Re: require code for designing on EVE2-70A

Hi madhusudan.jadhav, I believe you mentioned you were trying out the Basic EVE Demo as a quick test to verify that your hardware works. Please note that the Basic EVE Demo was developed to run on an EVE display connected to a USB2SPI Bridge adapter. Were you able to run the Basic EVE Demo properly ...

Re: require code for designing on EVE2-70A

Hi madhusudan.jadhav,

Which test executable are you running, and which display variant are you using?

Re: EVE2 - Button Text color besides White

Hi Jwizard, You should be able to configure the color of your buttons using the CMD_FGCOLOR command. The color of your text can be set by using the COLOR_RGB display list/Co-processor command. Here's an example using our EVE library: Send_CMD(CMD_DLSTART); Send_CMD(CLEAR_COLOR_RGB(255,255,255)); Sen...

Re: require code for designing on EVE2-70A

Hi Madhausen,

I took a quick look at your startup code. Please note, you don't need to write anything to REG_CPURESET prior to reading the register.

All you'll need to do is perform a rd8(REG_RESET) and read what is in the Reset Register.

Cheers,
Daniel

Re: Drawing Scope on Eve2-50G

Hi Chris, Take a look at the Signals example that FTDI posted on their site. The Signals demo uses stored data to recreate sine, triangle, and ECG heartbeat waveforms on screen. You may be able to modify one of the waveform functions that they use for your own application. It isn't quite the same as...

Re: EVE2-43G brightness increase possible?

Hi Paul, Based on the values you're measuring, it sounds like the display is receiving sufficient power, so the LED's should be providing peak brightness. Our current EVE2-43G has a typical brightness rating of 472nits, which should be enough for indoor applications. Typical cell phones hover around...

Re: EVE2-43G intialization difficulty

Hi Paul, You are correct. The BL_VDD pins on the EVE2 have a different functionality than the BL_VDD pins on the EVE3. The EVE2 came with two sets of power and ground pins which were only capable of supplying 500mA each (1A) to the display. The BL_VDD lines were also part of the 3.3V rail, but these...

Re: Python Command Wrapper

Hey nasax,

Wow, that's quite the wrapper. We really appreciate all of the work you've done and I'm sure plenty of people with find your wrapper very useful in their product development.

Thanks again,

Re: EVE2-43G intialization difficulty

Hi Paul, I'm glad to hear that you were able to resolve your communication issues. As for the power situation, we offer a way to power the back light separately from the logic on our new EVE3 boards. From the factory, the EVE3 is configured so that both the back light and logic use the same 3.3V rai...

Hi Madhusudan.jadhav,

What are you trying to draw on the screen? Could you provide a snippet of your code?

Re: EVE2-43G intialization difficulty

Hi Paul, Your setup looks correct. That said, there could be other factors of your setup which may be affecting the display's operation. During testing here, we found that the FT81x is very stingy about how our traces were routed. For your situation, I suggest using the USB2SPI as a method of verify...

Re: EVE2-43G intialization difficulty

Hi Paul, Welcome to the forums! Out of curiosity, were you able to purchase a USB2SPI bridge adapter, or an Arduino Scoodo Shield? We can guarantee that our demos will run on our hardware, and we strongly advise purchasing either of these pieces to verify that your display is working. Do you have a ...
