We need to find a platform that support MIPI camera(DVP camera is also ok). And It's powered with 3V supply. We hope the consumption is as low as possible.
Hello Jumping Mark,
The i.MX RT1050 is the lowest power consuming device that will support the MIPI CSI communication protocol. We do have other microcontrollers that are low power, but unfortunately do not support this interface.
There are two application notes describing how to interface the camera with the i.MXRT1050, these are:
Developing a Camera Application with i.MX RT Series
Developing a simple UVC device based on i.MX RT1050
In addition you can find examples in the SDK that you can download from the MCUXpresso SDK website.
Thanks for your help, I just had a quick look of RT1050. And I still get some questions. We don't usually keep it standby, most of time we just shut it down only when the device detects someone and it will open then, it's hard for me to find some information of the consumption in different kinds of mode, I'd be appreciate if you could find a list of that. And as I know it integrates WIFI interface, we also need it, could you find me some independent WIFI module? Besides, we focus on low-power-consumption design, and it's the most import factor that we care.
Hi Jumping Mark,
For the various low power modes you can find the description of each in section 3.3.1 of the application note for power consumption. In the datasheet itself you can find the specifications as shown below:
Please, note that these values were measured using only the microcontroller, there were no external modules connected or powered during these tests. Once you connect different modules these values will vary depending on the consumption of each device added.
You can also find some information in chapter 12 of the reference manual. This sections describes power, clock and thermal management techniques supported by the chip.
Our examples that are available in the SDK for the i.MXRT1050, we use the following wifi modules:
Murata 1DX M.2 Module
Murata uSD M.2 Adapter
Thanks for your help, I got a lot of useful information for those websites. I wonder if there are any reference design with camera and WIFI module when I use i.MXRT1050.
You can download the example code and hardware guide for the evalaution board as there are two examples already made for the camera and there are also examples created for the wifi. As of now there is not one example that implements both.
