I believe i need a translator arduino to interface between the components. I know im in over my head but i need to do something to get my project at least moving. Im building a router, printer, laser engraver all the components and structure is done i just can get the damn electronics talking.
I have nothing but BLDC motors which i thought was great since they will be more accurate etc. The challenge is getting them to talk. I found in github a SME that designed a dc closed loop control for arduino mini to interface with a AB encoder 400 lines and then convert the step signals to PID for the driver.
Ive tried DAC even adding OPAMP but the signal from the steps is still not visible. I got the oscilloscope and the duty cycle is only 2% always the only thing that changes is the pulse width to accommodate what seems like acceleration. Total lost right now and i cannot find any low priced drivers that accept PWM. Frustrating since im going to school and my budget is sunken wreck.
What makes it worse is i dont know much about programming arduino. Tuning on leds and stuff like that doesnt help translate commutation, ttl, or anything else. Id like to have something so i can start manufacturing circuits to practice what im reading and learning.
