PSoC™ 5, 3 & 1 Forum Discussions

I have the CY3210-devel kit. It comes with an LCD module, that is by Hitachi (HD44780).

My project is working with 3.3v Vdd and the LCD won't print.

I checked the LCD's datacheet and it says there that it can work on a 3.3v Vdd.

How can I make it work on 3.3v??

Hi all,

I am stuck with a problem with the ADC14.

When the PSOC gets warm, the reading of the ADC14 suddenly drops down a significant number and stays down until the chip has cooled down again. I have a simple PT1000 with a resistor attached to the input, nothing should happen there. The voltage should be stable at 5.00V.

I could prove this several times by heating the PSOC with hot air and cooling it down again.

I am talking about a start temperature of 20 degrees centigrade (normal room temperature) and a top temperature of 50 degrees centigrade (not too hot). The jump happens at around 40 degrees centigrade.

Until now I can not exclude that there is another design problem on my board, but I think this may be a problem with the ADC or its settings.

Could you please let me know what problem I might have run into?

Best regards,

Turtle

 G'day all,

I've sorted out the debug connections for my design thanks to the support guys here, but now I'm having a different problem.

I can't seem to find a supplier for the 10-pin debug header as used on the development kit's PSoC3/5 modules.

This is a 10-pin 0.05" dual in-line IDC-style receptacle. In the parts list, it's listed as Digilent 161-026, but that company doesn't seem to have or handle individual connectors. Instead, DigilentInc is a system board (FPGA) design business. They appear to neither stock nor sell individual bits and pieces.

None of the "big" suppliers (Farnell, Digikey, Jameco, Mouser, etc) stock this particular part. At least, not shrouded, which would be the most suitable. I can find various male PCB connectors, but I'd really like to have a polarised connection, as this design will be used by students and hobbyists, and I want to make it as bullet-proof as possible.

As I'm based in Australia, I'd much prefer to deal with a vendor who has an online presence.

So my question is, could anyone provide details on a suitable connector that will allow the Miniprog-3's cable to be directly connected for debugging and programming? Preferably something they know works with the connectors supplied with the Miniprog-3.

Otherwise, I'll keep looking, and if I can find a replacement, I'll post details here.

Sorry for asking such a silly question here.

Regards,

PCPete

 Does anyone have a lead on the SAMTEC connectors used on the PSoC modules?  SAMTEC has given me a lead time of 16 days to make the connectors. I may just rip them off of the dev kit unless someone knows where I can buy them.  As this is currently the only method of interfacing with the PSoC aside from the dev kit it seems strange that they be so hard to find.\

Thanks,

Hi,

I search a Sample Firmware Source Code for module "Graphic LCD Interface (GraphicLCDIntf)".

I seem to be in "CY8CKIT-032 Graphics LCD Interface Kit", but I can find it on web.

Thanks a lot

I wanna use LCD of Psoc3 to display somes datas such as 17.3 , 56.7 .......

is there any functions for this ?

Hey all

I'm using the Psoc 5 and have instantiated the UART module v1.20. I noticed that after a call to USART_Start() i have to wait a bit before I can use PutChar or PutString. A delay of even just 1ms is enough, If no delay is present the first few characters are dropped. Any idea what's going on?
