Re: Ethernet used as slave RMII ?

Basically esp8266 is esp8089 plus some extra features so using esp8266 in esp8089 mode just ignores those features. Same with firmware, it is just basic radio firmware, more basic than AT firmware. Just push raw data back and forth because Linux host is faster processing. It has nothing to do with e...

Re: Do you think we are playing games here?

Makes sense. So DMA spi operations are possible though?

Re: ESP32 Free Heap

How does the separate IRAM and SPI cache affect the ability of threads/tasks/ISRs to run on both cores dynamically? Thanks

Re: ROM functions

The ROM may not be finalized at this point and the SDK probably isn't linking to ROM functions for debugging purposes.

Re: ESP32 Free Heap

Fyi, do not take this as an indication on the amount of memory that will be available in the final SDK and on the final ESP32 chip. Because of the memory map of the ESP31, we only use a specific bit of memory (the shared RAM) as heap. Don't quote me on this, but I estimate the free heap in the ESP3...

Re: Be VERY careful assembling beta boards ... I ruined mine

Planning on using solder paste and hot air to avoid this problem.

Re: ESP32 breakout board spotted in the wild

Nice to see they are shipping out. Wonder if they are shipping all at once or in smaller batches.

Re: [Documentation Release] PCB of ESP32 Module

So ESP31 vs ESP32 Pins 36-45 are different pinout, mostly just rearranged. ESP32 loses Vdigital supply input which is used for digital IO logic levels? Instead is combined with Vpll? Or Vcore? ESP32 gains GPIO23 pin @ pin #42 No labels for RTC_GPIO pins yet? Pins 10 & 11? GPIO #1 is mirrored on two ...
