hello to everyone i want to develop oscillioscope and signal generator using psoc3 kit and want to display on my laptop using any program. i have very basic knowledge about psoc.Request to all forum member please help me to design this project
Show LessI'm trying to develop a system in which input data is decoded. The input waveform to be decoded is a spi byte from an external device with spi frequency of 100KHz this is connected to p1_3
The timer 16 is set to run at 1MHz with a period of 10, so that the terminal count occurs every 10us. P1_3 is set to generate an interrupt on every falling edge of the waveform
On the first falling edge the timer is started, on every subsequent falling edge the value newdip is updated. In the timer_isr, the program should check if there's been a gpio interrupt in the past 10us if not, the variable value[] is updated.
I tried running the program with only the gpio and only the timer16 and they work fine individually but I can't get them working together. I observed that only the gpio_isr is called not the timer_isr
Please can anyone help me? I've been stuck on this problem for a week now and still no solution. THANKS
Show LessHi,
I'm pretty new in programming and I have a Problem with reading out a Float Value from EEPROM.
To get the FloatValue in! the EEPROM i do this:
char *ptr = (char*) &FloatValue;
EEPROM_ByteWrite(*ptr++,0,0);
EEPROM_ByteWrite(*ptr++,1,0);
EEPROM_ByteWrite(*ptr++,2,0);
EEPROM_ByteWrite(*ptr++,3,0);
I think this works, but how can I get the value back?
Can you give me an example?
thanx
I have encounterd problem in SD card interfacing with SPI. Initialisation can not be done. EVen SCLK is not generating. Plz giv me some sugetns about what would be the problem.
Show LessHI fellow programmers,
I am doing some datapath and verilog programming and I needed help with the transferring of data. As you all know, all computation are stored inside the A0/A1 register. However, I am interested in pushing this data to D0/D1 register so that I can carry on with more computation on the A0/A1 registers. I have already used up the 4 bytes in FIFO. So is there anyway I can transfer the data from A0/A1 to D0/D1?
Show LessHi to all,
Can anybody help
How to design a simple waveform generator which can generate a sine, triangular or square waveform with a frequency of 400Hz based on the user function input e.g a switch.

Does CY8CKIT-001 Development kit support CY8C24423A-24PVXA Device?
Hi,
I should make composite usb device with USB HID and CDC.
I can make USB HID and CDC seperately. However, It's not easy to make composite device HID with CDC.
Application notes (AN58726; http://www.cypress.com/?rID=40103 pgae6,7 and Appendix 5) was somewhat helpful but I cant't understand what should I do.
especially I don't know ;
1. What is Interface Association Descriptor(IAD) and How I can write this, what is the rule.
2. and this application notes page7 says "There is also .inf file editing that is required to link the multiple interfaces to the CDC function. However, that will be covered in another application note or example project." I need information to edit .inf file.
help me please~
