RX/TX LAN

[Storic]

on the dsPIC30F4013, on easy dsPIC2 board

In order to reach COM speed to 115200 for a Blue tooth serial interface, I needed to set the Oscillator source to Primary and the Primary Osc mode to FRC w/PLL 4x (fast RC 4x PLL).

to achieve the same with soft comms, HS2 was set to PLL x 16 and not FRC 4x PLL

Analogue ref on comms of 115200 via Bluetooth, all works OK

I tried to see how fast I could go with the comms, 115200 was the Max I could achieve (for now).

Code: Select all

#include <built_in.h>

unsigned adcRes;
unsigned rx1;
unsigned char uc1;

void main() {
      char *txt = "mikroe";
      int i=0;
      int error;

      ADPCFG = 0xFFFF;
      TRISB = 0x0;
     
  PORTB = 0x0000;
  TRISB = 0xFFFF;

 // Delay_Cyc(0,1023);   // added for softcoms
 // Soft_Uart_Init(&portf, 2, 3, 115200, 0); // softcoms at FRC PLL x 16
  Uart1_Init(115200);

  U1MODEbits.ALTIO = 1; // added to analog example
  Delay_ms(500);        // extended the delay

  while (1) {

      if (Uart1_Data_Ready())  {
     rx1 = Uart1_Read_Char();
     Uart1_Write_Char(rx1);
    }
 
  //**************************
 //      i = Soft_Uart_Read(&error);
 //     if (!error)
 //       Soft_Uart_Write(i);
 //     else
 //       Soft_Uart_Write('e'),Soft_Uart_Write(i);
 //***************************

 //   adcRes = Adc_Read(1);
 //   Soft_Uart_Write(adcRes);      //Uart1_Write_Char(adcRes);
 //   Delay_ms(5);
  }

}//~!
