PSoC™ 5, 3 & 1 Forum Discussions

The datasheet says that the comparators may be preceded by a low pass filter.  A low pass filter appears on the analogue routing diagram.  The lime green is my addition.  It's greyed-out.

There is no LPF in the comparator config and there isn't a LPF in the component catalogue.

How do I get my mitts on this component?  It seems tantalisingly out of reach.

I bet I'm doing something silly.

Hi,

i am trying to connect one SAR ADC to a two channel filter. i expect to filter each sample on both filters simultaneously.

i tried to follow ADC to Filter –Dual Channel 16-Bit Streamingusing DMA–PSoC® 3 / PSoC 5  EP58353

but i don't see any ADC nrq. first i attempted to implement ADC to SRAM and that word fine.

please help me to configure every thing.

Thanks

Hello,

I am using a time-stamp method of measuring a frequency of a signal. The signal is a square wave, and causes a DMA transfer to start when a rising edge is detected. There is a circular RAM buffer that holds the timestamps / counts of the timer each time the input signal has a rising edge.  A function is called periodically to subtract the counts from each other to estimate the frequency.

I used the example project from the CONSULTRON which is posted here:

https://community.cypress.com/t5/Code-Examples/Multi-Input-Frequency-Measurement-Tutorial/m-p/183038

Everything works as expected when I use the "Fixed Function" timer block with 16-bits. However, when I try changing it to a 24 or 32-bit UDB timer block, the counts do not make sense. The least-significant-byte of the RAM buffer always has the same value for some reason. When I look at the debug window for the component, the count matches what is expected in the MEMORY viewer, but it seems like the value at that address is not being transferred via DMA? 

I referenced AN61102 which shows how to transfer 32-bit values from 16-bit spokes. I added another DMA channel as an intermediate step, and from the intermediate step goes to the larger buffer.

I was using the following #define in the DMA configuration to retrieve the counts, which is 0x4000_6508: Timer_Count_COUNTER_LSB_PTR_8BIT

Hello.

Customer used CY8C5868LTI-LP039.

And they used EEPROM and DieTemp components.

When die temperature measurement is started, writing to EEPROM becomes fail.

If DieTemp_1_Start () is not called, EEPROM_1_Write () will succeed.

But EEPROM_1_Write () will fail if there is DieTemp_1_Start ().

Error status is CYRET_UNKNOWN.

Why is EEPROM_1_Write () an error?

And could you please let us know a method that EEPROM_1_Write () will succeed even if there is DieTemp_1_Start ().

Best Regards.

Hello,

Are there any restrictions in using DMA configuration registers (of another channel or maybe even of the same channel but another td) as destination for a DMA transfer?

I want to modify the configuration of a DMA channel (source and destination settings in td's especially) on the fly, not done by software but by (another) DMA channel, of course not during ongoing request using this data.

Devices I use are of 54xx, 56xx and 58xx series.

Thanks.

Hi,

Can we just implement TPS25982 block diagram to PSoC5LP MCU. I am attaching the link for datasheet of TPS25982 and the functional block diagram

Please do let me know in full brief about the different blocks.
