Getting Started With nRF9E5

[Anuj Mattoo]

Hi,

I have relay board which is attached to the SoC module nRF9E5 and also microchip serial SPI EEPROM 25AA320 is also attached.

I have the EEPROM programmer and I am able to read, write, delete the EEPROM using programmer.

But I have to test relays and Leds attached to nRF9E5.

How do I get started? How to program the EEPROM for testing relays. Please help!

Hi,

You may want to have a look at the answer here.

Note that, according to section 21.2 in the product specification you need to have 3 configuration bytes in the start address of the EEPROM. You can use eeprep tool to add these bytes.

I wrote just short simple program which Output a pin high in keil and created Hex file. Here is the program :-

  <#include <Nordic\reg9e5.h>

   int main(void)
  {
       P0_ALT = 0x00;     
       P0_DIR = 0x00;  

   P03 = 1;
 
	return 0;
   }>

Then I used eeprep tool and set above given options and created a EEPROM file with 3 bytes in header and then I used Hex2Bin to create Bin file and uplaoded that in 25AA320 EEPROM IC. But the Led doesn't glow. What's wrong? Please help
