Down arrow? I don't think so. What's that for?

Re: ADC positive offset on 0V

@ESP_Faye Things i've tried: Switched the ESPs between boards to to be sure that isn't the circuit, the problem followed the ESPs. Wrote a simple code using system_adc_read_fast(), wifi off and got the same result, with the ADC pin grounded it reads 10-12 points. Yesterday I've built 3 more boards, ...

Re: ADC positive offset on 0V

Hi, Could you have a try with the latest ESP8266_NONOS_SDK ? Thanks for your interest in ESP8266! Faye, same problem, same offset. I'll try on more boards, but I got 50% working and 50% with this problem and I'm always checking the voltage at the pin with a calibrated equipment to be sure. Any thou...

ADC positive offset on 0V

I'm getting a very annoying problem: I have a project using esp12e and on some boards I got wrong ADC readings(using system_adc_read SDK 2.0.0 NONOS), even when I ground the ADC pin I can read a value ~10mV. I tried to change WiFi modes(all of them) but didn't changed significantly. Any help is appr...

Re: Parsing json: trouble with booleans and negative numbers

Soup, did you solved this problem? I'm facing the same issue. Looking into the contiki source code(from where I believe that the ESP code came from), it should handle the atomic types, NULL, TRUE and FALSE. But the ESP code returns 0 and there's a error element inside the jsonparse_state struct, tha...

JSONTREE_ARRAY with dynamic size

I'm working with JSON and I want to send a log, the obvious way is to use a JSONTREE_ARRAY, but the log size is dynamic, and as far as I noted, JSONTREE_ARRAY's size is static. Any ideas or workarounds?
