Z-turn Lite. Bare metal ARM Cortex-M Hello World on Linux. " It includes glibc support. EvalBot peripherals code. Over the past couple years I've switched over to instead using the STM32 series of microcontrollers since they are cheaper to program the "right" way (the dirt-cheap STLink v2 enables that). Provide details and share your research! STM32F103 SPI different pins does not work. Support for bare metal Cortex-M based boards was available only for a very limited range of Cortex-M3 cores, so of little use in GNU MCU Eclipse. You could certainly skip these headers and code directly with register addresses given in the datasheet - if you are feeling particularly masochistic. That chip has three UARTs on it, and I think they can go pretty fast; if you were to use one to communicate with the Raspberry Pi that would leave two available for other purposes. STM32F103 any good? - Page 1 STM32F103 for medium and STM32F407 when in need of serious processing power. [return] Some of you may be wondering if something stronger, like a memory synchronization instruction, is required here. This does not interrupt the connection to the serial monitor since there is a second STM32F103 that handles the serial monitor, programming flash, and debug. (STM32F103 VET6) This start-up code is meant to run on bare-metal, in other words, without any support from compiler or additional code.
