After your quick support according to the latest cores I hop that somebody can help me with this issue: My ZX-Uno XL has worked fine with the latest core EXP26 installed in 2018. After not using the device for about a year or more the ZX Spectrum keyboard doesn't work correctly.
Problem: The mapping of the Symbol-Shift key is gone. Neither Symbol-Shift + L prints "=", nor changes Symbol-Shift + Caps-Shift the cursor to the extended mode (flashing "E") in 48k mode.
The control keys (Symbol-Shift + Caps-Shift + Y for NMI, Symbol-Shift + Caps-Shift + N, Symbol-Shift + Caps-Shift + B, and so on) were working properly.
- Several Spectrum keyboards have been tested.
- All combinations of the BIOS settings <Main - Keyboard - Issue x> and <Advanced - Keyboard Layout - Default|Spanish|English|Spectrum> have been tested
As the ZX-Uno XL works fine using a PS/2 keyboard I think it's an issue with the key mapping of the 328P chip.
Last I tried was updating the Arduino on the ZX-Uno board with the latest version of https://github.com/spark2k06/zxunops2
Result: In combination with EXP27 core and BIOS Setting <Keyboard Layout - Spectrum> Symbol-Shift + <key> works (Symbol-Shift + A writes " STOP ") but I still can't reach the extended mode in 48k BASIC or print a "(c)" symbol or reach the " INT " command...
Any suggestions?
Thanks for the info.
