2020-06-12 Hongjh First version
|
||
|
|
2020-07-23 Hongjh 1. Correct the macro define: DCU_CMP_TRIG_DATA01;
|
||
|
|
2. Refine the macro define for interrupt, flag and mode;
|
||
|
|
3. Modify API: from DCU_IntFuncCmd to DCU_GlobalIntCmd;
|
||
|
|
4. Delete API: DCU_SetCmpIntMode;
|
||
|
|
5. Modify DCU DATA read/write API.
|
||
|
|
2020-09-07 Hongjh Refine API: DCU_SetTriggerSrc
