Is there a listing of the program that come loaded on the STM32 Nucleo L031 board?

Hi Folks,

I've just started working with the STM32 NucleoL031 board and I think it would help me understand the system if I can find a listing of the program that is pre-loaded on the chip.  It blinks the green LED at one rate and if you put the jumper on that connects GND with D2 it will blink at a slower rate.

I've searched through the ST site but can't seem to find it.

Thanks in advance,

Richard

In CubeL0, under Projects/[board name]/Demonstration

Thanks Jan but the only demo project is the one where you need the Gravitech add-on board to display the power consumed.  I only have the Nucleo32L031 board that blinks the green LED.  The firmware must be a trade secret, why else would they not let us users see it.

That still might be it. Did you try? The binary (hex) is enclosed.

snippets from the source:

  /* Initialize the Gravitech 4 digits 7 segments nano shield */

  if(BSP_DIGIT4_SEG7_Init() != HAL_OK)  {    /* Initialization Error */    Error_Handler();  }[...]void Error_Handler(void){  /* Configure LED3 */  BSP_LED_Init(LED3);  while (1)  {    /* Toggle LED3 with a period of one second */    BSP_LED_Toggle(LED3);    HAL_Delay(1000);  }}

JW,

Thanks.  I was able to wade through the Gravitech code and I was able to blink the green LED at various rates.
