iolinker Family Data Sheet 2 Interfaces 2.1 UART The Universal Asynchronous serial Receiver and Transmitter (UART) is a serial communication device. The configuration used is as follows: • Baud rate: 115200 • 8 data bits, 1 stop bit • Parity: None • LSB first Note that this UART bus requires an external pull-up on its open collector TX line, as described in section 9.1.3. A connection diagram can be seen in figure 1.

A connection diagram can be seen in figure 3.
iolinker Family Data Sheet 3 Timing 3.1 SPI Protocol When writing out an SPI command that requires a reply from the FPGA, the master has to keep writing out n + 1 zero bytes, where n is the number of bytes to be read back. This means that with one byte delay, the FPGA will begin sending out its response bytes. 3.2 Interrupt Pin The interrupt pin INT notifies about state change of any GPIO currently configured as input.
iolinker Family Data Sheet 4 Protocol 4.1 General Message Format Messages to the device are of the format Slave address Command byte Argument bytes Messages from the device are of the format Reply argument bytes Replies are only sent for read operations (W=1, compare table 2). The MSB of the command byte is always 1, and the MSB of all other bytes is 0. This makes it easy to recognize the start of a new message.
iolinker Family Data Sheet 4.4 Command Destination Address The target address byte of the format 0sss ssss allows to target specific slave devices with a command. Each device processes messages only when addressed correctly with its userdefined slave address. The slave address can be configured through the hardware address pins as described in section 9.1.2. The target address 0x7f holds a special function in the protocol, for it is always executed, regardless of the actual slave address.
iolinker Family Data Sheet The version byte can hold values of 0x00 – 0x7f. The GPIO count byte encodes the GPIO count in its lower nibble according to table 4. GPIO count byte value 0x0 0x1 0x2 0x3 GPIO count 14 49 64 192 Table 4: GPIO count encoding 4.7.
iolinker Family Data Sheet Address 0x7f Function Status register Table 6: Register addresses 4.7.4 REA – Read pin states Function Command byte Argument list Reply argument list Example arguments Read the state of pin range x to y 0xC7 First pin address to read, last pin address to read Current pin states 0x01 0x00 | 0x7f 0x00 (Read pins P1 to P127 ) To read pin states, use the first and the last pin address as parameters. If the last pin number equals 0, only one pin state will be read.
iolinker Family Data Sheet 4.7.6 SYN – Synchronize Buffered IO State Function Command byte Argument list Enable command buffering 0x88 – Use this command before you start issuing write commands you want to buffer. To end the buffer process, issue a TRG command. 4.7.7 TRG – Trigger IO State Buffer Execution Function Command byte Argument list Execute all buffered IO states (i.e. copy buffer to current and write out pin states) 0x89 – Use this command to write out the buffered IO states, i.e.
iolinker Family Data Sheet The PWM_R argument byte has the format 0rrr rrrr, i.e. there are 128 possible values between 0 and 127, as seen in table 7. PWM_R byte value 0x00 0x01 ... 0x3f 0x40 ... 0x7f PWM ratio 0:127 1:127 ... 63:127 64:127 ... 127:127 PWM ratio in % 0% 0.8% ... 49.6% 50.4% ... 100% Table 7: PWM_R byte values and their meaning Note that the output state needs to be high for PWM output to be active. To turn PWM off, set the PWM ratio to 100%. 4.7.
iolinker Family Data Sheet 5 Pin Addresses Pin addresses are encoded in two bytes of the format 0PPPPPPP 00000PPP, where the first byte encodes the less significant 7 bits of the pin number, and the second byte encodes the more significant bits of the pin number. On devices with less than 128 pins, the second byte is always 0x00. The second byte for pin numbers below 128 is therefore 0x00. Examples for physical pin addresses are listed in table 8.
