Thanks to Chipfrier 27 and mnfisher
quite a bit of info to trawl through so give me a day or two and if no response Ill be in the phsyc ward.
ps I live in New Zealand so is you guys are in the UK or europe then we are 12 hours appart
cheers

Thank you Chipfrier27
Yes I know it is hardware related as the arduino sketch works. The question is how do I switch on the pullup facility and set the port (bit) direction, as I previously stated I believe the arduino Library is setting the conditions that the keypad needs to operate, but no sign ...

Nothing appears in the display using the FC code, and I assume the ports need setting for pullup and direction etc.
I thought FC would have done that simply by adding the keypad ? but maybe not
The code works fine in simulation, but I wanted to ensure the hardware worked before writing lots of code ...

I uploaded the FC file here:-

and the Arduino sketch listing which I used to prove the hardware was connected properly

The flowcode sketch is quite simple, wait for a key press, read ...

I put together a simple keypad and I2c display to test the flowcode I am going to use to get input from the user. Whilst the display is ok, the kaypad dows not work. I double checked the hardware connections and eventually wired the keypad to different pins, no go!

I looked on Arduino website and ...

Thanks for the info Mnfisher, the two boards I have are looking duff, so for the project I am doing I am switching to ESP32-C

I have a project which uses an Arduino pro mini (328P uP), and I2C display and a 3x4 keypad.
The keypad fails to work and I note one of the Column pins is always low. Looks like I need to turn on the pull up resisters, but my attempts at using C code cause an error which prevents me from compiling ...

OK, the LCD not working was due to selecting the GROVE I2C display from the options given. My code had the correct address and my scope showed clock and data present, yet the display showed nothing. Long time back I remember making the same error when programming in the early days a 16F type pic and ...

Solved. well the programming bit is solved.
Having bought a Arduino Pro-Mini with 5v 16Mhz clock, and a 328 chip. in the flowcode system I selected the Arduino pro mini 5v 16mhz and did not check to see what processor that had embedded. When I finally figured this out I noted that the selected ...

Hi all
I have used the flow code system for a while but never on Arduino before. I wanted to shorten a project and chose the 5v pro mini module.
My project would not compile to target, so I also wrote a simple test project which would also not compile to target.

I switched to the Arduino programing ...
