ESP8266 Community Forum

- Wed Jun 01, 2016 8:12 pm #48428 Seems kind of hard to find an answer on how much data throughput one can get from WiFi to digital data (i.e. inbound). I suppose one could either use the GPIOs as outputs or try to utilize the SDIO bus. In the case of GPIO I can't seem to find any indication on how fast one could toggle these. I suspect it's a function of how fast the processor can execute a put to port instruction. For the SDIO I'm not sure if I'm getting myself into some special protocol that will prevent me from just streaming data out quickly. If no special protocol required and it would allow data to be pushed out quickly it's not clear what features the esp8266 provides to stream data out to the SDIO. Some kind of DMA would be nice.

Anybody know where I can find documents that would answer these types of questions?

Thanks
