Re: Interface Library Discussion

Just so I don't go off on a tangent and i understand correctly. 1. The OpenMV cam is a 'slave' in this use case. it's basically doing it's own thing, but sends something to the host when queried? i say 'slave' because it's not really designed to act as a slave; whereas this sounds more like a co-pro...

Re: Battery Charge Level / Gauge

This is also a good read. Hardware side: https://docs.openmv.io/library/pyb.ADC.html Software side: If you can get the ADC vref, you can get the base voltage via the voltage divider (100/100) above by using the following formula will give you a decently accurate (adc reading of battery/4095)*2(for t...

Re: ESP32 as a co-processor(slave)

ESP32SPI_wifimanager.py attached. can't include it via code as the forums hate it for some reason. if i can ever get around to setting up an environment to compile my own firmware, i'll get to work on the C driver for micropython/openmv; but this at least allows anyone who wants to drag and drop cod...

ESP32 as a co-processor(slave)

Posting this here in the event anyone wants to go down the route I needed to. i hope this is allowed, and wish i had a better way to present this. I have a ton of ESP32's laying around, so why not use one as a co-processor as both Adafruit & Arduino do. don't be confused, the ESP32 is a Slave device...

Re: picture gets dark, when switching IR leds on

i can confirm this happens to mine as well. i tried flashing the LED's as well with the snapshot and it made it marginally better, but in full dark or light, turning on the IR leds effectively over exposes the entire image.

Re: printing to OLED display

Do you want the example shipped with the IDE? that would be nice, but i am referencing the ssd1306 driver you added to the libraries. https://github.com/openmv/openmv/blob/master/scripts/libraries/ssd1306.py The code only supports SPI communication. since it is not pulled from the main micropython ...

Re: how to send image to server by post to http?

Thanks.By the way,Is the ATwinC1500 hardware itself not supported SSL or just does not transplant the relevant ssl code in OpenMV3? No the hardware supports it, but currently there's no way to download certificates to the module flash. Sorry to resurrect an old post. Given the wifi shield uses the ...
