MSVC codes not working

(1/2) > >>

nelson_lobo:
I've been trying to start my BT815 setup provided by panasys http://www.panadisplay.com/ftdi-intelligent-display/7-tft-lcd-with-ctp-with-bt815-paf70uwfnwc01.html

I tried running the MSVC codes provided in your sample codes section. I'm currently using Visual Studio 2019 Community edition.
The code seems to build without any errors. It does prompt me to Retarget Projects Windows SDK to 10.0 and Platform toolset to v1.42

Once that's done when I try running in the debug mode.
With my breakpoint set at "line#1019 BootConfig(phost);"  the CMD prompt pops up with
Init FT4222 as master device failed!
FT4222_SPI_SetDrivingStrength failed!
Init FT4222 as GPIO interface failed!


How do I fix this issue?
PS: I did try this : http://www.ftdicommunity.com/index.php?topic=130.0
I copied the exe generated in the debug folder to the LibFT4222-v1.43 folder containting 1)LibFT4222.dll 2)LibFT4222.lib :

I get this :
FT4222_SPIMaster_SingleWrite failed, SizeTransfered is 0 with status 10
Gpu_Hal_FT4222_Rd failed

Please check attachments for more information.

Hello,

Please make sure to use the samples below which include BT81x support and to select the device in the platform.h file.
EVE_Samples_v1.1.0_RC_28062019.zip

We recommend to copy the LibFT4222H lib and dll files from our libFT4222H library into the same location as your exe in your EVE sample app directory to ensure that the sample app can find the library.

I do have both a PAF70 and a PAF90 and support for the PAF90 in my code library and the display parameters are the same as for example the ME813A.

Hi,
I have followed your instructions and did the needful.
The IDE prompted me the same again to Retarget Project Windows SDK to 10.0 and Platform Toolset to 1.42

I ran App_Gauges in debug mode, replaced the .dll and .lib files in Bin/Msvc folder and also in the Debug folder which is created after compilation. But the outcome was the same as above.

Hello,

It looks like the SPI master init is failing, which is causing the subsequent calls to return a FT4222_IS_NOT_SPI_MODE error.
Replacing the FT4222 Lib/DLL files in the project normally resolves this issue.

Are you by any chance using a USB 3.0 port on a windows 7 machine?
