Hi Ben, I changed the files and I just get 1 error now, it seems that the compiler doesen't support the extended functions on the chip, as far as fancy work on the oled goes I was just looking for a smaller display to display text rather than the great big i2c 20x4 lcd display, I am just experimenti...

Hi Ben,

I have a few pic18f24J11 devices so I swapped to these, when I try and write to Hex I get this error:
Not sure what this means.....

Thanks
Stuart

Hi Ben,

The Error messages talk of DRAM but in the data sheet for the device it has SRAM and Data Eeprom so which one is it referring to
Thanks
Stuart

Hi Ben,

Are you saying that I can use the component but I need to change to a device that has a larger amount of memory ?

cheers
Stuart

Hi, I have bought some oled displays that are i2c SSD1306: Bang_Oled.png Should I be able to use these with the gLCD_SSD1306_i2c1 component ?, only I have put a simple chart togethor with a pic16f1824 and when I try and compile to the chip I get this error: oled_fault.png Could this be that my devic...

Hi Steve,

That's brilliant thanks.

Stuart

Hi Steve,

So what you are saying is use the 5v out from the microcontroller to switch the negative side of a 12 volt circuit switching the relay instead of switching the negative side of a 5 volts switching the relay ?

thanks
Stuart

Hi, I am trying to build a simple power supply for a diy project, it consists of an i2c 4 x 20 display, a pic 16f1824 and a 5 volt songle relay, I have built an LM2567 -5 3amp 5v supply which I can run off a 12 volt battery detailed here: http://www.ti.com/lit/ds/symlink/lm2576.pdf and attached it t...

Thanks Jac,

It's programming now, I will export the FCF file now and save it.....

Thanks for all your help
Stuart

Hi,

I have just copied and pasted the info instead of typing it and I must of had another mistake somewhere, it now attempts to program but now says its an invalid device so I will delve further.

thanks again
Stuart

Hi Jac,

Well spotted after I changed it, it then compiled to Hex, but when I try to compile to chip it says that it can't find the Hex file:
Thanks
Stuart

Hi Ben,

Thanks for the info, I have my Compiler, Linker, and Programmer details as you have except my version of mplab_ipe is the latest 4.05,

Before I get to prgramming I can't even compile to Hex as I get this error:
Thanks
Stuart

Hi ETS, Yes even if I just click on compile to Hex I get: Launching the compiler... C:\Program Files (x86)\Flowcode 7\compilers\pic\bin\xc8.exe -v -t PIC16F1824 "dorgard_tester.c" (902) no chip name specified; use "PICC --CHIPINFO" to see available chip names (908) exit status = ...

Hi,

I seem to be going round in circles following different threads, does anyone have a working FCF file for a Pikit3 using MPLAB 8, Pic I would be very grateful

thanks
Stuart

P.S. Are there any other Pic icsp programmers available yet that are easy to work with ?

Hi,

After changing the Path to the MPLAB compiler xc8.exe I get the following error as if something is not telling it what the pic chip type is:
thanks
Stuart

Hi,

Sorry I am a little rusty, it looks like the compiler Path should be:

C:\Program Files (x86)\Flowcode 7\compilers\pic\bin\xc8.exe

I will give this a go and let you know how I go on

cheers
Stuart

Hi, I have just setup my Pikit3 for use with Flowcode7 via Martins guide, however when I try to program a chip with it, it says it can't find the Path, now the Path in question is C:/Program Files (x86)/Flowcode7/compilers/pic/boostc but if I look for this in the file explorer then when I get to the...

Hi guys,

Happy New Year to you all, and a belated Merry Christmas, hope you all had a great time and received lots of pressies.

Stuart

Hi,

The price of these seems to of gone crazy, the ones in Kersings link are no longer available and others are trending around £8.00 each and they have no aerial connector on them, I think there are other options available now, and maybe in time the price will come down.

Thanks
Stuart

Hi guys, I have just installed a new anti virus software ie Bitdefender Internet security, after installation a scan was done and a message came up saying that mloader was a virus, I have searched this section for antivirus but nothing came up, not sure if you are aware of this ? flow_virus.png Than...

Hi QMESAR, Yes the Raspbian Jessie image is very good now as it has a lot of previous add on's already installed such as Mosquitto server, Node-Red and so on, so it saves a lot of time, linux basics are easy to pick up, I will say learn how the file system works as it is a bit different to dos and w...

Hi,

Maybe a component for Christmas Ben

Thanks
Stuart

Hi Ben, It seems as if it is a guessing game as to when these boards will be on sale, I think it is a case of they will be openly available when it happens, so hopefully soon. I am currently using the Wemos D1 mini pro which has an Arial socket to send temperature data via mqtt, it would be nice to ...

Hi Ben, I have working examples on the Arduino IDE software but as you know it uses libraries so it doesn't give much away, most people have abandoned the programming the esp8266-01 in Lua, node MCU in favor of using C++ in Eclipse because of the lack of memory on the board, maybe things will improv...

Hi, If I had a variable with say temperature data in it, how would I connect to a local Mosquitto MQTT server and publish a topic with the temperature data, would it be a case of using the send string command with all of the required data in the preferred protocol ? EDIT: Also is there a way of acce...
