How to configure and connect? No signal on SDA and SCL. Look SaleaLogic. Built example and flashed. But there's nothing.
It actually should work with STM32F103 ?
I tried different options on the Sda and Scl lines or what not. Board Maple Mini + Tiny RTC

It is supposed to work.

Make sure to configure the pins correctly and look at this article: http://wiki.chibios.org/dokuwiki/doku.p ... e_shooting

Thanks.
Why in you test / example don't use - like that ?
palSetPadMode(GPIOB, 6, PAL_MODE_STM32_ALTERNATE_OPENDRAIN); /* SCL */
palSetPadMode(GPIOB, 7, PAL_MODE_STM32_ALTERNATE_OPENDRAIN); /* SDA */

it help for me.

Some pins are programmed in board files (board.h).
