As in my first message, the SDA is high. Otherwise it would not pass the i2c_start. Checked with oscilloscope. After replacing cpu on both units no more problems.

The internal oscillator may be not a smart idea but if the drift was the problem it would happen no messages were received or sometimes a few.
This cpu stop after exactly 1 message. The I2C problem w ...

Yes i'm running 125khz CAN on internal oscillator. >20 different units. This can be problematic i know bit this cannot explain why after exactly 1 message never any will be received.

Of course you think impossible.

But what happens here. I have got a big network using CAN running for 8 years now and sometimes new modules are added most are unchanged for years.
A few months ago ...

Here my code by easy made because John Geek made a nice description. I did not implemented the checksum

Yes, but like that I have to double all +/-50 printf's with a lot of float printing. The code will increase a lot.

It would be handy if STREAM1 was a variable!

Sorry, did'nt read you measage. Th ...

My project uses UART1 with a command line interface. Now I want to use multiple pcb on a RS485 bus on UART2. The idea is to select 1 print on the RS485 bus and talk only to that one.

Is it possible ...

No problem! just uploaded it to the code Code Library

Hi,

Here my ported code for the MRF24J40MA. Load the same code at both boards and the characters 0..9 are send to the other side, bidirectional.
Please share your further development!

Hi,

This topic is old but I did the same. The code from MikroC is easy to translate. I made a working code, it can send and receive 3 bytes. The IRQ edge for the received signal needs to be H to L ...

My own way was the quickest:

static int16 month_days[2][13] = { { 0, 0, 31, 59, 90, 120, 151,
181, 212, 243, 273, 304, ...

Does some made a routine to calculate the local time from GMT. The GMT is from a GPS receiver.

Basic it is only calculate the minute of year, plus timezone and convert back to date and time.

According the datasheet of the 16F1825 it must be possible to set the internal clock to 32mhz 4x8Mhz PLL
However
setup_oscillator(OSC_8MHZ|OSC_INTRC|OSC_PLL_ON,0);
Does not work, pll_on or off no ...

There is no error since i added the extra E pins to the .H file. Now I want to be sure to have hardware uarts. So the first part of the code is with RX and TX connected to the hardware pins to use the ...

Thanks, I tried a putc. First with hardware uart and here the .lst:

.................... fputc('A',PORT1);
004FE: MOVLW 41
00500: MOVWF 19
00502: MOVLB 0
00504: BRA 03DA
