Hi,
I would like to know for family PSOC 1 the number of dac 's and resolution per chip.
In datasheet just states a something like "Up to 9-Bit DACs" but doesn't says clear wich device what characteristics has.
More than that some advertisements are telling that line Cy8C28 have better analog characteristics than Cy28C27 . I would like to see a comparation between them.

When using a bootloader to update main program from .hex file generated for psoc creator, how is the hardware(UDB) reprogrammed in PSoC 3/5? Sorry if this is a stupid question but where is the information on TRM about hardware programming for Universal Digital Blocks?

Hi All,
I'm having a problem on how to get I2C_bridge binding to the hub, i have tried to take the hex file from the correspondence firmware folder for RF_I2C_BRIDGE and program it to the RF_Bridge but i still can't bind the bridge to the PC_Hub.
Maybe the hex file i have is corrupted !!
However i have opened the RF_I2C_BRIDGE project that i have found in the CD, and whenever i try to build the project it show me the following error.
lib/cyfisnp_debug.c
process_begin: CreateProcess((null), cpsoc.exe --asmlist --errformat --chip=CY8C27443B --WARN=0 --mode=lite --OPT=asm,9 --pass1 --double=32 -q -I./lib -IC:/PROGRA~1/Cypress/Common/CY3E64~1/tools/include/CY8C27~1 -Olib/obj/cyfisnp_debug.p1 lib/cyfisnp_debug.c, ...) failed.
make (e=2): The system cannot find the file specified.
C:\PROGRA~1\Cypress\Common\CY3E64~1\tools\make: *** [lib/obj/cyfisnp_debug.p1] Error 2
RF_I2C_BRIDGE - 1 error(s) 0 warning(s) 23:09:31
Your help on solving this will be really appreciated !

I want to use the 8k ECC flash to store some user information. And from the data, it seems tha the user cannot program it directly, one has to program 32 byte at a time with the orgirnal row that extra 32 bytes is linked to.
My questions is
1. Is there a way to program the those ECC flash directly?
2. If it has to program with the row that it links with, does that mean we have to copy the first 256 byte from the row into the latch and then append the 32 bytes and do a write flash?
3. Is there a way to read more than 32 byte ie say 256 byte of the ECC flash in one go? Show Less

I need to use the cut-through USB/DMA mode in my design. Is there any example or more detailed appnote available?
Background: I want to use two 512 byte ISO endpoints. The maximum endpoint buffer in the PsoC 3 is in total 512 byte so i can only use a 256 byte endpoint buffer per endpoint. By using cut-through USB mode, the PSoC 3 will only keep part of the endpoint data in the endpoint buffer such that up to 1023 byte endpoint buffers can be simulated. As data is being sent to the host, more data is being DMAed from RAM to the endpoint buffer. Very nice but very little documentation available. Show Less

I have a CY8C24894 PSoC configured with CSDADC and I2CHW slave modules. The aim is to get the touch positions to an external processor via I2C.
For debug purposes I have commented out all the capsense code. When doing I2C echoes to the master processor without starting the CSDADC, I get a 100% success rate. But when the CSDADC module is started the I2C fails completely. Viewing the I2C lines on a scope shows that when it fails the PSoC does not even give an ACK to the master's address byte. The only difference between the working and non-working projects is the calling of function CSD_Start().
The selection option for CSDADC is "CSDADC with PWM8 clock source". I have attached the project. Show Less

Im a fourth year university student.
Im woking on my final project with some of your product then I got stuck with lots of problem
the components that Im using are cy3280-20x66( universial capsense contoller kit and Cy3280-SLM linear slider module kit.
here is my project overview.
it is about producing white LED with RGB mixing.
three LED (Red, Green and Blue), I want to control of each LEDs intensity with the Cy3280-SLM.
as u know there are 5 buttons and 1 slide. I want to set one button for Red, one for Green and one for Green. moreover
once each button has each different color I want to control the intensity with the linear slider.
So some questions are:
1. Is it technically possible with these kits (Cy-3280-SLM and Cy3280 20x66)
2. if it is possible what kind of sofeware program is needed to program?
3. something more component I need to purchase from your company?
4. anything I should know more?
I will be waiting your answer. Show Less

I have a system level capsense design with 10 buttons using CY8C20434. I2C hangs when inputs are configured as capsense. Using USBtoIIC windows utility it will sometimes list the device other times it will not. If it does it can take a minute or so to get picked up. Attempting to read button status the utility indicates that the I2C protocol is working but I may or may not read status change from a button. Sometimes the status will stick for a while before returning to zero.
I created an alternative sys level project with digital inputs on the same port pins. This works fine. It is only a problem when I am configured as capsense (CSA).
Have a previous design using CY8C20234 and 10 inputs, no problems.
The same product that has the 202434 and I2C problem has 6 other identical devices configured for two 10-segment sliders. These all work correctly.
What issue with button layout, shape, trace length, etc. might contribute to these symptoms. Seems to be only difference between my slider devices and this 10-button device.
Haven't received any response from my case for this, hope I may get something thru the forum.
