Part Number: EK-TM4C1294XL Other Parts Discussed in Thread: INA240 , TM4C1294KCPDT , LM94022
Some things become clear CH16 on two different external analog input uses have voltage coming out PK0 pin 18 when ADC0 SS1 or SS2 is being active with PWM0. We avoided…
Part Number: TM4C1294KCPDT Other Parts Discussed in Thread: LM94022 ADC1 Sequencer 1 AIN16 (step 0) FIFO rolls mixed hex values compared to very quite AIN9 (step 1), both have sensor LM94022. Reversing sequencer steps moves the noise to AIN9 step 0 , proving AIN16…
Part Number: TM4C1294NCPDT Other Parts Discussed in Thread: LM94022
The gremlins seem to get more active when potentials around the ADC channels are elevated above 24v. The very last channel scanned (AIN-16) for conversion appears to spit out perhaps VREFA+ potential…
Part Number: TMDSICE3359 Other Parts Discussed in Thread: LM94022
Hello,
I am trying to read the temperature sensor (LM94022) value and display it on the CCS console. I tried to compile the sample code in C:/ti/pdk_am335x_1_0_6/packages/ti/starterware…
Part Number: EK-TM4C1294XL Other Parts Discussed in Thread: TM4C1294KCPDT , INA240 , LM94022 Very odd things are occurring when SS1/SS2 FIFO's names from ADC1 module are configured as SS1/SS2 FIFO's for ADC0 module even though both exist at different base…
Hi Charles,
I checked the call code via calculator and N << 4 is correct as it subtracts 1 from N passed in from the call for REG 66 value. But who know what the integer N does to the ADC modules clock as very little info in REG 66 text to explain how…
And no ideas why AHB seems to back up only when PWM generators are driving PWM output control block? Look again last post made edit to the match count load INT handler source SS1, yet another GPTM does load SS1 trigger processor in 10ms intervals. Fan…
Hello,
Thank you for your inquiry. We do not have specific maximums for the rows you pointed out, thus it would be +/-2.7C. If you are looking for better accuracy please check out the LM94022. The LM94022 is a drop in replacement for the LMT86.
Thank…
Hi Charles,
Correct SS1 of either ADC module are not being configured for differential AINx inputs. That does not mean differential configuration in not occurring via some other unknown or undetected reason. Results might go unnoticed if differential mode is…
Hi Charles, Using Tivaware PWMGenIntTrigEnable() only GEN0 would trigger ADC1 and GEN1 not via (PWMTrCntLoad) alone. ADC1 SSn sample end INTS are working ok. Albeit ADC1 trigger sources set above GEN0 did not have any effect to trigger SSn. Have never…
