PSoC™ 5, 3 & 1 Forum Discussions

Hi All,

I have a MFRC5222 and a PN532 board for rfid.

I am trying to implememnt RFID on my project using the psoc5lp but am having difficulty. I tried to search online for solution with no luck.

Both boards allow I2C or SPI but I have tried bot and am hitting a brisk wall.

Can anyone give me some advice? I have allot of experience with i2c but even with my logic analyzer with decoder I cant find the problem.

As for SPI, I dont really have any experience with it.

Best Regards,

Rob Berry

Hello together,

i have an SDP601 Sensor http://www.mouser.com/ds/2/682/Sensirion_Differential_Pressure_SDP6x0series_Datas-767275.pdf

The Sensor uses I2C to communicate. I have connected the Sensor to a PSOC 5LP Development Board but it doesn't work. 

#include <project.h>
#define I2C_SLAVE_ADDRESS    (0x40)
    uint8 temp;
    uint8 status;
    uint8 Sensor_Command = 0xF1;              // Command for Sensor
    uint8 Sensor[3];
    uint8 i= 0;
    uint8 j= 0;
int main()
{
    CyGlobalIntEnable; /* Enable global interrupts. */
    LCD_Start();
    I2C_Start();
   
    status = I2C_MasterSendStart(0x40, I2C_WRITE_XFER_MODE);
    if(I2C_MSTR_NO_ERROR == status)   /* Check if transfer completed without errors */
    {         
        status = I2C_MasterWriteByte(Sensor_Command);
    }
    status = I2C_MasterSendStart(0x40, I2C_READ_XFER_MODE);
   
        Sensor[0] = I2C_MasterReadByte(I2C_ACK_DATA);
        status = I2C_MasterStatus();
        Sensor[1] = I2C_MasterReadByte(I2C_ACK_DATA);
        status = I2C_MasterStatus();
        Sensor[2] = I2C_MasterReadByte(I2C_ACK_DATA);
        status = I2C_MasterStatus();
    I2C_MasterSendStop();      /* Send Stop */
    LCD_PrintInt8(Sensor[0]);
    LCD_PrintInt8(Sensor[1]);
    LCD_PrintInt8(Sensor[2]);
 
   
    while(1)
    {
   
    }
}
 

I tried many other code but it will not work. What can I do? Can you write working example Code?

SCL is connected to P0[0] SDA is connected to P0[1]

The LCD is connected to P2[0]-P2[6]

Hi Experts

only MDIO slave/device is supported, right ? 

How about MDIO master?

Appreciate you answers.

Hello,

I use a custom board with a PSOC5. Until now, the board run perfectly. From one day to the next the board has no function - supply is OK, we had no overvoltage, etc ...
I can not successfully program this board. The current consumption of the device is 26 mA at 12V (with a voltage regulator down to 3.3V)

PSCO Creator OUTPUT :

Programming started for device: 'PSoC 5LP CY8C5667LTI-LP041'.
Device ID Check
WARNING! JTAG/SWD communication for PSoC3/5 is not stable with the clock above 3.2 MHz! Please select lower clock option in case of failures.

Error: dbg.M0023: There was an error while programming the device: PSoC Programmer reported error (103 - Failed to program the chip!)

Does anyone have an idea or solution approaches?

Thank you
