(that would be the max), that said now what is the baudrate supported by your embedded device.

Knowing that there is at least a 1 milli-second latency in USB 2.0 full speed what ever youДo, you are transfering from a USB point of view 384*1000/1024, that is 375 K byte/s in theory I was probably not completely underdanding the in and out of the USB 2.0 full speed FTDI technology.ДЇor example let's say you are using the FT232RL and transfering 384 bytes at the time withДЇT_Write(). Working with the FT232RL and the FT231X chip, but I can't tell you what changed.

Somehow I was able to update my C# library to send data in buffer of 32k in FT_Write() and it is

I also did some research on faster serial port communication from. In 2016, I read every thing you can read about FTDI USB 2.0 Full speed chip, I came to theД¬onclusion that FT_Write should support up to 64K (see datasheet for the following chip I later used the chip FT231X which has a larger buffer (1k, 512 byte receive buffer and 512 byte transmit buffer).ДЄnd was able to transfer with FT_Write() 1k and 2k buffer of data, therefore more than doubling my speed of transfer. Using a size of 500 bytes would still work but above 600 bytes thing would not work. In 2015 I was under the impression that with FTDI chip FT232RL the size of 384 bytes was working wellДЄnd the number comes from the chip datasheet (128 byte receive buffer and 256 byte transmit buffer). In other words it is complicated (see more below in my referenced blog post). The expected numbers of transfer speed never really match at There are the USB 2.0 specification or the FTDI FT232RL specification and then there is I mostly work in the mode Synchronous Bitbanging rather than UART but after all it is the same While working on the library for my USB device Nusbio.

I also saw the same problem of API FT_Write() not working right if too much data was passed, Is that the data will be written to the device with 64 bytes per USBДЄny idea what's the proper fix for these issues? Is it related to FTDI initialization? My driver version is 2.12.16.0 (). Win32 API, FT_Write if using the D2XX classic interface orДЇT_WriteFile if using the D2XX FT_W32 interface). Write function call (either WriteFile for a VCP application using the When writing data to an FTDI device, as much data as possible shouldД«e buffered in the application and written to the device in a single Note: I use large chunk because of suggestion I found in FTDI application note below: I believe my work around is not a graceful solution. It still happened every couple hundred packets, but at least I can send the whole file (2 MB). I found a work around, by purging both TX and Rx, followed by ResetDevice() call recovered the chip. The problem is the function returns '0 byte sent' every couple hundred packets and stuck. Smaller chunk (I tried 64 bytes) works fine. Note: These issues below appear when I use 1KB chunk size.

I use FTDI Windows driver, I use the classic FT_Write() API function as my code is cross-platform. My application on PC sends a file (2 MB) in chunks of 1 KB to embedded device.
