Hello. FT232 converts RS232 devices to USB devices, you need USB to RS232 for your keyboard (USB host).

Interesting question. I can't find anything about it. However, i think that you can change the freq at any time without reset the pwm or change duty cycle. With hpwm command seems to work

Hello, Is software problem or hardware proble?

If its in software, you need to use TRIS command to select input or output on a pin and config directives like internal or external osc, mclr, etc.

Hello. You can use 18f4520/18f2520 if you dont have special requirements. However, take a look to the microchip site.

a) Hi, i think that you cant use ic-prog with Win XP, however, you can program the 18f452 with ic-prog and your programmer (maybe jdm) on window 98.

b) yes, you can program it with the crystal...

Just one time




Import .hex file and check configuration fuses

Hello. Invert TX and RX on PIC side.

Hello, the links doesn't work, use [code ] Link [/code ] (withous spaces) for any url

Check the configuration fuses, mclr, internal or external osc, etc:



@ DEVICE pic16F648a, INTRC_OSC_NOCLKOUT
' System Clock Options (HS_OSC, INTRC_OSC, INTRC_OSC_NOCLKOUT)
@ DEVICE...

Hello, try with this modified code:



DEFINE OSC 4 'Change it for your osc
DEFINE ADC_CLOCK 3
steps var word
stepArray var byte(4)
x var byte

Hello, try with this code:
b0 var byte

Main:

... some code
b0=123
gosub test
...some code
goto Main

Hello, you need to configure the ADCON1 register, refer to datasheet page 228.

Hello, PicBasic doesn't support dsPIC's. But you can download a student version of MPLAB C compiller for dsPIC's and the datasheet in Microchip website.

Hello, you need to use DEC command, for example:

b0 var byte

b0=100

loop:
LCDOut $fe, 1
LCDOut "LCD TEST" 'Display line1
LCDOut $fe, $c0 'Move to line 2

Hello.

You need to use external oscillator on OSC1 and 2, or add this line to your code:

@ __CONFIG _CONFIG1H, _OSC_INTIO67_1H

This instruction configure your pic with the internal...

Hello, take a look at this link

Hi. Why a microcontroller? With a comparator and a few components can solve this problem.
It's very easy and cheaper

You need to add DEFINE OSC 4, try with HPWM command.

Hello. You need to program RA5/MCLR as I/O port and add diodes between pic and optocouplers. Connect a 10uF cap to the out of 7805 regulator. Try it.

Download Microcode Studio 3.0

Hello Rytech, your code is ok, i tried to compile it and it works. Probably you need a newer version of pbp or microcode studio.

Thanks for the info.

Hello. Does anyone know how to use 10-bits HPWM? I need an example.

Thanks in advance

Take a look on the USBMOUSE example in PicBasic Pro.

Interesting, thanks a lot
