This is literally my first forum post of any kind so let me know if I need to elaborate on anything.
As the title suggests I’m trying to send a snapshot image from the OpenMV cam to a webserver. This is to happen without the OpenMV Wifi Board (because they’re not in stock right now) and I own a NodeMCU. Frankly, I’m new to both devices and very weak at coding so I’m looking for some guidance.
Doing a little researching, I think I will do the following:
- SPI protocol between M7 cam and NodeMCU
- NodeMCU as master(?). This was decided solely on the fact that there exists example code for Arduino(M)-M7 cam(S) SPI comms. Though, from what I’ve seen, it’s more difficult this waY…?
- No AT command firmware, Arduino API for NodeMCU
Is this a good approach? So far I have been trying to simply send a message (“Hello World”) through SPI, with no luck. So I’m starting to doubt this method.
