Three buttons are used to command the circuit. The unit provides 10 way speed control from 0 to 9. The current speed is displayed in a seven segment display. In the Video below you can check out the project in action.

FTRL is an impressive chip because it implements full v2. The FTR adds two new functions compared with its predecessors, effectively making it a "3-in-1" chip for some application areas. A unique number the FTDIChip-ID is burnt into the device during manufacture and is readable over USB, thus forming the basis of a security dongle which can be used to protect customer application software from being copied.

FTRL breakout board is breadboard compatibile. The clock circuit has now been integrated onto the device meaning that no crystal or ceramic resonator is required. However, if preferred, an external 12MHz crystal can be used as the clock source.

These three resistors have now been integrated onto the device. This pin required an external R-C filter.


There is also the option to bring out bit bang mode read and write strobes see below. The device is supplied with the most commonly used pin definitions pre-programmed - see Section 9 for details.

Data packets can be sent to the device and they will be sequentially sent to the interface at a rate controlled by an internal timer equivalent to the baud rate prescaler. This option will be described more fully in a separate application note.

Synchronous Bit Bang Mode - Synchronous bit bang mode differs from asynchronous bit bang mode in that the interface pins are only read when the device is written to. Thus making it easier for the controlling program to measure the response to an output stimulus as the data returned is synchronous to the output data.

An application note describing this feature is available separately from www. Bus powered designs would still take their supply from the 5V on the USB bus, but for self powered designs where only 3. In this mode any residual voltage on external circuitry is bled to GND when power is removed, thus ensuring that external circuitry controlled by PWREN resets reliably when power is restored.

This ID number cannot be reprogrammed by product manufacturers or end-users. This allows the possibility of using FTR based dongles for software licensing. Web based applications can be used to maintain product licensing this way.

Programmable Receive Buffer Timeout - The receive buffer timeout is used to flush remaining data from the receive buffer. This time defaults to 16ms, but is programmable over USB in 1ms increments from 1ms to ms, thus allowing the device to be optimised for protocols that require fast response times from short data packets.

This gives achievable baud rates in the range When a non-standard baud rate is required simply pass the required baud rate value to the driver as normal, and the FTDI driver will calculate the required divisor, and set the baud rate.

FTRL is an impressive chip because it implements full v USB protocol, needs no external crystal, has integrated EEPROM .

2 Wire Serial Communication (I2C) EEPROM - The back bone of any microprocessor project. These 8 pin chips need only two wires to communicate and retain their data even with power failure.

These days, Arduino simulators make it possible for anyone, meaning both beginners and professional circuit designers to learn, program . Jan 06,  · This is the second part of my previous tutorial about how to do simple programable pedals switcher (or looper) now with a MEGA Arduino to achieve 8 storable loops on 8 presets.

I recommend to take it a view for the coding part explanation and how the things are tight together. Note that is. This looks like it'll be quite useful - though a write function that doesn't take a registerAddress might be nice.

Some homebrew I2C devices don't seem to use a register address for writes (which confuses me), and other I2C devices (like the 24LC EEPROM) use multi-byte addresses.
