NRF24LE1 qfn24 deep sleep current too high

How to enable/disable debug mode is described in figure 16 on page 15 of the Keil C51 Appnote.

If you are new to development for the nRF24LE1 you might want to read through the whole appnote, it has a lot of helpful information.

Best regards

Make sure you don't flash the chip with debug mode. If you just leave your code with

while(1){ PWRDWN = 0x01;} what current do you have ?

i have the sample problem with power consumption 600 - 700 uA

do you have any idea ?

#include <reg24le1.h>

#include <stdint.h>

#include <stdbool.h>

#include "hal_delay.h"

#define LED P13 // LED output

#define RSW P14 . // Button wake up

void main()

{

P1DIR = 0x10;

LED = 0;

OPMCON = 0x00;

OPMCON = 0x00; // Open latch

while(1)

{

if(PWRDWN & 0x80) { PWRDWN = 0; }

WUOPC1 = 0x10; // Wake up on Pin P14

if(P14 == 1)

{

LED = 1;

delay_ms(200);

LED = 0;

OPMCON = 0x06;

PWRDWN = 0x01;

}

else

{

LED = 1; delay_ms(200); LED = 0;

OPMCON = 0x02;

PWRDWN = 0x01;

}

Hi Subver,

Could you post the code you used for testing ? Erasing Infopage is not something we recommend as it contains calibration data stored in production and varied between chips.
