Yes, there is a bug. CCS made a mistake when they changed the
driver to work with compiler versions starting with vs. 4.021:
| Quote: |
4.021 The & unary operator by default no longer returns a generic (int8 *)
|
The change that they made is incorrect.
Here is the correct way to do it. Substitute this code and it should
fix the problem:
| Code: | void setCursorAddress(int16 addr)
{
glcd_sendCMD(GLCD_CMD_SET_CSR_ADDR);
TGLCD_DATA
glcd_sendByte(*(int8*)&addr);
glcd_sendByte(*((int8*)&addr+1));
} |

This bug is in vs. 4.061, so I sent an email to CCS just now, to inform
them about it. Hopefully it will be fixed in the next version. |
