5 First time use
Make sure the LPC1769 is flashed with the correct LPC FW (see 3.2).
Make sure that the VCOM driver is installed (see 3.1).
5.1 Jumper settings
The default jumper settings allow a direct use with the USB connector only. This might
show limited performance due to a current limitation on the USB host. So, for real
performance measurements the external power supply should be used.
5.1.1 USB only
The jumper settings as shown in Fig 9 provide the default settings, using only USB for
power supply (no external supply required).
5.1.2 External power supply
For the use of an external power supply the jumper J101 must be changed as shown in
Fig 10.
The external power supply must provide a voltage level of V
ext
= 7.5 … 12V with 500mA.
For some of the analog tests (i.e. measuring ITVDD) it might be useful to only power the
TVDD supply externally. This can be done using the jumper JP300, as shown in Fig 32.
Either the jumper can be replaced with a DC ampere meter to measure the ITVDD, or an
external 5Vdc power supply can be directly connected to the right pin of JP300.
Note: Several GND pins are provided on the board. They all are connected.
