Part Number: EK-TM4C1294XL Other Parts Discussed in Thread: TIDA-00778 , LM3S8971 , UCC27714 , LM94022 , , TMS320F28027 Hello group,
I have been pondering ramifications ADC SNR by 20K pull downs near the MCU pins tied to digital ground, 6 PWM outputs. The…
HI Bob, This issue is beyond my expertise and only able to scratch the surface of what might be happening. What makes it necessary to configure GPTM4 >400us to sample along OPAMP output peaks >40mV AINx inputs? That seemed to work quite well with LM3S8971…
Back tracking reveals Stellaris LM3S8971 M3 Cortex NVIC had the very same priority grouping as Tiva M4v7 Cortex NVIC. Again very strange the exact same limitation of interrupt subpriority field bits [7:5] , though TM4C1294 has 3x the number of peripherals…
HI Charles
Charles Tsai said: . When you configure for VCO=480MHz it DOES NOT give you 480MHz but rather only 240MHz. Due to some workaround implementation the SysCtlClockFreqSet() API actually configure the VCO for only 240MHz even though you specify…
Part Number: EK-TM4C1294XL Other Parts Discussed in Thread: INA240 , LM3S8971
ADC0 30mHz ADCCLK, 2MSPS, SS2, no hardware averaging, TSHN encoding 0x0000.
Yet another odd behavior analog periodic signal is requiring 500-600us settling time or converter completely…
Hi Ralph,
Where does USB0 peripheral get it's internal power rail from does not seem an overly complicated question. If TI does not know this question who does and why is it not being properly illustrated in datasheet?
How would anyone earth trouble…
Other Parts Discussed in Thread: LM3S8971 , MOTORWARE , TM4C1294NCPDT , INA282 , SYSBIOS , SEGGER TM4C1294NCPDTi3 and older LM3S8971 MCU had similar issue though not understood why motor phase current was randomly bursting years ago.
3 PWM generators (GEN_MODE_SYNC…

Tool/software: Code Composer Studio
It would seem the ideal method of a GUI connection should not disturb the running application to merely connect with target.
The NDNR LM3S8971…
