Tool/software: TI-RTOS
Dear All,
I am trying to develop an Ethernet based data acquisition system using TM4C129ENCPDT using external ADC with sampling frequency approximately 32ksps. I have selected TI-RTOS and its NDK, and implemented UDP communication. I have interfaced the ADC separately also. Issue is that, when integrating this two, Since the ADC needs the tick time in microseconds, I have to choose the tick time in RTOS as 1us, then the Ethernet communication is not perfect. It is inference with the high speed ADC interfacing. ADC-SPI reading is based on the hardware interrupt generated by the ADC, and the sampling rate determined by the master clock generating from the timer module. If the timer speed is less Ethernet will work properly, But ADC sampling rate not match. If timer rate increased to ADC sampling rate, then Ethernet communication broken.
Any Solution?
What is the minimum tick time, we can set in TI-RTOS practically?
