PSoC™ 5, 3 & 1 Forum Discussions

Hi, 

I'm starting with development on PSOC and I'm interfacing a UART camera with CY8CKIT-059 and save the picture on a microSD, but when I try to save the picture I note that the function to write on the microSD is slow, cause not all data are writen on the SD. For example, the picture has a size of 25kb, but the file that I save has 10 kb. When I open the file on a hexadecimal editor I can see that lack many strings.

I add the code of the function, if is needed that I upload the project tell me.

---------------------------------------------

pFile = FS_FOpen(titulo, "w");
    Camara_PutArray(ReadPic,16);
    while(alar_idle==0){
        if(bufful==1){
            FS_FWrite(&buffrec[0],1,15,pFile);
            cont=0;
            bufful=0;
        }
    }
    FS_FWrite(&buffrec[0],1,cont,pFile);
    FS_FClose(pFile);

-------------------------------------------------

My UART buffer has a size of 15 bytes, and the baud of the camera is 38400 andhe frequency on the emFile is 4000 kHz. My alar_idle is a boolean that show me if the transmission has finished, cause when I tried check the last two bytes of the transmission the result not ever was appropriate. I've tried write with FS_Write, but it was worse.

I hope someone could help me.

---Updates--

-I've attached the project.
-Other problem that I had but I've solved making another routines was that I only could use the "strstr" function only once time. When start the system, but when I try to use it for take a picture, it not work.

Thanks

Hi all. I want to make a project with CY8CKIT-059. I want to receive sensor digital value from a photodiode using interrupt in digital pin. LCD will displays the value of sensor after interrupt works (interrupt will work when the light is OFF). After the counter value reaches 8, the processor will stop receiving data. Then, when I turn ON and OFF again the light, the processor will receive again the data until the counter value reaches 8. But, the reality is not like that. After the counter value is equal to 8, I try to turn light ON and OFF again, but the processor only receive 1 value from sensor and the counter doesn't work.

Here I also attached my project. 

Looking forward for your help. Thank you

Hello all, I need a little help.

I want an RTC with microsecond intervals, I'm using the  RTC module existing in PSOC 5 prototype Kit, and to generate the microseconds I am using a up counter  with a 1MHz in the input, my problem is how to reset the counter each one second interrupt of the RTC ?

I don't Know how to use RTC interrupts, I'd like to put this function "Counter_Init();" in the " RTC_EverySecondHandler(void)"

Thank you very much.

I am having trouble getting establishing UART serial communication between my PSoC 1 Eval Board, CY3210, with my PC. The specific device on the board is the CY8C29466-24PXI.

Basically, I need the PSoC to send data to my PC for a project, abut can't even get to the point of testing the UART connection. Right now, I am attempting to connect the 9-pin DSUB RS-232 port to a USB port on my PC via a standard RS-232 - USB cable. Upon connecting, my computer fails to install device driver software and stops the device due to it not working. I have installed the UART drivers from Cypress, and have attempted to associate them with the device, to no avail. Every time I manually tell my computer which driver to use, it tells me that the best driver is already installed and refuses to install the selected driver (cypressusbandbus.inf). 

If anyone has any idea how I should accomplish this, I would be very grateful for your help. Perhaps my approach of using the 9-pin is completely wrong. Please provide any suggestions that may help. Thank yo

Hi Guys,

Status = 0;
DMA_RSU_0_Chan = DMA_RSU_0_DmaInitialize(DMA_RSU_0_BYTES_PER_BURST, DMA_RSU_0_REQUEST_PER_BURST, HI16(DMA_RSU_0_SRC_BASE), HI16(DMA_RSU_0_DST_BASE));
DMA_RSU_0_TD[0] = CyDmaTdAllocate();
DMA_RSU_0_TD[1] = CyDmaTdAllocate();
CyDmaTdSetConfiguration(DMA_RSU_0_TD[0],2, DMA_RSU_0_TD[1], 0);
CyDmaTdSetConfiguration(DMA_RSU_0_TD[1], 1, DMA_RSU_0_TD[0],0);
CyDmaTdSetAddress(DMA_RSU_0_TD[0], LO16((uint32)&Array[0]), LO16((uint32)SPIM_RSU_0_TXDATA_PTR));
CyDmaTdSetAddress(DMA_RSU_0_TD[1], LO16((uint32)&Status), LO16((uint32)SPIM_RSU_0_TX_STATUS_MASK_PTR));
CyDmaChSetInitialTd(DMA_RSU_0_Chan, DMA_RSU_0_TD[0]);
CyDmaChEnable(DMA_RSU_0_Chan, 1);

PS: I have read all the documents/discussions related to PSoC, and SPIM but I am still struggling to work it out. I must be missing something here. Any help is appreciated.

Hi,

Can the PSoC be put in sleep or hibernate mode and still keep the mux routing active?
If yes, how much would this affect the power consumption?

Kind regards,

Niels

Hello, 

I am trying to sample 12 ADC channels and 8 I2C sensors at specific time periods. The timing is like this: 

A - 10ms - ADC 0, 1, 2

B - 50ms - I2C 0, 1, 2, 3

C - 100ms - ADC 3,4,5,6,7

D - 1000ms - ADC 8,9,10,11 and I2C 4,5,6,7

I am using a 12ch MUX, DelSig ADC, I2C bloc and for the specific timing generation multiple Frequency Dividers from the 1Khz ILO clock. 

The two ways I tried were: either read in each ISR all the relevant sensors  OR  set flags and execute in main using IFs ( if(ISR_flagSet -> read sensors)

Both are suboptimal solutions as the execution time varies, A is much faster than C and they don't work very well. An ideas are more than welcome. I need to read the sensors at fixed time to be able to integrate and differentiate them. 

I'm not sure this is possible using a single core MCU.
