PSoC™ 5, 3 & 1 Forum Discussions

Hi Guys,

I have need to latch an event, I thought this would be very simple but it is putting up quite a fight! Firstly I tried to make an RS type flip flop from two NOR gates, this refused to latch at all for some reason. I am guessing the async logic is synthesized by use of sync-subcomponents? Anyhow, it really didn't want to play.

 So, I tried to hook up a D type flip flop and turn the clock off by means of an AND gate and the negated output of the d-type. (As attached) This seemed to work, right up to the point where I connected the D-type output to the clock input so again it looks like some kinda race condition.

 I need a fast acting latch, that I can reset. any ideas? It seemed such a simple bit of the circuit...

 Hi all,

I am a complete noob when it comes to PSoC.

How can I dynamically set a GPIO pin as input or output, as and when needed (as in the 1-wire protocol) on the PSoC 5?

In the 1-wire protocol, I have to pull the line low for a certain amount of time, and then "release" the line by setting the pin as an input, and then read the value on the line.

Can anyone please help me with this?

Hello there,

I just want to know what the development kit will delivered for this PSoC5 contest?

I need to start to looking for it possibilities of hardware and the build components on the PCB of this KIT.

Kind Regards,

Hello,

i want to display a ADC result in decimal on the display. I have found something to display in float but not in decimal.

char *pResult;            // Pointer used to store the result returned by ftoa function
int iStatus;                  // Status variable for the ftoa function

LCD_Position(1,5);

pResult = ftoa(ADC_value,&iStatus );
 LCD_PrString(pResult);
