| | | Version history |
| | | ---------------- |
| | | Version v1.0 released 24.6.2013 |
| | | Version v2.0_beta1 2015-01-18 |
| | | - parsing more compliant with SCPI-1999 |
| | | - support all parameter types defined in the spec - separate them and identifie them |
| | | - support for Arbitrary program data |
| | | - support for tagging command patterns (useful for common handler) |
| | | - support for extending any parameter type using SCPI_Parameter |
| | | - general support for number or text value (e.g. 1, 6, DEF, INF) not limited to one array of special numbers |
| | | - support for optional command headers (Richard.hmm) |
| | | |
| | | |
| | | Version v1.0 released 2013-06-24 |
| | | - support basic command pattern matching (no optional keywoards) |
| | | - support basic data types (no expressions, no nondecimal numbers, no arbitrary program data, ...) |
| | | - last version before refactoring of the parser and before extending parameter handling |
| | | |
| | | Future Version v2.0 released ???????? |
| | | - parsing more compliant with SCPI-1999 |
| | | - support all parameter types defined in the spec - separate them and identifie them |
| | | - support for optional command headers (Richard.hmm) |
| | | |
| | | |
| | | Command pattern definition |
| | |
| | | |
| | | The command callback can use predefined function to parse input parameters and to write output. |
| | | |
| | | Reading input parameter is done by functions `SCPI_ParamInt`, `SCPI_ParamDouble`, `SCPI_ParamString` adn `SCPI_ParamNumber`. |
| | | Reading input parameter is done by functions `SCPI_ParamInt`, `SCPI_ParamDouble`, `SCPI_ParamString`, `SCPI_ParamNumber`, `SCPI_ParamArbitraryBlock`, `SCPI_ParamCopyText`, `SCPI_ParamBool` and `SCPI_ParamChoice` |
| | | |
| | | Writing output is done by functions `SCPI_ResultInt`, `SCPI_ResultDouble`, `SCPI_ResultString`, `SCPI_ResultText`. You can write multiple output variables. They are automaticcaly separated by coma ",". |
| | | |
| | |
| | | .interface = &scpi_interface, |
| | | .registers = scpi_regs, |
| | | .units = scpi_units_def, |
| | | .special_numbers = scpi_special_numbers_def, |
| | | }; |
| | | ``` |
| | | |
| | |
| | | |
| | | If you discard some parameters, there is no way to recover them. |
| | | |
| | | Specifying `mandatory` parameter will introduce SCPI Error -109 "Missing parameter" |
| | | |
| | | These are the functions, you can use to read parameters |
| | | - `SCPI_Parameter` - read parameter to scpi_parameter_t. This structure contains pointer to buffer and type of the parameter (program mnemonic, hex number, ....) |
| | | - `SCPI_ParamInt` - read signed 32bit integer value (dec or hex with 0x prefix) |
| | | - `SCPI_ParamDouble` - read double value |
| | | - `SCPI_ParamNumber` - read double value with or without units or represented by special number (DEF, MIN, MAX, ...). This function is more universal then SCPI_ParamDouble. |
| | | - `SCPI_ParamText` - read text value - may be encapsuled in "" |
| | | - `SCPI_ParamString` - read unspecified parameter not encapsulated in "" |
| | | - `SCPI_ParamCopyText` - read text value - must be encapsuled in "" |
| | | - `SCPI_ParamBool` - read boolean value (0, 1, on, off) |
| | | - `SCPI_ParamChoice` - read value from predefined constants |
| | | |
| | | |
| | | These are the functions, you can use to write results |
| | | - `SCPI_ResultInt` - write integer value |
| | | - `SCPI_ResultDouble` - write double value |
| | | - `SCPI_ResultText` - write text value encapsulated in "" |
| | | - `SCPI_ResultString` - directly write string value |
| | | - `SCPI_ResultMnemonic` - directly write string value |
| | | - `SCPI_ResultArbitraryBlock` - result arbitrary data |
| | | - `SCPI_ResultIntBase` - write integer in special base |
| | | - `SCPI_ResultBool` - write boolean value |
| | | |
| | | You can use function `SCPI_NumberToStr` to convert number with units to textual representation and then use `SCPI_ResultString` to write this to the user. |
| | | You can use function `SCPI_NumberToStr` to convert number with units to textual representation and then use `SCPI_ResultMnemonic` to write this to the user. |
| | | |
| | | You can use `SCPI_Parameter` in conjuction with `SCPI_ParamIsNumber`, `SCPI_ParamToInt`, `SCPI_ParamToDouble`, `SCPI_ParamToChoice` in your own parameter type handlers. |
| | | |
| | | `SCPI_ParamNumber` is now more universal. It can handle number with units, it can handle special numbers like `DEF`, `INF`, ... These special numbers are now defined in parameter and not in context. It is possible to define more general usage with different special numbers for different commands, |
