Specification of ADC Driver

Calculation of Baud rate: Valid only if the group is configured to be triggered by a hardware event. Alternative function Sw Reception 2. Adcdrievr hardware priority mechanism is supported and selected: The ADC driver stores all group conversion results to result buffer addressed with the result buffer pointer.

Lowest priority is 0. Type of clock input for the conversion unit to select different clock sources, if provided by hardware.

The actual resolution has to be less or equal than the maximum resolution.

Please considered the image given below. A dedicated data structure for the returned values of a conversion is now clearly defined.

This module does not provide a schedulable main function. Starts the conversion of all channels of the requested ADC Channel group. This is a general software integration requirement.

Specification of ADC Driver

LIN clock is divided by this Prescalar. If development error detection for the ADC module is enabled and the priority mechanism is disabled and the queuing is disabled: Replacement mechanism, which is used on ADC group level, if a group conversion is interrupted by a group which has a higher priority. If the adcddiver shall be interpreted as signed value it shall apply to Clanguage rules.

The ADC module supports the following start conditions or trigger sources: The application result buffer layout is shown in Figure 2. Multiple — the configuration parameter shall be of configuration class Post Build and is selected out of a set of multiple adxdriver by passing a dedicated pointer to the init function of the module. Software triggered one-shot conversion without notification 77 of Document ID The ADC module shall only store one conversion request per channel group, not multiple requests, which may occur if a high priority long-term conversion blocks the hardware.

Autpsar finishing the scan the notification if enabled is called. UART errors are handled and. The configuration parameter shall never be of configuration class Pre-compile time. The following rules shall apply to the driver implementation: Hardware triggered one-shot conversion where the converted group consists of exactly one channel. Sign up using Facebook. The organization of this It makes above layers independent of ECU hardware layout.

The reentrancy of the API functions applies only adcdrover the caller takes care that there is no simultaneous usage of the same group. The conversion of an ADC channel group is performed once after a trigger and the results are written to the assigned result buffer. To correct this error, reconfiguring LIN module to proper bit sampling point is required.

For description of boundary conditions for the criteria of the development error swe refer to chapter 8. One-shot conversion means that 21 of Document ID The adcvriver development time and software portability are required for standard core solutions. Reception function reads the receive buffer which has received byte. Seems like in my toolchain the order is defined by the sequence how you add the AdcChannels to the AdcGroup: Changes between any other modes are not swws.

The converions round of the interrupted group is completed after the higher priority group conversion is finished. Continuous conversion where the converted group consists of exactly one channel. In single access mode this parameter assumes value 1, since only one sample per channel is processed. The symbolic names of ADC channels and ADC channel groups for use by the upper layer shall be defined by the configurator.

Auto scan, continuous conversion. The material contained in this specification is protected by copyright and other types of Intellectual Property Rights. Function called prior to initialization. Just one conversion result of each channel within a group. They must be added in the Vendor Specific Module Definition.

The number of hardware triggered requests which can be stored simultaneously, is dependant from the ADC hardware module. The diagrams show all possible configuration options for ADC groups. In case of Variant PB: It contains internal device drivers with direct access to micro- controller and peripherals.

Furthermore the table also depicts a possible realization and the mapping of these functionalities to the capabilities of a commercial microcontroller C16x.

At this point it shall be pointed out that the code-file structure shall include the following file named: This parameter is the symbolic name to be used on the API. Then a new scan is started automatically.
