您好，当QSPI作为Slaver时，RX使用IfxQspi_FifoMode_combinedMove测试发现每次收到32bit数据进入中断，请问有没有办法接收8bit进入中断？

Hi all,

I am trying to configure ADC to transfer measurement results from several channels to DMA. But with my configuration, only the result which was configured lastly is transferred to DMA.

After some investigation, I found that interrupts are not triggered. What am I doing wrong?

Here is how ADC channels are configured:

/* ADC Interrupt Service Routine */
IFX_INTERRUPT(ISR_ADC_result1, 0, 20); // Not triggered
IFX_INTERRUPT(ISR_ADC_result2, 0, 21); // Not triggered
IFX_INTERRUPT(ISR_ADC_result3, 0, 22); // Triggered
//.....

#define CHANNELS_NUM        3
#define AN17_CHID           1 /* Channel ID for pin AN17                          */
#define AN20_CHID           4 /* Channel ID for pin AN20                          */
#define AN21_CHID           5 /* Channel ID for pin AN21          */
IfxEvadc_Adc         g_evadc;
IfxEvadc_Adc_Group   g_adcGroup;
IfxEvadc_Adc_Channel g_adcChannel[CHANNELS_NUM];/* EVADC channels handle array                      */
uint8 g_grp2channels[CHANNELS_NUM] = {AN17_CHID, AN20_CHID, AN21_CHID}; /* AN17, AN20, AN21 channel IDs array       */

//...
void initAdc(void)
{
    /* Create configuration */
    IfxEvadc_Adc_Config adcConfig;
    IfxEvadc_Adc_initModuleConfig(&adcConfig, &MODULE_EVADC);

    /* Initialize module */
    IfxEvadc_Adc_initModule(&g_evadc, &adcConfig);

    /* Create and initialize group configuration with default values */
    IfxEvadc_Adc_GroupConfig adcGroupConfig;
    IfxEvadc_Adc_initGroupConfig(&adcGroupConfig, &g_evadc);

    /* Setting user configuration using group 2 */
    adcGroupConfig.groupId = IfxEvadc_GroupId_2;
    adcGroupConfig.master = IfxEvadc_GroupId_2;

    /* Enable queued source */
    adcGroupConfig.arbiter.requestSlotQueue0Enabled = TRUE;

    /* Enable all gates in "always" mode (no edge detection) */
    adcGroupConfig.queueRequest[0].triggerConfig.gatingMode = IfxEvadc_GatingMode_always;

    /* Initialize the group */
    IfxEvadc_Adc_initGroup(&g_adcGroup, &adcGroupConfig);

    /* Create channel configuration */
    IfxEvadc_Adc_ChannelConfig adcChannelConfig[CHANNELS_NUM];

    for(uint16 idx = 0; idx < CHANNELS_NUM; idx++)
    {
        /* Initialize the configuration with default values */
        IfxEvadc_Adc_initChannelConfig(&adcChannelConfig[idx], &g_adcGroup);

        /* Select the channel ID and the respective result register */
        adcChannelConfig[idx].channelId = (IfxEvadc_ChannelId)(g_grp2channels[idx]);
        adcChannelConfig[idx].resultRegister = (IfxEvadc_ChannelResult)(g_grp2channels[idx]);

        adcChannelConfig[idx].resultPriority = 20 + idx;

        /* Initialize the channel */
        IfxEvadc_Adc_initChannel(&g_adcChannel[idx], &adcChannelConfig[idx]);
    }
    
    for(uint16 idx = 0; idx < CHANNELS_NUM; idx++)
    {
        /* Add channel to queue with refill option enabled */
        IfxEvadc_Adc_addToQueue(&g_adcChannel[idx], IfxEvadc_RequestSource_queue0, IFXEVADC_QUEUE_REFILL);
    }
    
    /* Start the queue */
    IfxEvadc_Adc_startQueue(&g_adcGroup, IfxEvadc_RequestSource_queue0);
}

The code is based on examples:

Dear support team,

If the ADC reference supply voltage exceeds the ADC power supply voltage, will there be any impact/change in the the TUE min., max. values specified in the datasheet? TC29xBC Microcontroller datasheet, specifies  VADC parameters ( Table 3-27) over the ADC supply voltage (VDDM) range of 4.5V to 5.5V and in this table maximum Analog reference voltage is specified to be (VDDM + 0.05V) so can i say that if my VREF = 5.1V and VDDM = 4.9V i.e. VREF > VDDM + 0.05V, ADC accuracy parameters will still be the same as mentioned in this table?

Thanking you in advance.

Dears：

    At present, I am using the autosar tool to develop TC397. When I configure the PORT module, I found that there is a correspondence between the value of PortPinId and PORT_0_PIN_0, but I did not find this correspondence in the manual, so I hope you can help me answer it. , the corresponding relationship between the two.

thanks！！！
