PSoC™ 4 Forum Discussions

Hello,

I'm designing a proximity sensor on a pcb.

The first design I have got is 4 sensors pads ( 20mm*20mm) next to each other and they are used as a proximity sensing which is working ok.

But I wanted to try with a loop trace on the pcb instead of pads which are normally for touching and not proximity sensing?!

Therefore, I wanted to add some hatch pattern on the top and bottom layer ( 2 layers pcb).

Do I need to put a hatch inside the loop?

Also I'm close to a metallic object so which signal should I drive on the top and bottom layer? I'm a bit lost between shield or ground?

Thanks in advance for your time,

Alex

Hi everybody, we would like to use I2C FM+ on PSoC4.

Is it mandatory to use "I2C FM+" slew rate on I2C pins or the I2C FM+ specification can be met also using fast slew rate for example?

As far as I've understood the "I2C FM+" slew rate is only available on PSoCs with overvoltage tolerant IOs in 4100M, 4200M and 4200L families, while we would like to possibly use the 4100S or the "4100S plus" families.

Many thanks in advance for your support.

I am using the compact iprintf function created by you guys.

The function looks like this :

void iprintf(char8 *pszFmt,...)

{..

}

I wanted to add some more parameters to the function so I could use it for both uart and flash.

But when adding the new parameters, the variables i am adding to %d start to get distorted on UART print.

e.g

void iprintf(uint8 flag1, uint8 flag2, char8 *pszFmt,...)

{..

}

when i do :

uint32 variable =100;

iprintf(flag1,flag2, "some string : %d \r\n", varibale);

the value of the variable is printed wrong.

Hi!

I am now using PSoC4 4100S Prototyping Kit and trying to figure out on how slider works.

It's a bit technical though.

1. How does the slider decide its position?

I know it is related to the difference between each sensor's raw counts but I need a further and detailed explanation.

Here I show the graph I took from CapSense Tuner.

I set the maximum position of slider to 200 and took graph while slowly slide my finger from SLD0 to SLD5.

2. On CapSense Tuner, what is the difference between Asynchronized and Synchronized in Communication mode?

Thank you very much,

Hello,

I have a device with a Cypress semiconductor that is running the UART_to_BLE_Central project.  I would like to modify the code that is filtering by Manufacturer data and put a different filter.  Would this be possible?  Would it be possible to read other parameters passed from BLE at CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT ? I pasted a copy of this code that is causing the issue.

I want to be able to make a BLE connection to an iOS peripherial mobile app.  Right now I only get this to work if I remove the manufaturing data condition show below. Unfortunately as a result, it also connects to any other peripheral devices in the area.  And this is impacting the reliabitly and quality of the connection.

File: app_Ble.c

case CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT: 

            advReport = (CYBLE_GAPC_ADV_REPORT_T *) eventParam;

            /* check if report has manfacturing data corresponding to the intended matching peer */

            if((advReport->eventType == CYBLE_GAPC_SCAN_RSP) && (advReport->dataLen == 0x06) \

                    && (advReport->data[1] == 0xff) && (advReport->data[2] == 0x31)  \

                    && (advReport->data[3] == 0x01) && (advReport->data[4] == 0x3b) \

                    && (advReport->data[5] == 0x04))

            {

                peerDeviceFound = true;

                memcpy(peerAddr.bdAddr, advReport->peerBdAddr, sizeof(peerAddr.bdAddr));

                peerAddr.type = advReport->peerAddrType;

                #ifdef PRINT_MESSAGE_LOG 

                    UART_UartPutString("\n\r\n\rServer with matching custom service discovered...");

                #endif

            }         

            break;  

Any ideas would be greatly appreciated.

Thanks,

Rohan
