Hardware changes #15

Open VojislavM opened 6 years ago

VojislavM commented 6 years ago

new SFP pins:

SFP 2 RATE SELECT - GPIO10 (have hardware pull up)
SFP 1 RATE SELECT - GPIO11 (have hardware pull up)
SFP 2 TX DISABLE - GPIO8 (have hardware pull down)
SFP 1 TX DISABLE - GPIO9 (have hardware pull down)

RGB signal status led is no longer on the GPIO40 pin

RGB signal status - GPIO12

Power measurement

INA219 - I2C1 (GPIO44, 45)

Isolated FET switch (for lens heater):

lens heater - GPIO17

front panel GPIO, currently not used:

front GPIO - GPIO20

New HUB chip instead LAN9512

new HUB - LAN9514, it has 4 USB ports, and we will use only 2 (USB2 and USB3)
power switches for the USB ports are connected to the HUB PRTCTL pins, see how to turn on and off these pins

Testing changes manually:

Isolated FET switch GPIO17 (0= turned on, 1= turned off)
