Devices HID by definition slow — bytes per one second. Q3 Install a terminal program. Your site is great! What is the capacitance of the ‘breadboard’ you are using – there are lots of things described as ‘breadboard’, ranging from ‘strip-board’, through push in contact boards. Hi Steve, with which kind of compiler have you build your firmware? Due to copyright restrictions I cannot share the source code for these header files.

I heard it is only in ideal cases. Please who can help me? On the standard board layout, and a unit with say 5 contacts per row, if you are ‘lucky’, you get say 10pF between the rows, but on some cheap units, the capacitance can already be as high as pF, before you plug xcs in.

The warnings about interrupts being disabled, are because a couple of things in the library call code inside and outside interrupts. I therefrom also have loaded it.


I kind of know what the problem is. I used the no-bootload-hex-version.

Please send my the compiled hex file. Hi, i would like to know regarding usb communication part 2 MPLab IDE in the code written in this page there seems to be missing lbraries like include include include include. Just enter a text which will identify the connection, e. Fri Dec 24, 7: Full Circuit The source and firmware for the circuit can be found at the bottom of the page.


Fri Jan 07, 8: You can find the RS module here. What is the capacitance of the ‘breadboard’ you are using – there are lots of things described as ‘breadboard’, ranging from ‘strip-board’, through push in contact boards. In addition, the firmware now allows the user to access the AN0-AN4 analog pid18f4550 for monitoring demp data acquisition. I suppose it is answer to my question “unable to recognize device” problem because unfortunately im using t 4Mhz crystal oscillator with exact 27pF caps.


Lets say i connect pic to a Win7 64bit PC. It hides all the register settings for the user. Please do not post bug Reports on this forum. Does anyone know what else needs to be done? I have looked over the entire device and cannot find what might be the problem. If I want to use one that is 8MHz: I look forward to hearing how you modified the source code.

I make one of this wonderful device and i can say it is briliant, but i have a question for Steve. Any away have you some other code than make the ADC read more in real time, i mean faster with out stoping. To be deo, this project is slower than I would like.


USB HID Communication using PIC (Part-2) – Embedded Laboratory

Perfectly OK, since the routines involved are short. PIC receives data and sends it back. What is the specified loading capacitance for your crystal?. Your crystal, then sees a loading already present, of the strip to strip capacitance of the board, and with the supply pin adjacent to one crystal pin, and dcs pin on the other side, ub a TTL source, that is also effectively connected to DC, You get the formula coming as: To be able to see the data transmitted from the Microcontroller and to send data to the Microcontroller we have to run a terminal program on the PC.

So I will have 48MHz so full speed. Program SnoopyPro shows, that after reception of descriptors the stop occurs on 7 and 8 segments I shall try to result a copy of the report here: For non-bootloader operation I comment out: I know VB and I can build one very simple form for direct control, so I think that the other will agree with me.
