Configuration bits can also be programming in Low-voltage ICSP programming mode when Vdd is usually in the range of 2. Thanks Edited April 9 by david bowie. Thanks in advance Davide. Thanks for your thoughts, Nic. The version that uses bursts does not have this problem because its measurement timing is determined by the instruction loop in the PIC16FA chip. The original “oscilloscope” program without bursts of readings had irregularities caused by the multi-tasking of Linux. Other specialized drivers and user programs work through it.

In Vivado it is showing: Hi HamzehmekI have sent you a PM about this.

These are demonstrated by scope. Alternatively, the C-library routine nice can be placed around the time-sensitive data collection code. The USB nature of the communication is hidden from the application as data is exchanged between the device and the application program.

Linux Communication with Devices Using the FTDI FTC USB Interface Chip

Did’pings’ with a 3 byte request and byte response successfully on one of these “problem computers”. The protocols, descriptors, and many other important details of vtdi USB 2. Hi gytisb92I have sent you a PM about this. The driver blurb says “single-port”, but in fact, it works with the dual-port FTC chip.

Also, if you had made the power directory your working directory, you would have found a somewhat confusing result since that directory will be removed and recreated on a different filesystem inode number when the power condition is changed.

On other occasions, I might want the driver to unbind. This prevents the normal log files from being filled with the massive debug information.

Bulk erases need 4. Hello, I was programming an external fth board, forgot to uncheck the digilent HS2 when I was programming it. This can be very helpful. I’ll let you know if it works reliably.

Re: [Xylo-SDR] FTDI FT2232C USB interface

Hello everybody, I am having the same problem the Digilent HS2. See samples of my routines: The version that uses bursts does not have this rtdi because its measurement timing is determined by the instruction loop in the PIC16FA chip.

Hi ozoeI have sent you a PM about this.

Its bytes can be examined using the hexedit program:. The first 5 chapters and Chapter 9 are particularly relevant to USB programming. Any noise induced onto your ground which is tied to USB ground may cause de-enumeration problems on computers with ‘marginal’ USB hub designs I’m seeing this typically on Intel USB hosts in Gateway and Dell computers Also, I would definately recommend use of opto -or- galvanic isolation between FTDI chip and your microcontroller if your device will be connecting to anything ‘harsh’.


The original code in the 16Fa only made one reading per command. Two-byte data manufacturer id, product id, USB version, and Unicode characters are bit words which are stored with the low byte lower in memory.

Connect FTDI USB transciever to PIC18F8722 – SPI or USART?

Hi rettileI have sent you a PM about this. Posted December 1, The library libusb will also usually be installed. It is a good idea to make sure that the bitbang example described above works correctly to be sure that the library and device are talking to each other, before changing the EEPROM.

Haven’t received registration validation E-mail? When using this version, be sure to also use the modified libftdi code since the ftdi eeprom routines needed modification to work with the FTC chip.

Maxim’s documentation of their DS18S20 single-wire chip thermometer is also complete. Please, can you help me in some way?
