FTDI have produced a newly updated library to handle all the MPSSE commands necessary to interface to a device using the I2C protocol. The MPSSE is currently available on the FT2232D, FT2232H, FT4232H and FT232H chips, which communicate with a PC (or an application processor) over the USB interface. The purpose of the MPSSE command processor is to communicate with devices which use synchronous protocols (such as … This means that you need to use a different chip if you want to convert SPI to USB .i.e:FT220X , or I2C to USB .i.e:FT201X , …etc. Each function or action you need from MPSSE to do is driven by a command. FTDI have produced a newly updated library to handle all the MPSSE commands necessary to interface to a device using the I2C protocol. Yahya is the editor-in-chief of Atadiat and believes in the importance of sharing free, practical, spam-free and high quality written content with others. Each mpsse is accessed via its own ftdi context structure and initialised with the calls above. ftdi::spi_command Set the SPI command word to be bits in length, where may be zero to 64. You will see FTDI chip in 2 places: under ‘Ports (COM & LPT)’ and ‘Universal Serial Bus controllers’ for the reason mentioned above. To expedite application development, FTDI has provided libraries which handle the MPSSE commands to emulate several protocols. I'm of the understanding that each mpsse can be accessed separately provided a separate ftdi context is used (which I do). Just select Device ->Serial Protocol->Connection from Polymorphic drop-down menu. To send a command between your application and MPSSE via USB, you need to send the data using ‘FT_Write’  api. I did not come across the references to a bit fields table of the GPIO commands parameters. In the diagram below a demonstration of bits order of high and low GPIO ports. Finally I get this ebook, thanks for all these Mpsse Basics Ftdi I can get now! Does anybody have any ideas? The newer FTDI chips have a very strong capability in this area, which they call Multi-Protocol Synchronous Serial Engine, or MPSSE. In a synchronous protocol (such as SPI or I2C) both clock and data signals are transmitted from sender to receiver, so the two remain in sync. Here is an example of how to read from MPSSE. In the next part we will see how to do a serial communication using SPI device and FT2232H. Now, let’s do a real usage of MPSSE by setting up a GPIO. I had to figure that in practice. if (ftdi_init (&mpsse-> ftdi) == 0) {/* Set the FTDI interface */ ftdi_set_interface (&mpsse-> ftdi, interface); /* Open the specified device */ if (ftdi_usb_open_dev (&mpsse-> ftdi, usb_dev, usb_if) == 0) {mpsse-> mode = mode; mpsse-> status = STOPPED; mpsse-> endianess = endianess; /* Set the appropriate transfer size for the requested protocol */ if (mpsse-> mode == I2C) This is accomplished by the MPSSE within the FT232H device which has the ability to emulate synchronous serial protocols while handling all the USB signalling and protocols. Mpsse Basics Ftdi - dev.babyflix.net Mpsse Basics Ftdi “Multi-Protocol Synchronous Serial Engine” or MPSSE is the name of the block inside new generation chips from FTDI to provide the flexibility of USB to a variety of serial protocols conversion. 6 3.1. So customers can use the same chip to convert USB to UART or to SPI or other serial protocols. 2- Make sure that your application and MPSSE are in a right sync. ftHandle  is a pointer to a variable of type FT_HANDLE where the handle will be stored. LibMPSSE is not required to run simple SPI. Config Command: ftdi_layout_init data direction Later, include in the place of using D2XX APIs, the ‘ftd2xx.h’ header. This will set up the direction of the first 8 lines and force a value on the bits that are set as output. Field name Description Type Versions; ftdi-mpsse.bad_command.command: Received invalid command: Unsigned integer, 1 byte: 3.4.0: ftdi-mpsse.bad_command.error The usb_control_msg routine of libusb wraps these commands into the correct ioctl format.

The Multi Protocol Synchronous Serial Engine (MPSSE) is generic hardware found in several FTDI chips that allows these chips to communicate with a synchronous serial device such an I 2 C device, an SPI device or a JTAG device. However, if you don’t want to understand and use MPSSE commands directly, then a higher-level of abstraction is available in other libraries from FTDI. Moreover there is no "NOP" instruction on FTDI, so it would also be quite difficult to execute the SPI commands with a known/configurable pace. You can see that by opening ‘device manager’ in Windows after connecting FT2232H. What documentation says about the process is that “the use of the bad command detection is the recommended method of determining whether the MPSSE is in sync with the application program. Config Command: ftdi_channel channel. A separate page has been created where the LibMPSSE library can be downloaded, along with code examples and release notes. Embedded Hardware Engineer interested in open hardware and was born in the same year as Linux. His experience with Embedded Systems includes developing firmware with bare-metal C and Arduino, designing PCB&schematic and content creation. You will find later that MPSSE is totally driven by commands, and that’s why it’s called a command processor. You will find later that MPSSE is totally driven by commands, and that’s why it’s called a command processor. Required fields are marked *. You'll need "ftdi_set_bitmode(pFtdiC, 0, BITMODE_MPSSE)", and you should use the invalid command stuff to synchronize with the "command processor". For this end, MPSSE has a special command called ’bad command’ and when it is detected, the MPSSE returns the value of 0xFA, followed by the byte that caused the bad command. Mpsse Basics Ftdi - fiyprqsx.trko.30101.fifa2016coins.co The FT2232D, FT232H, FT2232H and FT4232H incorporate a command processor called the Multi-Protocol Synchronous Serial Engine (MPSSE).
