TLD7002-16SYS_EVAL board
User guide
2 Quick start
2.5
Control with Arduino UNO and demo software sketch
The software sketch for Arduino and the TLD7002-16SYS_EVAL can be used as starting point for the software
development with the TLD7002-16ES. This sketch runs an animation to the two TLD7002-16 devices.
1.
Download the TLD7002-16SYS_EVAL sketch from the TLD7002-16SYS_EVAL website
2.
Download and open the Arduino IDE
3.
Connect the Arduino Uno board to the PC with a USB cable
4.
Upload the TLD7002-16SYS_EVAL sketch in the Arduino Uno (D0 pin must be disconnected)
5.
Close JVS_VL in order to use a single power supply
6.
Connect the TLD7002-16SYS_EVAL to the Arduino Uno with jumper wires as shown in the figure below
a.
GPIN0a and GPIN0b connections are optional, use them if OTP emulation is needed
7.
Connect the GND at the (-) terminal of a 6 V to 20 V 1 A power supply
8.
Connect VS_REV to the + terminal of the power supply
9.
The TLD7002-16SYS_EVAL (address 2 only part) will show a wiping indicator
10.
Optional: open Tools > Serial Monitor and set the speed to 230400 bps to see diagnostic prints
Note:
It is not possible to upload a sketch to the Arduino Uno if the RX commander Jumper wire is
connected to the Arduino. Therefore, when a new sketch is uploaded, the RX commander wire must be
momentarily disconnected from the Arduino D0 pin.

OTP configuration
The TLD7002-16SYS_EVAL comes with pre-written OTP memory on the two TLD7002-16ES devices. In case
a different OTP configuration is required, (e.g. GPINx set as analog inputs, increased LED current), it is
possible to emulate a new OTP configuration in the TLD7002-16ES directly from the Arduino code by using
the OTPemuComplete() function.
The OTP configuration files, pre-written in the TLD7002-16SYS_EVAL LED drivers, are provided on the
TLD7002-16_ES website [4]. The OTP wizard can be used to read the OTP configuration files. The OTP wizard
tool (see
Figure
7) can used to read and interpret the .ocfg configuration files. The tool can be installed from the
Infineon developer center [5].
