working device is difference , i need to work on dsPIC33FJ16GS504 when config UART interrupt as 0x10 U1STAbits.URXISEL0 = 0; U1STAbits.URXISEL1 = 1; // Interrupt after one RX character is received . then, each time when changing using new address number, slave_RS485 need 2 times trigger to get a ret...

any RS485_Slave_Example for dsPIC33FJ16GS504 ?

thanks for clarify

any reply from mikroElektronika team member ?
are this typing error or
have to type-in 2 line same code ?

refer to RS-485 Library, example, are this needed 2 line same code ? it does not make sense to me. RS485Slave_Init(160); // Intialize MCU as slave, address 160 ... ... URXISEL1_U2STA_bit = 0; URXISEL1_U2STA_bit = 0; ... or replace to this code U2STAbits.UTXISEL0 = 0; // Interrupt after one TX charac...

thank you for respond.
if external/extra chip need , any idea for this ?
i'm thinking of "signal pattern generator" 1 channel will do,
any info ?

RS232 interrupt run very slow, some time can't respond to PC. at first i thought might be 232 coding error. add-in a CN-interrupt () to see LED light-up more visualize the issue //void __attribute__ ((interrupt, no_auto_psv)) _CNInterrupt(void) //mplabx INT. code void CNInterrupt() iv IVT_ADDR_CNInt...

when timer at high interrupting rate, CPU speed slow down. any idea to get back CPU speed ? add another chip? any idea? now my RS232 interrupt can't run. // MCU: dsPIC33FJ16GS504 // Oscillator: 80.000MHz // SW: mikroC PRO for dsPIC30/33 and PIC24 //Timer2/3 //Prescaler 1:1; PR3 Preload = 0; PR2 Prel...

have remove slave delay10ms and still works. faster now. wandering if it can go for 32 slave? at each 300m distance?

LED0 blanking seem looking sync. (to my stopwatch) by visual brief verification :wink: , 32768/tick at Timer1 prescaler to 1:1 TMR1H.B7 = 1; // 65536-32768=32768=0x8000, 1 tick/sec //TMR1L = 0x00; than using 4096/ticks, at Timer1 prescaler to 1:8; 4096/ticks run faster by brief visual inspection. co...

oops! i miss type some code if (tick_flg) { tick_flg=0; TMR1IE_bit =0; // only Mask the TMR1 interrupt while messing with TICK TMR1H = 0xF0; // 65536-4096=61440=0xF000, 1 tick/sec //TMR1L = 0x00; tick=tick%10; // Retain the left-over ticks tick=(tick/y)%10; sec += tick; // Add the accumulated second...

look better :) :) what will happen on RCIF_bit & TMR1IF_bit flg at the same time ? // Interrupt routine void interrupt() { if (RCIF_bit) { RS485Master_Receive(dat); } if (TMR1IF_bit) { tick_flg=1; tick++; TMR1IF_bit =0; } //timer ticks }//interrupt end ...... void main (){ ...... ... ..... while(1) ...

Modules: Character LCD 2x16 SW: mikroC PRO for PIC 4.60 although i using Xtal, but doubt ? on the accuracy on 1 second tick ? how accurate it will be ? any input ? void main() { O...
