Yes ! now, I'm testing any unit that is connected to AC to make sure there is no AC on the DC side.

i should start doing that too, good call
no idea if they are half decent...

@tzapu reviews of some cheap power supplies can be found here http://www.lygte-info.dk/info/indexUSB%20UK.html
wow @larsenglund thank you very much
Holger Lembke
tach auch.
Is there something to generate a stable 32k frequenz? ticker-lib does not give more than ms... and digging in the source lead to not much... any idea?

have you tried the other timer?
what is the duty cycle that you want to acheave
Holger Lembke
50% is ok
I have tried to upload a image(2MB) to twitter, it takes 260 sec(timeout is 270sec) with client.write(buff, size).

Hi, I'm trying to use WiFi.disconnect() to clear previously stored WiFi connection parameters, but the ESP crashes when I call this method, any idea why this happens?
anyone doing the new rtos? I'm about to move all my code over
Michael Miller
@physiii Why?
Regarding the WiFi.disconnect() crash, when I call this method, this is the crash log I'm seeing:

What is the best practice / simplest way of enabling and disabling debug printouts? Currently I use

#define DEBUG_PRINT(x) Serial.print(x)
#define DEBUG_PRINTLN(x) Serial.println(x)
#define DEBUG_PRINTF(x, ...) Serial.printf(x, ...)

and then just empty-define them when I want to turn off debug printouts...

there s something in the documentation of the core that would let you enable /disable debug using the arduino ide tools menu
if that helps
Lars Englund
@tzapu thanks!
Hmm.. is this related to me just updating to arduino 1.6.8 and esp 2.2.0?
In file included from D:\bitbucket\exxact\Firmware\EDWD\EDWD.ino:11:0:

C:\Users\englund\AppData\Local\Arduino15\packages\esp8266\hardware\esp8266\2.2.0\cores\esp8266/Arduino.h:42:14: error: expected identifier before numeric constant

 #define HIGH 0x1

after that follows alot of errors about the expansion of the macro HIGH..
The wifi scan example compiles just fine
@larsenglund no probs, don t know about the other thing..
Lars Englund
Apparently an update to the Keypad library did a #define CLOSED HIGH in Keypad.h which seemed to be the source of the problem. Redefining it to #define BTN_CLOSED HIGH made the errors go away..
It was colliding with a definition of CLOSED in some WiFi stuff..

@all the Benoit Blanchon ArduinoJson users: Only a question:
File configFile = SPIFFS.open("/config.json", "r");
  size_t size = configFile.size();
  std::unique_ptr<char[]> buf(new char[size]);
  StaticJsonBuffer<200> jsonBuffer;
  JsonObject& root = jsonBuffer.parseObject(buf.get());
    bool a = root["a"];
  bool b = root["b"];
  Serial.print("A: ");
  Serial.print("B: ");
config.json contents:
{"a": false, "b": true}
Why the above code returns both values as false?
A: 0
B: 0
I've checked the file on the spiffs, and it looks good.
Helio Machado
Going offline for half an hour. See you later!
Helio Machado
Silly error!
I missed to add configFile.readBytes(buf.get(), size);

For a while now I try to build uploading to my esp-12 with CH340T. Works great with manual reset/prog-jumper.
or better: IDE/esptool thinks it is uploading, ESP-12 seems to see something, too. But reset does not work and serial monitor is dead.
Looking on the data lines (reset and gpio0) it looks like everything goes totally wrong.
