The touchscreen on the ChipWhisperer Pro shows various details about its status and current settings.
Screen 1: Clock
The clock screen shows the status of the CLKGEN and ADC clocks along with the frequency counter.
TODO: picture
- CLKGEN: Current frequency of CLKGEN clock in kHz
- Source: Input to CLKGEN DCM. Could be system clock or EXTCLK
- DCM: Lock status of CLKGEN DCM
- Reset DCM: Reset the CLKGEN output. Useful if clock has locked at the wrong frequency
- ADC Clock: Current ADC sampling rate in kHz
- Source: Input to ADC DCM. Could be related to CLKGEN or EXTCLK
- DCM: Lock status of ADC DCM
- Reset DCM: Reset the ADC clock output
- Frequency Counter: Current frequency measured by the frequency counter
- Source: Input to frequency counter. Could be either EXTCLK or CLKGEN
Screen 2: Routing
The routing screen shows the status of the various I/O pins.
TODO: picture
- Aux Output: Status of the aux SMA connections. Could be used as trigger input/output, glitch output, and/or clock output
- IO Pins: Status of each of the IO pins on the 20 pin connector. Possible values depend on pin
- Target Power State: Status of the 3.3 V output. Can be toggled here to reset target
- Target HS IO-Out: Signal connected to high-speed output (HS2). Could be CLKGEN, glitch module, or disabled
Screen 3: Trigger
The trigger screen shows the current settings for the trigger module and the ADC capture settings.
TODO: picture
- Trigger Pins: Whether each trigger input is enabled. Active inputs are highlighted
- Mode: Trigger combination method. Could be AND, OR, or NAND
- Trigger Source: The trigger type in use. Active trigger module is highlighted
- State: The current output level of the trigger module
- Trigger Mode: The ADC trigger type. Active mode is highlighted
- Samples:
- Delay: Current ADC offset. This is the number of samples to wait after trigger before recording begins
- Pre: Number of pre-trigger samples to be saved
- Time: Delay, but converted into a time
- Total: Number of samples to be recorded in total
- ADC gain:
- Mode: Amplification type. Either low or high
- Setting: Low noise amplifier gain level
Screen 4: Glitch
The glitch screen shows the current settings for the glitch module.
TODO: picture
- Clock Src: Input to the glitch module's clock. Active clock is highlighted
- DCM: Lock status of the glitch module's DCM
- Glitch Setup:
- Width: Duty cycle of glitch pulse, as a fraction of one period
- Fine: Adjustment on width
- Offset: Distance between clock rising edge and glitch pulse rising edge, as a fraction of one period
- Fine: Adjustment on offset
- View: Schematic of glitch clock. Shows regular clock above (blue) and glitch module output below (black)
- Trigger Src: Input for glitch module. Active source is highlighted
- Trigger Setup:
- Trigger: Cause a manual trigger. Has no effect unless trigger source is set to Manual
- Offset: Number of cycles to wait before starting glitch pulses
- Repeat: Number of consecutive pulses to generate
- Output Status
- VCC: Status of glitching MOSFETs. Shows warning sign if VCC glitching is enabled
- Cnt: Total number of glitch pulses generated
