Misbehaving of ports.

[Nitesh Dubey]

I wrote a program to toggle the pins of P0 and P1.

When I write:

P0=0xff;

P1=0x00; 

Only P0.0 - P0.3 are high and P0.4 - P0.7 and P1.0 - P1.6 are low.

P0=0x00;

P1=0xff;

Only P0.4 - P0.7 are high and P0.0 - P0.3 and P1.0 - P1.6 are low.

Please point at my mistakes.

I have read a query on devzon that this is du to setting debug bit high in the keil IDE. After clearing the bit problem is same.

For new development I strongly recommend to check out the nRF52-series, e.g. nRF52810.

But, what could be the problem in your case: What nRF24 variant is this? Can you read out the content of the infopage? Do you have more than 1 nRF24 to test? Have in mind that some pins will be used by the programming interface also.

Best regards,
Kenneth

I a using NRF24LE1 32pin package. I have already gone through the datasheet set the P1CON registers properly. I have 3 NRF24 to test. I have programmed them individually. But the problem is same.
