Sorry for the lengthy post.
Our application requires us to capture a 5 MP image every 10 minutes or so, and transfer it over Wifi to a local server. We are battery operated so power consumption is a key careabout.
Image Capture:
-
What is the approximate time to wake up from standby to full image capture?
-
Do you have reference firmware (drivers) to control an external camera module (eg: TDnext Omnivision 5MP camera module)
-
Does an external camera module directly connect to the CC3300 or need a special connector/cable to interface?
-
Can we get or purchase
-
An EVK with the CC3300 and an external camera module such as the one above, or
-
A CC330 reference board which you would recommend as being compatible with the camera module referenced above?
Wifi:
-
Can you provide some reference code for transmitting a 1.5 MB compressed file from external memory (say an SD card) over Wifi? We would like this to use a DMA transfer.
-
Would you recommend SD card or a flash memory for file storage. We want to store image(s) in the memory. Would you recommend flash or SD card?
-
Can you confirm the power numbers based on your datasheet? Based on the numbers below, which TX power should we use. We don't want to be too conservative or too optimistic.
TX power level = 0 54 OFDM, typ power = 226 mA
TX power level = 4 54 OFDM, typ power = 163 mA
TX power level = 0, 6 OFDM, typ power = 254 mA
TX power level = 4, 6 OFDM, typ power = 185 mA
Is there a power control loop in software? If so, can we get that as a reference design?
-
Please confirm that while the Wifi is sleep, the power consumption of the MCU is 15 mA
-
What is the typical wake-up routine after WiFi sleep? How long does it take?
Example:
- restablish connection,
check wifi status
Transmit
Do you recommend someone who provides design services to put this CC3300 + camera module and battery together?
