Introduction

This example uses the ADC to perform an ADC SOC conversion triggered by software.

The example does the below

• Configures SOC0 to be triggered by software.
• Configures ADC interrupt 1 to be generated at end of conversion of SOC0.
• Forces the SOC0 through software and waits for completion by polling ADC interrupt 1 status.

External Connections

• ADC0_AIN0 pin should be connected to signals to be converted.

AM263X-CC

When using AM263x-CC with TMDSHSECDOCK (HSEC180 controlCARD Baseboard Docking Station)

• Feed analog input (non-zero voltage) to HSEC Pin 12

AM263X-LP

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am263x-cc, am263x-lp
Example folder	examples/drivers/adc/adc_soc_software/

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Establish connections as mentioned in External Connections section
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
• View the ADC conversion results in UART console logs
