Bus Pirate Support / Bus Pirate v4 LCD adapter v2a Free Pcb
This is the Bus Pirate v4 LCD adapter v2a from the pcb drawer
I had a little problem with the power supply, the vcc on the pcb is connected to 3.3v, I cut the trace and connected to the 5V
The lcd I tested is 2x16

Bus Pirate Support / Re: Bus Pirate v4 I2c Sniffing
I like it more and more, there is lots of stuff to do with the BP v4
the most I miss is storing the macros permanently, now I have to paste them over and over.
can`t wait for the next release to test the SUMP

Bus Pirate Support / Re: Bus Pirate v4 I2c Sniffing
Yes it works, I found that the stop bit is not sent and I suppose the write is not committed.
I tried the OLS but can`t make it to work, It doesn`t catch any data.
does BP v4 need some different initialization command from SUMP?

Bus Pirate Support / Bus Pirate v4 I2c Sniffing
I need to sniff traffic from a maple board to a 24lc1025 eeprom, it fails at writing, and I suspect a library problem, because with the BP I can read and write just fine.
I read very little about i2c sniffing, so far I see it sniffs under 100khz and in software mode.
is this true for v4 board also?
