How to use 5 inputs and 1 output
Hi, I want to use 5 analogue inputs to mbed board and 1 output from mbed board to DAC MCP4822. I used pin 15, 16, 17, 18 and 20 as 5 analogue inputs to mbed board and used pin 19 for output from mbed to DAC. In code I have written the configuration as
MCP4822 MCP1(p5, p7, p19);
AnalogIn ADC_1(p15), ADC_2(p16), ADC_3(p17), ADC_4(p18), ADC_5(p20);
Is it right?

The MCP4822 is an SPI DAC. So you need to connect it to one of the SPI ports of the mbed. The mbed's DAC is not used in your setup.
