Why uVision Serial Window doesn't display numbers above 0x7F? Instead of doing it, uVision hangs up until reset. How can I resolve this problem? My uVision version is V4.22.0.0.
You can configure the µVision as explained at: http://www.keil.com/support/man/docs/uv4/uv4_dg_configsettings.htm (Courier of course still is selectable at the "Font"-Tab)
For test purpose just rename your projects uvgui-file to get the editors default layout loaded at restarting that project.
