I have been unable to get my DHT11 or DHT22 to work with the Micropython DHT library. I get a ETIMEOUT every time I tried to do a measure() function call.

Is this broken in the latest release?

Has anyone tried the DHT Micropyton library in the current release? No matter what pin I try I always get a ETIMEOUT on measure(). I tried both DHT11 and DHT22 sensors.

I have had no luck getting my DHT11 or DHT22 to work on my ESP32's using Micropython's DHT library.

Measure() always fails returning a ETIMEOUT.

Any advice getting this to work?

I found a solution for benchmarking my controllers. Pystone_lowmem ESP32-PICO-D4 >>> pystone_lowmem.main() Pystone(1.2) time for 500 passes = 428ms This machine benchmarks at 1168 pystones/second >>> ESP32-DEVKITC32D >>> pystone_lowmem.main() Pystone(1.2) time for 500 passes = 432ms This machine ben...

For $6 more it's like night and and day.

The RPi Pico specs. says the following. The ESP32 version claims about a megabyte of RAM memory. Where is this extra RAM coming from on the ESP32?

Dual-core Arm Cortex-M0+ @ 133MHz
264KB (remember kilobytes?) of on-chip RAM

That allowed Hello World to show 4MB. No complaints by the flasher so there must be 4MB on both ESP32 boards.

Would you know how much ram the ESP32-Pico offers compared to the new ESP32-DevKitC32D board?

Is there an example program that would allow me to test the performance of my ESP32 controllers?

I would like to see how much faster (CPU & WIFI) my new board is over the ESP32-PICO.

Thanks!

I'll give that a try to see all the flash memory.

I don't understand why the Hello World example says I only have 2 MB of flash rather than 4 MB as the docs say.
