| | Re: Wireless Handyboard Link ?
|
|
I obtained the RF wireless kit ( HP Series ) from Lynx Technologies a while ago, and I have not had any success yet. My guess is that the handyboard is unable to "Synchronize with the board" with the half- duplex communication provided by the kit. I (...) (28 years ago, 13-Jan-99, to lugnet.robotics.handyboard)

| | GP2D02 Interface Question?
|
|
Attached below is IC code for a GP2D02 rangefinder. This is a slightly enhanced version of code from Bjorn Astrand. My question relates to the use of TMSK1 in the code. From reading various M69HC11 documents, I think (???) that I know what bits are (...) (28 years ago, 13-Jan-99, to lugnet.robotics.handyboard)

| | Re: motor ports
|

Russell, Just a suggestion from experience. Before you invest a lot of time developing hardware to expand the capability of the Handy Board, I suggest you write the program. Just "stub out" the motors you don't have with dummy subroutines, or for (...) (28 years ago, 13-Jan-99, to lugnet.robotics.handyboard)

| | Generic expansion board?
|
|
Has anyone ever created a generic expansion board for the HandyBoard? What I mean by generic, is a board with say a .10 grid hole pattern and some power and ground traces . A board or boards like this with custom circuitry, could be stacked on top (...) (28 years ago, 13-Jan-99, to lugnet.robotics.handyboard)

| | The Onboard memory Circuit
|
|
I have some questions about the handyboard memory: 1) Does it matter if i use a 70ns Eprom instead of the 100ns one? 2) Can you use EEproms or FlashRoms instead of the Eprom ? 3) Can i use more memory than the 256 KB ? And is there a exchange (...) (28 years ago, 12-Jan-99, to lugnet.robotics.handyboard)

| | RE: Motor Ports
|
|
Russ, This would not suffice. The PCODE would need to be changed as well. The end result of the motor interface routines in C in LIB_HB.C is that RAM locations 0x0E, and 0x22-0x25 have the direction and speed pattern info for each of the four (...)

| | Re: UCOS
|
|
I'm also very interested in using UCOS in HB. IC is very slow and have very stupid multitasking. Until now I find only basic HB library for ICC11 ((URL) library is at ftp://ftp.imagecraft.../libhb.zip It may by usable with UCOS. ===...=== Andrew (...)
