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?

Re: ESP32-DevKitC32D
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.

Re: ESP32-DevKitC32D
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?

Re: ESP32-DevKitC32D
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...

Re: ESP32-DevKitC32D
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

Re: ESP32-DevKitC32D
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?

Re: ESP32-DevKitC32D
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.

Re: ESP32-DevKitC32D
Thanks!
I'll give that a try to see all the flash memory.

Re: ESP32-DevKitC32D
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.
