Hey Pakesh,

Thanks for looking through the code, the signal monitor came up with the following:

This is the result, very strange because the sck doesnt function propperly. the CS goes to high too soon. the mosi and miso lines arent as expected as well.

Hello Patrick,

I have seen the code and although it doesn't respect certain OOP principles for clean duty, there are no apparent bugs in code. I would recommend also doing a signal monitor.

My kind dear,

Pakesh

Hello Pakesh, My code is in the zip file added to the original post. I can embed it in a comment as well if you prefer that?

Hello Patrick,

Could I please see the code in the question to check the current values?

My kind dear,

Thanks for the reply,

I have ordered this one: https://www.sparkfun.com/products/15033 It will arrive tomorrow. Did you perhaps have the time to look over the code? Maybe spot something I have missed.

Kind regards,

Patrick Torremans

Hello,

In situations like this my best approach is a logic analyzer trace, comparing working and failing. This will pretty quick show where the problem may be: e.g. missing or wrong signals, missing or wrong sequence of bytes, missing or wrong timing etc. Personally I use https://www.saleae.com/, but there are less costly solutions out there.

Best regards,
Kenneth
