Looks like RPI_CAL_String.c is missing the FCLsz_TEMPSTR fix and other updates - one for Ben

I've not had chance to check your zip yet.
But have you tried a full database update?
The CAL string files have had some changes recently.

Your program looks OK. But we need to check that: a) the program is compiling OK on your machine, b) The device is being programmed correctly. The Flowcode Compiler Messages window will give you the answers to those questions. This output is also saved to the file button_pico.msg.txt So it would hel...

FCLsz_TEMPSTR is undefined in PICO_CAL_String.c
this needs a fix from Matrix

I can’t help much further, I don’t have v8 or a STM32F469I disco board, only other thoughts are:
• Does it work OK in Flowcode simulation?
• What does a simple Initialise and print Hello World do?
• Try Flowcode V11?
• Maybe Matrix have a STM32F469I discovery board to test?

Strange that the longer delay fixes the issue. The Flowcode display component uses the STM display driver library, so I think it's less likely to be a software issue. How is the power supply? If using USB, is it a good quality cable? Anything else connected to the board? Do you have another Disco' b...

To use 8MHz crystal and maximum allowed clock rates here are suggested settings clocks.jpg settings.jpg The Flowcode Timer interrupt dialog calculations are incorrect for STM devices (Flowcode does not know about multiple clocks) Therefore you need to work out yourself the prescaler and roll over va...

Have you downloaded and installed the FC11 PIC toolchain from Matrix website?
Ah, edit, I've just looked at your new msg.txt and see that you now have correct compiler.
Must be something else wrong.
Have you done a full component update?

You seem to be running an old version of XC8 (V1.45) Looks like your PIC compiler path is "C:\Program Files (x86)\Flowcode\Compilers\pic\" This would normally be "C:\Program Files (x86)\Flowcode\Common\Compilers\picv2\" Please check toolchain location in Global Settings->Location...
