PSoC™ 5, 3 & 1 Forum Discussions

Dear all,

I am working with PSoC5 Family 55 (right now with KIT 050). For propagation of error calculation I need some values of the Delta-Sigma ADC.

Unfortunalty in the Datasheet the values are not given, or only given for 16 Bit (for instance.)

I am using the ADC with the following configuration: single ended, 17 Bit 11830 sps, internal reference 1.024V * 2 (internal bypassed), Buffergain 1, Levelshift.

For this configuration I need to know SINAD, RMS Noise and RMS Amplitude to calculate noiseless resolution and effective resolution.

Somebody can help me with that? Is there an extended datasheet of the Delta-Sigma ADC? 

Thanks a lot in advance,

Thomas

 Is it feasable to use a capsense button as a power on button?

I'm designing a PSoC application which would spend most of its

time in sleep mode, but would be woken from sleep by a button.

Obviously the capsense doesn't work in sleep mode, but is it possible to

wake it up, say, every 100ms and test the buttons? If the 'on' button

detects a finger, then the device would come into full wakefulness, and

stay awake.

 Hi,

I want to use the ECC Flash space to save user data and dispose of 8KB extra Flash. To do this, I go to the System tab in Psoc Creator, and dissable the tick of Enable Error Correcting Code (ECC).

Therefore, It's supposed that now I have 64KB+8KB = 72KB of Flash, am I right?

Well, why when I program the device appears the typical message in green letters (showed below) and the Flash avaliable seems to be 64KB instead of 72KB? Thanks.

Flash used: 3679 of 65536 bytes (5.6 %).

SRAM used: 85 of 8192 bytes (1.0 %).

Hi, Does anyone know if there are any driver for wireless communications with PSoC5 (CyFi :CYRF6936  CYRF7936) ?

Hello,

My project consists in programming the PSoC as a signal adquisitor using the different types of ADCs in order to see the differences between them.

Now I am trying to use the SAR6 ADC but I don't fully understand how it works when it get the samples.

When I read the datasheet and the API functions I understand that the sample is taken when I call the SAR6_cGetSample(), and it takes some microseconds to convert the sample. Then, how does the Analog Column Clock influence in the Sample Rate? It seems that the Sample Rate would be related to the code where I have the SAR6_cGetSample() function instead of the Analog Column Clock.

Another doubt is why some tables of the datasheet say that the Conversion Time is 20 microseconds with the condition of a CPU of 12 MHz and fclock of 250 kHz, if then the datasheet says that this time is six times the period of the sample clock. Is it a variable parameter or not?

And finally, understanding that fclock mentioned in the tables of the datasheet is the same as sample clock (phi1 and phi2), why is it limited to 333 kHz if it depends on the Analog Column Clock? It would be some MHz, couldn't it?

What I am misunderstanding?

Thank you,

 Hi,i am new with the psoc 1. I want to use Timer8.But there is no enough example on Datasheet.

For my project,when every data block gets by UART,the LED should be ON for 1 ms.How can i do this?I  searched the forums and I used the examples.But i couldn't use Timer8 module..

Hi everyone,

I need to transfer a struct variable composed of two fields (uint8,uint16) towards an SPI interface.

I tried to use a DMA channel and only one TD, configured to transfer 1 byte per burst with increment of the source address.

With this configuration, if I set the struct variable as: (0x0F,0xFFFF) I see on the oscilloscope: 0x0F,0X00FF.

Even using 3 byte per burst the result is the same.

Is it needed to use a dedicate TD for each field of the Struct variable or I need to configure the DMA channel and the TD in a different way ?

Thanks in advance
