Thank you, I changed the drawing.the pins numbering on that connector doesnt match the IC, so check that.
Thank you Dana,What would make UP hot could be several things -
1) Current injection into/out of a pin by taking pin outside its
supply rails by ~ a Vbe or more, below ground or above Vdd.
2) Excess loads on output pins.
3) Clocking rate out of spec high.
4) Excess supply V on Vdd pin.
Regards, Dana.
Sounds like a code problem with the write routine.Do you have idea why my MCP4261 need manually power off time by time, otherwise it can't be write correctly.
Actually, the code from: http://matthewcmcmillan.blogspot.com/2014/03/arduino-using-digital-potentiometers.htmlSounds like a code problem with the write routine.
Regards, Dana.
Yes, I attached the new drawing, for shown the whole view, what not in the view are: USB from MEGA, +5V and GND to MEGA.Look at post #9 and read it again. Show how exactly you have everything connected, all components and all connections.
