People keep asking about Zephyr + Wokwi. We need your README :)

Oh yeah!  In general, transferring huge amount of data over SPI is slow. There's an experimental way to short-circuit the low level SPI stuff and speed things up. Also,...

Meanwhile, I ran some benchmarks using the Wokwi Profiler. Seems like most of the ESP32 time is spent memcpy'ing and doing SPI stuff: 

Thanks! Yeah, the profiler is not available (yet) in VS Code, but I'm working on it! > Please see https://github.com/kartben/wokwi-zephyr-projects/tree/master/esp32c3-blinky Good catch, pushed a fix. Can you please test again?

Great! It's hard to tell whether Xtensa is going to be faster - it depends on the compiler and esp-idf. For instance, it might use DMA on the S2 (or...

Another update: got rid of the "rtc_init: o_code calibration fail" issue, so now the program should start much faster for C3 and S3 (it won't keep polling the RTC until...

Thanks for making it easy to reproduce - I found out it was a bug in the simulator (SPI hardware was not signaling the code it finished transferring data correctly)....

Thanks! Opened this request for [voting](https://wokwi.com/features?sort=newest#feature-1469127224)

Some initial findings: The WiFi (+Bluetooth 5.2) chip is Infineon CYW43439, and it is connected to the RP2040 over SPI. The pin assignment is as follows: | RP2040 Pin |...

Yeah, same here - it it stuck in the `_DoubleExceptionVector` handler. Not sure why simulation speed drops to 15% in this case, but the question is what happened just before...
