[En-Nut-Discussion] RTC/Eeprom at the SAM7X EK board

[Lokker, Ronald]

I will add a RTC component to the sam7x dev board

I use the same component as the ethernut3d board X1226

I know that the pinning are different

 

Ethernut3

X1226 SCL (pin6) -> AT91R40008 PIO 17

X1226 SDA (pin5) -> AT91R40008 PIO 16

 

(My) SAM7X

(soft TWI)

X1226 SCL (pin6) -> SAM7X PIO A 26

X1226 SDA (pin5) -> SAM7X PIO A 29

 

In the configurator (I load the sam7x device) I can add the Device
Drivers X12xx diriver enable on

But the os build not the twi lib file 

 

How can I config correctly the hardware to solve my problem 

How works the config tool to build the os

 

Ps at the hardware pins TW I can not connect at this moment the rtc
device
