|

Anybody have any sample code for interrupt driven serial output. I need to send out 3 bytes and have the SCI interrupt occur after each byte. Thanks! -John (27 years ago, 10-Jun-97, to lugnet.robotics.handyboard)

I opened a mouse a while back. Although I was kinda young at that time, I believe what I saw was two incremental quadrature encoders (from what I remeber visually). One encoder is for the X axis and one for rhe Y axis. The mouse I opened had slotted (...) (27 years ago, 10-Jun-97, to lugnet.robotics.handyboard)

| | Dissecting a mouse for the Handyboard
|

Hi All, Has anyone dissected a PC Mouse, and interfaced it with the Handyboard, to use it as a directional and speed indicator. Any information on how the mouse works or how it can be used with the handyboard would be appreciated. Thanks Michael (27 years ago, 10-Jun-97, to lugnet.robotics.handyboard)

Try going to the shutdown menu for Win95. Select restart in Msdos mode. Once the system gives you the dos prompt, try hbdl again.

I'm unfamiliar with the workings of IC, but if your interrupt service routine is sufficiently short, and you don't reset the interrupt mask to enable recursive interrupts, you shouldn't notice the difference.
