hi friends, i was making a simple keycheck program, i selected the pins(p1.0, p1.2, p1.4, p1.6), where i connect push-buttonsand made them in pull-up mode so that on pressing the key, ground makes the pins active.
But on selecting all these 4 pins to pull-up mode, i realised that only p1.0 was initally pulled up but no other pin was pulled up , though i selected all the 4 pins to be in pull-up mode.
I need help, as i need 4 buttons to run my project, so whats the probllem with this, or is there any other solution to it.
my program:
_main:
mov REG[PRT1DR], 255
keypad:
TST REG[PRT1DR], %00000001
jnz nextkey
call tx_front
nextkey:
TST REG[PRT1DR], %00000100
jnz nextkey1
call tx_back
nextkey1:
TST REG[PRT1DR], %00010000
jnz nextkey2
call tx_left
nextkey2:
TST REG[PRT1DR], %01000000
jnz keypad
call tx_right
jmp keypad
Show LessThanks about the Enoa parameter. The datasheets states:
ENOA Noise at 1 kHz (Power = Medium, Opamp Bias = High) – 100 – nV/rt-Hz
But anyway, I introduce a sinusoid into a PGA follower (Gain=1) and apart I monitories the input and output in the First column and I get the image 1, obtaining the expected.
Input=Output (Port 0_3)
(Vsin input= 500Hz 1Vpp and 1Voffset)
When I did the same in the second row I got a noisy sinusoid output. The output is equal to the input but the noise is much higher than the specifications told in the datasheet, so I still thinking my part is damaged.
Image 3 shows the add noise is around 800KHz and 1MHz.
What do you think about it?
Is damaged my part?
By the way, I have a RC filter in my Port 0_5 board outout.
Could it produce the noise?
Show LessI am trying to interface gsm modem to psoc. my problem is that i am sending AT command to system through UART ar baud rate of 4800. i am sending ok from hyperterminal manually. it is getting displayed on the lcd. but when i am doing same thing with gsm modem i am unable to get the result. one more doubt when i am testing gsm modem with system i am typing AT and after that "enter" key then i am getting response "ok". now how can i send "enter" key function to the gsm from psoc device?
Thanks & Regards

Show LessI have a programmed CY8C27443-24PI that I wish to use as a "master" from which I can program others. Can I do this with the PSoC ISSP or any other devices Cypress offers?
Show LessHi
My customer using cypress USB console to do the programming at the functional tester. I would like to understand more on this software. What is the name of this software and where can i download the software?
Thanks.
Show Lesswho can help me ? what is the problem?
I've just purchased CY8CKIT-003.
The example proximity project seems to be from another hardware. As I'm studing schematics I can't see any cmod cap, or rb
(feedback resitior) available. But this how project was preconfigured.
Secondly sensor is saturating at any settings. Unlike with PSOC 1 examples I see no clue how to trace the problem further, cause the capsense is totaly redesigned in API)
Please sugest any hint how to step further.
Thanks

Show LessHi,
I want to CapSensing for Liquid Level Sensing in my project. I guess there supposed to be an Application Note for this which i am unable to find. Is it possible to use Capsense for Level sensing?? if yes, please guide me.
Thanks & Regards,

Show LessDoes anyone know solution to this problem. I aware it's "spaces not recognized in directory naming" kind.
but in cyp3isrpatcher.exe arguments path there is no 'C:\program'
C:\Program Files\Cypress\PSoC Creator\1.0\PSoC Creator\bin\cyp3isrpatcher.exe "E:/Desktop/Project3-Reentrancy example.cydsn/DP8051-Keil_Generic/Debug/Project3-Reentrancy example.omf"
The application 'C:\Program' could not be started. Error: '%1 is not a valid Win32 application.

The command 'C:\Program Files\Cypress\PSoC Creator\1.0\PSoC Creator\bin\cyp3isrpatcher.exe' failed with exit code '2147483650'.
