728x90 반응형 2823x3 [TMS320x2833x, TMS320x2823x] ADC - #1 TMS320x2833x, TMS320x2823x 28335 _ ADC part from Technical Reference Manual * ADCTRL1 register _ SEQ_CASE bit → Sequencer operation ① 0 : Dual-sequencer mode : SEQ1 and SEQ2 operate as two 8-state sequencers. ② 1 : Cascaded mode : SEQ1 and SEQ2 operate as a single 16-state sequencer(SEQ). SOC trigger in dual sequencers : for SEQ1 _ Software, ePWMx SOCA, External pin for SEQ2 _ Software, ePWMx SO.. 2023. 3. 9. [TMS320x2833x, TMS320x2823x] PIE _ "ADCINT" interrupt In this posting, I'm gonna check how to use "ADCINT" interrupt. 28335 In TMS320x2833x, TMS320x2823x, There is PIE(Peripheral Interrupt Expansion) vetor table in Technical Refrence Manual. In this table, the priority of PIE interrupt is explained. PIE vector table is compesed of 12 groups and each group has 8 interrupts.. As you can see, there are 3 ADC interrupts. ADCINT, SEQ1INT, SEQ2INT All of.. 2023. 3. 9. [MCU] Acquisition Window Size (width of SOC pulse) in ADC TMS320x2833x, TMS320x2823x TMS320F28335 28335 technical reference manual 에서 ADC 관련 부분을 보다보면, "Acquisition window size" 라는 말이 나온다. 이 말은 "width of SOC pulse" 라는 말과 혼용되어 사용되는 것 같다. 아무튼, SOC(start of conversion) 펄스의 폭... 이것은 ADCTRL1 register의 ACQ_PS bit 에 의해 결정되는데, 이 폭을 왜 결정해야 하는걸까? [ADCTRL1 register _ ACQ_PS (11-8 bit)] - Acquisition window size - SOC pulse의 폭을 조절하여 샘플링 스위치가 닫히는 시간(구간)을 결정함 - SOC p.. 2023. 2. 23. 이전 1 다음 728x90 반응형
