Gw Instek GDS2204E (200MHz 4 channel DSO) review
CC555:
Yes, that was my initial setting. The result is the same.
2N3055:
I agree with nctnico, set polarity back..
Values in the first photos with original polarity on GW instek are shifted to left ....
hex 1 -> hex 2
hex 2 -> hex 4
hex 19 -> hex 32
you must check if both are exactly 1 start bit, 8 data , no parity and 1 stop bit... 10 bits total.
It seems GW Instek is stuffing additional bit in the beginning (LSB)
CC555:
Settings are ok: 57600 8 N, I have not found the stop bit option, there is an end of packet option (00 NULL by default).
nctnico:
I did some testing and I've found the problem. At 2Ms/s your samplerate is too low. I was able to reproduce the problem but it went away at samplerates of 10Ms/s or more.
2N3055:
Good info Nctnico.. :-+
