This application note is intended for STM8 firmware and system designers who need to implement an in-application programming (IAP) feature in the product they are developing with the STM8 microcontroller. The STM8 is an 8-bit microcontroller family with a Flash memory for storing the user program code or firmware. IAP makes it possible to update the firmware ‘in situ’, after the microcontroller has been embedded in the final product. The advantage is that the microcontroller board can stay inside its product enclosure. No mechanical intervention is needed to make the update. IAP is extremely useful for distributing new firmware versions. It makes it easy to add new product features and correct problems throughout the product life cycle. The user-bootloader firmware source code provided with this application note shows an example of how to implement IAP for the STM8 microcontroller. Use this code as a reference when integrating IAP in your STM8 application. It includes the following features: ● Bootloader activated by external pin (jumper on PCB) ● Flash block programing by executable RAM code management ● Read while write (RWW) feature ● High level C-language usage ● Reduced size of the code (optimized code) ● Support for multiple communication interfaces (SPI , I2C, and UART) ● UART code compatible with ST Flash loader demonstrator

The STMicroelectronics Medium- and High-density STM32F101xx and STM32F103xx Cortex™-M3 based microcontrollers come with 12-bit enhanced ADC sampling with a rate up to Msamples/s. In most applications, this resolution is sufficient, but in some cases where higher accuracy is required, the concept of oversampling and decimating the input signal can be implemented to save the use of an external ADC solution and to reduce the application consumption. This application note gives two methods to improve ADC resolution. These techniques are based on the same principle: oversampling the input signal with the maximum 1 MHz ADC capability and decimating the input signal to enhance its resolution. The method and the firmware given within this application note apply to both Medium- and High-density STM32F10xxx products. Some specific hints are given at the end of the application note to take advantage of the Medium- and High-density STM32F103xx performance line devices and of the High-density STM32F101xx access line devices. This application note is split into two main parts: the first one describes how oversampling increases the ADC-specified resolution while the second describes the guidelines to implement the different methods available and gives the firmware flowchart of their implementation on the STM32F101xx and STM32F103xx devices.
