Key Document


The objective of the TIDA-00980 reference design is to develop an embedded firmware to interface and control the functions of a multi-segment RGB signal tower used in factory floor and industrial process automation of greater complexity. This design helps to give more flexible usage along with a sequence of terminal commands. The stack light can be controlled either via IO-Link or USB and different patterns can be configured.

  • Flexible and easy-to-control RGB LED tower light design
  • Different switchable modes: demo, temperature, humidity and IO-link
  • Controllable RGB color, brightness, row and blinking speed
  • One to five RGB LED segments with four individual channels each
  • Adjustable maximum LED current up to 60 mA per channel
