Posted on June 27, 2018 at 11:24 hallo, i am trying to program the ADC in the STM32F415ZG. I use the hal library and have written interface functions and modifications to adapted it to my application. I have tried out the dma and the Interrupt dr...
hallo,my problem is to understand how affects an event all following receptions. My SPI-signal quality is good. But wether a wrong Byte-signal is detected according to noise or a single spike this may results in a wrong data reception only of this by...
Posted on June 29, 2018 at 09:01hallo AvaTar,thanks for the hints. I will look for this.by the way some introductions of the code: the function ADC_Start () sets the GPIO-Signal and starts the ADC Conversion in Interupt mode. The function HAL_ADC_C...
Posted on June 28, 2018 at 17:40hallo AvaTar,of course this command have some cycles but not the time of 5 or 6 mikroseconds. The call is from the ADC-ISR. Its very close to the detection of adc conversion finished (EOC). With the system cyle time ...
Posted on June 28, 2018 at 12:04hallo,thank for the reply.A correction: ADC-CLK is 21MHz and not 24MHz; (SYSCLK=168MHz; APB2-dvider=2 -> PCLK2=84MHz; ADC_divider =4 -> ADCCLK=21MHz)Here is a Code snippet from the ADC-functions.The switch ADC_DMA is ...
Posted on June 27, 2018 at 16:30hallo,i have read this. But with 12Bits resolution with 15 ADCCLK cycles and 24MHz the conversion time is 0,625 mikroseconds. I measure more than 6 mikroseconds. There is a big difference??best regardsEd
