DATA LOGGING PROGRAM FOR TESTING ST7 APPLICATIONS VIA ICC

3 ST7 SOFTWARE

The PC application performs the initialization and starts execution of the ST7 application. At

this point, your ST7 application has to send the data bytes to the PC. The method you use de-

pends on the variant of the ICC monitor in the ST7 device because some ICC commands are

available only in the medium or extended variant and not in the basic variant. Please refer to

theST7 ICC Protocol Reference manual for the table listing ST7 devices with the ICC monitor

variant embedded in each type.

If the device chosen has a medium or advanced variant ICC monitor, you can just call the

ICC_Send_Byte routine at the address provided in the ICC Protocol Reference manual. If the

device has a basic ICC monitor, the send byte routine needs to be coded as part of your ap-

plication. The sample program provided with this application note includes a send byte routine

which you can use.

The software provided can be configured to support devices with any ICC monitor variant.

The ST7 software execution is given in Figure 3.
