| #define | __CHARLCD_PLAT_INIT_HW 1 |
| Called from __charlcdOpen() to initialize the hardware. | |
| #define | __CHARLCD_PLAT_DEINIT_HW 2 |
| De-initialize the hardware. Called from __charlcdDeinit(). | |
| #define | __CHARLCD_PLAT_SET_POWER 3 |
| Turns on/off the Char LCD device. | |
| #define | __CHARLCD_PLAT_WRITE_4 4 |
| Writes a 4-bits data on the data bus. | |
| #define | __CHARLCD_PLAT_WRITE_8 5 |
| Writes a 8-bits data on the data bus. | |
| #define | __CHARLCD_PLAT_GET_STATUS 6 |
| Returns a byte indicating the status of each pin, being the MSB the pin D7. | |
The following values will be called from the Char LCD driver in order to give the platform control over the Char LCD device hardware. Users that may implement the Char LCD platform driver must create a plat_charlcd.h (and plat_charlcd.c) file to manage the following IO control codes with a __DEV_PLAT_IOCTL type function (dv_plat_ioctl member of the __DEVICE structure). See the __charlcdPlatIoCtl() example function.
The __DEV_PLAT_IOCTL function should return an appropriate error code like the following declared in Error codes.
code argument is unknown. The return code for success is usually __DEV_OK unless another error code is specified in the list below.
| #define __CHARLCD_PLAT_INIT_HW 1 |
Called from __charlcdOpen() to initialize the hardware.
The platform should initialize all the required hardware to start the Char LCD device.
| #define __CHARLCD_PLAT_DEINIT_HW 2 |
De-initialize the hardware. Called from __charlcdDeinit().
| #define __CHARLCD_PLAT_SET_POWER 3 |
| #define __CHARLCD_PLAT_WRITE_4 4 |
| #define __CHARLCD_PLAT_WRITE_8 5 |
| #define __CHARLCD_PLAT_GET_STATUS 6 |
