i configured adc mutiple channe as below but i iam not receiving interrupt from adc0

[sandeepc]

hi i need read 24 channels for my end applicaton as of now iam trying to read 2 channels if i am done with adc 2 channels so that i can understand to do 24 channles 

SDK DETAILS

S32 Design Studio for S32 Platform
Version: 3.4
Build id: 201217 (Update 3)

as of now iam configured as below

adc converter config and channels PTA 0 AND PTC14

const adc_converter_config_t adc_config_1_ConvConfig0 = {
.clockDivide = ADC_CLK_DIVIDE_4,
.sampleTime = 255U,
.resolution = ADC_RESOLUTION_12BIT,

.trigger = ADC_TRIGGER_HARDWARE,
.pretriggerSel = ADC_PRETRIGGER_SEL_PDB,
.triggerSel = ADC_TRIGGER_SEL_PDB,
.dmaEnable = false,
.voltageRef = ADC_VOLTAGEREF_VREF,
.continuousConvEnable = false,
.supplyMonitoringEnable = false
};

const adc_chan_config_t adc_config_1_ChnConfig0 = {
.interruptEnable = true,
.channel = ADC_INPUTCHAN_EXT12
};

const adc_chan_config_t adc_config_1_ChnConfig1 = {
.interruptEnable = true,
.channel = ADC_INPUTCHAN_EXT0
};

PDB CONFIG 

/*! @brief ADC pre-trigger configurations */

Hi sandeepc,

When debugging the project, setting a breakpoint in ADC_IRQHandler cannot pause it?
By they way, have you refer to those examples?
Example S32K148 PDB0-PDB1 ring S32DS3.4 RTM4.0.3
Example S32K148 PDB0-PDB1 ring DMA S32DS3.4 RTM4.0.3

Best Regards,
Robin
