Hi Martin

Thanks for your solution to solve my problem. So it seems no future request but it was already realized.

Kind regards

When using LCD, mostly PrintNumber and PrintString are used. PrintNumber is no problem, but to use PrintString one has always to scroll down the menu first. Can the windows be a little bit larger, so PrintString can directly be choosen?
Kind regards

Decreasing the length of the ICSP cable from about 30 cm to 10 cm solved most of the problems.

Ben and Martin thanks for helping.

Dear Derrihj Voeding microchip.jpg This is about the setup. Start with C1=10µF, C2=1µF and C3=1nF. Change in VAc must give changes in the DC voltage on top of C1. Therefor excess of charge (if VAc decreases) must flow away by means of R1+2. The value of R1+2 depends on which response time you need. ...

Dear Derrihj First of all, I'm not a high voltage specialist. But your last setup will 100% sure give very dangerous fireworks. One of the diodes of the diode bridge will connect the 230AC to ground. I STRONGLY advice you to buy a transformer for 230Vac to a low voltage. It cost about 5 pounds. And ...

Dear Derrihj

You are right: The ac voltage Vt is:

Vt=V0.sin ωt.

The peak value V0 is indeed Vac x √2. And the Vtop-top= 2x V0 = Vac x 2 x √2.

Dear Derrihj I have first to give a general WARNING. Vac of 400 Volt, means Vtop-top = 400 x 2 x √2= 1131 Volt!! All components connected to this voltage must be applicable for this voltage. A second WARNING is that mostly one pin of the Vac will be grounded with the other pin at the high voltage. I...

Hi Martin

Thanks for help. mLoader detects the chip 16LF18857.

What is the next step?

Kind regards

Jan

Hi Ben,

No progress. As far as I know the program has been stored correctly into the microchip. I only get the warning message that the "flash memory not verified".

"Attachment deleted by Jan"

What to do?

Kind regards

Becasue the problem can also be a hardware problem, I made a new set up by means of a breadboard, see picture. But the same results, no green and/or red LED's are going on. I changed the flowcode that all A-ports should be going on and all C-ports. Nothing happens. 16LF18857 breadboard.jpg Remark: Y...

Hi Ben

I use 3.3 Volt as power for this microchip.

kind regards

Jab

I like to use the 16LF18857 only with 32MHz internal oscillator and MCLR pin as input pin. In the test program I just set 2 ouput pins on, but it does not work. Wrong config word? Or something else?

Kind regards

Hi Martin

You told me to use the alternative app buider http://gold.appybuilder.com/ which works better for me. Thanks a lot.

I wanted to use 2 pages/screens with 2 languages (EN and NL). Please find attached an example.

Hi Martin The START Button must wake up the microchip from the SLEEP mode. After a certian while of inactivity, the microchip will go in the SLEEP mode. 1) If the START button will not been touched, will there any Rx signal on the UART from the bluetooth? 2) If negative, will a Rx signal on UART wak...

The breadboard is available at viewtopic.php?f=3&t=20937

Please find a breadboard for 18-pins microchips, like PIC16(L)F1847 with a subD9 female connector as used in the E-Block EB006 multiporgrammer. Power supply is placed at the left side. A 16 pins connector, next to the microchip, is available for a LCD. Breadboard_V22a_t.jpg See details in the Word d...

Hi Martin

IT WORKS WONDERFUL !!!!!!!!

I'm very happy with it.
I used the PICLF1847 which has been powered with 3V3. No voltage change problems.
Now I will start understanding to develop the MIT files. Thanks for the .aia file.

Kind regards

Jan

Hi Martin The installation is succesfull. The problem is that I started with the app "Computer", which is the android equivalent of windows explorer. Clicking on the .apk file does not install this file. Then I used the app "File Manager" and click on the .apk file succeed in installation of the UPF...

Hi Martin

I copied the apk file to the cell phone in the download directory. Clicking on this file results in a pop-up saying that Google does not know this extension and installed a text editor. How do I get started your app?

Kind regards

Jan

Hi Martin I understand the flowcode. Although I wanted the other way round, the string from the microchip to the cell phone and the start puls from the cell phone to the microchip (to get it out of the sleep mode). The other zip file is not clear to me. Is it correct that you use the MIT App invento...

Hi Martin, This is the setup of the screen of the cell phone. Mobieltje_Setup_V2.jpg The top "UPF"is just a fixed text. The 1024 is the variable (16bits) send by the microchip. And the "Start" buttom must start a microchip process. Perhaps later on, the viarable will be a string instead of an intege...

Hi Martin,

That is good news!

In the first setup I intend to send one variable to the cell phone (in Dutch we call it "mobieltje"= little mobiel) and I need one button on the cell phone to start a process in the microchip. Is this the information you need?

Kind regards

Jan

Hi Martin

I just bought 2x HC-06 modules. But, in contrast to the HC-05 module, these HC-06 are only bluetooth slaves. Is that correct for your setup?

Kind Regards

Jan

I tried it first on my Laptop (see messages above) and now on my PC. A different error message, but with the same result. On this moment I will stop using the PICkit 3. All of you, thanks for helping

Hi Martin and QMESAR,

Probably to due an newer version of MPLAB, the directory is now: Kind regards
