PSoC™ 5, 3 & 1 Forum Discussions

I input a 6bits_code_min=0dec or 6b_code_max=62dec value into the DAC6 by means WriteStall API and I get unexpected Voutput value.

Theoretically the DAC6 datasheets told us:

Vout=(Vrefhi-AGND)*ACap/FCap+AGND

Taking into account my reference Vdd/2+/-BandGap I must to have:

Vout(max)=3.76V

Vout(min)=2.5V

Instead of this I obtain a more or less a  Vout=3.7 V  and after that the value is going down until reach

aproximattely 2.5V. I put the analog outputs in High Z.

The C code is simple:

"PSoCAPI.h" // PSoC API definitions for all User Modules

#define

} /*main*/

Anyone could tell me what's going on?  Thanks

 Hi ,

   can anyone plz send me a ready to use seven segment display routine......or project for CY8C28466 .

Hello Everybody ,

I want toKnow the possible means to transfer continuous  Digital output data of the DelSig ADC  through the USB simultanuously.  and if the answer is using DMA i cant find the Adresses for their TD and channel so i can use it as Periferal to Periferal transfer ADC->USB.

Thanks in advance

Good evening, everyone,

I'm trying to DMA CAN messages directly to a USB IN endpoint, but it does not appear that it is possible to DMA anything *to* USB. It seems that you can only DMA from data received from USB into the PSoC. Is this correct?

I am trying to send any CAN messages that are accepted into one of the mailboxes over to a PC over USB. I can easily do this with the "message received" interrupt on CAN and an interrupt handler running on the ARM but I would like to try to do this using DMA and without CPU intervention. I added a hardware interrupt pin to the CAN component and set up the interrupts so that only "message received" generated an interrupt, then wired this to a DMA component.

The DMA Wizard allows me to configure the DMA component to transfer from SRAM to SRAM, but not from SRAM to a USB IN endpoint. The DMA Wizard will also let me configure the USB DMA component with a source of SRAM, Flash, EEPROM or two very odd options: "USB_EP17_DMA_Done_SR" and "USB_EP8_DMA_Done_SR". The only destination that the USB DMA component can choose is SRAM. I have no way to transfer from SRAM to USB.

What is also odd is that I have only one EP configured, EP1 which is an IN endpoint. I don't know where EP17 and EP8 are coming from.

Can anyone shed some light on this?

I want to generate a AC voltage to drive a resolver.And,I know the WaveDAC8 can generate a sine wave directly.But，it is DC voltage.Dose anyone have a idea to transform it to AC？

Hello,

I recently bought a PSoC 5LP test board and I wanted to use it for measuring consumption.

I followed the guidelines on how to configure the board for low-power operations, but I have a problem : I wanted Vddd = Vdda using a power supply (instead of the on-board regulators on the kit) and I found that Vddd != Vdda although I linked both pins together.

Before I file in a case, i would like to ask the community if any has seen such problem before.

My board is a CY8CKIT-050 revision B.

Thanks,

Hi to all

Does any one help me or guide me for sending word or byte using PWM.

Regards.

Hello,

I'm wondering if Cypress provides PSoC symbol files for ECAD applications.  Specifically, I'm interested in a PSoC1 28-pin DIP symbol for gschem, but any general info on this subject would be appreciated.  I can't seem to dig anything up online about this, but I'd be a little suprised if these files don't exist somewhere already!

Thanks.
