Arduino: ADC_MODE doesn't work

Created on 12 Mar 2016 · 12Comments · Source: esp8266/Arduino

I'm trying to get use of ESP.getVcc(), so I added the following line, per documentation.

ADC_MODE(ADC_VCC);

But I get the following error messages during compilation:

Arduino: 1.6.8 (Mac OS X), Board: "NodeMCU 1.0 (ESP-12E Module), 160 MHz, Serial, 115200, 4M (3M SPIFFS)"

For the original error I pasted, the line number is not 1 because I was moving it around to see if it would fix it.

mattwilliamson on 12 Mar 2016

This seems to be caused by arduino-builder not generating correct forward declarations for functions marked with extern C.
I'll see if we can implement a workaround for this, since the just-released arduino 1.6.8 is affected by this issue.

igrr on 12 Mar 2016

Thanks!

At the moment plain

#include <Arduino.h>

ADC_MODE(ADC_VCC);

void setup() {}
void loop() {}

cannot get compiled with 1.6.8

mozgy on 13 Mar 2016

I've confirmed that downgrading to Arduino 1.6.6 bypasses the issue for now. Thanks for looking into this.

mattwilliamson on 17 Mar 2016

I had the same Problem with : ADC_MODE(ADC_VCC); and Version 1.6.8
My workaround:
Add a new Tab with file adc.h
with one line:
ADC_MODE(ADC_VCC)

add
#include "adc.h"
as first include in first tab.
