Hello everyone,
I am currently using the TMS320C5515 eZdsp USB Stick Development Tool, with the example projects coming with the corresponding CSL. In particular the one for the GPT: CSL_GPT_Example_Out.
I have modified the timer prescale and period as follows:
hwConfig.preScaleDiv = GPT_PRE_SC_DIV_0;
hwConfig.prdLow = (sysClk)/850;
I expect then a GPT frequency of 425 KHz.
I use the GPIO14 corresponding to the blue led of the eZdsp in order to verify the GPT frequency. For this I toggle the value of the led in the GPT ISR. (The measured frequency should then be divided by 2)
My measured frequency does not corresponds to the programmed frequency! I have noticed that the frequency is correct when programming the GPT to a maximum of 400 KHz.
Any help on this problem that anyone could provide will be very much appreciated!
Veronica
