I recently ordered a EVAL-ADXL345Z-DB from your website.
It came on the courier this morning, however when the device is turned on it is not logging any data to the microSD card.
I have the correct batteries, brand new supplying 2.4V to the board (measured on oscilloscope not just meter)
I have tried updating the firmware to the latest on your website (datalogger_100Hz.hex), the download process works smoothly (interesting I dont see any verify step on your application).
I have probed the SPI_CLK pin to the ADXL345 and there is no activity. My understading is that if the firmware was logging at 100Hz there should be a minimum of at least 300Hz on this pin (one sample per axis)
I have handled the board taking proper ESD precautions.
If there is no SD card present I get a red light.
If there is SD card present I get a green light.
I have attached my file that the card is producing. It seems that every time the unit is powered it is creating the same line, the .csv header but no data follows.
I was hoping this would be straight forward. A little dissapointed today.
Can you offer any help or suggestion?
