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 ....
