ECall to read input from stdin #286

Closed tn4799 closed 1 year ago

tn4799 commented 1 year ago

Hello. I've noticed that there are no ecalls to read input from stdin / the console. Did i miss something or is there no implementation for that? And if there is no ecall for reading input may you consider implementing ecalls for reading strings and numbers from stdin?

Have a nice day.

This should definitely be there - try the consoleReading.s example which uses the '63' ecall (see Help->System calls inside Ripes).

For me the demo hangs waiting for the user to enter the characters. I tried pressing enter and many other keys but nothing seems to work. What am I doing wrong?

So do i. It always show the message " Waiting for user input..." Opening the console of Web Browser, I found that this issue concerns permissions such as clipboard, cookie. Screenshoot from Chrome Clipboard permission

Approving the clipboard permission. it still raises anothor warning. However, i cannot fix it. :(
