Does anyone know of / have / could write (cheeky!) a simple example program to allow say a set of leds (why always a set of leds?) to be turned on off from the PC with the PIC connected via USB? I have it working using serial, in fact that was one of my first projects, but with USB it seems I need something a bit more clever on the PC end than just hyperterminal.......... Thats where I'm a...

Hi. Well, after getting my new PIC, it didn't take long to get it going! Was a little worried at first! I can now receive using USART and then using the values taken put that in the PWM unit and there i have a dimming LED! Beats having a DA and few Op-amps! My question is about the PWM maths. I have read the datasheet but can't figure out how to calculate the frequency of the PWM. Maybe caus...

Hi All: I have a Pic16F628 chip which I want to be able to communicate with my PC via a RS-485 line. I want to use the USART on the chip and a DS75176 Transceiver in a Half Duplex setup, but my problem is with what to control the Read Enable or Transmit Enable pin on the DS75176? If anyone also has a simple schematic and code that they don't mind sharing I would be grateful. Regards ...

Attempting to troubleshoot problem with usart, asynchronous mode, for a school project. Two 16F877. Using the ICD-2 in circuit debugger. We believe our transmit chip is working but we can't get receive to function correctly. We know interupts will not work while Single stepping in debug mode, but in animate mode interupts should function, correct? How close do the clocks have to be? ...

Hi all, I am using C18 complier to program PIC18F452 microcontroller to display data on a LCD display module (Hyundai Korea - HB16202-A). The microcontroller is connected with an external oscillator SG531P, and giving it a frequency of 40MHz. The problem that i encounter is that, i am not able to display any information or character. I wonder whether is it the oscillator thats causing ...

Building a controller to output pulses to steppermotor driver. What is the recommended pulse width output? Is there a standard ( one length fix all) or is there other factors I need to consider? Such as the driver itself or what is specified in the motor datasheet? I see in the motor datasheet headings Resistance, Inductance. Is this something I need to consider? I'd appreciate any adv...

Hi Has anyone done a single/two channel or more Remote controller codec using some variant of C (HiTec C/CCS C etc). Based on RC5 would make it more useful. I want to control the IR Remote controlled devices in my house controlled through a single PIC. I have seen lots of ideas on the net, but they recorded the data streams from the original remote and played it back. I want the P...

For example you can get free C/C++ ...
