CC2510: CC2510 SPI Communication

Part Number: CC2510

Hello,

I am using LIS2DE12 motion sensor with CC2510 over SPI communication. The logic is "on motion detection, enable TX/RX of CC2510". The module worked well for 3 to 4 days but post that it stopped communication with the sensor. On power OFF & back ON, it started working.

What can be the issue?

For one of the sample module even ON/OFF also didn't work. I had to reprogram the chip.

Please help

    Hello Venu,

    Based on your synopsis it would appear that there is a memory leak or corruption.  Which code examples are you basing your project development on?  I would recommend making incremental changes to determine which portion causes the issue described.  You should also consider methods which could accelerate the issue for easier replication.  Can you use an IAR debugger session to further determine the cause of the device failure?

    Regards,
