Hi guys, thanks for your answers,
According to
this project (see "Assembly and testing" section - Step two) and
this thread (first answer, by "jamodio"), the ENC28J60 can be tested before being connected to any microcontroller. Apparently, when you connect an ethernet cable, and if the ENC28J60 is properly connected, one of the leds driven by the ENC should come lit indicating that there is an active ethernet link...
I tested the floowing cases but nothing seems to happens:
- /CS pin directly to GND
- /CS pin with 10k 3V3 pullup and connected to GND
- /CS pin with 10k 3V3 pullup and connected to 3V3
- /CS pin just with 10k 3V3 pullup
- /CS pin just with 10k pulldown
- /CS floating
the osc pins are delivering 1.7 volts...
But i noticed something on my Magjack and i want to know what you guys think of it:
pins 1,2,3 are connected to each other by default.
Same thing for (4,5,6), (7,8,9) and (10,11,12)
does this have something to do with the common-mode choke placement?
I'm starting to think that i bought the wrong Magjack. Datasheet can be found **broken link removed**.
