PSoC™ 5, 3 & 1 Forum Discussions

Hi,

I was wondering if it is possible to configure the Default ID settings for a LIN Slave 4.0 component on the PSoC 5LP to receive frames with PID 0x3C and 0x3D. The datasheet seems to indicate that this isn't possible, but I just wanted to confirm.

Thanks,

Daniel

hi;

I'm trying to run an LCD on kit059.

but when selecting pins p12 [6: 0] and p12 [7: 1] blue others white.

for example, if I select p0 [6: 0], the lcd does not work. nothing on the screen.

but if I select p12 [6: 0] or p12 [7: 1], the lcd works.it works when you assign another task to the other pins. but I don't understand what the problem is.

Do we have to choose p12 [6: 0] or p12 [7: 1]?

Best Regards.

Hi,

I'm using PSOC Creator 4.2 with a PSoC 3 chip.  I have on PSoC design that is going on two boards with different form factors, so the PSoC 3 chip will require different pinouts on the two boards.   I'd really like to avoid having to support two separate projects in two separate rev control repos.

Question: How can I edit one file to generate the two unique pinouts.  Any ideas?

Thanks,

hello ,

i have two situations and some questions show below.

a)i have a project need to measure AC voltage and current.both of voltage and current sensors Vout have dc offset which depend on how much power source i give them.

i connect CY8CKIT-059 to my computer through usb port and i measure its Vdd,it shows 4.6V.so i provide this Vdd to my sensor then sensor's dc offset goes to 2.3V at AC 0V.

but when i disconnect usb port and connect it again,Vdd will be changed to 4.52V sometimes will be 4.38 or 4.44V.it will cause dc offset change to 2.25V or 2.19V at AC 0V.

1.could someone tell me why Vdd is not stable?

b)i convert adc value to mV,the value should be 2300V at 0V.unfortunately there are some noise to cause value unstable(value would be 2324,2285,2292...).

i have gone through datasheet and don't understand description that i marked.

1.do that mean if i want to filter the noise,i can connect sensor Vout to P0[2] or P0[4]?

2.if i choose Internal Vref,bypassed mode,i can't choose those as analog high-z pins.is that right?

3.what if i set Internal Vref,bypassed mode and higher conversion rate,will the value be more stable than Internal Vref mode?

all i want to do is filter noise and eliminate error as much as i can.but i have no idea about it.

need some suggestions,please.

--- Inquiry background ---

CY8CMBR3108 does not have a reset terminal.

For example, I want to turn off the power when malfunctioning due to noise.

At this time, I want to turn off the power after dropping pins 14 to 16 to low level at the host.

--------------------------

I want to confirm the output terminal configuration of pins 14 to 16 of CY8CMBR3108.

I understand that pins 14-16 are open drain terminals.

Q1.

Do these pins not output High in the internal settings?

*

I don't think pins 14-16 are open drain and these pins never output high.

I want to make sure that this is correct.

Hi,

the attached project tries to sample a differentiell voltage into an array. Each time a button is pressed these shall be sampled and stored into an array. After aquiring the sample array shall be written out to the UART.

I'm using the Cy8CKit-059 and see useless values even I short cut the inputs and ground them (expecting to see 0V).

I expect to see values between +/- 2048 mV, even not approx. 20V

What's gone wrong here and how can  fix it?

Thanks
