Looking at home automation on the Raspberry Pi as the Broker with MQTT and Mosquitto. I already have a small system running on CANBus using several PIC16F877A. I now would like to enhance my system and have been playing with Node Red and Pi3. However, at one point there was a MQTT Client in the Comm...

Dear Martin,
Thank you for your help to date. Done as instructed. Now get to 2 decimal places but still printing only the whole number.
Sorry, I'm not very good with string manipulations etc. Please see amended as per attached.

Can someone help with the attached. I want to be able to print an amps value in decimal to 2 decimal places?

Several months ago I downloaded the example for the HX711 and had the example running on my BLOO80 EBlocks 2 programmer. I'm trying to design a weighing device to weigh my gas bottles so I can see how much gas is left in the bottle. I acquired a load cell and connected this to the HX711 and then I d...

Dear medelec,
Thank you. I'm new to version 8. My properties panel was not set wide enough so I could only see the left column? What a plonker?
Thank you so much.

I require 2 PWM outputs from my 16F877A. I can simulate OK but the chip only outputs to PWM-1 I realize that you can assign the PWM outputs to the pins require but I just cant understand how? In properties I can highlight the pwm_pin and nothing comes up to confirm the pin? Also can expose but again...

OK, I see. Thank you very much.

Dear Benj,
Thank you. I can see where I went wrong. However, 2 Port A outputs faulty on my combo board which also led me up the garden path?
This is a new board, do I need to return, and do I need any return paperwork/code?

Thanks once again I will now get some sleep tonight.

Using BL-80 Multiprogrammer with BL114 Combo Board. Used Flowcode 5 & 6 in the past but not for about 18 months. Decided to get back to Flowcode due to recent retirement and move to Spain. Invested in Flowcode 8 and several new F8 Boards. Tried to get some of my older programs working using the new ...

Just spent last couple of hours trying to print off my Flowcode project. All help points to the printer icon on the Main Toolbar? Well on my latest up dated version their is no printer icon it's missing? I have managed to print by Ctrl + P after lot's of searching? This is pretty basic stuff and nev...

Dear Enamul, I want to send and receive data by CANBus see my original post. Say just one port on TX to one port on RX. I have this working fine using 16F877A but experience problems when turning into PCB for actual use in a project of mine. Also want to understand CAN better as this is used in lift...

Dear John, Thanks for your help. I'm using EB-006 to program with EB-017 patch board with the 2551 on it. Checking CAN with Microchip CAN Bus Analyzer. Programme will now download. However, if in the CANBus properties I check the "USE INTERNAL CAN" and attempt a download I get nothing but error afte...

Flowcode 5 Recently had occasion to use CANBus for the first time. Built TX & RX Nodes using 16F877A chips and e-block CAN module EB-18 and managed to send data from port on TX to port on RX. Tried to convert to PCB's but only had sucess with RX? I still don't know why as I've given up. To simplify...

Dear David,

Thanks, worked a treat.

Kris.

Done exactly as recommended but I still get "Flowcode V4.exe is not a valid Win32 application"?

Computer crashed with 4.3 up to date Flowcode. New computer up and running with Windows 7. Installed my version 4 straight off the CD ROM, registered and all apeared OK. However, I later realised that the version I had installed was not the latest version? I have tried in the past at installing up t...

Thanks Chap's now up and running. Some sort of driver issue even though drivers loaded from the start.
The clue was in the device manager which only showed the MIAC when trying to programme?
Highlighted MIAC searched driver from disk and rodger me with a ragman's trumpet! THANKS.

Dear Ben, Nothing else plugged in? Straight from USB to MIAC. Help files do not even mention MIAC? FAQ only 1 post. Forums not helpful. Where do I go now? I've used many PLC controllers in the past 30 years. So far this is the only one that has beat me? What about the fault code what does this tell ...

Running latest Flowcode 4.3.7.63 (already on my computer) instead of 3 which was included with th MIAC. Drivers downloaded as required. WhenI try to send program (any program) to the MIAC I always get " failed with error 997: overlapped I/O operation in progress"? This is staight out of the box? Ple...

Changed 2331 to 18F4331 with better results. I have this running in my version 3 programmer/simulator. It will count up and down but well out of sync with the QEA and QEB inputs from the encoder. Also the INDEX input has not effect on the count. The count I get is very slow and somewhat unstable as ...

Ben,

All settings as per your earlier reply regarding PIC18F2331 with clock of 19.6608MHz ?

Kris

Dear Steve, Up dated this week end to Flowecode 4.2.3.58 with PPP 3.11.15.30. Everything the exact same? I thought I would try the code to a 4331 as this was the basis of Seans original quaderature encoder. Now it will compile to the chip but does not run properly. Even the LCD display does not work...

Dear Ben,

Thanks but no different. Simple program as stated. Programming fine until the end then "programming failed <1> <2> <3> <6>
Return code 0


This is pretty much where I was but I could manage just programming failed <1>, return code 0.

Kris.

I have Flowcode 4, Development board 3 with up to date PPP. I cant run a sample program Encoder2 posted by sean on the 26th Feb 2008. Sean surgested that the program was OK but configuration could be wrong. Despite hours of trying I still can't get it to run using flowcode. However to veryfy the PIC...

Downloaded Bit Banging RS232 Data out and Data in from the Matrix examples site. Slightly changed Data out to suit 8 bits input. This seems to work spot on as with one start bit (0) 8 data bits and one stop bit (1). Had my scope on this and seems perfect. Timing also looks correct. The problems are ...
