Hi, I'd really like to give this a try on my nRF52 DK. How hard would it be to make this work with SDK 11.0? I did give it a try but I'm rather new to the Nordic toolchain. Have you tried making this work with the new SDK?

Also since I'm on a mac, using arm-gcc (not Keil). Any chance you might have a arm-gcc makefile?

project will not compile without "ds3234_rtc.h"

Hello, I don't know why but this project is not working on my compiler. It says my ssd1306.c and spi_module.c has problem.
ble_app_uart1.zip

In ssd1306.c, it says nrf_drv_twi.h is not found and on adding it, it says TWIM has problems.
In spi_module.c, it says there is a problem in nrf_drv_spi.h in which there is a file named nrf_spim.h where it says NRF_SPIM_Type is undefined.

I am attaching the zip file of my project, please help me get away with the errors. Thank You in advance.
