Rapid Development - Virtualised SPI
A feature of the App Developer Slave interface is to use the component for rapid development.
The App Developer Slave hardware can be used to take communications from the Flowcode simulation and transfer them to a real world device allowing for easy code generation and test without having to download to a target microcontroller device.
The CS pin and SPI Prescaler are set via the properties of the Injector component.
The SPI Master component is linked to the Injector component via the Injector property.

Properties |
|
Connection Type |
|
Auto Detect Port |
| Allows the component to auto detect the interface board COM port. Requires the latest Flowcode serial comms DLL to function correctly. | |
|
|
Network Interface |
| Some computers may have several network interfaces such as ethernet ports and wifi access. Select the correct network interface for the network you wish to connect to. Use the IP address to confirm you are connected to the right network. | |
|
Local IP Address |
| IP Address of the selected network interface. | |
|
|
Board IP |
| IP Address of the device we want to control | |
|
|
Auto Detect IP |
| Allows a device connected to the same subnet as the local IP address to be automatically detected. Scan may take a few minutes. Console reports progress. | |
|
|
Scan Results |
| Lists the IP addresses found during the last scan, Overwrites the selected WIFI IP property when changed. | |
|
Scan Start |
| Address to set the scan start point. For example 10 might generate 192.168.1.10 depending on your IP setting. Scan then proceeds from there so for example 11, 12, 13, ..., 254, 255. Default 0 | |
|
|
End Scan |
| Decides how the scan is terminated | |

Console Log |
| Create an automatic console log of the commands sent to the device | |
|
|
Log Mode |
| Controls how the console data is formatted. Fixed statistics gives an easy to read overview of the IO, Analog and PWM functionality Command Log gives a more in depth analysis of the outgoing commands and incoming returns ASCII mode allows serial data to be shown in raw text form, other commands are shown as in the Command Log mode | |
