoC 5LP as USB-I2C Bridge on page 76 for building a project, which uses USB-I2C
Bridge functionality.
3.5 Updating the Onboard Programmer Firmware
The firmware of the onboard programmer and debugger, PSoC 5LP, can be updated from PSoC
Programmer. When a new firmware is available or when the KitProg firmware is corrupt (see Error in
Firmware/Status Indication in Status LED on page 107), PSoC Programmer displays a warning
indicating that new firmware is available.
Open PSoC Programmer from Start > All Programs > Cypress > PSoC Programmer<version>.
When PSoC Programmer opens, a WARNING! window pops up saying that the programmer is
currently out of date.
