Hi guys,
I got experienced with SNES hardware and creating micro-controller circuits around them. I have questions regarding Current.
So God only knows that my current setup is "healthy" for my MCU.
I want to learn more about everything electronically here.
I don't know where to begin, I landed somewhere in the middle of digital electronics. I feel lucky to have my SNES Flasher working. Because I have no idea how the 'current' aspect is working.
I'm guessing from a glance at my chip's datasheet (ATmega8515) the i/o lines only send out a small amount of mA. Why mA? I guess that makes SNES cartridge happy enough, although I don't know why. (Why SNES Cartridge happy with some mA)? Is it cause those lines only use Voltage for logic?
I haven't checked that the Input Power to my circuit (USB) has a certain current either? So far I don't even know what it's pumping out. For my specific app, I am using FTDI and I'm pretty sure FT_PROG sets the current output to some hundred mA. However, I am venturing away from FTDI to native USB, so I need to know the correct steps to calculate with current for my new designs. How do I watch over it, make sure adding new parts to my circuits doesn't break anything regarding current? Does connecting components in parallel not affect current? Series? I can answer some of these questions on my own. Please acknowledge the broader .
How does one know what the current should be on the circuit as a whole, how it should be on i/o lines etc.
I am also asking this question in light of that fact that I am planning on throwing a 8x flip flop on 8 digital i/o lines. I dont know the correct output current the chip should have. Most output some form of some mA and I suppose once again, that everything is based on voltage and as long as the current is some small mA that it won't hurt/help anything. Am I right? I am connecting in parallel, intuition tells me that won't be a negative addition to the circuit. My level of electronics knowledge needs to get UP'd here.
Any help is so totally welcome.
Thanks in advance,
Bazzinator
