What is the latest USB to I2C bridge software revision?

On the product I just purchased the "About" tab indicates version 1.25

The reason I'm asking, the user guide shows a function that it is not available on my version........specifically the ability to manually select the Y axis range on the "Variable Settings"  menu.

The attached files show the issue.

Thanks.

Hi:

I try to use EOC signal of ADC as trigger, but it failed. Then I put the EOC on output pin, and capture by Oscilloscope. EOC is hi instead of a pulse.

API ADC_1_IsEndConversion() polling indicates the convertion works well. EOC signal is hi, not toggled.

Can you help? Attached my schematic in experiment

Hello Everyone,

I am very new to the PSoC concept but I am very interested in growing my skills. My project goal is to develop a 20 channel function generator with an USB interface and then use an API/GUI to select the type of signals I would like on each of the 20 outputs. My requirements are such that the amplitude is in the range of 0-3 volts in 0.05 step and 0-20 Hz in 0.01 step (roughly 7 bit and 11 bit respectively). For the short term however my questions are:

1. Would I be able to meet such requirements with a PSoC 3?

2. Would there be much in external circuitry required?

3. Could I use internal amplifiers to adjust the amplitude i.e. gain control?

4. For now I would just like to get started with generating a square wave (not a PWM based design) on 20 of the PSoC3 pins so I can probe around with an Oscope as I explore how to use the hardware/software. I have the first touch PSoC3 starter kit. I am thinking I need  comparators/timers (20 of them actually) and just toggle the output with the count as 1/2 the period of the square wave. I do need to hold the resolution requirements for this. Not really clear how to get started on this. I watched some Cypress Videos and I have general navigation skills but I just need some help picking the right direction.

Guidance is highly appreciated.

Hi,

I am trying to get a 1KHz output from a PWM.  I am using a 8 bit PWM with the following configurations.

Clock - VC2 (VC1 divider = 16; VC2 divider = 15)

Period = 99

Pulsewidth = 50

With VC2 clock at 100KHz, with PWM period of 99, the output should be 1KHz.  But I am getting an output near 240KHz from the PWM.  Can someone point me what could be the mistake?

Can anyone explain explain to me how to set up a simple delay function? Is there a #include delay.h that goes up top?

I have the delay.h header file in my source code.

Is this the correct way to write the delay function?

if((PRT0DR & 0x02) == 0x02)

{

  PRT1DR = 0x01;

  Delay50uTimes(255);

  PRT1DR = ~0x01;

}

Any help would be greatly appreciated.

Thank you

What are the restrictions on the 8051 compiler that comes with PSoC Creator?

Hello,

My kit did not come with the 24 MHz crystal installed. Is there a reason that this is the case? Can I install a crystal myself, or is there an oscillator errata? 

Is there an option to use the mini prog 3 as debugger in the design challenge development kit?

If not, how do we use the debug feature?
