Hi guys,
Been a while since i was last on here. I have a general enquiry which im hoping some of you Picaxe genius can please help me with. I am looking to use a picaxe to drive between a 250mw and 5w laser using the onboard pwm. I guess for the bigger laser's I will need some additional circuitry to handle the current requirements. I would also like the same picaxe to read a rotary encoder and based on the output of this vary the laser power with the PWM.
My question before i purchase and begin development is;
Is this achievable with a PIcaxe and if so will there be any limitations using this system over an alternative? or put another way am i going to limit the performance of the system by using a Picaxe (i.e if I need high resolution from the encoder 16bit and its travelling at high rpm etc) is the PWM switching going to be fast enough to get max power from my laser etc?
I would really appreciate your thoughts on this!
Thanks
Anthony
