    Summary:

    1. printf(%f) always prints 0, even if the variable contains valid floating-point number.
      Change the On-Chip Ram size from decimal (such as 167.5KB / 167500 bytes) to binary (such as 167KiB / 171008 bytes).

    2. Character é is printed wrongly.
      Change the active code page of Windows's command prompt from 437 to 65001 (UTF-8)

Hi LiangYuG_Altera​ 

Thank you for your reply.

I think it's not a problem with rxbuffer[1] = 0x01 because the values in the debug window are good. So that seems that the memcopy were right.

As i put the first breakpoint at the first printf("SCD30\n"); the code before this brekpoint should be executed with the same time as usual and the values are good. The problem is when after this breakpoint i execute the code step by step the printf print the wrong values in juart-terminal. It seems also that there is print problem as the accentuated character "é for example" are not printed correctly. 

Regards

Eric
