I am running an Intel edison arduino board with Yocto, edison updated to libmraa 0.6.0. When I try to set up for analog in, I get the error message
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. 连接电位器中间针到针脚 A0,两边的针脚到 +5V 和接地。 This example code is in the public domain. 此代码示例位于公共域中。 https://www.arduino.cc/en/Tutorial/BuiltInExamples/AnalogReadSerial ...
I'm trying build and deploy simulink models to Arduino Uno using the "Simulink support package for Arduino hardware". I need to change the pin mode of pin "A0" to output and wirte to it. I know it's possible using the "Matlab support package" but the "Digital Output" block in the ...
When I'm using configurePin and readVoltage for analog pins using an Arduino Leonardo board I'm getting the following errors in R2023B: "specified Key type does not exist" and "the first input must contain a multiple of 2 elements.." See code snippe...
