This question already has an answer here:
I'm trying to set up the High Precision AD/DA Board from Waveform. The last step is to run
sudo ./dac8532_test, where it notes in the instructions that if command not found, to run
chmod +x. The command was not found, so I ran
chmod +x dac8532_test and tried
sudo ./dac8532_test again.
The command was again not found (
sudo: ./dac8532_test: command not found). I checked and the file dac8532_test is indeed in the directory I'm in (there are two other files with that name, but they have the extensions .c and .o if that matters).
What am I doing wrong? (Note: if there's any information I need to add, please let me know; I wasn't sure what was necessary.)
