AW: Re: Defektes MMIV Modul Bretterkennung falsch
 Zitat von Mychess
Hi,
The behavior of the diodes on the chessboard (if I understood correctly) is perhaps due to bad contacts.
Either the connector of the module or the wiring on the chessboard.
It is also possible that one of the drivers on the chessboard is defective.
Then, you have to check the power supply.
At the output of the HG5001, then the output of the voltage regulator.
If you can't test the RAM (with arduino or other), change the capacitors (especially electrochemical).
Cordially.
The Chessboard is still in good working condition and it works fine with other modules also a working MMIV module. The defective MMIV module makes the same Problem in other boards. It is like the figures are on the wrong position and the program dont get the right information about the position. Sometimes it is getting lovely signs in the display after reset. Thats why i think that the Ram is wrong. Take a look:
