This means that the TLC5940 needs to be connected to certain pins on the Arduino boards. The next step for making an “ATmega_xxU4.h” file is to look at how the TLC5940 works, for those who do not want read the blog post know that the TLC5940 uses the SPI interface. Both links provided give the same diagram confirming the wiring for an Arduino UNO. The next step was to look at other projects using the TLC5940 and compare the wiring and differences. The first step in assuring an “ATmega_xxU4.h” file was to look a the wiring diagram for an Arduino UNO which is available at the same website where the TLC5940 library is located. In order to compensate for this, the group devised a way to create an “ATmega_xxU4.h” file through a combination looking at the “ATmega_8.h” and “Teensy_xxU4.h”. If one were to go into the library of the TLC5940 and into the pinout folders they would find an “ATmega_xxU4.h” absent. The primary issue with the TLC5940 is the lack of support for the Arduino ATmega32U4 microprocessors. By using this file the timers for an ATmega32U4 were set up accordingly for servo control.

The timer set ups for this file were found from an forum post about the TLC5940 and the Leonardo on page 2, post #22 from user sparkle_muffin. In order to fix this the group created an H file titled “tlc_servos_atmega_32_u.h”. The servo control is not for the ATmega32u4. The issue in the H file is in the timer set ups. The first issue with using the Arduino Micro or any ATmega32U4 processor for servo control exists in the tlc_servos.h.
