Urgent!!...Problem with delay on china minipro with icsp on board

[solozerouno]

I have a problem that is a bug for my micro: I use Arduino mini pro micro and I noticed that if I use the delays with delay all the values ​​in milliseconds are worth more than 1 second, I think that the values ​​of the quartz are not 16 Mhz but less (type 8 or 4 Mhz) ..... Not being able to correct the value of the quartz which is fixed at 16Mhz everything is out of order ..... PS: I have a Chinese version of mini pro with icsp but both programming with TL866A that with Usb tiny everything is out of order but if I program a normal arduino with icsp with Usb tiny the Delay values ​​are correct ...... it is not possible to change the Mhz of the Arduino ?? There is a similar problem with attiny 85 but I have seen that if I vary from 8 Mhz the internal clock to 1Mhz the Delays are correct ..... I would like the possibility to change the clock on both pro and mini pro 328 5v and 3.3 ve maybe 128 .....

You could try altering the FCDX file for the board you are using..

This would usually be in C:\ProgramData\MatrixTSL\FlowcodeV9\FCD\ARD - open the file using notepad (or notepad++) - towards the beginning is a 'clock' section - change the "max_speed = ..." if needed and the "fixed=..." to "default=..." Where ... is the speed you want as a default value...

<clock max_speed="16000000"
master_divider="1"
fixed="16000000" />

to:

<clock max_speed="16000000"
master_divider="1"
default="16000000" />

It might throw some checksum errors on compile - but I think these are ignored at present...

Alternatively - use the AVR chip file (assuming you have the pack?)

hello.
There is also an 8MHz version to choose from:

What is the value of the crystal?
