will I have some problems in the future due to the slow level shifting?
everyone seems to agree that the best logic level shifter for WS2812B is the Texas Instruments 74HCT245 and similar.
this configuration seems to work perfectly, I'm using it since many days as a PC Ambilight and I am not experiencing visible problems but...... should I upgrade my logic level shifter from the sparkfun to the Texas Instruments?I'm asking it because I don't want to solder a new circuit, now it works and I would like to leave it as it is.Will I have some cons in using this circuit with that logic level converter for a long time?
Can you explain me why the Texas Instruments it's better?
My experience so far has been that ws2812 LEDs can be driven directly by a 3.3V Arduino such as WeMOS mini. I may well just have been lucky so far.
My theory as to why the LLC modules are unstable is that they don't switch fast enough. i2c signals switch at 100KHz, although they can also optionally be 400MHz on most Arduino. ws2811 signals switch at 400KHz and ws2812 at 800KHz.
will the 74HC14 fit on a breadboard
400MHz? I seriously doubt that.
YesWire it like this:-
I'm not able to read that schema.
I'm not able to read that schema. Is there a more simple one that says where to connect pins in an Easter and less technical way?Something like the one I posted on the first post
