Title: PIC3 MAXI WEB TCPIP DEMO
Post by: sdecorme on October 25, 2012, 01:46:14 pm
Hi I try to compile the "TCPIP PIC32 ETH Demo App-C32" demo but I've an error

MainDemo.c:193:2: error: 'UART1A' undeclared (first use in this function)

from this line
   putrsUART((ROM char*)"Initializing...");

It come from the Hardwareprofile.h line 2214
   #define UART_MODULE_USED       UART1A

I don't understand why the UART1 is not found , Any idea?

Great card I've already done a modified USB bootloader now I want ot make the ethernet bootloader.

Why You don't use the same ethernet chip as the microchip demoboard ?
Is it difficult to modify the microchip demo to use it whit your board ?

Thanks


If I comment all the putsuart function the next error is

from TCPPerfomanceTest.c line 221

      ultoa((DWORD)qw, vBytesPerSecond);

What is this ?

Hi there,

The demo from the stack will NOT work without modification with the generic stack you download from Microchip's stack. My advise is to check the provided modified code at (https://www.olimex.com/Products/PIC/Development/PIC32-MAXI-WEB/ (https://www.olimex.com/Products/PIC/Development/PIC32-MAXI-WEB/))

ultoa() - UNSIGNED LONG TO INTEGER - is a function that has been causing many problems among the PIC community because some compilers have it defined in which case you have to exclude the definition in your code and vice versa some compilers lack it defined and you have to define it yourself.

Best regards,

Thanks you for this tips.

Will you make an update to make your demo code compatible with the last microchip stack  5.42 ?
Thanks

I can't promise you this adjustment would happen soon. The reason are the requirements in FreeRTOS.
