Hello Geeks
I'm new bie with at STM, I need to read at-least 3 adc channel of STM32L152RC having interrupt
I've used Cubemx and generate the code having property of
scan->Enable
No of Conversion->3
Global interrupt ->Enable
Rank from 1-3->48 cycle Sampling rate
Now the problem is when i compile and load the code on MCU then it's working and shows 4095 Samples for 3.3V attached at IN0 but this result is same for all first 3 channel! it means all remaining 2 configured channel shows 4095 samples even they are floating!
here is the debug logs
ADC_raw[0]--->4095 ADC_raw[1]--->4095 ADC_raw[2]--->4095
-----------------------------------------------
ADC_raw[0]--->4095 ADC_raw[1]--->4095 ADC_raw[2]--->4095
-----------------------------------------------
ADC_raw[0]--->4095 ADC_raw[1]--->4095 ADC_raw[2]--->4095
-----------------------------------------------
ADC_raw[0]--->4095 ADC_raw[1]--->4095 ADC_raw[2]--->4095
-----------------------------------------------
ADC_raw[0]--->4095 ADC_raw[1]--->4095 ADC_raw[2]--->4095
In short I'm not Sensing individual channel and result remain same for all 3 configured channel!
here I'm attaching CubeMX project with Keil MDK5
any one help me here?
All Suggestions welcomes
Thanks
