Dear all,I have a question about ADC.When i used adc in dual regular simultaneous mode, master adc can get correct value, but slave adc can not.Does anyone have some idea?These are my ADC 1 and 2 configuration.In my understanding adcData_DMA = ADC_CD...
Hi All,I have an question when i used STM32MP157.I encountered an issue when using DMA to store the values of ADC conversions.When I store the data from the ADC_DMA_Buffer to the ADC_DATA_Buffer in the HAL_ADC_ConvCpltCallback() function.Then check t...
Hello!I am using the CortexM4 coprocesor on the STM32MP157F-DK2 to measure multiple ADC channels and update a control loop based on the values. I have set up ADC1 using the DMA2 in circular mode to read channels IN1, IN2, and IN4. I have a buffer set...
Could someone point me to some documentation about how to control the oversampling for ADC1 and ADC2 for the STM32MP157C? Using OpenSTLinux 4.1.0, buildroot. I looked around but couldn't find anything. Thanks!
Hi I have problems with our custom board bringing up the VREFBUF. I eddited the devicetree as follows (also in U-Boot).&vrefbuf{ status = "okay"; compatible = "st,stm32-vrefbuf"; reg = <0x50025000 0x8>; regulator-min-microvolt = <2500000>; regul...
Hi,Does anyone know how to enable dts and driver for ANA0/ANA01 ? We tried normal ADC and they are working well but can't find where relates to ANA0/ANA01Many thanks,
On STM32MP1, how to use the internal temperature sensor, ADC2_INP12 and internal factory calibration?Any example?Is it possible to access these data via A7 or just on M4 ?
I am trying to read data using ADC1 continuously and copy it into a buffer via DMA.However, the data is only read and copied once (seemingly correctly), and afterwards nothing happens anymore (data in buffer does not change, ADC1_IRQHandler() is not ...
I have to read ADC readings from 4 channels on both ADC1 and ADC2. In production mode, when OPENAMP isn't enabled, everything works as expected; however, when it's enabled, two channels are getting garbage readings. I do not know why or how to fix it...
Hello every one I am starting with the STM32MP157, and i wonder if there is a schematis that i can follow that doesn't require the use of external DRAM or any IC meaning without (linux) using bare meatal code through the IDE. just to operate the ADC ...
