Measure EZ-BLE Creator Module Current Consumption
To measure the EZ-BLE Creator Module current, follow these steps:
1. Remove the zero-ohm resistor R28 and install a 2-pin jumper in the supplied holes of J3.
2. Connect an ammeter across the 2-pin jumper to measure the current to the EZ-BLE Creator
Module.
This method can be used either with USB power or with the power supplied to one of the VTARG
pins (J5.1 or J4.1), but NOT when supplying power to one of the P6.VDD pins (J1.1 or J1.20).
After measuring the current consumption, populate resistor R28 or place a shorting jumper across
the two jumper pins for normal operation of the kit.
Note:
After removing R28, system may have some leakage power such as the following:
1. Communication circuitry between KitProg2 and Target (I2C, UART, SWDIO)
2. Reset switch between KitProg2 and target device along with PSoC 6 MCU
A.2.4
Board Separation (Snapping)
The PSoC 6 BLE Prototyping Board consists of a PSoC 6 MCU and a KitProg2 board. To separate
the two boards for evaluation or development, break the two boards apart at the built-in perforated
edge between
J4
and
J5
.
The easiest method of separating the two boards is to place the kit on the edge of a table, where the
edge of the table is directly below the perforated edge and the smaller KitProg2 board is off the table
edge. Press gently on the KitProg2 board and snap the two boards apart. If any material is removed
from the edge of the boards, use sheers to clean up the edge of the kit.
Figure A-6. PSoC 6 BLE Prototyping Board broken into two parts
After the PSoC 6 BLE Prototyping Board is broken into two, the two halves can be reconnected for
programming and debugging by adding connectors at J5 and J6. Also, a Cypress MiniProg3 device
can be connected to a connector at J5 to perform programming and debug.
Caution:
Once the boards are separated, direct UART and I2C
connections between the EZ-BLE Creator Module and KitProg2 are lost.
This is because the traces connecting the UART and I2C lines are cut off
during the separation. However, you can access KitProg2’s UART and I2C
lines through header J6 and make the following connections to J2.
UART Reconnect:
■
J6.7 to J2.16 (PSoC 5LP P12.6 to PSoC 6 P5.0)
■
J6.6 to J2.17 (PSoC 5LP P12.7 to PSoC 6 P5.1)
I2C Reconnect:
■
J6.5 to J2.19 (PSoC 5LP P12.1 to PSoC 6 P6.5)
■
J6.4 to J2.18 (PSoC 5LP P12.0 to PSoC 6 P6.4)
