You have learned a lesson of using the PSoC kits they have a lot of uses and Cypress tries make sure you can use the kit for all types of functions. This causes issues when you need to use a lot of pins in a row like the LCD component. So it is better to look for one of the LCD devices that work on I2C so you can use just about any free pin and you only need a few pins. They made a Component for the PSoC 4 that you can use any pin on any port to drive the LCD component. I have found this component to be very useful for a lot of projects. It doesn't work on the PSoC 5 devices however. In your own design you can get around these issues as you are defining the Pins and your design would not have these restrictions.
Since port0 is mostly used for analog purposes there have been mase some things easier for the user. To stabilize tnternal and external reference voltages there are 1.0µF capacitors (C9, C12, C13) connected to some Port0 pins as Dana already stated. Unsolder those caps or use (preferred) other pins.
Those caps are for -
22.214.171.124 System Capacitors
There are seven capacitors on the PSoC 5LP Prototyping Kit, used when ADC operation at high
frequencies, CapSense or external 32kHz crystal oscillator is required in the application.
■ Four ADC bypass capacitors: Required for proper ADC sampling at higher frequencies:
❐ C9 and C12 - For two SAR ADCs
❐ C7 and C13 - For Delta Sigma ADC
■ A CapSense capacitor (CMOD): Required for proper CapSense functionality.
■ Two biasing capacitors: Required for interfacing an external 32kHz crystal oscillator. These
capacitors are added in the Rev *A version of the PSoC 5LP Prototyping Kit.
And you can see on schematic what cap is used with which pin.
Thanks, guys! You helped a lot.
Yes, I have to be pretty more attentive and look through the schematics before asking at the forum.
However, thank you all for fast and helpful response. This topic can be closed.
Glad to help.
