Hello, I have bought a Max32 and a Basic I/O Shield. I have downloaded EEPROM library and I have tested the example sketch (see attached file), but it doesn't work.

I have modified the sketch with two message on serial monitor (at the beginning of Setup area):

Serial.begin(9600); Serial.println("Step 1"); OShieldEEPROM.writeString(0,"ABCDEFGHIJKLMNOPQRSTUVWXYZ"); Serial.println("Step 2");

"Step 1" is displayed on serial monitor but "Step 2" is never displayed. I have tried to connect pin 20 and 21 on Max32 to A4 and A5 on BasicIO, I have tried also to connect pin 20 and 21 on Max 32 to SDA and SCL on the BasicIO J11 connector. I need some help, please Best regards

What version of MPIDE are you using? Please dowload the 0316 version and try the sketch one more time. The new version of MPIDE 0816 has a different compiler and does not play well with the IO_EEPROM Library.

Best regards,

Hi, Thank you for your answer. I have only the MpIde 20140821 version. Do you have the URL to download the 0316 version ? Best regards

Hi JessN,

Thank you for your help. I have found the right version (20140316) and the shields EEPROM and the Temp sensor are running correctly. Thank you one more time. Have a good day Papyroot
