Flash Loader
The STM32 Flash loader demonstrator (FLASHER-STM32) is a free software PC utility from STMicroelectronics, which runs on PC and communicates through the RS232 with the STM32 system memory bootloader.
To get an example of how to execute the device bootloader, refer to the STM32 microcontroller system memory boot mode Application note (AN2606).
To get information about the USART protocol used in the STM32 bootloader, refer to the USART protocol used in the STM32 bootloader Application note (AN3155).
Remember to put your STM32 in boot mode before to run Flash Loader.
For example for put in boot mode the STM32L031K6 is necessary connect to VCC (VDD) the boot pin that is pin 31.
STM has released a generic Serial to USB converter board named STEVAL-PCC018V1.
Below there is the typical wiring connections from the STEVAL-PCC018V1 to the UART of STM32.
Using the STEVAL-PCC018V1 is possible also power the user board because the STEVAL-PCC018V1 include also a regulator of 3,3V max 500 mA.
The max current is limited of the PC USB interface.
STM32 Standard Peripheral Libraries to STM32Cube Low-Layer APIs migration too
It is important that designers of STM32 microcontroller applications can easily upgrade their microcontroller type as well as their firmware solution.
Additionally, since the standard peripheral library is not delivered for the most recent STM32 series, the SPL2LL-Converter migration tool is essential to the harmonization of existing applications with the range of new embedded product features and the ecosystem evolution.
The STM32 standard peripheral library (SPL) to STM32Cube low-layer API migration tool is designed to help developers to easily migrate their source code based on STM32 SPL drivers to any other STM32 series supporting STM32Cube low-layer drivers.
It ensures full migration within a given STM32 series and partial migration across STM32 series.
The migration is possible only for STM32 peripherals covered by STM32Cube LL drivers.
ST Microelectronics is extending choice and freedom for budget-conscious designers by introducing its new 8-bit STM8S001 microcontroller (MCU) in the economical
SO-8 package.
New 8-bit Microcontroller from ST Microelectronics Delivers Uniquely Flexible Feature Set in Space/Cost-Saving 8-Pin Package
Unlike most rivals, the STM8S001 has I2C, UART, and SPI interfaces, giving unusually versatile connectivity options. With a generous 8KB Flash memory, 1KB RAM, 128-byte EEPROM, and 3-channel 10-bit ADC also on-chip, it delivers key features of ST’s most popular STM8S003 MCU in a space-saving, low-pin-count device.
Fully specified from -40°C to125°C
Benefits: performance, robustness and reduced system cost.
The STM8S001 in 8-pin SO-8 is in production now, priced from $0.20 for orders of 1000 pieces. A Discovery kit will be available in Q4 2017. See here.
The system cost is reduced thanks to a high system integration level with internal clock oscillators, watchdog, and brown-out reset.
Key Features
ST25R3911B-DISCO is a kit for ST25R3911B high performance HF reader / NFC initiator with 1.4 W output power, VHBR and AAT.
The ST25R3911B-DISCO is a ready-to-use kit featuring the ST25R3911B, an highly integrated HF reader / NFC initiator IC.
The ST25R3911B-DISCO can be operated as ISO18092 (NFCIP-1) active and passive initiator, ISO18092 (NFCIP-1) active target, ISO 14443A and B reader including very high bit rates (VHBR), long range ISO15693 and FeliCa™ reader.
Implementation of other standard and custom protocols like MIFARE™ Classic is possible using the AFE and implementing framing in the external microcontroller (stream and transparent modes).
The ST25R3911B-DISCO addresses a wide range of applications such as access control, ticketing, industrial, medical and consumer, where users need optimal RF performance and flexibility combined with low power consumption.
It contains a low power capacitive sensor that can be used for ultra-low power wakeup without switching on the reader field.
Traditional inductive wakeup with the choice of amplitude or phase measurement can be used as well.
The automatic antenna tuning (AAT) technology enables operation close to metallic parts and/or in changing environments.
The available software visually displays the impact of AAT, thus enabling an easy evaluation of the feature.
