16c745

hi
i've tried an easy-to-use USB solution with OPT 16C745 (samples available )
hex file for pic given below
hidcomm with examples
VB sample code with my hex file : USB control for port direction and value (read/write)
Blink led on PORTA.0 (pin2) if timer enabled, LED ON/OFF with button if timer disabled

Dim Buffer() As Byte
-----
ReDim Buffer(6)
-----
PORTA => Buffer(0)
TRISA => Buffer(1)
PORTB => Buffer(2)
TRISB = Buffer(3)
PORTC = > Buffer(4)
TRISC => Buffer(5)

Yes this is low speed, if you need high rate transfer dont look at this USB for beginners page !
A full-speed HID can transfer up to 64,000 bytes per second (64 bytes in each 1ms frame). A low-speed device is guaranteed only 800 bytes per second (eight bytes every 10ms)
Compare low speed to RS232 @ 4800 bps

pic hid delphi code

The only problem with this example is that the PIC is OTP (only time programmable), so it mean if you try this example, you have to buy another PIC for your design. Please post one example with 18F4550 or other Flash PIC.

pic16c745 examples vb

Hi,
I am looking to convert my rs232 based pc to pic communication to USB based. I do not want to change the hardware part of the application. So would like a program on PIC usb devices to convert usb to rs232 builtin, HID type. The pc software will be modified for USB 2.0 comm.
Thanks

@samytech

PIC16c745 is a OTP (One Time Programmable), then there is no way to reprogramming it once you've downloaded your hex file.
