Analog I/O Blocks

A

MotoHawk:Blocks:Analog Input

This MotoHawk® block outputs a uint16 value from 0 to 1023, representing 0 to 5V, sampled at the A/D converter. Select a unique resource name. This name can be the name of the sensor that is being read. If none is given, it will either inherit the pin name or the vardec name, depending on whether calibrateable IO is selected.

Choose the pin resource to read. For some modules, a lower reference voltage is available for each ADC channel.

"Output Creation Status" will add an optional uint16 output that provides the ControlCore error status. 0 means OK, and any other number is an error. Please type 'help motohawk_enum_error' for more information. This can be useful for disabling diagnostics or strategies based on different I/O calibrations.

MotoHawk:Blocks:Analog Input Reference

This MotoHawk® block outputs a uint16 value from 0 to 1023, representing 0 to 5V, sampled at the A/D converter. Choose the resource name (specified in the Analog Input block) to specify the analog input channel to reference. Either choose the resource to reference, or provide the name of a resource by name.

MotoHawk:Blocks:Analog Output

The MotoHawk® Analog Output block is used to control an internal resource on the GCM-5554-112-1001 (CCM1001) module, target '1751-6456 1751-6457' in the MotoHawk target definition block. It is not used for any external output pin. At present, it only supports the internal VISTA_DAC2 resource on this one module [MotoHawk 2009a and later; 21-Jan-2010].

Other options for generating an analog voltage output are discussed here:

This MotoHawk® block drives an analog output based on a uint16 value from 0 to 65535, representing negative rail voltage to positive rail voltage. Select a unique resource name. This name can be the name of the sensor that is being read. If none is given, it will inherit the pin name. Choose the pin resource to read.

P

MotoHawk:Blocks:Synchronized PWM Child

This MotoHawk® block, a synchronized PWM child, references a PWM Output parent block, and drives the output with a square wave with a specified phase offset relative to the parent. The child may have an independent duty cycle. Either choose the resource to reference, or provide the name of a resource by name, as defined by a PWM Output block. This is necessary when the parent pin is made calibratable.

The Duty Cycle input is an int16, ranging from -4096 to 4096, where 0 is 0%, 4096 is 100%. When negative, the polarity is reversed, which is only valid on PWM resources that are H-Bridge outputs, like ETC or H1. When "Output Current" is checked, the drive current in milliamps is provided. When "Output Fault Status" is checked, a value indicating fault status is provided. This value is one of: 0 - OK 1 - Fault 2 - Indeterminate

MotoHawk:Blocks:PWM Output

This MotoHawk® block's Duty Cycle input is an int16, ranging from -4096 to 4096, where 0 is 0%, 4096 is 100%. When negative, the polarity is reversed, which is only valid on PWM resources that are H-bridge outputs, like ETC or H1. The Frequency input is a uint32, ranging from 119 to 19988175. Each unit represents 0.01Hz. The actual range is limited.

When "Input Enable" is checked, the output may be dynamically controlled. When disabled, the output transistors are completely turned off, which will stop all current, but also disable any diagnostics. When "Output Current" is checked, the drive current in milliamps is provided. When "Output Fault Status" is checked, a value indicating fault status is provided. This value is one of: 0 - OK 1 - Fault 2 - Indeterminate When "Use as parent for synchronized PWM" is checked, a Synchronized PWM Child block may be used to reference this block.

MotoHawk:Blocks:Wide Range O2 Sensor

Choose the pin resource to read. Note, this block is only available on the ECU565-128 target.
