PSoC™ 6 Forum Discussions

Hi,

I was reading the Architecture Technical Manual, and on page 38 it is mentioned that "The CPUSS has up to three identical SRAM controllers; see the device datasheet for details." I tried to find clear information about the "three" SRAM controllers on the device datasheet but I couldn't clarify this question:

Is the SRAM a one block memory or a 3 block separate memory with each block having its own controller and connection to the system bus? To give a little more color on my question, I was wondering if the SRAM will suffer from contention delays if both cores are accessing simultaneously this memory.

Thanks.

i've been succesfull with creating custom libraries  and creating a project that  uses the PDL to toggle an LED to a digital pin on the Arduino header?

Using the PSoC Arduino Form factor pins to connect an Arduino Shield to a PSOC6 kit using Modus toolbox?

Can you create your own Library in ModusToolbox?

Now I am attempting to combine this knowledge to Create a libray that implements the Arduino digital pin  calls .

I have a cutom library project called arduino., that I created using the steps that I did to create a custom library.the 2 files gpio.c and  gpio.h have the  2 functions impleenting the arduino calls:

1. digitalWrite(LED, HIGH/LOW); // set the pin HIGH OR LOW
2. delay(500); // for 500ms

I'm stuck at implementing the PDL api into my custom library?

I don't see anyware from the IDE to run the Device configurator  to select the BSP and the Libraries for this  project.?

Is this the way to implement the PDL calls in a reusable library? or is there a better way?

The screen shot below shows MTD with the Project, gpio.c and  the error that I would expect to receive.

Any thoughts on what I might be missing out on?

How can I modify only a specified section of Flash during development?
I would like to be able to program a 2nd firmware image in a location offset from an existing firmware image on a PSoC 61 such that I can test modifications to the 2nd firmware without affecting the first.

What serial interface examples exist that support communication to the TFT driver, Sitronix ST7789V on CY8CKIT-028-TFT which is used on CY8CKIT-062-WiFi-BT?

Sitronix ST7789V uses similar interfaces to Ilitek Ili9163C which is found on DisplayTech DT018ATFT. The parallel interfaces to these TFTs is rather straightforward. For applications that are pin limited yet don’t need the full bandwidth, a serial interface is preferred.

These serial interfaces are NOT standard. The serial interfaces are marked as SPI on the Display and Display Driver datasheets. However, they appear to be custom:

• 3-line Serial Interface: CSX, SDA, SCL
• 4-line Serial Interface: CSX, D/CX, SDA, SCL

The 3-pins serial use: CSX (chip enable), SCL(serial clock) and SDA(serial data input/output) and the 4-pins serial use: CSX(chip enable), D/CX(data/ command select), SCL(serial clock), and SDA(serial data input/output).

Note: There’s a caveat when using 3-pin interface that a 9-bit packet is used to support the D/CX function.

Note: It is interesting that that Display and Driver datasheets note the DB0 pin is also an SDA. It doesn’t specifically state, but I wonder if that 2^nd SDA could be used to support Full-Duplex mode.??? If it could, a standard SPI driver might work.

Standard SPI supports full-duplex with clock, two data lines and Chip Select. There is a 3-wire version (aka National’s Microwire) of SPI, which uses half-duplex, single data line for transmit and receive.

• SPI signals: SCLK, MOSI, MISO, CS
• 3-wire SPI signals: SCLK, SISO, CS

ModusToolbox’s Device Configurator has an option for “National Semiconductor (Microwire)” when configuring a Serial Interface. It doesn’t appear to support the 9-bit packet that has the preceding D/CX bit.

I’d prefer NOT to bit bang the interface.

Hello,
I have a project on PSoC 3 (CY8C3246PVI-147) that I would like to transport to PSoC 6 (CY8C6347BZI-BLD43), however, in the TopDesign of the project for PSoC 6 some components appear to be incompatible and I cannot find their counterparts in the component catalog. How can this be solved?
Thank you very much
