Obviously P18F87K22 although it objects if I try to change the Mmc_Chip_Select from RE0 to RA0.
I would like to use a smaller PIC with large ROM and RAM memory like the P18F23K22.

Hello.
Since a short time I use CRTOS with mikroPascal PRO for PIC. I use PIC18 controllers.
What I miss in CRTOS is messaging. One task shall i.e. do the serial I/O. Other tasks tell this one task what to send (a string), so I can prevent any collisions. Also, this one task can receive and dispatch /forward incoming data to particular other tasks.
Such things work best with message pipes (N-to-1 and 1-to-N pipes).
Is something like this already available?

I am using PIC18F45k22, RTD Click and DAC Click. I managed to execute the example code successfully on EasyPIC7 board. Now my aim is to merge the two example code and pass the RTD value (0-250) to DAC click (0-4095), so that I can have RTD reading in terms of a Voltage output. PIC18F45k22 act as the master to relay this operation.
To begin with, I merged ADC click and DAC click and it worked well.
however, when when I merge RTD and DAC, RTD does not seem to give me correct temperature reading. Code below is the RTD Click example with DAC click header includes and also microbus2 definition under systemInit(). This prints wrong temperature readings (way off the expected values). once I remove the microbus2 definition, it works well.
Could you please help on this
#include "Click_RTD_types.h"
#include "Click_RTD_config.h"
#include "Click_DAC_types.h"
#include "Click_DAC_config.h"
void systemInit()
{
mikrobus_gpioInit( _MIKROBUS1, _MIKROBUS_CS_PIN, _GPIO_OUTPUT );
mikrobus_spiInit( _MIKROBUS1, &_RTD_SPI_CFG[0] );
mikrobus_gpioInit( _MIKROBUS2, _MIKROBUS_CS_PIN, _GPIO_OUTPUT );
mikrobus_spiInit( _MIKROBUS2, &_DAC_SPI_CFG[0] );
mikrobus_logInit( _LOG_USBUART, 9600 );
Delay_ms( 100 );
}
void applicationInit()
{
rtd_spiDriverInit( (T_RTD_P)&_MIKROBUS1_GPIO, (T_RTD_P)&_MIKROBUS1_SPI );
rtd_writeRegister(_RTD_CONFIGURATION, 0xD0);
}
void applicationTask()
{
uint16_t readValue;
float convertedValue;
char testTxt [20];
char testTxt1 [20];
readValue = rtd_readTemperature();
convertedValue = rtd_convertTemperature(readValue, _RTD_REF_RESISTANCE_470);
floatToStr(readValue, testTxt1);
floatToStr(convertedValue, testTxt);
mikrobus_logWrite("Current temperature: ", _LOG_TEXT );
mikrobus_logWrite(testTxt, _LOG_LINE );
mikrobus_logWrite("Voltage: ", _LOG_TEXT );
mikrobus_logWrite(testTxt1, _LOG_LINE );
delay_ms(800);
}
void main()
{
systemInit();
applicationInit();
while (1)
{
applicationTask();
}
}

I'm using Mikroc 7.5, In predefined FAT32 library there's a function,
FAT32_FindFirst(__DIR *pDE);
I don't know how to use this function, I need example code for this ???
