SPI example: Application doesn't toggle LED

[Christoph_I]

Hey guys,

I'm working with the Laird DVK-BL652 and the Nordic SDK v.14.2.0 with Eclipse (Kepler) and try the example "SPI Master". I didn't modify this example but after compiling and flashing the application doesn't toggle LED... I think the application doesn't execute SPI transactions.? Can someone help please?

Thanks in advance,

Christoph

Are pins mapped to the correct IO ? The examples are made for the Nordic DevKit.  IO pins map might be different.  

Eclipse Kepler is quite old too.  Follow this blog to get you updated with latest Eclipse and SDK 16.

Hey Mojo,

thanks for your answer. You are right. I don't think the LED on the Nordic DevKit needs to be configured or something in this way. Now I have manually integrated a LED from the board into the program and it works. My LED blinks after each transaction.

Eclipse Kepler: I bought this board (DVK-BL652-SA https://www.lairdconnect.com/wireless-modules/bluetooth-modules/bluetooth-5-modules/bl652-series-bluetooth-v5-nfc) and on the manufacturers side is only this instruction (https://www.mouser.de/datasheet/2/986/BL652_Dev_Kit_User_Guide-1591025.pdf) which recommends Eclipse Kepler and Nordic SDK v.14.0.0. What do you think about it?

SPI example:

Do you know which register is adressed in the last line? I can't find it in LIS3DH-Datasheet (accelerometer).

//MOD BLOCK FOR NEW REG

static uint8_t       m_config_buf1[] = {0x20,0x97};   //CTRL_REG1: 9 = normal power mode (1.344kHz), Low-power Mode (5.376kHz); 7 = Z-,Y-,X-axis enable
static uint8_t       m_config_buf2[] = {0x23,0x88};   //CTRL_REG4: 8 = output registers not updated until MSB and LSB reading; 8 = high-resolution output mode enabled
static uint8_t       m_config_buf3[] = {0x22,0x10};   //CTRL_REG3: 1 = ZYXDA interrupt on INT1 enable
static uint8_t       m_config_buf4[] = {0x1F,0x80};   //TEMP_CFG_REG: 8 = ADC enabled
static uint8_t       m_config_buf5[] = {0x23,0x88};   //CTRL_REG4: 8 = output registers not updated until MSB and LSB reading; 8 = high-resolution output mode enabled
static uint8_t       m_config_buf6[] = {0xA3,0x00};  //???

Hi, 

The latest question is far away from the subject. Please create a new support case.
