Hi folks, particularly programmers and would-be engineers, Out of curiosity, I asked HIMS (at the Korean HIMS bulletin board) a few technical questions. The questions and answers are as follows:
Q. Is it possible to use serial port to send debug information to a computer monitor? No answer from HIMS. Q. It seems that IEEE 802.11N is gaining in popularity; is there plans to implement support for this standard? HIMS: Braille Sense only supports 802.11G standard at this time. Q. Does the SD host controller (SD slot) on the Plus, Plus QWERTY and Voice Sense support SDHC (SD High Capacity) cards? HIMS: Yes. Q. What is the display resolution for the LCD monitor on the BS unit? HIMS: 200X40. Q. Under Windows CE 5.0, one can use up to 32 MB of virtual memory and execute up to 32 programs. Does that explain why one can run up to seven programs simultaneously? No answer from HIMS. Q? Braille Sense app image: are all programs grouped under a single Braille Sense application image or are they separate executables? HIMS: Each of the programs under Program Menu are separate executables. Q. besides main BS program and CE kernel (nk.exe), what processes start when BS boots up? HIMS: When Windows CE boots up, the Task Manager application starts. All BS programs run as executables under this main Task Manager program. *1 Q. What program language was used to create BS app, and is the SDK language the same, or is there an interpreter or some sort for other programming languages under the SDK? HIMS: Braille Sense source code was written using MFC (Microsoft Foundation Classes) *2 Notes: *1. So, the Program Menu under Braille Sense is named Task Manager. Thus, under this interface, the executables for program on that menu runs as separate applications under TaskMan framework, like Windows Explorer shell. *2. MFC was written in C++ - this means that BS source code was written in C++ language. Hope these answers would be useful for the list. Cheers, Joseph
