on the lcd slide. theres two spelling errors,

this line

vias voltage generation using dedicated DAC, and internal resistor leader

I think its supposed to be

bias voltage generation using dedicated DAC, and internal resistor ladder

next item

is this line

When I had a look at the schematics of the new -050 LP Development Kit I found a naming bug/typo.

The signals  from CY7C68013 DPLUS and DMINUS are named D- and D+ before connected to DP and DM of USB Mini.

Would be better to have that corrected.

hi happy users of this strange device

For students or schools, if you cannot afford the big kit, have a look at this.

I am measuring the change in a 300pF capacator. I have taked precautions to drive the shield with the feedback from my voltage follower. The capacator will change a maximum of 80pF for temperature and fumidity. For test pruproses I am using a 500hz clock through a series resistor(10m) through the 300 pF capacator. I am able to get very good RC curves. I have tried the camparator with and without clock sync.

After my comparator what is the best way to measure the pulse width time? I am trying to achieve 200 to 800 Hertz.

Thank You.

Hi,
i'm playing around with the ADC on the PSOC3, i've got the CY8CKIT-030. My Problem is even if i connect my input GPIO (P4.6) to VSSA, the rawvalue is very rough. It jumps around between bit 30 and bit 40, i expect a more stable value. Is it possible to get the noise smaller, so that it is stable on +-1 bit?
Sure a external voltage reference will help, i will try that, but isnt it possible to get more stability with the internal reference and without a filter?

I'm using:
-resolution: 16 Bit
-conversion mode: 2
-rate 2000sps
-input mode: single
-buffer gain: 1
-buffer mode: rail to rail
-Vref: internal bypassed on P0.3
-clock: internal

my code:

void main()
 {
Initial();

while(forever)
{
ADC_StartConvert();
ADC_IsEndConversion(ADC_WAIT_FOR_RESULT);
Rawdata = ADC_GetResult32();

sprintf(Buffer, "%ld", Rawdata);
UART_PutString (Buffer);
UART_PutCRLF(0x20);
}
}

so i get my rawdata displayed in my terminal.

Thanks

Hello! Chip used CY7C68034. Please tell me how to change the project CY3686FW, that it was possible to receive data from an external device (such as an audio codec or GPS receiver) and record them in memory NAND. Sorry for the translation.
