Hi, I intend to use SCI1 in raw data format on a 56F805 using Codeworrier and the SDK. The very first byte of a 6 word packet I send to the DSP is always missing. When I use 8 bit character transfer it works fine (apart from the wasted memory). Anyone an idea how to get hold of the first byte? Do I have to send a dummy byte first for each packet i send? Many thanks. Manfred

How are you sure the lost first byte is on the DSP end? I've had problems with nulls getting dropped by the Windows terminal and hosing me up. Is your first byte 0x00? --david --- In , "Manfred Plagmann" <m.plagmann@i...> wrote: > Hi, > I intend to use SCI1 in raw data format on a 56F805 using Codeworrier > and the SDK.
