Kyle_ISL Posted November 16, 2020 Share Posted November 16, 2020 Hello, I'm using Arty S7-50 boards for a lecture. By using simple edge detecting logic, I build a program which counts the number of button click. But board's button doesn't work stably such as counting twice by one click or counting increase while keep pushing the button. I applied several button denouncing logic, but can't solve the issue perfectly. So i guess buttons on the board convert its signal while while it is pressed. I have 30 boards of the same kind and they all have same problem. I'm wondering whether there is any other report on this issues. By your answer, I need to change my grading policy.

JColvin Posted December 9, 2020 Share Posted December 9, 2020 Hi @Kyle_ISL, I apologize for the delay. Have you gotten to try the Arty S7 GPIO demo, https://github.com/Digilent/Arty-S7-50-GPIO? It implements it's own button debouncing that, at least from my quick testing, doesn't double count or continually detect the press. Thanks, JColvin Link to comment Share on other sites More sharing options...
