Update the acc._tap after a shock detection

[marwa9]

I am working with Thymio robot . I am sending commands to Thymio and picking up the values of its sensors and acc._tap via a python code and saving these values into a database. I noticed that the acc._tap once it changes its value following a shock it keeps this last value even if there are no more shocks. I tried to modify my aesl file to reset this value after a tap event but it didn't work. Could you please help me resolving this problem?
Thank you very much for your time and your answer
