PSoC 4 MCU

Anonymous

Hello,

   

I am using a PSoC BLE Pioneer Kit to interface the PSoC 4 BLE with a 4D Systems uLCD-32PT display which communicates to host microcontrollers using TX and RX pins. I've figured out that I have to use a UART component in PSoC Creator. But Creator has two UART component blocks - UART (SCB Mode) and UART. I'm confused about which one I should be using.

   

Basically, the steps that I have to follow are writing sequences of bytes (that correspond to certain commands such as "Set Font" or "Set Font Color") of data to the display.

   

The sequence that I have to send - 0x55, 0x46, 0x03, 0x59, 0x04, 0x02, 0x54, 0x43, 0x00, 0x00, 0xFF, 0xFF.

   

Which UART component would be appropriate here?

   

I've attached the datasheet of the LCD display and also the commands database.

   

Thanks and regards,

   

Ganesh

Differences between SCB and UDB implementation

   

SCB

   

Dedicated IO-pins

   

Deeper FIFO

   

UDB

   

Free routing of IO-Pins, but no use of port4 and greater

   

Smaller (4 byte)  FIFO

   

I would suggest you to

   

Use the SCB module when restrictions are alright. The UDB block is quite more versatile and you can use that even for self-made components (after a lot of reading the appropriate manuals)

Hi Bob, in case of UDB UART, will I be able to send and receive data via a hyperterminal such as PuTTY?

Both UARTs can use the USB-UART bridge to display / read from PuTTY. Have a look into your kit's schematic to see which pins you have to connect.
