How to develop a new project on the SPBTLE-1S module (based on BlueNRG-1 component)

Posted on 12/03/2018 by wp_2592768

SPBTLE-1S module is based on the BlueNRG-1 component.

For developing on the SPBTLE-1S module is necessary use the STSW-BLUENRG1-DK.
STSW-BLUENRG1-DK is evaluation SW package based on the BlueNRG-1 and BlueNRG-2 very low power Bluetooth low energy (BLE) single-mode systems-on-chip with 160 KB and 256 KB of Flash memory, respectively, 24 KB of RAM, 32-bit core ARM® Cortex®-M0 and ADC, GPIOs, I²C, RTC, SPI, Timers, UART, WDG and RTC peripherals.
The STSW-BLUENRG1-DK SW package contains a complete set of peripheral drivers (header and source files), which allow interface with the device peripherals (ADC, GPIOs,I²C, RTC, SPI, Timers, UART and WDG, RTC), and a complete set of related demonstration applications (header and source files).

How to manage two UART (USART2 and USART1) under Interrupt

Posted on 05/03/2018 by wp_2592768

There are different possibility to use the UART under Interrupt, for instance use PRINTF but this mode use a loot of code or, more efficiency is to use the Call Back.

In this example we use the Call Back modality.

This project was tested on NUCLEO-F030R8, was developed using the Cube-MX and the project is for ATOLLIC.
Thanks to Cube-MX is easy move this project on other STM32 mcu but also generate the same project for other IDE (KEIL, IAR, etc)

For use this project connect the NUCLEO-F030R8 to PC and use a terminal emulator, we suggest TeraTerm.
This because the USART2 is transferred to the PC like a USB virtual com port.

TIM14 PWM output, duty cycle regulated using a potentiometer

Posted on 02/03/2018 by wp_2592768

This example is an evolution of the: STM32 Basic Timer in Interrupt & PWM mode
In this example the duty cycle is regulated using a potentiometer.
See the diagram below.

All is developed using CUBE-MX and are generated for ATOLLIC.
Here there is the project for CUBE-MX, the project is generated for NUCLEO-F030R8.
