- Open in 3D viewer
- Clock: 10 Hz
How it works
- An 8 bit lfsr powers a random number generator between 1 and 6. Psuedo random number generated using the last three bits of the lfsr.
- When the user turns the dipswitch at locaiton 0 (LSB) to on the number given on the next clock cycle is locked in as the dice roll.
- To roll a number number reset the 0 dipswitch (LSB) to off, and turn it back on again.
- When dipswitch is off dice outputs 0 to seven segment display.
- Note: if the dipswitch at locaiton 0 (LSB) is turned on at startup 0 will be returned / show on the seven segment display until it is turned off and back on again.
How to test
Test by varying timing of dipswitch 0's (LSB) input to on and off.
External hardware
Uses on board dipswitches, and 7 segment display.
