PSoC™ 5, 3 & 1 Forum Discussions

 I am facing problem with receiving multiple data bytes. I don't know whether the way i have implemented is correct or not.

I  have enabled interrupt of SPIs as interrupt on RX_FIFO_NOT_EMPTY.

In the isr i read the no of. bytes received SPIS_ReadRxBufferSize and display the values on LCD directly.

Initially i had set buffer size of 4 and hence i was just able to get only 1 byte of data even on sending 3 bytes as no. of bytes SPIS_ReadRxBuffer was returning only 1(even datasheet says it provides 1).

So I changed to more than 4 bytes buffer. But still i am unable to receive the bytes.

Any solutions ??

 I image could not create the firmware in psoс desinher in assembler for flashing LEDs. If someone has an example project with pictures or video tutorial on creating projects please please I will be very grateful. Excuse me please either something is not clear I from Ukraine and difficult for me to correspond to the English

So I read the application note regard peak detection on the PSoC (AN60321) and the Peak and Hold method is exactly what I am looking for, only problem is I can't get it to work at a frequency faster then 4 MHz which it says is due to the mixer being used (The LO cannot exceed 4 MHz). I am trying to measure the peak voltage of a pulse that is about 3 microseconds in duration so I get about 12 samples per pulse (3 microseconds/250 nanoseconds).

Is there any way to get around the 4 MHz macimum LO, or is there an altogether better way to detect peaks at higher frequencies?

Hello,

are you planning to start new Design Challenge?

Hi Everyone,

I got an error that has me stuck. My attachment shows the error pop up and my note explains how I got there.

Any help would be appreciated. Thanks TDGM

Whenever I call USBUART_Stop() even before starting the USB UART component that is USBUART _Start() the , I am seeing that the component doesn't even work.

I noticed that USBUART _CLK_Enable bit doesn't get set even if it is assigned 1.

You can reproduce this issue by opening the simple USBUART example project that comes with the creator and just call USBUART _Stop() before calling USBUART _Start() and then you can see thyat USBUART_Clk_Enable bit not set and also enumeration doesn't happen .

Can you tell me what goes wrong if i call Stop before even starting the component.
