Using  PSoC Creator 4.2 for  the PSoC 5. I am monitoring a thermoelectric cooler (TEC) controller that reports both positive and negative currents and voltages.  As long as everything is positive I'm ok. I'm taking an ascii string representation of hex numbers and converting it to a long that is stored in a uint32. If I get a negative number and apply the following, I always get 0x7FFFFFFF.

h2 is a global uint32 (hex 2 byte)

h2 = strtol(cbuf, (char**)NULL, 16); // create the uint32 from the payload

I'm sure there is an easy way to do this without having to write a bunch of low level code to sort the sign bit, exponent and mantissa.  Should I cast h2 as float  and use atof to convert it? Somebody has surely done this.

Thank you,

Nick

Hi all.

I have a project with BLE v3.66 component built in and I would like to update it to v4.2.

I used automatic update component and the .cysch file already shows the Bluetooth Smart 4.2 symbol.

Is there a way to automatically go from 3.66 to 4.2?

Thanks,

Best regards.

We are using CY7C53150 Neuron chip, the external flash memory used is AT29C512. But this 29C type of flash memory is EOL and no more replacement can be found in market. Can someone advise what is the alternative external flash memory I can use? I have identified SST39SF010A, but this chip does not appear in the supported flash list of CY7C53150. In fact, only 29Cxxxx is supported. 

I programed SST39SF010A with the same image loaded in orginal AT29C512, but the program does not load into CY7C53150 as expected. Please help to suggest an alternative part to AT29C512. Thanks!  

I am developing a FlexRay communication board.
I am using your communication chip.
Can I get sample code for CY88121C FlexRay controller?

Thank you.

Hi,

I am currently working in a project based on CX3. We have developed both an own hardware which embedded it, and a host application.

Our product works as a bridge between MIPI and USB protocols, in order to drive the pixel information from a CMOS Image Sensor to a host.
A complex softwere layer, inside the host, will run after it applying image processing algorithms.

After this overview, I want to explain my doubt. I have been working in both hardware and firmware layers, for this reason I have EZ-USB Suit
installed in my laptop, because I use it to complile the firmware image, which it will be store inside the embedded SPI-Flash memory in the PCB. So, as I have installed the EZ-USB Suite, my laptop has the cypress custom driver which achieve recognize the CX3 as Cypress USB BootLoader. Finally I store the firmware in our hardware design via Control Center tool.

But We need to update the firmware image in whatever laptor, including all of them which do not have the EZ-USB Suite installed. For this reason I would like to know which are the minimum necessary files (contemplated in the SDK EZ-USB Suite) that We need to add in our software layer in order to be able to upload the firmware, discarding the rest of the files of the SDK EZ-USB Suite.

Thanks so much.

Dears. 

Would you recommend programming kit for CY3672, CY3675A or CY22381 ?

If Cypress' programming kit due to the fact that is obsolete is phased out, please give me your recommended  any brand 's programming kit  which can support these items. 

Thanks and regards,

I want to send String data using uart and receive string data using uart on cy8c4245axi-483. I want sample code for doing this.

Please Help,

FreeRTOS and TCPWM blocks are not working together.

Steps to reproduce:

- Create the AnyCloud_TCP_Client example using the Modus Application creator dialog.

- Create a PWM block using the Device Configurator and call it PWM1 (I used Block 23, Pin10[2] but have tried others too).

- Before the xTaskCreate and vTaskStartScheduler in main(), start the PWM1 block with

    printf("============================================================\n");
    printf("CE229112 - AnyCloud Example: TCP Client\n");
    printf("============================================================\n\n")
    //////////////////////////////////////
    Cy_TCPWM_PWM_Init(PWM1_HW, PWM1_NUM, &PWM1_config);
    Cy_TCPWM_PWM_Enable(PWM1_HW, PWM1_NUM);
    Cy_TCPWM_TriggerReloadOrIndex(PWM1_HW, PWM1_MASK);
    Cy_TCPWM_TriggerStart(PWM1_HW, PWM1_MASK);
    CyDelay(1000);
    ///////////////////////////////////
    /* Create the tasks. */
    xTaskCreate(tcp_client_task, "Network task", TCP_CLIENT_TASK_STACK_SIZE, NULL, 
                TCP_CLIENT_TASK_PRIORITY, NULL);

    /* Start the FreeRTOS scheduler. */
    vTaskStartScheduler();

- Upload Code to PSoC6 PROTO 2MB

Result: Square wave appears for 1 second, then disappears.

Expected behavior: Square wave appears and stays forever.

I've also tried moving the PWM Init/Enable/Start code into the RTOS task (tcp_client_task) but doing that results in no square wave at all.

Why is FreeRTOS preventing TCPWM from working properly and how can I fix it? Thank you for you help.
