Using Flowcode, How would I tell RA0 port to activate on logic low instead of default logic Hi. I have a working flowcode I have the circuit built. but the input ports only work active hi. But I require the input switches to pull down ie logic low to activate my selected output ports. Thank for any ...

How far can these units transmit utilising the lower layer of irda protocols? I understand that when using the mcp2150 part of the EB 012 configured for higher level of irda protocols, only 1 Metre communication can be achieved to enable PDA, Mobile phone type devices. But when utilising the MCP2120...

Thanks Steve for your swift reply,
I have already tried this and the PIC16F88 does work ok with flashing LED program.
It is the same when PIC16F628 is used also
It is only when RS232 Macros and UART mode are involved in the programme that I can't get INTRC to work?

I have my fully fledged project up and running with my RS232 peripheral. I have built a circuit incorporating PIC16f88 and MAX232 chips with extra components ie switches, crystal, resitors, capapicors, regulator etc. I have tried programming my pic chip so that it would run on the internal oscilator...

The reason why my Pic16F88 on assembling came up with mesage was resolved by updating the h file within C2C folder. I managed to get the Pic16F628 and the above chip to work with my project by linking the corresponding Screw terminal connectors for port B to the relavent jumper link on the rs232 E-B...

I am progressing very well with my rs232 project using the PIC16F877A and can now send various rs 232 byte commands from several push button commands on input ports of the chip. It will also work with PIC16F876A. However IT will not work with either PIC16F88 or with PIC16f628 I am making sure that a...

At last I can now communicate to my external non PC peripheral device via rs232 thanks to JIM. I purchased the new version of the pic programming development board and the rs232 E-BLOCK and followed Jims FLOWCODE instructions using a Pic16f877A and all worked ok. Three more questions if I may? 1:-Wh...

I have been experimenting with tut06 that came with sample Flow Code. How do I generate a Flow code so that I can create a D type Flip Flop circuit i.e when a switch has momentarily made contact on Port A Ra0 for example, how can the Led on Port B rb0 be made to remain lit instead of going out when ...

Thanks for your reply, I can`t attatch an rs232 object to the program line , I only have LEDs, LED7seg10, a thermometer symbol, LCD display, switches and LED7seg40 as object atatchments. Am I missing something? I am running flowcode V1.0 on a version 2 pic micro development board and currently exper...

Thanks for your reply Steve, Since the last time I have been doing a lot of researching and acted on your advise. I built a circuit board containing Pic16f625and a max232 rs232 interface chip and several capcitors and 5v regulator circuit. ( This is not too difficult for me as I am a service enginee...

I have pic micro development board v2 and trying to use flowcode to build project. I can use flowcode for simple LED flashing projects and delay switching etc but I am having difficuly in programming chips ie pic16f628 to communicate to an rs232 peripheral device (not a pc). I need to transmit 4 byt...
