'GoPOP' a System80 pop bumber driver
This will replace your old System80 Pop Bumper Driver Boards (PBDB) and give you the opportunity to add These devices to your System1 game. It comes with LEDs to control 5 Volt and Solenoid power, a test button and with adjustment for pulse-time easily done by jumpering.
Find below all Information you need to produce this. If you do not have a PIC programmer by hand, you may also want to have a look to one at my other projects and make a PIC programmer too.
The pulse time for the bumper solenoid (standard without jumpers is 40ms) can be adjusted by the first five jumpers. You can use multiple jumpers while the pulse time setting is 'additional' to the default pulse time. So the range you can set is between 75ms and 25ms. -> ( (40+20+10+5 ) and (40 -10 - 5) )
The last three jumpers (debounce) are not used and will be removed in next HW revision. With latest software version the bumper is only activated with a 'falling edge'. So if your switch get stucked, with GoPOP you will only have 'one pulse'.
difference PCB v1.0 & v1.2
Hardware v1.2 has only one connection in addition compared to v1.0.
If you want to use 'LVP Mode' version with v1.0 connect pin7 of the PIC to GND (see picture below).
LVP mode version of the software can be programmed with my pic programmer.
