Can Midibox drive TLC5947 (24ch PWM, 12 Bit SPI)

[jrp]

Dear Forum, like the titel suggests. The TLC5947 can be bought in ready soldered modules and was suggested to me for dynamically driving solenoids, as an alternative to dac channels i proposed in my other thread.

Reason is the parts count, so before i build 24 ladders with analog shaping and drivers i thought i should maybe look into pwm once more.

So the question is if from within an mios32 application, i can use the SPI interface. If so i would try to code some form of "hello world" example with the pwm module first and then go from there.

Also is it fast enough? I need a pulse of less than 5ms to minimize the on time of the solenoids and give good response with pecussive instruments.

 

Has anyone done something similar?

Thanks!
