MAX32630FTHR ADC

I am trying to work with the ADC. I define the analog inputs as follows:

AnalogIn ch0(AIN_0); ADC input AnalogIn ch1(AIN_1); ADC input AnalogIn ch2(AIN_2); ADC input AnalogIn ch3(AIN_3); ADC input

I get the following compiler error:

/media/uploads/PowerIC/compiler_error.png

I could not find an example, so I am basically porting mBed ADC code that works on other mBed enabled platforms. Is there something different on the MAX32630FTHR?

Question relating to:

Maxim's microcontrollers provide low-power, efficient, and secure solutions for challenging embedded applications.

Bill, The path in your error message calls out an old development library. Please change to the official mbed-os library. Our latest examples at our MAX32630FTHR APPS wiki page all use the official library now.

This example uses the analog inputs:

Thank you Greg! Works like a charm now.

Hello Bill,

Please see the following example, https://developer.mbed.org/users/j3/code/MAX32630FTHR_ADC_Example/file/047c43d8b360/main.cpp

Links to analogin_api.c for both mbed-os and mbed-2.0 showing the configuration of an ADC channel when using the mbed API.

https://developer.mbed.org/users/mbed_official/code/mbed-dev/file/b23ee177fd68/targets/TARGET_Maxim/TARGET_MAX32630/analogin_api.c

I hope this helps.

Thanks, Justin

Bill,

I verified the example above with mbed-os as well. You can delete the reference to 'mbed' in the project above and include 'mbed-os' if that is what you are using.

Thanks, Justin
