Hello, I am using nrf51 and sdk11. I am trying to add twi drivers to code. I have added and also added path for the twi drivers. But I am getting error as "............\components\drivers_nrf\twi_master\nrf_drv_twi.c(38): error: #35: #error directive: "Wrong configuration." Can anyone help me to solve this? I have successfully added twi drivers to sdk12 project by adding few lines in sdk.config files but in sdk11 I cant find sdk.cofig files. So how can I add drivers in sdk11? Thanks, Shailav
