| + | When the Digispark powers up the LCD should light up right away and show some dark boxes on the top line for about 5 seconds. If it lights up but there are no dark boxes try adjusting the contrast - the blue box with the phillips head thing on the back of the screen. | ||
| + | |||
| + | After 5 seconds the boxes should disappear and say Digispark! (if using the BasicUsage LCD example) instead - if they aren't disappearing this could also be a contrast issue - try adjusting it the other direction. | ||
