Marcel,

Thanks for the reply, but it made no difference.

I am having problems getting serial data correct. I am using the Mega2561 at 11,059200 Mhz I send 31 bytes that end with $7E. I recive back only the first two bytes then the $7E byte. Below is my code. Ray. ******* Sent Data ******** 24 1A 00 80 A3 07 00 35 01 35 01 E2 01 38 00 99 01 66 02 0A 02 00 ...

Ken,

Yes the code does not work in the real world with the AT90CAN128. It does work if I use a MEGA2561 in place of the AT90CAN128.

Yes UART is ticked in the Library list.

Ray.

Changed from the AT90CAN128 to ATMEGA2561 and the same code works. That is a bug in my books. I have not used MikroPascal for about a year. My first attempt to use it again, I get a bug. Does anyone actually test all the features when adding support for micro's. I do not think so. I see the support ...

I cannot get the UART to work on the AT90CAN128. My hardware is okay, as code written in Bascom or AVRco works. This is my test code. I even tried adding UCSR1B.3:= 1; but it made no difference. Ray. program UARTtest; { Declarations section } begin { Main program } UART1_Init(9600); Delay_ms(100); w...

With the code below I get unwanted data sent. Why is this.

There is a bug that will not let you declare variables in the interrupt procedure. By declaring "Bytex" globally, it works, yet if you look at JPC's code you will see he declares three variables and claims his code works. I have used the MikroPascal compilers before and had to use other compilers du...

JPC, thank you for the reply. I have attempted to use your code, but get too many compile errors. It is too complex to modify your four uart interrupt code to suit the Mega88. If I am doing something wrong. Then what is wrong with this code. Ray. program UARTtestMega88; { Declarations section } var ...

This is from the data sheet. According to this I must read the data to clear interrupt flag. 18.7.3 Receive Compete Flag and Interrupt The USART Receiver has one flag that indicates the Receiver state. The Receive Complete (RXCn) Flag indicates if there are unread data present in the receive buffer....

If I send a byte, it outputs the 'Got it..' The next byte I send I get no reply. Ray. program UARTtestMega88; { Declarations section } var Dataready: Boolean; Comtask: Byte; {------------------------ UART Interrupt ------------------------} procedure UartInterrupt; org IVT_ADDR_USART__RX; // Uart In...

Thank you.

Ray.

Okay, my tests show it only reads the first byte. So how do you read all four bytes to get the real value.

Ray.

I want to read real values from the eeprom. This code compiles okay, but is the variable loaded with all four bytes, or just the first.

Marko, I have not looked at or posted on this forum for one year. I can see that nothing has changed. No support and no interest in fixing the problems with the software/compiler. To say that the update for the Pascal AVR compiler is been held up because of all the compilers are getting an update is...
