|
|
Attached to this message is the LCD driver I wrote for the Handyboard written using ICC11. Feel free to use it. Some notes on it: The driver is designed to operate asynchronously.

I was wondering if anyone knows where I could purchase the Sharp Is1U60 IR detector. I have looked for it, however none of the distributors I have checked with even carry it. I tried Digikey, Mouser Electronics, JDR, Jameco, BG Micro, and others. (...) (26 years ago, 3-May-98, to lugnet.robotics.handyboard)

| | MODB - How Is Expanded Mode Entered
|
|
If MODB pin is always grounded, how does the MCU get into expanded mode to access the 32K SRAM? The data sheet shows MODB HIGH to enter expanded mode. It show MODB LOW to enter single chip mode.

Please forgive this probably silly question; as a software person I only dabble in hardware as a hobby: I want to make my own little expansion board and it requires signals from the expansion connectors of the HandyBoard. In particular I want to run (...) (26 years ago, 2-May-98, to lugnet.robotics.handyboard)

|
|
My problem turned out to be with Win 95. If I boot to DOS the PCBUG11 program works fine. It fails to work when working from a DOS window. I can now communicate with the MCU so my RS232 must be fine. When working from the command line in PCBUG, I (...) (26 years ago, 2-May-98, to lugnet.robotics.handyboard)

| | Testing with PCBUG11
|
|
I have assembled the HandyBoard up to the point of adding the SRAM. I am still waiting for my SRAM to arrive. But, I want to check out as much as possible. Every step checked out fine to this point. I have two options at this point. I have an 6264 (...) (26 years ago, 2-May-98, to lugnet.robotics.handyboard)
