Controlling your World the Easy Way

The modem not being in sleep mode is probably a documentation issue, maybe a chip bug. I recommend that you post a question on ESP32.com on how to put the modem to sleep.

I'll try to reproduce the issue at my work place and see if I can come up with a solution.

Thanks a lot. The board id of ezsbc32-01 is perfect.

The board has an RGB LED that is connected to the ESP32. The pin numbers are as follows:
Red LED pin 16
Green LED pin 17
Blue LED pin 18
A low on those pins turns on the appropriate LED.

I've had a report that the USB connector on the module detached during normal use. A test of some modules shows that the solder joint between the USB connector mounting tabs and the PCB can shear if the cable in the USB connector is lifted away from the PCB. The underlying cause is that the openings...

From your post I can't decide if you bought the module or the PCB with the module installed. I do all my testing on the PCB with the module installed so if you bought the module only it may not apply directly. When I do an AD-conversion with a simple Arduino program I get good readings and an static...

It works well. I changed the delay to 20ms and it looks even better. A piece of white paper in fron of the LED blends the colors very nicely. I see the original author placed the code in the public domain. There are still some things that don't work in the Arduino environment. The worst annoyance is...

I use v1.8.x for testing. Versions from around 1.6.10 seem to work properly. YMMV

This code is loaded on the bords before they are shipped. The WiFi example listed here https://learn.sparkfun.com/tutorials/esp32-thing-hookup-guide#arduino-example-wifi works on the board. The button to the left of the Micro-USB connector works as the button in the description. Daniel /* This examp...

The schematic can be downloaded here.

You need to choose a module with the same memory size as the one you have. The ESP8266-12E has a bigger flash memory than the ESP8266-07 that is on the breakout board you purchased. You have to choose 'Generic ESP8266 Module' from the Board Manager menu. Also, you have to press and release the Reset...

To get a decent working environment try using CoolTerm. It works reasonably well. The reason why pasting into the window doesn't work well is that I convert the text to tokens as they are typed and save them to memory. The conversion to tokens is fast but the saving to memory is slow and tricky. I h...

That's an impressive minature! How long did it take to build? And how do you move the trucks and cars?

Here's another Finnish work of art. http://pokitto.com/index.php?id=15 The project grew out of a module that Jonne bought from me a while ago.

Do you think the speed will suffice for scrolling ten or more 8x8 dot displays (address+data totals 1280 bits) in real time? I assume this can be done by outputting string data on the serial pins? The MAX7219 module needs a clock pulse for each data bit: "For the MAX7219, serial data at DIN, s...

I will look into it today and let you know by tomorrow.

You can mount the regulators in any orientation. The only effect is that they may run hotter by a degree or two, nothing serious. Typically most of the heat is conducted away through the pins and PCB. When you order, just send me an email asking for the pins to be supplied unsoldered and I will incl...

Try using the IFF statement. It is faster. Also, brackets may speed up the evaluation.
