• ( I2C address << 1 )
• IIC_WriteReadBuffer( ( I2C_ADDRESS << 1 ), wBuffer, wLength, rBuffer, rLength);

wBuffer[0] --> I2C register address

wBuffer[1] --> data to write

• When reading: wLength = 1
• When writing 1 byte: wLength = 2

project properties window, then to C/C++ build --> settings --> GNU ARM C linker --> Libraries, then in the Libraries (-l) window, click "Add..>" and type "m" in the window that pops up. This should allow you to add the standard C math library into the project.

• No. 1: Clean build !!!
• enable necessary clocks
• include all em_lib.c files
• include all em_lib.h files
• include folders in project
• Sometimes you think it's included, but it's not!

• Debug --> Debug Configurations --> Exceptions --> Enable All

• Project properties --> C/C++ Build --> Settings --> Debug Settings --> Debug Level --> Maximum (-g3) or Default (-g)

• Project properties --> C/C++ Build --> Settings --> Optimization --> None (-O0) or Optimize for debugging (-Og)

• Problem can be invisible character in code:
  With: #ifdef x -- #endif check until where code runs

• Disable pins using: GPIO_PinModeSet(BLE_PORT, BLE_PIN_TX, gpioModeDisabled, 0);

• Do NOT use 1 at the end, this sets a pullup resistor and draws about 15 microA per pin!!

• Disable clocks to all peripherals

• When using RTCDRV timer, you must use RTCDRV_DeInit() otherwise MCU will wake-up every 7-8 minutes.

Correct usage:

RTCDRV_Init();
RTCDRV_AllocateTimer (&IMU_Idle_Timer );
RTCDRV_StartTimer( IMU_Idle_Timer, rtcdrvTimerTypePeriodic, 2000, (RTCDRV_Callback_t)CheckIMUidle, NULL);
RTCDRV_StopTimer( IMU_Idle_Timer );
RTCDRV_DeInit();

• No ground plane under antenna

• Use test-points + jumpers

• Decoupling, decoupling, decoupling!

• 100nF on VDD lines

• ALWAYS follow datasheet recommendations

• Be carefull with ground planes next to traces!, this creates parasitic capacitances which may influence your circuit

• Separate DGND and AGND plane - separate by condensator or high ohm resistor

• git reset --hard d4df9b850f25ae8ae81a41d7979ebbdb77a1eefb

• git push origin +d4df9b850f25ae8ae81a41d7979ebbdb77a1eefb^:develop

• d4df9b850f25ae8ae81a41d7979ebbdb77a1eefb = commit nr

• develop = branch name

• git branch newbranch_name
