Again, I'm not a verilog guy, but I AM a VHDL guy and a hardware guy, and in neither of those domains are you allowed to tie multiple outputs together. Maybe Verilog lets you do this (yet another reason to prefer VHDL), but it's just wrong.
Just think: One output is high and the other output is...
This is quite a confusing post. Your graphs make no sense.
1. What is “vtime”?
2. Where’s your input signal?
3. “ for U10, it charges C8 quickly when the circuit powers up, meaning all capacitors are usually discharged before power up.” This does not make sense.
4. If the output of the NOR...
1) This is nothing like an 0805 resistor. I have no idea what the rest of that question is.
2) You can’t download something that, apparently, doesn’t exist; you’ll have to create your own footprint. They give you the information you need to create the footprint.
Well, i’m confused. How did you make the jump from ‘the display doesn’t show the state of the dip switches’ to ‘the SPI doesn’t work’?
Maybe it’s:
1. The MCP23S08.
2. A bad connection
3. Your code (sorry, i’m not going to read through all that)
4. Your display
Have you verified you can write...
It’s not terribly clear in the data sheet, but it’s a bootstrap capacitor. i think you need to refer to the other documents referenced in the data sheet for further information.
1) Is your input TRULY floating, as it is in your simulation?
2) It's impossible to see what the scale is on your scope. There's way too much garbage on the screen.
3) You say the gain is off, but don't give any information. Is it off by a factor of 10000000000000?
4) Same for "Changing the...
Depends.
Is the RF trace carrying 400 amps? 20000000 Volts? Or, is the RF trace extremely low level where crosstalk from the UART trace could cause a problem?
It's up to you to figure this out. There's no way anybody else can answer this.
This just gets more and more foolish. You're using an N-channel MOSFET to discharge a cap. The intrinsic diode of the MOSFET is the only thing that's going to discharge the cap. Otherwise, the MOSFET is doing nothing.
