Re: HC-SR04 using RMT - very fast

I'm not sure if this is FP32 or maybe better to use FP64 e.g. double.
Maybe optimized FP16 (manual calc?) would work fine as well

Re: I2S-parallel example: Drive a 64x32 display

I just received exactly same panel - 64x32 P4 with those crazy connectors. What code example (esp-idf) should I use to get it working.? I have two links but not sure if those are latest https://github.com/ESP32DE/I2S_parallel_example_drive_a_64x32_display https://github.com/pixelmatix/esp32_I2sParal...

Re: What would you like to see in The Next Chip?

Faster ram and much more ram available in continuous blocks of memory would be a dream.
Also increasing carrier frequency for RMT up to 433Mhz would help greatly.
Mandatory thing - make better and clear documentation for I2S !!

Re: What download speeds are available on WiFi?

I was able according to my calculations - to get bandwidth of 9 megabyte/s through STA mode and router in close proximity around 1-2m from the module. The bandwidth drops with the distance but amplified signal should work pretty fast. However I had to program a pure TCP socket-to-socket connection w...

Not quite sure looking at picture - but is the chip size 2x bigger?
More cores? )

Re: Control 5V relay with ESP32 DEVKITC

Depends what relay. I was able to control 5V relay with multiplexer without any problems.
Also adding 3V optocoupler will allow such control

Compiler and IntelliSense

I work with some nice editor that could be used as very basic GUI for development The only thing that would make the stuff easier would be to add intellisense to it because I have a full source code So my question is - where are the necessary symbols for classes and methods? What do I need to do tha...

Re: Efficient Coding Considerations

Maybe some people would be interested in non-Adafruit graphics library project just for ESP
I also like the idea of RTOS on ESP8266 which will make those MCUs very attractive on market and practical for engineers
For now however there is no CMake for 8266
