TLC6C5724-Q1: How to drive TLC6C5724-Q1 EVM ?

Other Parts Discussed in Thread: USB2ANY

Hello TI,

I made MCU send SPI signal to drive TLC6C5724 EVM, but the EVM could not be lit and the SDO port had signal transfer. The following is the signal I captured. Please help me check what was wrong.

(PS: The signal data that I sent to the register(GS or FC_BC_DC) was copied from the TLC6C5724 EVM GUI which can successfully light the EVM.)

Hi Fei,

First, did you use external 5V/3.3V to power up the device if not using the USB2ANY box? Normally as long as you configure the part to AUTO-REPEAT mode, pull high the BLANK pin, setting the valid BC/DC/GS data, the part should work normally.

Yes, the root cause is that I did not power up the evm VCC with extra 5V/3.3V. I thought that only using the 5V USB cable as evm power supply would be fine. Now the evm works fine. Thank you for your support.
