Kees Bakker	2a4655b6f8	cpu/samd21: rewrite i2c_init_master to make use of gpio_init_sercom ... The former i2c_init_master was too complicated. It was trying to set IN/OUT mode of the pins, but all that is needed is to set the proper MUX. Also the configuration for the boards was incomplete (no MUX, no pad setting). It was tested on a SODAQ Autonomo, but not on a samr21-xpro	2016-09-21 20:34:22 +02:00
Kees Bakker	be1113fa6c	cpu/sam21_common: move i2c.c from samd21 to sam21_common ... Notice that saml21 does not use I2C (yet).	2016-09-21 20:34:22 +02:00
