Hi i'm a beginner in MCUs world . i'm facing some issues ... in LPC17XX datasheet there are 6-output general purpose PWM available in LPC1768 I'm planning to use 7 PWM pin to control the speed of 7 BLDCs by ESCs but i need one more PWM pin .(i need them separately)
sometimes it happen that some more pin of a kind are required separately(i mean asynchronous) do you have any idea how to solve this problem ? by the way this micro has one specialized motor control PWM can i use it for 7th one ? i may also need some more PWM pins for 2 or 3 DC motors (synchronous) .
I've found out that one expanding way is using multiplexers for synchronous buses . one more way that i saw pple used with arduino was Latch method and shift register method ( in this method they use 74Hc595 ).... but they have their own difficulty ....
Having other people doing the studying is not learning...
Sometimes solving the problem is about picking the right part, not hogtying yourself to decisions that complicate later ones..
