| + | ====== Encoder Tables in C Applications ====== | ||
| + | |||
| + | ===== makefile ===== | ||
| + | |||
| + | Add the "-DDONT_INCLUDE_MIOS_ENC_TABLE" define: | ||
| + | <code make> | ||
| + | # pass parameters to MIOS wrapper | ||
| + | MIOS_WRAPPER_DEFINES = -DSTACK_HEAD=0x37f -DSTACK_IRQ_HEAD=0x33f \ | ||
| + | -DDONT_INCLUDE_MIOS_ENC_TABLE | ||
| + | </code> | ||
| + | |||
| + | ===== main.c ===== | ||
| + | |||
| + | Add your table as such: | ||
| + | <code c> | ||
| + | ///////////////////////////////////////////////////////////////////////////// | ||
| + | // Application specific encoder table | ||
| + | // the default (dummy) table has been disabled via -DDONT_INCLUDE_MIOS_ENC_TABLE | ||
| + | ///////////////////////////////////////////////////////////////////////////// | ||
| + | MIOS_ENC_TABLE { | ||
| + | // sr pin mode | ||
| + | MIOS_ENC_ENTRY(1, 0, MIOS_ENC_MODE_DETENTED2), | ||
| + | MIOS_ENC_EOT | ||
| + | }; | ||
| + | </code> | ||
| + | |||
| + | ===== Reference ===== | ||
| + | |||
| + | Taken from mios wrapper | ||
| + | |||
| + | <code asm> | ||
| + | ;; ---[ configuration table for rotary encoders ]--- | ||
| + | #ifndef DONT_INCLUDE_MIOS_ENC_TABLE | ||
| + | ;; dummy table located in $MIOS_PATH/include/asm | ||
| + | ;; If the application should use ENC entries, | ||
| + | ;; just add "-DDONT_INCLUDE_MIOS_ENC_TABLE" to MIOS_WRAPPER_DEFINES | ||
| + | ;; and build the table within the C program with: | ||
| + | ;; | ||
| + | ;; MIOS_ENC_TABLE { | ||
| + | ;; // sr pin mode | ||
| + | ;; MIOS_ENC_ENTRY(1, 0, MIOS_ENC_MODE_DETENTED), // VPot #1 | ||
| + | ;; MIOS_ENC_ENTRY(1, 2, MIOS_ENC_MODE_DETENTED), // VPot #2 | ||
| + | ;; MIOS_ENC_ENTRY(1, 4, MIOS_ENC_MODE_DETENTED), // VPot #3 | ||
| + | ;; MIOS_ENC_EOT | ||
| + | ;; }; | ||
| + | ;; | ||
| + | ;; The MIOS_MT_* macros are defined in $MIOS_PATH/include/c/cmios.h | ||
| + | #include <mios_enc_table.inc> | ||
| + | #endif | ||
| + | </code> | ||
