PSoC™ 4 Forum Discussions

Hi, Community,

Just a quick question, what is the standard name for the so-called "PG-VQFN-24(Infineon Package name)" in Automotive psoc 4000S?
I would like to know the correct information since the drawing is different from that of PSoC 4000.

I attached two figures, one is PSoC4000S and the other is PSoC4000.
Their difference is whether there is a vertical line in the side view or not.

I use cy8c4245AXI-483.

I have set up ADC SAR with 5 channels. 5 prototype boards have been assembled industrially.

I read the channels one by one. Among other things, a voltage between (-5V) and (0V) should be read out (channel 1). An inverter has been used directly on chip (see picture). The pins are connected accordingly.

Furthermore, a resistance setting (0-5V; channel 2) must be read out.

2 boards work as they should. 1 board returns wrong value from channel 2 (resistance). 2 boards deliver non-existent dips from e.g. 3V to 0V. And just after changing input voltage from 0V to -3V.

That is very critical for this control system.

I am now sure that it is somehow due to chip configuration or programming. Because I replaced a chip manually (another pin broke off during the test). It worked properly before. After the MC exchange, I noticed wrong values effect with the new chip.

I've already looked through all the chats and examples, but unfortunately couldn't find anything that can help me.

Can someone help me or give me a tip what could be wrong?

A snippet of the source code here where I read the values.

void adc_read_sw(struct swdata *ptrData)

{

    int16 adc_value_0 = 0u;        // ADC-CHANNEL 0     PIN 2[7]

    int16 adc_value_1 = 0u;        // ADC-CHANNEL 1     PIN 2[6]

    int16 adc_value_2 = 0u;        // ADC-CHANNEL 2      PIN 2[5]

    int16 adc_value_3 = 0u;        // ADC-CHANNEL 3      PIN 2[4]

  ....

//----------------------PT1        PIN 2[7]----------------------------------------------   

// ADC-CHANNEL 0 read

    ADC_READ_StartConvert();

    if(ADC_READ_IsEndConversion(ADC_READ_WAIT_FOR_RESULT) != 0u)

    {

        adc_value_0 = ADC_READ_GetResult16(0);

        adc_value_0 = ADC_READ_CountsTo_mVolts(0, adc_value_0);

        ptrData->p_adc_value_channel_0 = adc_value_0;    // pass value

    }

//    ADC_READ_StopConvert();

     CyDelayUs(50);

//--------------------------------------------------------------------

//---------------------- - 5V IN     PIN 2[6]----------------------------------------------   

//ADC-CHANNEL 1 read

//        ADC_READ_StartConvert();       

    if(ADC_READ_IsEndConversion(ADC_READ_WAIT_FOR_RESULT) != 0u)

    {

        adc_value_1                       = ADC_READ_GetResult16(1);

        adc_value_1                       = ADC_READ_CountsTo_mVolts(1, adc_value_1);

    }

    ptrData->p_adc_value_channel_1 = adc_value_1;    // pass value

//    ADC_READ_StopConvert();   

    CyDelayUs(50);

//--------------------------------------------------------------------        

//---------------------- R   PIN 2[5]----------------------------------------------   

// ADC-CHANNEL 2 read

    ADC_READ_StartConvert();

   if(ADC_READ_IsEndConversion(ADC_READ_WAIT_FOR_RESULT) != 0u)

    {

        adc_value_2                       = ADC_READ_GetResult16(2);

        adc_value_2                       = ADC_READ_CountsTo_mVolts(2, adc_value_2);

    }       

    ptrData->p_adc_value_channel_2 = adc_value_2;    // pass value

//    ADC_READ_StopConvert();

    CyDelayUs(50);

....... etc .....

    ADC_READ_StopConvert();

}

Dear supporter,

I would like to translate the following KBA. Could you confirm?

您好，请教一下，CYAT817AZS61-3A002作为TOUCH的驱动芯片，给其供电后，没有触摸，其INT引脚一直在不同的拉高拉低，应该还没有进入一个正常的工作状态，需要发什么指令让他进入正常工作状态，只有触摸时，才触发INT中断信号？

Dear Sirs and Madams,

We are developing PSoC4S with ModusToolbox.

That device number and IDE version used are as follows :

PSoC4S : CY8C4126AXI-S445

ModusToolbox : Version 3.1.0

Device Configulator : Version 4.10

We set the ECO settings of the device configurator as shown in the image below, and when we save, an error appears.

Frequency : 24.000 MHz

Accuracy : +/- 50 ppm

Drive Level : 20 uW

Equivalent Series Resistance : 60 Ohm

Parallel Load Capacitance : 11 pF

When I tried it here, I found that changing the DL value from 20uW to 21uW could avoid the error.

Frequency : 24.000 MHz

Accuracy : +/- 50 ppm

Drive Level : 20 uW => 21 uW

Equivalent Series Resistance : 60 Ohm

Parallel Load Capacitance : 11 pF

I think 20 uW is within the usable range according to the TRM calculation formula, but do you know why the error occurs?

Frequency : 24.000 MHz

Drive Level : 20 uW

Equivalent Series Resistance : 60 Ohm

Parallel Load Capacitance : 11 pF

Vpp = 0.49V is calculated from the formula listed in Architecture TRM.

When changing DL from 20uW to 21uW, Vpp = 0.50V. 

This issue can be reproduced not only with ModusToolbox, but also with PSoC Creator 4.4.

The descriptions of Architecture TRM and Register TRM are not consistent with the IDE.

Hi, I want to create a basic project for CY8CKIT-041S-MAX PSOC 4100S MAX PIONEER BOARD of changing the LED intensity using PWM to give it a breathing effect. I want to use the PDL library for this instead of HAL library. Can someone share a basic project that does this. I am very new to this board and ModusToolbox.
