free rtos for lpc2378
Hi !
There are several questions you must answer before do anything with USB PC sw...
1) What is your OS for lpc2378 if any ? If you use FreeRTOS there is a nice port of it in yahoo LPC2000 group with source code, manuals etc... I have uploaded there such port with custom USB driver included for lpc2368, but as far as I know that is not a problem...
2) If none OS - you can use USB driver from LPC2000 and port it easy to your project.
3) What kind of driver do you need ? USB.org defines several device classes for which Windows provide standard driver. (for example CDC device driver for serial ports). If you can use such driver for your project - then simply add it in device and access device from PC with build in function. I'm not falimiar with VB but in C# there is ComPort class for example... SO you
don't need to write any PC USB driver !!! Also what is requireed transfer ? Bulk, Isohronous, Interrupt or Control ?
4) If you prefer to use custom driver - then write your own ... Such driver is existing in LPC200o FreeRTOS port... about PC dll and driver - if you plan to use such driver , let me know and I'll post some details about it , BUT I strongly recommend you to use some driver providedby Windows.
Regards !
5) Finally here is a sample driver for USB (in attachments)...
