Hi, Thank you Shane for your response. I don't wan't a device mmore (FTDI -FT245, FT232). I have a PIC18F2550 with usb incccorporated and I want to see it as a COM in the PC Device Manager. I request some informations about this problem. Where I can find CDC drivers (virtual com port drivers) and so...

Thank you very much.

I have another question: have anyone of you done a project with a PIC with USB driver incorporated and if yes, I want to use a virtual com port driver and I wish if someone can tell me more about usb to rs232 emulation and drivers and where I can find this drivers.

Hi, I am working at one project that commands two current channels (coupling and uncoupling a channel) both from computer (via USB) and from board using two pushbuttons that change the status of each channel. I want to use 3 interrupts: on data received from USB, on pressing button1 INT0 and on pres...

Thank you. I simply want my uC to communicate with compulter, I think I'll use USB 2.0. I have documentated on internet and I saw an emulator FT232, which convert serial RS232 (Tx,Rx) into USB standard (D+,D-), and on the computer there is shown a com port (a serial) and Future Technology Device Int...

Hello, I want to control power (relays- to allow current, LEDs to flag), the prescription will be given from computer (C# program). My only free serial peripheral is USB, my serial RS232 is occupied. I have 2 alternatives: - purchasing a microcontroller that has an USB driver incorporated - using an...

Hello, I have some problems with port initialization on ATMEGA16: I have some examples and I seek also in the datasheet and I didn't understand what means to initialize: PORTA (or PORTB, PORTC, PORTD, doesn't matter) or DDRA (or B, C, D) with a hexadecimal value -- I know that every bit means someth...

Hello, I have a PID regulator with ATMEGA16 with two inputs: a bulb and a cpu fan. I must control them using PWM. I understand what PWM means, but i don't understand how to make space factor (pulse duty factor) to be variable, because I setonce the register OCR1A and then I don't increment it neithe...
