Delay and Timeout Routines for HiTech C (PIC16Fx core) Example project illustrating delay and timeout routines. Unlike the routines available from the Hi‐Tech C site, these are written in in‐line assembler and thus give precise timing. Remember to match the actual microprocessor clock speed to the setting for PIC_CLK. Delay routines v7.1 for Hi‐Tech C and PIC16x core. ^ Go to top
Delay and Timeout Routines for HiTech C (PIC18Fx core) Example project illustrating delay and timeout routines. Unlike the routines available from the Hi‐Tech C site, these are written in in‐line assembler and thus give precise timing. Remember to match the actual microprocessor clock speed to the setting for PIC_CLK. Note: these routines could cause problems if Hi‐Tech C banks the assembly variables in the incorrect bank; the problem would only surface on a large project with high RAM usage.

USB Serial port on PIC18F4550 USB example for PIC18F4550. Plug your PIC18F4550 into your PC using a USB cable. A virtual RS232 COM port is created, allowing your application to print RS232 messages into HyperTerminal. Allows porting of legacy code that used RS232 comms. This project is a modified form of the CDC (Communications Class Driver) available from www.microchip.com. The www.htsoft.com forum has some discussion on this code. Note: ensure that you read "readme (including install notes).txt" after download. Schematics: this code runs on the PICDEM‐FS board from Microchip. To make your own schematic, place a PIC18F4550 on a breadboard, ensure that you are using a 20Mhz crystal, place a 470nF capacitor on port Vusb, and hook the USB directly to the chip. It should start to work straight away. Download the PICDEM‐FS datasheet for the exact schematic to use with this code. Result: start up HyperTerminal or putty, find the new COMx port that has been enumerated. Set it to 115200,N,8,1. The actual COM port speed doesn't matter, as its a virtual comm port. You will see "[alive]" being continuously generated on virtual com port X over USB. You can find the exact number of the virtual COM port by going into "Control Panel", then "System", then selecting the "Hardware" then "Device Manager", there will be a new COM port under "Ports (COM & LPT). You can change the number of the virtual comm port by going into properties, and selecting the new COM port. 11th Nov 2007 ‐ tried it on Hi‐Tech C v9.62, it worked. Had reports that it does not work on Hi‐Tech C v9.51. 2nd Feb 2009 ‐ customer got it working with Hi‐Tech C v9.51, it worked after some tweaks. Added instructions to v1.10 of the download.
