MCU Templates are a kind of a common project framework or software framework needed for developers to have an easy start in development with MCUs. MCU Templates are historical started within Fujitsu (the times Fujitsu was a semiconductor company) by request of well-known customers. MCU Templates offering everything required to start development of embedded software … [Read more…]
The interrupt part of ARM Cortex M MCUs is described in CMSIS. The interrupt controller of ARM Cortex M MCUs is called NVIC. The NVIC is part of CMSIS and is decribed at the CMSIS website: https://www.keil.com/pack/doc/CMSIS/Core/html/group__NVIC__gr.html In general ARM Cortex M based MCUs having two types of IRQs: Core peripheral IRQs and MCU peripheral … [Read more…]
A Pulse Width Modelation (PWM) has a duty and a cycle. The duty can be something between 0% and 100% of the cycle time. For Ambiq Micro the CTIMER peripheral can be used to generate a PWM. GPIO setup First of all the GPIOs have to be set, see also Using GPIOs for more details. The … [Read more…]

The GPIOs of Apollo1 and Apollo2 series MCUs can be configured via a MUX for up to 8 different functionalities. Following schematic can be found in the datasheet in the chapter GPIO and Pad Configuration Module (Apollo1: chapter 6, Apollo2: chapter 7): The IO-cell itself can be configured in a complex way. The datasheet is … [Read more…]
A new feature of the new Apollo 2 MCU series is the so called SystemTimer. The SystemTimer or SysTimer is not the SysTick timer of the ARM Cortex M core, but adds new possibilities for real time behaviour scheduling in hardware with a little part of software. In addition it runs also in deepsleep modes! … [Read more…]

Gefunden auf Mikrocontroller.net: https://www.mikrocontroller.net/topic/427730 Mit dem dEEbugger setzt sich der Entwickler das Ziel, ein Äquivalent des Schweizer Taschenmessers für die Elektronikentwicklung zu bieten. Als Schlüsselanhänger stellt das Modul nützliche Funktionen für den schnellen und unkomplizierten Zugang zu einer Schaltung für Test- oder Analysezwecke bereit. Das Projekt entstand laut Entwickler aus der Not heraus, eine sichere … [Read more…]
Fujitsu Eletronics Europe had started to work on standalone examples for Ambiq Micro’s Apollo MCU. These can be found at: http://www.fujitsu.com/feeu A little bit difficult to find is the sub-page for the low-power MCUs of Ambiq Micro: http://www.fujitsu.com/uk/products/devices/semiconductor/ulp-mcus-rtcs/products/ulp-mcu/ At the page of Apollo 1 (http://www.fujitsu.com/uk/products/devices/semiconductor/ulp-mcus-rtcs/products/ulp-mcu/apollo/) the section “Sample Software” can be found. Currently FEEU offers … [Read more…]
