Description

Template application over nrf51 SDK using Eclipse IDE. Just write your code in template_application.cpp

Prerequisities

nRF51 SDK

• Provided when purchasing nRF51 development kit
• An alternative consist in using Nordic nRF51 mbed source files http://developer.mbed.org/platforms/Nordic-nRF51822/

Modifications

• in path_to_nrf51_sdk/nrf51822/Source/app_common/app_common.c

//TO add at beginning
volatile uint64_t rtc1_overflow_count=0;

//replace method body
/**@brief Function for handling the RTC1 interrupt.
*
* @details Checks for timeouts, and executes timeout handlers for expired timers.
*/
void RTC1_IRQHandler(void)
{
   if( NRF_RTC1->EVENTS_OVRFLW != 0)
   {
   	rtc1_overflow_count += 0x1000000LLU;
   	rtc1_overflow_count &= 0xffffffffffLLU;
   	NRF_RTC1->EVENTS_OVRFLW = 0;
   }
   if( NRF_RTC1->EVENTS_COMPARE[0] !=0 )
   {
   	// Clear all events (also unexpected ones)
   	NRF_RTC1->EVENTS_COMPARE[0] = 0;
   	NRF_RTC1->EVENTS_COMPARE[1] = 0;
   	NRF_RTC1->EVENTS_COMPARE[2] = 0;
   	NRF_RTC1->EVENTS_COMPARE[3] = 0;
   	NRF_RTC1->EVENTS_TICK       = 0;
   	// Check for expired timers
   	timer_timeouts_check();
   }
}

JLink GDB debugger

• GDB server can be found here https://www.segger.com/jlink-software.html
• GOT some disconnections on linux

STLink - openocd

• details here : https://github.com/RIOT-OS/RIOT/wiki/Board:-yunjia-nrf51822
• for code uploading refer ./scripts/openocd/open_ocd_upload_application.sh - http://openocd.org/doc/html/Flash-Programming.html
• to debug : http://openocd.org/doc/html/GDB-and-OpenOCD.html
  • in eclipse : http://gnuarmeclipse.github.io/debug/openocd/#create-the-debugger-configuration

Eclipse

Eclipse CDT with GNU ARM plugin http://sourceforge.net/projects/gnuarmeclipse/

• in "Project Properties" -> "Resource" -> "Linked resources" : NRF51_SDK_PATH pointing to nrf51822 folder of Nordic nR51 SDK
• in "Project Properties" -> "C/C++ build" -> "environment" :
  • NRF51_SDK_PATH pointing to nrf51822 folder of Nordic nR51 SDK
  • JLINK_DEBUGGER_PATH pointing to JLinkGDBServer folder

Others

• Softdevice must be flashed on target (for details refer https://github.com/mrquincle/bluenet )
• modify ./CMakeBuild.config according to your setup

cd scripts
./softdevice.sh upload

Application configuration

• Event queue
