The byte sniffed on the MOSI pin is displayed as a HEX formatted value, the byte sniffed on the MISO pin is inside the (). The SPI sniffer can read all traffic, or filter by the state of the CS pin. The byte sniffed on the MISO pin is displayed inside (). SPI CS pin transitions are represented by the normal Bus Pirate syntax.
It follows the configuration settings you entered for SPI mode. The SPI sniffer is implemented in hardware and should work up to 10MHz. Use open drain/open collector output types with pull-up resistors for multi-voltage interfacing. Output type – open drain/open collector (high=Hi-Z, low=ground), normal (high=3.3volts, low=ground). Output clock edge – idle to active, active to idle. SPI bus sniffer with configurable CS filter. Any combination is fine, no delimiter is required between non-number values. Any number not preceded by 0x, 0h, or 0b is interpreted as a decimal value. A-F can be lower-case or capital letters. Format is 0b00000000 for a byte, but partial bytes are also fine: 0b1001. Read one byte by sending dummy byte (0xff). (v1+ hardware only).ĬS active (low), show the SPI read byte after every write. Measure voltage on the ADC pin (v1+ hardware only).Ĭapital ‘W’ enables the on-board power supplies. sets aux to input (high impedance mode) and reads the pin value. Capital “A” sets AUX high, small “a” sets to ground. Pull-up resistors: required for open drain output mode (2K – 10K). Output type: 3.3volt normal, or open collector ( pull-up resistors required). See the latest version in the documentation wiki.Ĭonnections: four pins (MOSI/MISO/CLOCK/CS) and ground.
