Hello everyone, if you can help me it's urgent.Here I have a powerful Linux board development platform STM32MP157-MINI,SOM board 1GB RAM + 8GB eMMC + integrated MCU from Alientek:https://www.bilibili.com/video/BV15U4y1E7Bh/https://detail.tmall.com/it...
Hello friends,Please, if you can really help me, I'm not an expert in the Linux device tree.I urgently need to understand the commands to execute on the device tree on the powerful STM32MP157 MINI Linux board alientek ATOMIC (Note: Chinese language, ...
Hi!! I have STM31mp157C and I want to use the ADC. I am exploring the available GPIOs and have observed that some are present in both ADC1 and ADC2.For example, according to the datasheet, PA4 can be used with ADC1/ADC2.Is there any difference betwee...
Hello together,I'm currently reading out sensor with the M4 Chip and the connected ADCs. I'm using the STM32MP157F DK2 DevBoard - The minimum requirement is to read out 3 sensors (6 is optimum) at 20 kHz each. I though of using the M4 to read out the...
Hi, I am encountering some issues while trying to configure the ADC DMA Buffer on the STM32MP135 board , when I execute the following:echo 1000 > /sys/bus/iio/devices/iio:device1/buffer/lengthecho 1 > /sys/bus/iio/devices/iio:device1/scan_elements/in...
Hello I would like to interface the STM32MP255F to high-speed ADC like AD8285 or MAX1127 using these ADC's parallel interface. Is it possible to perform such interface while using the STM32MP255F GPIO lines? Thanks.
We are using STM32MP157F in our board, running OSD32MP1 Debian SDK v3.0 (Linux Kernel v5.10-stm32mp).In our board VDDA pin is connected to LDO5 at 3.3VVREF+ and VREF- pins are connected to VSSA.We cannot supply external VREF for ADC due to hardware l...
I am trying to set up 3 ADC. I set PA4 to ADC1_INP18, PA5 to ADC2_INP19 and PF11 to ADC1_INP2. Will this be something that works? I am monitoring 3 lines (none NEED to be fast).I'm not clear on how to set this up. I am multiplexing several inputs...
Dear all,I'm currently using the STM32MP157F-DK2 series, and I'm trying to use the ADC1 and ADC2 in dual regular simultaneous mode triggered by TIM2 out event. Also, I used one DMA stream (DMA2_stream0) to read the ADC values of the Common Data Regis...
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...
