This data can be retrieved or downloaded to another system via the controlling single-board computer using tcP/ip or serial communication, or the card itself may be removed to facilitate transferring the data to another location The Dynamic C implementation of the FAT file system can be used with the sf1000 serial flash cards to store and access the data via a directory structure that can be accessed through Unix or dos style paths. The standard directory structure allows for monitoring, logging, Web browsing and ftp updates of the files User's manual SF1000 GETTING STARTED Headers The SF1000 comes with a 10-pin, 2 mm, 5x2 header located at JI as shown in Figure 1. Headers, either plugs or sockets, SMT or through-hole, may also be installed at J2 or J3. The pinouts for these positions are identical and allow for a connecting cable to be hooked up in different ways There is also a location at J4 for a 7-pin in-line header or socket with 0. 1"spacing Position 6 at J4 is not used, which allows this connection to be keyed 5×2 header installed R5与 J3 J2 带P optional optiona/7×1 5×2 headers in-line header Figure 1. User Connection Points to SF1000 User's manual Pinout Only six connections are required to interface the SF1000 with a rabbit Semiconductor board +5V round ° Chip select input Serial clock Input Serial data inpu Serial Data Output. This output is inverted because the serial flash is a 3 V part and the signal is converted to 5V via an inverting transistor buffer Figure 2 shows the pinouts for the sF1000 header locations J1-J3 SER OUT 1 ●2GND 1■| SER OUT SER CLK3●●4+5V GND C.5 6 SER IN 3●| SER CLK n.c.7●●|8cs 4●|+5V nc.9●●10n.c 5●sER|N 7●|/cs Figure 2. SF1000 Pinout SF1000 Connections Rabbit 2000 and rabbit 3000 Boards Serial port b on all the rabbit-based boards (except the bl2000 and the BL2500)is the recommended port to use to connect the SF1000 serial flash card. Table 2 lists the connections Table 2. sF1000 Connections to rabbit-Based board (except BL2000 and BL2500) SF1000 Signal Rabbit-Based board 5v 5v GND GND SER OUT PC5(RXB) SER IN PC4(TXB) Serial port b SER CLK PB0 (CLKB) user-selected output bit /CS ( default is PB7) Refer to the user's manual for you rabbit-based single-board computer for the locations of these connection pins While Serial Port b is the recommended port for connecting the SF1000 serial flash card, the programming port(Serial Port A), which is compatible with the header pinout on header J1 on the SF1000, or a parallel I/O port may also be used a connector cable is available from rabbit semiconduc- tor if you wish to connect the SF1000 to the programming port (Serial Port A) on your rabbit-based board Note that the programming port(Serial Port a) will not be available for application development and debugging if it is used to connect the sf1000 serial flash card Refer to the "Programming Information? section of the eu "Software"chapter for details of the software associated with your choice of connections The RCM3300 Prototyping Board, which can be used with RCM3000, RCM3 100 RCM3200. RCM3300/RCM3310 and RCm3360/RCM3370 RabbitCore modules has a built-in header socket at J1 1 that allows an SF1000 serial flash card to be plugged in directly to the Prototyping board to interface with serial port b on the rabbitcore module User's manual BL2000 Asynchronous Serial Port B is not available on the bl2000, and so the following parallel-port connections are recommended instead Table 3. s1000 Connections to bl2000 SF1000 Signal BL2000 Board +5V +5V GND GND SER OUT IN10 (PB5) SER IN OUT3(PA3) Parallel SER CLK OUT2 (PA2) Port a /CS OUT1(PA1) All three bl2000 outputs need to be pulled up to +5 v with a pull-up resistor of l kQ to 2 kQ2. The following additional modifications need to be made Remove rl6l(removes GNd from J9/J11 pin 12) Install r160 (adds vCC to J9/J11 pin 12) Remove C46, C47, and C48(removes filter capacitors, which slow down the output signals) Remove C3 l(removes filter capacitor, which slows down the input signal) SF1000
