Hi, Just to answer some your questions briefly : 1) i'm not familiar with Atollic, but there is STLINK utility from ST, you can use it to program ST ARM MCUs. Can you run them at slower speeds if you don't need the performance? Does it have built in prescalers to select a slower speed? Why so many? Can you program with the 6, but not debug? Do you need the 10/20 for debugging? Q#6 - Do ARM's have a built in clock? Is it better than AVR clocks - can it be used for reliable UART? Is it a PLL that locks on to a slower speed clock? I noticed that ARM at Digikey have different clock speeds specified and I'm assuming that is their highest speed. I've seen 20 pin headers, 10 pin headers, and now this 6 pin header. I think it mentioned that that could be used to program the STM32 used for programming, but I could be wrong. Are these all necessary for a new nearly empty project that blinks a few leds? Q#4 - Where is the main source of documentation for peripheral libraries that are available? Are there different libraries avaiable? Q#5 - I noticed in one of the Nucleo boards that it talks about a SWD header that is 6x1 100 mil header. It created quite a few files such as startup_stm32f10x_md.s, stm32f10x_conf.h, stm32f1xx_it, system_stm32f10x.c. My question is does True Studio have a programming dialog like I am used to seeing in AVR studio? Where you can choose an ELF file and tell it to program the IC? Or erase it, etc? If not, is there another tool with this functionality for STLINK? Q#2 - Does the STM32 have fuses like I am familiar with on AVR's? Q#3 - I created a new project for the STMF103 board. I can then disconnect and it is programmed/will execute. Some more questions (not necessarily related to freeRTOS, but STM32 and Atollic TrueStudio in general): Q#1 - To program the Nucleo board I have selected "debug" and it then programs it and starts it. I'll have to get my hands on the definitive guide.
