Hi all, Can any one tell me how do we declare data type for the variables having a fractional value float n=0.2; int16 A=540; float B=50e-06; float C=2.109375e-06;, i have assigned n,B,C as float. but DSP working in Fixed point.Should i mention the above as frac? how many bits whether it will take float as 16bit or 32 bit? or frac as 16bit or 32bit? if i give float16 it gives erro...

Hi all, Could you please tell me how do i perform computation with ADC outputs? I need to write commands in C. I know that ADC outputs can be accessbile through ADC result register. Incase if i do some computation with the results in ADC,should i get the value of ADCresult register in hexa, or binary or decimal? For example, i want the result of realtime voltage input, it would be in ADC res...

Hi ALL, I want WDCR and SCSR configuration details for watchdog reset. I have gone through the data sheet and configure them as per my understanding. In my case watchdog reset (I can monitor low reset signal at XRS pin using CRO) is happening. Sometime it is re-executing a code and sometimes it is not !!! And even if it is re-executing a code the WDFLAG bit in WDCR register is not getting set to ...

Hello, I've been toying with the C2000 toolbox for a little while now, but I'm hitting a wall on this one. What I'm trying to do is a PID controler whose parameters can be changed by an external source or using a RTDX channel. In fact this problem might arise for every block whose parameters can't be specified from the outside. Now I could create the controler with basic Simulink bloc...

Hi all, I'm trying to use the ADC on the ezDSP F2812 development board. I made a simple voltage divider in a breadboard using resistors and then buffered it with a voltage follower before sending it to the ADC pin for experimenting with the ADC. The breadboard is powered by a 3V3 voltage regulator. (It doesn't take it power from the board) When i looked at the output values of the AD...

Hi, I am new to this discussion group and hopefully someone can help to sort out my problem. I just got my 1st program flash into TMS320F2808 DSP on eZDSP board. In the application, I need to update some parameters/values from time to time. Because I included all these variable in the main program, I then need to flash the entire program everytime I updated the values. I am just wondering ...
