1.按照数据手册17.4.8.11的DMA usag里面说的 ADC触发DMA主要依赖两个事件:ADC_ FIFO_NOT_EMPTY和ADC_FIFO_ALMOST_FULL 但是我并没有在ADC里找到设置触发源的相应API只找到一个AUXADCEnableSync()函数,但是这个函数似乎不能设置成除了手动触发之外的触发方式,希望大神给我解答。 2.ADC的初始化和DMA的...
ADC DMA and PDB are configured, but there is no DMA interrupt. Please help to see what is wrong with my configuration. Attached is my project void ADC_Init(void){ADC1_Init(); PDB1_init(); DMA_Init();#if 1// Initialize TRGMUX to route LPIT0 ch0 trigger to both PDBs and PDB's...
What I want is, on the rising edge of PWM CH2 for ADC to trigger, DMA to read 50 samples (or whatever buffer size I eventually decide on. Right now it's 50) and then for the ADC/DMA to wait until the next rising edge of PWM CH2 to trigger the ADC/DMA for an...
* generated upon single PDB SW trigger. The first trigger is started by the PDB,* no delay is used. Next 3 triggers start after corresponding acknowledgment is* received from ADC.** DMA is configured to read the ADC result registers.* Within DMA major interrupt the new conversion ...
If I disable DMAContinuousRequests, does the ADC automatically trigger a DMA request every time it finishes a conversion? What if I enable DMAContinousRequests, does the DMA transfer a sample of the adc multiple times if there was no new conversion inbetween ? This is what the...
I wrote (some parts were taken from an example from this site) a code that should take sampling using ADC. I made the ADC with singel converter each time that will be triggered by Hardware trigger using pit. after each sampling i fill an array with the results u...
