PSoC™ 5, 3 & 1 Forum Discussions

Hi there,

I ordered a CY8C5868AXI-LP035 and I wanted to find out if it is genuine and if it is working correctly. I'm asking this question because I'm not sure I ordered from a honest seller and now I want to verify. I don't have all the required caps yet as they are about to be delivered.

I designed my own PCB and just soldered the PSoC5 on it without any caps. I then connected a KitProg3 and powered it up but the KitProg doesn't detect any PSoC5.

Do you guys have answers to the following questions?

• Would a PSoC5 without any cap that is connected via 5cm long wires to a KitProg3 be found? I made all the required VDDIO, VDDA short connections of course.
• There is no reason the 3.3V of the KitProg3 wouldn't work right?

I inherited a design from a previous engineer and I am not familiar with PSoC. I have been trying to bring up a PSoC5 LP based system that is based on a reference design which itself was based on the CY8CKIT-059 prototyping kit. The previous reference design was a carrier board that adapted the CY8CKIT-059 kit. Barring a few changes to the pin definitions, the firmware should be identical to the previous version.  The carrier design had a LCM-S01602DSR/C LCD MOD 32 DIG 16 X 2 REFLECTIVE display.  The previous design the display function was verified to work and this new PCB was going to just get the firmware ported over with "simple" pin remaps. But after I created the new firmware with remapped pins, I flash the new board with firmware and I dont get any of the original functionalities. The LCD is always showing some garbage characters(left pointing arrows). But i already went and verified the pins on the PSoC driving into the display port and I see actual bits of data being written on the bus. But that still doesn't prove whether the display is correctly configured or not. I have attached a snapshot of my schematic for your reference. Please let me know if i overlooked something obvious.

says to install version 3.5, as does the message I got when trying to install PSoC Creator

Does it have to be 3.5, or is a newer version ok?

3.5 SP1 is dated 2008

Microsoft has several newer version ,including what appears to be the newest,
version 4.8.1, dated 2022

thank you

When creating a custom bootloader, the bootloader "wait for command time" can be specified (See attachment). This value in the stock bootloader that came with some of the PSoC is 2 seconds. Is there a way for bootloaderable to update the wait time in the stock bootloader?

If not, is there a place to request for this feature on the future version of the stock bootloader?

I am connecting a resistor to the DAC output and I am giving sine wave current signal to it of 1 khz freq and 5 micro amp  for 10 times. every time I give this signal for 1 sec. I first start signal generation ,  on this for 1 second and stop signal. give some delay and repeat this process. 

 But every time when I start the signal I found a Spike at the resistor. Why this is coming, and How can I remove it?
