Hello, I got a question regarding the Segger's Win32 code in USBBULK.c. In the function USBBULK_OpenEx(..) there is one line I don't understand: C Source Code (1 line) What happens here? thanks, Arne

Hello, I got a question regarding the IP code in 'IP_Config_LPC1788.c'.

The manual says the Softwaretimers use the C-Stack. What does this actually mean? Do they use the stack of the thread they just interrupted or the…

Hello, I got a question regarding the documentation for OS_Q_Create (manual 3.82f). For the parameter pData it says: "Pointer to a memory area used as data buffer for the queue." But the example is as this: C Source Code (5 lines) The '&' in front of '_acMemQBuffer' (line 5) puzzles me: that would be a pointer to a pointer to a memory area. Or am I wrong? Thanx, Arne
