Code Example for ADC16 IRQ Handler

[pcpro178]

Where can I find a code example for the ADC16 IRQ handler setup and usage?  Code examples seem severely lacking on this platform.  I am using Kinetis with KSDK 2.0 and MKL17Z256VLH4.

Hi Jim

Code for ADC interrupt, ADC DMA, ADC level interrupts available in the open source project at links below. ADC is simulated in Visual Studio for more development efficiency.
All code will run on any Kinetis without the usual porting issues.

Thanks, but this looks like it is using a third-party library.  I am using the KSDK 2.0 library from NXP.

Hi Jim

If you are restricted to KSDK you may be able to find someone who has added the missing features in the KDSK forum: https://community.nxp.com/community/mcuxpresso/kinetis-software-development-kit
or you may need to upgrade to SDK 2.3 which includes a basic interrupt example.

If you need to upgrade it yourself manually it is only two additional operations as follows (using simple end of conversion interrupt):
1. Enter the ADC's interrupt handler into the vector table and enable this interrupt with its required interrupt priority
2. Set the ADC_SC1A_AIEN bit in the ADC0_SC1A register

Then start the conversion as normal and the interrupt will fire when it completes.
