PSoC™ 4 Forum Discussions

Hello,
New to PSoC, just testing different components to see if PSoC fit our needs.
One of the tasks is to communicate with a Master over RS485 using MODBUS protocol. Baudrate is 921600.
Master send a request packet to Slave (PSoC) twice every second and expect updated values as reply.
Master request send 0x02, 0x04, 0x01, 0x13.
After some testing I've concluded that PSoC save the bytes in wrong order:0x04, 0x01, 0x13, 0x02.
That is so weird that it took some time to even believe.
Tried to read documents, examples and forum posts without finding a reason for this to happen.

Missing something essential?
We're using CY8CKIT-043.
I'll attach minimal bundle .zip file.

while i am adding debug .h and .c file in my UART project and getting below error .

Build error: The command 'arm-none-eabi-gcc.exe' failed with exit code '1'.

i want to use DBG_PRINTF(" "); function for that i had include debug.h and debug.c  now it showing me (Build error: undefined reference to `DBG_PRINTF') error .

Hi,

I have some dubts about the Proc.

what I do with the pins not used the EZ-PROC? How do I set to prevent the leakage current.

Leds can connect directly to the pins of the EZ-PROC? He can provide necessary current to light LEDs? If so, which pins can I use?

Thank you!

Hi everyone,

I'm trying to get the Bootloader over the air running with my CYBLE-022001-00.

Now I realized that my normal application (without the bootloadable-component) already uses 94.4% of the available Ram.

I guess this is why I'm getting errors when i put the bootloadable component in and try to compile.

My question now is pretty basic, so I don't know exactly if this is the right forum, but I post it anyway:

Can someone tell me where in my project I use all the ram??

My project is still pretty small (ok, it uses the BLE-component, but this chip is made for this...), so I'm wondering how anyone would ever build a bootloadable application if this doesn't fit.

Or maybe someone can tell me another error in my thinking, because i need this application to be bootloadable.

I would really appreciate the help.

Best regards,

Gregor

Updating component Cy_boot 4.1 to Cy_boot 4.2 (PSoC Creator 3.3) causes gcc printf to fall into an interrupt unhandled trap;

I tried component CY_Boot 5.2 and the problem is still there. It works fine with component Cy_boot 4.1. 

What is the new procedure to use gcc printf ?

I'm referencing the Dynamic Broadcaster and Battery Level examples from 100 Days, and wanted to work on a switch that would interrupt, computer the battery percentage, update the advertisement info, and restart broadcasting.  Using the module only, and not the dev kit, if pin 3[7] were my ADC pin, would I just 'jump' that pin to VDDR?  Do I need a 1uF cap of anything?

Hello all, Please have a look at this function in a Proximity Sensing regards:

/***** Function Name: Output_Init  *********

* Summary:                 *  Output_Init() performs following functions:

*  1: Starts PRSm        * Parameters:   *  None.               * Return:             *  None***/

void Output_Init(void)

{       

          /* Set up WDT to generate the wakeup/timing ISR */

          /* Update the match register for generating a periodic WDT ISR. */

          /*Note: In order to do a periodic ISR using WDT, Match value needs to be

                          updated every WDT ISR with the desired time value added on top of the

                          existing match value */

          #if ((0u != CapSense_IS_M0S8PERI_BLOCK) && (0u == (CY_PSOC4_4100BL || CY_PSOC4_4200BL || CY_PSOC4_4100M || CY_PSOC4_4200M)))

              CySysWdtWriteMatch(WATCHDOG_TIMER_COUNT);

          #else

                          CySysWdtWriteMatch(0, WATCHDOG_TIMER_COUNT);

          #endif /* (0u != CapSense_IS_M0S8PERI_BLOCK) */

          #if ((0u != CapSense_IS_M0S8PERI_BLOCK) && (0u == (CY_PSOC4_4100BL || CY_PSOC4_4200BL || CY_PSOC4_4100M || CY_PSOC4_4200M)))

                          /* Enable the WDT interrupt in SRSS INTR mask register */

                          CySysWdtUnmaskInterrupt();

          #else

                          CySysWdtClearInterrupt(0);

          #endif /* (0u != CapSense_IS_M0S8PERI_BLOCK) */

          /* Map the WatchDog_ISR vector to the WDT_ISR */

          WDT_ISR_StartEx(WatchDog_ISR);

          /* Start PRSm block */

          PRSm_Init();

        PRSm_WriteCounter(LED_OFF_DUTY);

          PRSm_Enable();

}

Please explain the meaning of following lines:

#if ((0u != CapSense_IS_M0S8PERI_BLOCK) && (0u == (CY_PSOC4_4100BL || CY_PSOC4_4200BL || CY_PSOC4_4100M || CY_PSOC4_4200M)))

Thanks & Regards-
