Hoping someone can point me in the right direction - and apologies for not being much of an EE !
Currently trying to get access to my car head unit - long story short, I can see data fine using a logic analyser and pulseview but get absolute garbage when using either ft232rl, cp2102 or even a max3232.
Pulseview uart decoder set to 9600 8n1 no parity, not inverted and lsb first - about as standard as it comes.
Looking closely in pulseview I seem to be getting erroneous "spikes", seemingly not enough to generate any frame errors or misinterpreted breaks - but still, doesn't look right.
Or am I going completely the wrong route here?
Any ideas much appreciated!
