TLC5940RHBR Frequently Asked Questions (FAQs)

  • The maximum frequency of the clock input is 50 MHz. However, it's recommended to use a clock frequency between 10 kHz to 20 MHz for optimal performance.
  • To ensure proper initialization, apply a reset pulse to the RST pin, then send a 'mode set' command (0x01) to the device. This sets the device to its default state.
  • The GSCLK pin is the grayscale clock input. It is used to update the grayscale data in the device. The frequency of the GSCLK determines the grayscale update rate.
  • The brightness of the LEDs can be adjusted by modifying the grayscale data sent to the device. The grayscale data is an 8-bit value that determines the brightness of each LED, with 0 being the darkest and 255 being the brightest.
  • The TLC5940RHBR can drive up to 16 LEDs. However, it's recommended to use external transistors or FETs to drive high-current LEDs.
