#55653 Using the TLC5940 on .NETMF 4.2

Posted by NooM on 26 January 2014 - 08:00 AM in Netduino Plus 2 (and Netduino Plus 1)

well, the tlc5940 is a bit a pain with netmf. it needs timing, wich would be nice in native with a timer (thats what i do on arduino)

- its just a mix of a shift register and a counter

theres different tlc59xx versions wich dont need a gs clock and a blank signal. they work great for led stuff, but not for led matrixes (flickering cos you cant control the blank line - timing issues)

btw: in the second links theres a link to nevyn's blog, with some code. that should work "ok" (i still see a timing issue with an external counter like that - you normally sent the new data directly after you blanked the chip)
