An image of a <space> in UART

115200 baud
8 bits
stop bit

I put the cursors on start of bit 0 and end of bit 7. The tail after the right cursor is the stop bit.

Hi Jan,

Nice! That will be extremely useful for printf debugging andall sorts of future projects, since UART is a key interface.

I tried with GCC, with the same makefile as before, but made these changes:

1. search-and-replace app_L1105 with EasyL1105_helloworld

2. search-and-replace main.c with helloworld.c

Then, I had to copy-paste the Debug/ti_msp_dl_config.c and Debug/ti_msp_dl_config.h files one folder up, where the helloworld.c is, since the makefile doesn't expect it anywhere else currently.

Then, it was built successfully. (The makefile is attached renamed as a .txt file).

Based on that, I think ideally the makefile needs to be modified to have a project name at the top so that it's easily modified, and, if I can figure out how, some way that the makefile will search for the ti_msp_dl_config.c/h files in the top level folder, and if it's not there, then search a Debug folder if it exists.

The Keil build would be more complicated : ( there's a uvprojx project it uses, which is XML, and would need a script to make that easy to modify to change app_L1105 to the target project name plus the main.c (and any other files) would be be changed in there too, so that's a bit of a pain, but not insurmountable, if there was a major desire to always be able to build with all three options! which probably isn't a realistic need anyway!
