Question: The pin 3 of the RS485 module on the demo board is attached to RF12_PIN40_SCK1. But from your text file it seems you are moving 0/1 PORTFbits13 and not PORTFbits.RF12. Is that correct? Could you try moving PORTFbits.RF12? Answer: We tried to move 0/1 PORTFbits.RF12 as well (we forgot to me...

We performed some tests with the RS485 module using the multibus and daughter board. The results are in the attached file. The nodule works fine using the multibus board. With the daughter board, the pin 3 (TXEN pin) of the module is never at high level and doesn\'t work. The JMP 4,5,6 on the daught...

could you send me the schematics of the RS485 module and multibus module?

ciao

We tried the attached code, but we wasn\'t able to receive data.
The instrument replies correctly to the command, but no data on the UART2_Receive...
Thanks

We don\'t understand which pin we have to set using JP2 and JP3 in 1-2 position. In UART2.h we found: /* Set IO pins */ TRISFbits.TRISF4 = 1; // RX Pin TRISFbits.TRISF5 = 0; // TX Pin We tried to change the value but without success Could you explain better how the MCU controls the RX/TX mode?

We are trying to use RS485 to communicate with an instrument. Our hardware is dsPIC Flex Full board (Flex003) and Flex Demo Daughter board (Flex109) with RS485 Module (Flex104) mounted on it. We are able to correctly send data to the instrument, but we are not able to receive the answer from it. We ...

We have modified the code according to your suggestions and all works fine! Thank you for your help.

We have tried to run the rs232 test using EE 1.5.0 alpha. Nothing changed: the results are the same as using EE 1.4.3 (send OK, receive KO..).
Attached is the file code.c used.
Could someone help us?
bye

About the download of the Erika Enterprise 1.5.0 alpha: we tried today and the download worked fine. So we plan to try it next week.

The serial example works using UART2 and SEND function only. Furthermore, as in the rs232 original example, we used loops (SetRelAlarm(AlarmSend, 500, 500) and SetRelAlarm(AlarmReceive, 500, 500). We have verified that the instrument receive correctly the command and reply correctly, but we don\'t r...

Abbiamo reinstallato tutto l\'ambiente di sviluppo nella seguente sequenza:
1) Mplab IDE 8.10
2) C30 compiler versione 3.10b student (stavamo usando la v.3.11b)
3) EE 1.4.3
Ora funziona

Grazie,

Ciao
