  TM4C1294NCPDT: AIN-16 unrelated switching noise

  • Resolved

  but there are three more (AIN-17,18,19) on the end (PK1,2,3) respectively that will later be populated LM94022

  RE: TM4C1294KCPDT: ADC0 FIFO clocking array timing

  Besides the ANIx inputs PE1,2 PK0 have voltage cycling on pins when idle and active SS1 or SS2 AINx source pins float near 158mV if not pulled down via 10K, was not expecting input pins to float so high. That discovery lead to PK0 was not behaving...

  RE: TM4C1294KCPDT: USB0 device mode interrupted

  This must be the oddest USB interruption tracked down to ADC1 sequencer 1 samples of two LM94022 temperature sensors. They both were very stable at idle reporting into the USB device client. When PWM0 was crunching the DC inverter one sensor was rolling...

  RE: EK-TM4C1294XL: ADC1 FIFO results data

  Hi Bob, It seems odd that simply pinning two AINx inputs to +3v3 or GND return different FIFO results data depending on the sequencer step being sampled. Flipping the same two AINx steps GND to +3v3 and the FIFO integer results data may or may not be...

  RE: EK-TM4C1294XL: AIN16 leakage volts

  Bob Crosby . My results are what I expected, the two channels are separate. I repeated the experiment putting AIN1 to GND and AIN17 to 3.3V. The example project is attached. Perhaps your misunderstanding the conditions that exist are not full on and...

  CB1 where do you come up with nonsense capture is not real and then repost the updated capture from 1st post above. Extending thread length into multiple pages is not desired nor warranted. I think by now INA signal is not the issue, rather why does the...
