Re: MX022 - Dual Channel Temperature Logger

Hi to all,
I have tried the Remote Tx on hardware, but am getting high swing readings on the display. Increasing the delay doesn't help. The voltage on the adc seem constant eneough. I have all my power connections decoupled.

Re: Communicating with a PC

Hi Martin, You always come to my rescue. Appreciate it man. It always happens when I change chips, I forget to check the config. I got it working now. Thank you. I'm still not clear on the flow control setting. As I mentioned in previous post, I'm using a Prolific usb-serial cable. When I tested the...

Re: Communicating with a PC

Hi Ben, I continued working on the problem and was able to do the test using the hex file provided for the EB039. It works with my Prolific usb to rs232 cable connected to a max232 level converter. I have to use a specific terminal program though. If I try to use Hyperterminal, I can send, but the f...

Re: Communicating with a PC

Hi Ben,
I've used the test programs from the site and change the xtal to 20MHz. When I connect the hardware, I received garbage on the port and am not displaying anything on the lcd when sending. Did I fry my pic?

Re: Communicating with a PC

Hi Ben,
I'm stomp on making my rs232 test programs to work on hardware. I don't have the EB039 and I got a usb to serial cable. Wired in a max232 circuit between cable and pic, but I can't get it to work.

Re: Can't get Flowcode5 to work with Pickit3

I was looking for the right place to post this but I guess this is as good a place as any. I run into some problem a week ago after I used the stand-alone application for Pickit3 to program a chip directly. After doing so, I lost the interface with Flowcode 5. After re-checking all the parameters, I...

Re: More advanced LCD Four Digit Door Lock.

Hi Martin,

Did a unicode version using Lock_State variable. The simulation works, but then I realized you usually turn-off the alarm when you are already inside. How do you implement an entry delay? This is turning out to be a full-pledge home alarm system. Appreciate your comments. Cheers.....dan

Re: More advanced LCD Four Digit Door Lock.

Hi Martin,

Thanks a million. That was the routine that I couldn't figure out where to insert. I was also thinking in bed last night why do I need two pass codes? Most alarm systems only use one. Will try with an output variable and a decision to check on or off state. Thanks again.

Dan

Re: More advanced LCD Four Digit Door Lock.

Got back on the project and added a lock/unlocked routine. Works, but I got lost in the change_code portion. I can make the change in the lock code, but I need help on the unlocked code change. I figured this program can be used for alarm circuits also. Any ideas appreciated.

Re: More advanced LCD Four Digit Door Lock.

never had the problem with keypads. it gets pretty dry here in winter and i always have the habit of grounding myself before touching anything metallic. then again keypads have plastic keys and there is usually a rubber membrane before the actual contact. don't know how much they are rated though.

Re: More advanced LCD Four Digit Door Lock.

Hi all, I've been using this example to learn Flowcode, tried some modifications. I wanted the lock to have a limit of tries. I've changed the wrong_tries to not exceed 4. I've inserted a reset_macro on the code_check macro to display "YOU HAVE EXCEEDED NUMBER OF TRIES" and to jump to end ...
