用語(terms)
| Term | Description |
|---|---|
| CS | Chip select |
| DIO | Digital Input Output |
| ECU | Electric Control Unit |
| EOL | End Of Line Often used in the term ‘EOL Programming’ or ‘EOL Configuration’ ICU Input Capture Unit |
| MAL | Old name of Microcontroller Abstraction Layer (replaced by MCAL because ‘MAL’ is a French term meaning ‘bad’) |
| MCAL | Microcontroller Abstraction Layer |
| MCU | Microcontroller Unit |
| MMU | Memory Management Unit |
| Master | A device controlling other devices (slaves, see below) |
| Slave | A device being completely controlled by a master device |
| NMI | Non maskable interrupt |
| OS | Operating System |
| PLL | Phase Locked Loop |
| PWM | Pulse Width Modulation |
| RX | Reception (in the context of bus communication) |
| SPAL | The name of this working group |
| SFR | Special Function Register |
| RTE | Runtime environment |
| WP | Work Package |
| ADC | Analogue Digital Converter |
| FFT | Fast Fourier Transformer |
| STD | Standard |
| REQ | Requirement |
| UNINIT | Uninitialized (= not initialized) |
| HW Unit | Represents a microcontroller input electronic device that includes all parts necessary to perform an “analogue to digital conversion”. |
| ADC channel | Represents a logical ADC entity bound to one port pin. Multiple ADC entities can be mapped to the same port pin. |
| ADC channel group | A group of ADC channels linked to the same ADC hardware unit (e.g. one Sample&Hold and one A/D converter). The conversion of the whole group is triggered by one trigger source. |
| ADC result buffer | The user of the ADC Driver has to provide a buffer for every group. This buffer can hold multiple samples of the same channel group if streaming access mode is selected. If single access mode is selected one sample of each group channel is held in the buffer. |
| Trigger Source | Source event that starts a single conversion or a continuous series of conversions. |
| Conversion Mode | One-Shot: The conversion of an ADC channel group is performed once after a trigger and the result is written to the assigned buffer. A trigger can be a software API call or a hardware event. Continuous: The conversions of an ADC channel group are performed continuously after a software API call (start). The conversions themselves are running automatically (hardware/interrupt controlled). The Continuous conversions can be stopped by a software API call (stop). |
| Sampling Time | Time during which the analogue value is sampled (e.g. loading the capacitor, …) |
| Conversion Time | Time during which the sampled analogue value is converted into digital representation. |
| Acquisition Time | Sample Time + Conversion Time |
