Other Parts Discussed in Thread: CONTROLSUITE
Hi,
Related to my previous question about transmitting the result of the adc to a hyperterminal via SCI which I managed to transmit the result correctly. Now I want to save the AdcResult to text file to be used later for further processing. what I added so far to my amended "adc_soc_epwm_cpu01.c" example are:
1- I defined a file Globally as (FILE *myFile).
2- In the Adca1_isr below I created a condition to open and close the file.
3- I tried to save a simple counter to the file using the fprintf function which resulted in that the alocated RAM for .text is not enough. SO I tried to change the .text ram alocation as following:
//.text : >>RAMM0 | RAMD0| RAMLS0, PAGE = 0 // I chaged it to this previously so that sprintf to work and it worked correctly.
.text : >>RAMGS12 | RAMGS13| RAMGS14| RAMGS15, PAGE = 1 // I chaged the above line to this line so that the fprintf works.
but when I did this change, the error which showed below is no more exist. HOWEVER, when I debug and run the project, the adcaResults buffer didn't receive and conversion results.
"C:/ti/controlSUITE/device_support/F2837xD/v210/F2837xD_common/cmd/2837xD_RAM_lnk_cpu1.cmd", line 54: error #10099-D: program will not fit into available memory. placement with
