Sen d and Repeat Send SERIN Window Text Input NMEA Mode When the SERIN ENABLE NMEA instruction is executed the IDE enters NMEA mode When a SERIN READ NMEA instruction is executed the IDE waits for the user to send the next NMEA sentence The sentences to send could be entered manually in the SERIN window but they are normally imported from a text file The sentences are not actually sent to the FPU until you select a sentence or group of sentences and press one of the send buttons The Send button sends the single sentence at the start of a selection The Send and Repeat button sends each of the selected sentences in sequence one at a time as each SERIN READ NMEA instruction is executed The user 1s not prompted for additional input until the selection has been completely sent The repeat action can be stopped by making another selection Only complete sentences are sent to the FPU If only part of a sentence is selected the complete sentence will be sent GPRMC 180303 A 5105 4550 N 11521 2573 W 0 0 328 9 100412 17 4 E A 34 GPRMB A rrrrrrrrrrr Vr A 1C GPGGA 180303 5105 4550 N 11521 2573 W 1 05 1 6 1322 0 M 17 4 M 46 GPGSA A 3 01 14 22 311 327 eee ae 1 6 1 6 35 GPGSV 2 1 07 01 46 289 40 11 41 256 42 14 63 061 41 20 15 292 33 76 SGPGSV 2 2 07 22 36 112 41 31 41 160 43 32 42 289 41 4A GPGLL 5105 4550 N 11521 2573 W 180303 A A 5C GPBOD 1I M 47 GPVIG 328 9 T 311 4 PGRME 276 4

27. 1 Reference Guide Auto Step and Conditional Breakpoints Reference Guide Auto Step and Conditional Breakpoints The Auto Step feature provides a means to automatically single step through FPU instructions This feature in conjunction with Auto Step Conditions can be used to implement conditional breakpoints Conditional breakpoints stop instruction execution when one of the specified conditions occur Breakpoints can be set for a variety of conditions including when a particular instruction is executed when a user defined functions is called when a specified number of instructions have been executed when a register value changes or matches a particular expression or when a string comparison matches a particular condition Multiple conditions can be specified and a breakpoint will occur when any of the conditions is met Conditional breakpoints are only active when the Auto Step operation is used They are not active when the Go or Step operation is used Instruction execution is much slower using Auto Step since an internal breakpoint occurs for each instruction and the debug trace and register data are checked for Auto Step Conditions Auto Step is activated by clicking the Auto Step button or selecting the Debug gt Auto Step menu item Auto Step Conditions are set by right clicking the Auto Step button or selecting the Debug gt Auto Step Conditions menu item The Auto Step Conditions can also be set to appear each time the Auto Step bu
