Discussion - Software / Re: D2XX Write Problem
« on: May 31, 2020, 02:43:00 PM »

If any, what is the difference between debug mode and normal execution on ft905?
It is to help me better understand what is going wrong in my project.

Best Regards.

Discussion - Software / D2XX Write Problem
« on: May 29, 2020, 12:55:53 PM »

I try to develop a GUI for FT9xx MCU board.
There is simple comparison statement in my firmware code.
It compare variable which is coming from GUI(use D2XX_Read function)
Then select a statement and then send a message to GUI.

GUI and firmware working debug mode. I can read and write the board via GUI.
However when I tried to run without debug mode, GUI froze when try to read a variable from the board.
I added delay after read and write function but nothing was change.

I can't find ftd2xx_api source code, is there anybody to know where I can source code?

Thank you for your reply.

I checked the Aardvark Adapter but nothing change.
Also I design a basic custom code to detect an interrupt but it didn't.

Best Regards.

Discussion - Software / FT905 I2C Slave Example
« on: March 27, 2020, 01:41:57 PM »
I am using FT905(Revision C) MCU on my custom board. I would like to program as an I2C Slave.
I looked 'AN_360 FT9xx Example Applications' and I use I2C Slave Example 1 code to try.
But this code didn't work. I use 'Aardvark I2C/SPI Host Adapter' as master.
I think it cannot detec interrupts. How can I fix this issue?

Best Regards.

Discussion - Software / FT90x Transferring Data via USB
« on: August 20, 2019, 08:12:37 AM »

I try to make USB to I2C/SPI with ft90x MCU and I want to make a GUI with MS Visual Studio but Bridgetek supports eclipse so I decided to make a main function which will be include all source codes and receive data from GUI for use them then I will save these mcu memory with eclipse. After that I will make a GUI with FTD2XX.NET , this GUI will only receive data from the user(i.e speed mode,clock speed, slave address etc.)  and send these data mcu over USB with FT_Write function but i confused where to write data? I search D2XX Programmer's Guide and says 'Write data to the device' so can you give more detail?

Finally, I design a PCB and itit hasn't arrived yet so all of them is a theory.Is it possible this theory?

Best Regards.

Discussion - Software / FT905L Toolchain and Building DLL
« on: July 29, 2019, 12:41:35 PM »

I am trying to create a DLL for ft905L and I am using toolchain with prepared header/c files but i cannot create DLL eclipse always give an error like
"-shared not supported" and  make: *** [libftLibrary.so] Error 1 I search and I couldn't find any answer how can I fix this issue? Moreover I try that with Visual Studio and all codes give errors.

Discussion - Hardware / FT906L USB Connection
« on: July 02, 2019, 11:51:28 AM »
Hello everyone,

I use FT906L and i want to use USB device connection for send commands and power supply.
Do i connect VUSB and HREF to ground?
But i wonder that i should connect pullup/down resistor or not?
Is there any schematics about that and there is data line 22k resistor in some documents where should i connect resistor?
Some microcontroller need a RTC Oscillator because USB don't run, FT906L needs or not RTC?

Best regards.

Discussion - Hardware / FT906L GPIO Voltage Level
« on: June 26, 2019, 05:58:08 AM »

I am working on i2c/spi with Ft906L and I want to use other pins as GPIO but I couldn't find GPIO pins characteristic.
I wonder that if I use those pins what is the voltage level?
