This might be more an Android programming question than PSoC but if anyone has experience with FLOAT data:

Using a characteristic with Field, New Field, Type FLOAT, Length 4.

As suggested here, the float is cast (void) on writing in PSoC:

            notificationHandle.value.val = (void *)&Ah;

In Android, reading it with     float c = getFloatValue(BluetoothGattCharacteristic.FORMAT_FLOAT, 0);

only gets INFINITY.    The data is being transmitted, because if I get it as 4 bytes and convert to IEEE 32 bit float, it's correct (that was a two aspirin coding job for me;)

03-25 19:11:43.158: D/BluetoothGattActivity(6732): AH Got 229,242,63,63

in hex those are:  E5 F2 3F 3F

AH should be around 0.752

The above converts to:   0.749800026417
 

This is more of an observation than a question, but I noticed that Cypress is not in the Bluetooth Developer Portal list of companies that provide Bluetooth Smart development solutions.

https://developer.bluetooth.org/DevelopmentResources/DevelopmentPlatforms/Pages/Development-Platforms.aspx

They provide a mailto link at the bottom to contact the Developer Site administrator for those who want to be added to the list, and I figured it might be something that made sense for Cypress to pursue.

Hi,

Im having huge trouble trying to interface the newhaven LCD display which has a ST7565P LCD driver to the PSOC 4.

http://www.newhavendisplay.com/nhdc12864a1zfsbfbwhtt-p-3895.html

I have an SPI block and 3 output pins on my "top design"

3 output pins - Reset, A0, CS

On the SPI, i used the mosi (SCL) to connect to the SCL on the LCD, while miso(SDA) to the data pin on the LCD

I have an initialization code that runs like this... I basically took this off newhaven's website..

int main()
{
    /* Initialization */
    XBEE_Start();                //starts the Xbee UART
    SPI_Start();
    LCD_Initialization();

...................

}

void comm_out(unsigned char j) //Command Output Serial Interface
{
    unsigned int n;
    CS_Write(0);
    A0_Write(0);                //A0 = Command
    for(n=0; n<8; n++){
         j <<=1;
     SPI_mosi_s_Write(0);
     SPI_miso_s_Write(j);
     CyDelayUs(1);
     SPI_mosi_s_Write(1);
    }
    CS_Write(1);
}

void LCD_Initialization(void)
{
    comm_out(0xA0);                        //RAM->SEG output = normal
    comm_out(0xAE);                        //Display OFF
    comm_out(0xC0);                        //COM scan direction = normal
    comm_out(0xA2);                        //1/9 bias
    comm_out(0x2F);                        //power control set
    comm_out(0x21);                        //resistor ratio set
    comm_out(0x81);                        //Electronic volume command (set contrast)
    comm_out(0x2F);                        //Electronic volume value (contrast value)
}

Hi,

See the attached image.  When I am debugging the project, the processor gets inside an if statement that it absolutely should not be able to.  I must be missing something very simple, but this is baffling...

Thank you,
Tom

I'm using the MiniProg3 to program my PSoC4200. In the application the PSoC is powered by 5,21V. The program process fails. Acquiring the PSoC device fails.

In the GUI PSoCProgrammer 3.23. the voltage is displayed to be 5000mV. Because the voltage seemed to be a bit high, I lowered the voltage until it is 4,5V. Programming the PSoC at this voltage works. With higher supply voltage the PSoC device can not be acquired.

Settings: Protocol: SWD; Voltage: 5.0V; Connector: 5p and 10p is tested; Programming Mode: Reset

Next step I tried to use 3,3V supply voltage. The settings in PSoCProgrammer is changed to 3,3V. Flashing the device is working without any problems.

The MiniProg is directly connected via 5cm wires to SWDIO, SWCLK and XRES. Voltages are stable (+/-20mV ripple).

Any idea why the PSoC can not be flashed while running with 5V?

Hello ! I am in trouble on programming cy8c4247 in a customer board. I have installed latest psoc3.2, psoc programmer and mini prog3 driver, but when i push the "program" button in psoc3.2, there are warning tips  "Warning: dbg.M0044: There was an error applying settings to the device.  The device may be in use by another application." and "Warning: dbg.M0039: There was an error running port acquire: Device can be acquired in SWD/JTAG mode only."  I come here for help, how can i fix this problem?
