Fantastic! It's great to have some actual measurements of the EPS8266. This is actually one of the bigger flaws if we want to measure a "slice" of WiFi because the...
If I'd put more work into it, I'd try to make the software upload OTA or something similar. Or flash them all at the same time (not sure if they...
But you need CS for each device if you want to fetch data by device. This would require 1. many traces on the PCB 2. a master unit with n...
Or do you mean to flash the devices via SPI? That would actually be a cool idea. But how do we separate all the devices after flashing? :D I mean...
TBH that would be a very cool experiment to load firmware to many ESP from one central SPI flash. I wonder if someone has done it before.
I think we could also use the the ESPs for that. by connecting a gpio to the reset button of the next ESP, we can upload firmware one after another...
Ah ok this is interesting. They daisy chain the MISO and MOSIs. Never seen that in action, actually. I'm wondering if SPI supports that natively or if they need special...
Another option would be to use a GPIO expander like mcp23016. This would either give us more CS pins or a controlled reset for each ESP to flash them. I2c...
Why should fiberglass affect the radiation pattern? I thought it would be very similar to air in terms of RF transparency. The 26mm is more a compromise between how many...
@javerik I'd say no. I'd think we should keep it as platform independent as possible. Let's keep SPI and EEPROM out if possible. If we can use the external libraries...
