 +===== Development Environment =====
 +
 +{{:​manual:​demos:​stm32f0_discovery.png?​200 |}}
 +
 +This demo is targeted towards the [[http://​www.st.com/​stm32f0discovery|STM32F0-Discovery]] board, with 64 kB internal Flash EEPROM and 8 kB internal RAM.
 +
 +To program the bootloader into the internal flash on the STM32F051 microcontroller,​ the on-board ST-Link Debugger Interface was used. However, this is not required if you have another means of programming the internal flash.
 +
 +To compile the demo programs you can use the [[http://​www.keil.com/​|Keil MDK]] development environment. ​
 +
 +The [[https://​www.olimex.com/​Products/​Components/​Cables/​USB-Serial-Cable/​USB-Serial-Cable-F/​|Olimex USB-Serial-Cable-F]] was used to create a connection between the STM32F051 USART2 serial peripheral and the PC's COM-port. The pin connections are as follows:
 +
 +  * Blue cable to GND (ground pin)
 +  * Green cable to PA2 (USART2 receive)
 +  * Red cable to PA3 (USART2 transmit)
 +
 +
 +===== Building and programming the Bootloader =====
 +
 +Before the bootloader can be used, it needs to be built and programmed into the STM32F051'​s internal flash memory. The steps in this section only need to be done once.
 +
 +When using Keil MDK, simply open the project from within uVision. The project file (stm32f051.uvprojx) is located at: \Target\Demo\ARMCM0_STM32F0_Discovery_STM32F051_Keil\**Boot**\ide\. Once opened, select Project->​Rebuild all target files from the menu to compile all the bootloader sources and link the together into the final executable.
 +
 +The bootloader program is now ready to be programmed into the internal flash memory of the STM32F051. Using your favorite programmer, flash the bootloader using one of the following files, depending on what file type your programmer supports:
 +
 +  * \Target\Demo\ARMCM0_STM32F0_Discovery_STM32F051_Keil\**Boot**\bin\**openblt_stm32f051.axf**
 +  * \Target\Demo\ARMCM0_STM32F0_Discovery_STM32F051_Keil\**Boot**\bin\**openblt_stm32f051.srec**
 +
 +
 +===== Building the Demo Program =====
 +
 +When using Keil MDK, simply open the project from within uVision. The project file (stm32f051.uvprojx) is located at: \Target\Demo\ARMCM0_STM32F0_Discovery_STM32F051_Keil\**Prog**\ide\. Once opened, select Project->​Rebuild all target files from the menu to compile all the demo program sources and link the together into the final executable.
 +
 +The output file is
 +
 +  * \Target\Demo\ARMCM0_STM32F0_Discovery_STM32F051_Keil\**Prog**\bin\**demoprog_stm32f051.srec**
 +
 +
 +===== Firmware update procedure =====
 +
 +To download the demo program \Target\Demo\ARMCM0_STM32F0_Discovery_STM32F051_Keil\**Prog**\bin\**demoprog_stm32f051.srec** using the bootloader, follow the instructions in the following links, depending on the communication interface you intend to use:
