Re: HC05 HELP
Hi chipfryer right been messing with this for ages and found that the connection was wrong if i connected my usb to serial adapter to the HC05 i found i could send text via the laptop to my phone and vice versa with the baud set at 38400, i then tried the same thing with the baud set to 9600 through...
Re: HC05 HELP
hi chipfryer thanks for the update ive tried the new flowcode but still nothing ?? my phone confirms connection and paired with the HC05 but when typing led nothing ive tried upper and lower case plus it looks like the HC05 is pinging something back to me in the form of 2 green diamond shapes on my ...
Re: HC05 HELP
hi chipfryer ive been messing with flowcharts all after noon trying different things and getting no where looked all through this forum but couldnt find anything that met my needs there seems to be so little about with regards flowcode , then i spotted your post i changed the target chip to a 16f182...
Re: HC05 HELP
hi chipfryer regards TEST_INT the led does light when led typed but didnt realise if led was typed again it would toggle the port and turn the led off however when typing led for the 2nd time the led does not extinguish in the calculation box i did alter LED=NOTLED TO LED=!LED but this didnt make an...
Re: HC05 HELP
hi chipfryer ive had a quick play and left all my hardware as previous and first compiled the TEST_INT then uploaded to the chip, now from my phone when typing led the led on portA0 lights, did the same with TEST_INT2 at power up the led flashes 3 times and does nothing else even when typing led so ...
Re: HC05 HELP
hi chipfryer i have established comms with my HC05 using "cool term" terminal software and configured the bluetooth same as you, with the HC05 connected to my laptop i can connect via my phone and using serial blue tooth app i can send text from my phone to the laptop running the cool term software ...
Re: HC05 HELP
hi chipfryer
this is great and shall try in hardware although i shall use a different pic i was going to use a pic12f1840, also in the circular buffer am i right in thinking the 3,1,1 sequence that the 3 represents LED ??

hi all having clicked on the wiki link above there is only one flowchart when sending data via a keypad to the LCD, am i right in thinking that this flowchart is for the transmitting microcontroller as well as the receiving controller ?? with the transmitting HC05 set as master and the receiving HC0...

Pic To Pic Bluetooth
hi all, i have no experience of Bluetooth comms but want to start off and basically send a signal from one pic to another to light a LED using the HC-05 Modules. I've looked at the wiki and altered a program to suit my needs however i must stress that I'm guessing but I've attached the transmit pic ...

Re: TIMER 2
Hi martin ive been playing around in software, using Timer 2 i cant seem to make the mentioned calcs work so i stuck with Timer 2 and made some changes with PR2 ive attached what i did and now for 20 seconds i get 51.90 Hz and the other 20 seconds i get 40 Hz then it repeats ive attached the flowcha...
Re: TIMER 2
hi martin thanks for the reply my desired frequency is 40Hz therefore from your reply i did the following using timer 2 i set prescaler rate 1:16 postscaler 1:13 rollover 256 for nearest value to 40 is 37.560 Hz then i did preload = 256 - (8000000/4x16x40) = 3125 therefore 256 - 3125 = -2869 ??? ive...
TIMER 2
Hi all id like to know if possible if i could alter the output of timer 2 within software, i have a port toggling at 40 hz but would like to alter this frequency to say 49 hz for the first 10 seconds of operation then revert back to 40 hz, at this point frequencys are examples i realise i need to ad...

Re: DECIMAL POINT HEADACHE
hi martin i carried out your last recommendations , i changed the ref resistor to ULong and now this has perked version 2 up with a 1 Meg resistor as ref i can get down to 100k ohm with accurate results compared to a fluke but no good for low value ie 180 ohm but this accuracy comes back with the or...
