Driver library for DKE Group 2.13" EPD
Supported model:
DKE DEPG0213RHS75AF1CP
Usage Example:
Config initialization:
depg0213_epd_t epd = {
.user_data = &hspi2,
.cb = {
.reset_cb = _epd_reset_cb,
.poll_busy_cb = _epd_poll_busy,
.write_cmd_cb = _epd_write_cmd_cb,
.write_data_cb = _epd_write_data_cb
}
};
depg0213_epd_init(&epd);
Callbacks:
depg0213_ret_t _epd_reset_cb(void *handle) {
// Implement your hard reset function here,
// RESET pin needs to be pulled low for at least 200us.
return DEPG0213_OK;
}
depg0213_ret_t _epd_poll_busy(void *handle) {
// Return DEPG0213_ERROR if timeout or error occurred.
// Implement your GPIO read function here.
return DEPG0213_OK;
}
depg0213_ret_t _epd_write_cmd_cb(void *handle, uint8_t *cmd, uint8_t len) {
// handle is the user pointer
// The first byte of the command need to set D/CX to low,
// while the rest of the command parameters requires D/CX to be high.
// Implement your SPI transmit function here.
return DEPG0213_OK;
}
depg0213_ret_t _epd_write_data_cb(void *handle, uint8_t *data, uint16_t len) {
// handle is the user pointer
// Set D/CX to high while transmitting data.
// Implement your SPI transmit function here.
return DEPG0213_OK;
}
Notes:
Pixels of this panel is organized in the similar way as SSD1306, but has 212 columns and 13 pages.
Therefore, when HORIZONTAL
or HORIZONTAL_INVERSE
modes are selected, the frame needs to be
transferred as pages. However, this controller chip has the function which can change the
self-increment direction of the internal pointer, so VERTICAL
modes are not affected anyway.
