These things happen.
If you expect a more specific answer, provide some information. |

I'm using modbus, I'm using dspic30f6010a.
| Code: |
float m_decp[0];
(modbus_write_multiple_registers(MODBUS_ADDRESS,0x201,2,m_decl[0]));
|
For this I get error:
| Quote: | CORE-E0002: Trap due to misaligned data word access, occurred from instruction at 0x003a4c
|
PIC get reset.
Anyone can help for this? |

Looking at the prototype of modbus_write_multiple_registers, the problem reveals as a simple coding error
| Code: | | exception modbus_write_multiple_registers(int8 address, int16 start_address, int16 quantity, int16 *values); |
The values argument must be supplied by reference: &m_decl[0].
PCD performs no type checking for pointers in function calls, so no type cast is required. |
