Hello,
I'm using a single TLC5926 to drive 16 LED strings. I have coded the error detection function. Surprisingly, the first time I call the error detection function, the MISO signal only returns '0' even whatever the string status is. But I'm not in overtemperature condition... I have to perform the test a second time to get a valid result. Any new test performed later is valid. But after power down and re-power up, the first test is always invalid.
After power up, I wait for 15ms before communicating. Even if I increase this delay to several second, that do not solve the problem. Whenever I perform the test before trying to start LEDs driving or after having used the driver to drive LEDs, the problem is still here, ths first detection is invalid...
I checked all the chronograms and they are exactly like in the datasheet.
