You have not clear what's an USB host and USB "client" interface.
For example, a PC has USB host connections, so it can accept USB client.
USB hosts are not trivial devices, they have capabilities to enumerate, recognize, interface and often give power to the clients.
Pen drives, printers...
The answer is simple: it's impossible.
Your "microcontroller board" should implement an USB host interface and a bluetooth stack protocol.
This is not the case.
You could think to try to find an RS232 / bluetooth interface but - as far as I know - they are not exactly cheap as the USB dongles...
ibm p200
I need the service manual or the schematic for IBM P200 display.
It's a Sony Trinitron OEM display, IBM part number 6555-7E3
OEM model should be SCC-J33C-A
The display is no more able to sync with low resolutions (e.g. while BIOS does POST) but works perfectly in hi-res modes (e.g...
pioneer ct 400
I need a service manual, schematic, or whatever for Pioneer Tape Deck CT-400
All the belts are missing (they were melted, spent an hour cleaning pulleys)...
Thanks in advance!
flush buffer mscomm
I was talking about the event driven version. You should be sure that your character processing routine gets only one char strings.
You consume only the first one, and ignore if Buffer has more inside.
ANYWAY
1) You should use Option Explicit
You declare "Evens" but in...
rthreshold mscomm
Your code must have bugs, I think.
My own code runs much faster when I rewrote it event driven, and it's the only way to go when there is a delay between enquiry and reply by the serial device.
Otherwise your code waste billion of CPU cycles.
Did you set BOTH InputLen...
mscomm inbuffercount
There are so many resources about MSComm... other the brief docs by Microsoft
Simply search by google and you will find many articles and samples on topic.
I would only remark that you should use MSComm only in an event-driven fashion, e.g. do not wait for chars arrival...
I have this component in a motor driver to be repaired.
The full markings on it are:
C832 - BHK3012TV
I was unable to find any data sheet of this device.
Any help will be appreciated.
Thanks

Re: pic chips
SphinX, I totally agree with you.
mrm, did you ever examine the assembly code generated by a decent C compiler for PIC and have you compared with the code you may write to accomplish the same task ?
You may have some nice surprise !
Last, I hate hunters ... let little birds...
I can surely exclude both cases:
1) I have implemented the command to turn on/off the heather, and if I turn it on I read the expected increment of temperature.
2) If I would have inverted MSB and LSB, reading would be totally scrambled. Also the MSB is easily recognized because it has the...
sensirion pic reading
Hi all
I have successfully interfaced an HT11 temperature & humidity sensor to a PIC, but comparing the readings with other thermometers I have always too much temperature (i.e. 25 C vs 21 C real) and too low humidity (25% vs 35% real).
I have soldered HT11 on a 8 pin...
Re: Microchip TCP/IP Stack
Just an idea ... are the configuration fuses correct ? If it's so slow, it may be due to the chip working with a much slower clock than intended one.
Another issue can be the resonator/xtal not properly working. You may check the clock frequency with a scope...
Ciao...
Re: Microchip TCP/IP Stack
Would you share schematic and other info about your work?
I about to build such a picdem clone and I will follow a proven design.
Thank in advance...

It seems you forgot to disable some analog features on your chip !
Read carefully the default state of I/O pins on datasheet, then initialize correctly them !
Cheers
