Hi folks,
I am currently working on a touch application which should use absolute coordinates.
How can I change the relative coordinates into absolute coordinates in USBFS?
I have read through the datasheet component but it either doesn't say or I've missed it.
Thanks
Hi, i'm having a first time play with the bootloader on PSoC 4 - loving it, fantastically easy.
Only issue i'm experiencing is that after successfully programming the new firmware over UART (via bootloader host), the new application doesn't start automatically and i have to perform a manual reset.
Is there something i'm missing?
kind regards,
Damian
What is the CPU speed in PSoC 4200 devices. Is it 48MHz or 24MHz?
Is there a default prescaler to slow down the speed or does it run at maximum speed by default?
Thank you
What happens if the CPU tries to read ADC data while the ADC is writing the results to the channel register? Is there a possibility of error that needs to be handled by the programmer or does the ADC_GetResult16() function handle it itself?
Thank you
Hi.
As I understand, the use of Bootloader component is with a Host only.
Is it possible to make some kind of custom bootloader, which reads an image from an external memory? Is there an example maybe?
Thanks.
hi guys
i found that in this file
http://www.cypress.com/file/140991/download
page no.3 2.2 System Power Modes says SCB(i2c/spi only) is available in deep sleep mode
i don't understand what "available" means
meaning you can set i2c/spi to read or write in deep sleep mode ?
or meaning just system can wake-up from i2c/spi events ?
thanks.
How do you clear this error:
Error: flash row: 254 is either already used or does not exist.
The command 'cyelftool.exe' failed with exit code '1'.
Can you objdump the elf file and find how much memory is available. My resource meter shows memory as 99.9% full.

Hi,
I would like to use the PSoC 4100S-Family. But I have some requirements acc. the ADC Module
- sample and conversion time: min. 7µs
- external reference voltage input for ADC
switches between 1.3V and 2.5V
no internal connection to VDDA
- differential ADC measuring
1 channel
programmable gain amplifier (gain: 4)
down to -0.7V input voltage at one input pins
My question is, how can I measured down to the - 0,7 V on the ADC input? Is it possible?

if i want to make universal thermocouple sensing device than is that thermocouple component do that??
because i believe there is no API for change thermocouple type in run time application.
Hi,
I have looked through some similar threads but I haven't come to a solution so far.
I am using a custom PSOC4248AZI-L485 Board and I cannot launch the tuner.
I have configured the EZI2C according to the settings using the pins P3_0/P3_1 , but when using the MiniProg3 the connection always fails.
Any clue what I am doing wrong?
Programming the device works fine.
AN86526 refers to the communcation_api.c and .h files. I assumed this would be in the cybootutils along with the others, but I don't see it there.
Does anyone know the location of these files? I see the struct pointers to the four functions in cybtldr_api.h but that's it.
Hello Experts!
I have been using the kit CY8CKIT-049 for quite some time now and have delivered a few successful tasks.
However, there has been a problem with the kits that they can not be acquired by MiniProg3.
I have 7 such kits now - 3 of them just out of the pack - that can not be recognized by MiniProg3 - with Creator and with Programmer.
The MiniProg3 seems Ok because I can still program some older kits.
This is now a real problem, and any help would be highly appreciated
Thanks!

This seems like something I should be able to find, yet I keep coming up empty. What input current does a PSoC 4 GPIO pin use when configured as a high-impedance digital input? (And, why can't I find this in the datasheets?)
In our production code we'd like to have have the exception handler cause a reset.
Is the correct way to do this define this callback? Where should this define and the callback function be handled?
#ifdef CY_BOOT_INT_DEFAULT_HANDLER_EXCEPTION_ENTRY_CALLBACK
CyBoot_IntDefaultHandler_Exception_EntryCallback();
#endif /* CY_BOOT_INT_DEFAULT_HANDLER_EXCEPTION_ENTRY_CALLBACK */
Hi All
I am working in a direction to decide the values of the pull up resistors for I2C on PSoC4. I am running the CY8CKIT-049 from USB of my Laptop so it is working on 5V. I kindly request you all to give me guidelines to accomplish this.
Thanks in advance.

Hello all,
I was working with CY8CKIT-049-41xx PSoC4 Prototyping kit.
I get this error (when trying to program through Bootloader Host):
10:32:18 AM - Selected device: USB Serial Port (COM4) - UART
Generic Serial Port
10:32:29 AM - program Started
10:32:30 AM - The operation has timed out.
10:32:30 AM - Communication port reported error 'Unable to read data from the target device'.
10:32:30 AM - program failed in 1010 ms.
Any ideas?

Hi
I am toggling a pin continuously with Delay between toggling around 1us using the function CyDelayUs.
Is there a way to toggle the ping faster than 1us? or in other words how do I create a delay less than 1us?
regards
I get this error for one PSoC while using bootloader host, but can down load the identical code to a second PSoC with no problems.
Here are my relevant sections in the PROJECT.elf file showing text, eh_frame and rodata, do not overlap with cyloadablemeta. 0x7BF0 vs 7FCO.

Hello guys,
I'm using the ADC SAR Seq on my PSOC 4100 series to detect a high current. I want the interrupt to trigger when the ADC senses a voltage above its limit. I don't want the interrupt to continuously trigger to check the ADC registers(which it's currently doing). Below is the interrupt routine:
CY_ISR(ADC_LIMIT_ISR){
uint32 intr_status;
intr_status = ADC1_SAR_INTR_MASKED_REG;
windowFlag = ADC1_SAR_RANGE_INTR_MASKED_REG; // Read range interrupt status and raise the flag (High Limit)
if (windowFlag){
ADCMode = 1;
OutputsOFF();
}
ADC1_SAR_RANGE_INTR_REG = windowFlag; // Clear range detect status
ADC1_SAR_INTR_REG = intr_status; // Clear handled interrupt
}
Thanks,
Rick
Hello PSoC Community,
I have issue with reading the value using characterstic UUID, when I try to read I am getting an error Attribute Handle not found.
If anyone know what is the event handler for the READ USING CHARACTERISTIC UUID, please let me know.
Thanks
