pic16f1936 - hhhluck - 2014-06-04

I have problem can't connect PC
it just time out
I have to define PIC with 485
DE(RC5)(1 for Send) and RE(RA1)(1 for Receive).

but the "setting.inc" have no RE can define ,
i think "USE_TXENABLE" just set DE.

and in "uart.inc" i can't read asm code ,so i have no idea to modify the code.
the download have C code firmware? the "ds30 Loader
Firmware manual" say have the c code,but i didn't find.

Please teach me to modify asm code or show the C code example.
Thanks

RE: pic16f1936 - Mikael Gustavsson - 2014-06-04

That should not be a problem because rx is disabled by the CREN bit in the RCSTA register while transmitting. Please zip and post your boot loader project.

RE: pic16f1936 - hhhluck - 2014-06-05

my project is for mplabx , file is bootloader


and my app use 485 code with C(piece code)
Code:
#define RE LATA1   
#define DE LATC5
for Receive
Code:
void ur_init(void) {
    INTCON = 0b00000000; //GIE and PEIE disable;TO and INT enable;IntFlag cleared
    SPBRG = 25; // 19200  8M  HIGH 25
    BRGH = 1;
    RCSTA = 0x90;
    // RCSTA: SPEN RX9 SREN CREN ADDEN FERR OERR RX9D 
    //           1   0    0    1    0     0    0    0  
    TXSTA = 0x06;
    // TXSTA : CSRC TX9 TXEN SYNC -- BRGH TRMT TX9D 
    //          0    0   0     0       1    1    0   
    rclenth = 0;
    txlenth = 0;
    TRISC7 = 1;
    RE = 1;
    DE = 0;
    CREN = 1;
    RCIE = 1;
    INTCON = 0b11000000;
}

Send
Code:
DE = 1;
    RE = 0;
    TXEN = 1;
    TXIE = 1;


RE: pic16f1936 - Mikael Gustavsson - 2014-06-07

Please try this one, I have added support for an rx enable pin.

Which RS-485 tranceiver are you using?

RE: pic16f1936 - hhhluck - 2014-06-10

PIC16F1936 -> ADM485EARZ -> USB-COM485-PLUS2-FTDI -> PC
i want to know this LINE can write five pic by broadcast(connect with 485) in time?
pic is my app mem.

i want to know "ds30LoaderNativeConsoleLinuxArm" is not in free mode?
this file i didn't find.

RE: pic16f1936 - Mikael Gustavsson - 2014-06-23

Hi,
I am sorry for the late reply.

The Linux ARM client is not part of ds30 Loader free edition, it is purchased from MG Digital Solutions. See www.ds30loader.com for more information.
Simultaneous programming of multiple units is not supported in ds30 Loader free edition.

The warning about the config words being to large is a bug with the assembler. You can safely disregard it.

RE: pic16f1936 - Mikael Gustavsson - 2014-06-23

Does it work better with baud rate set to 9600 or something else?
