PSoC™ 5, 3 & 1 Forum Discussions

After adding an OPAMP to the design, it is assigned as OPAMP_1 but I can't tell which one out of the 4 devices available [0:3]. I need to be able to instantiate a specific Opamp, i.e. Opamp_0 as I need to use GPIO0[1] for the opamp output. I have studied the datasheet and AppNote but they never mentioned about this. Please help.

Thanks,

Brian

Hello

I'm looking for the easiest way of using PSoC5 to make a:

* 3 identical squared signals, shifted 120 degrees (It could change to be a SPWM sinus signal, but for now, a PWM could be enough)

* About 5 KHz, 20% tunnable by program, (depending on an audible feedbak captured with a microphone)

* Able to read 3 I2c, 2 ADC with low resolution, the audio, and act as programmed

* Handling an LCD Display

* With an interruptions clock to know each round of program if tasks, as the LCD, are ready, instead of being waiting for their answer to can continue attending the generation of signals

My real problem has been to know  how to generate this 3 signals, so If solving the generation of them, the rest can go further easily.

Hello,

My host is connected to a PSOC that contains a USBUART. 

Upon PSOC boot completion, the PC has a new COM23. 

On the PSOC side I used the following code to initialize:

USBUART_1_Start(USBFS_DEVICE, USBUART_1_5V_OPERATION);    
while(USBUART_1_GetConfiguration() ==0);
USBUART_1_CDC_Init();

On the PC, COM23 is configured to 115200[baud], 8 (data bits), 1(stop bit). 

I succeeded to send a packet to the PSOC and get a reply from the PSOC. 

But it seems the rate is quite low. 

Example: I sent 28 bytes to the PSOC and got 36 bytes from PSOC. 
Expected: (28 + 36) * 8 = 64 bytes = 512 bits
The time required to send + receive should be: ~4.5msec
Actual: The elapsed time till I got a reply was much longer. 

Is it possible to improve the performance ?

Thank you,

Dear All:

There is a I2C mater and several slaves with the same address so I need a mux to determine which slave device i want to control. And i use analog mux in the CY8CKIT-059 kit to implement  my purpose.

p1[2] is SDAT source signal from master

p3[1] is connected to SDAT0 of slave device_0

p3[4] is connected to SDAT1 of slave device_1

as attached p1 shows.

and then I found it didn't work. So i took a measurement using scop as attached p2 shows.

channl4(green color) is clock from master

ch1(yellow) is measured by p1[2]

ch2(blue) is measured by  p3[1] .

ch1 and ch2 should get the same signal when using analog mux as their connection bridge, but they don't.

how do i solve the issue?

Thank you.

by the way, all of my pins' type setting is "analog", drive mode is "high impedance analog". 

While programming the debugged code, message shows

"There was an error while programming the device: PSoC Programmer reported error (100 - PSoC Device (1E 02 80 69) is not in the DataBase)"

kindly suggest way out to update the data base

Hello,

Is is possible to monitor a shutdown in PSOC 5 ?

Currently I read several VMON voltages. 

How can I know exactly when PSOC 5 is shutting down ?

Thank you,
