Multiple ADC sample with different frequency interference
Hi,everyone.I'm use NUCLEO-L496ZG platform.ADC1 sample at a frequency of 5M,ADC3 sample at a frequency of 12.8K(PWM trigger).when only run ADC3,ADC3's waveform is normal.when ADC1 and ADC3 run at the same time,ADC3's waveform has a lot of interferenc...
Resolved! ADC1_IN16 (no mode)
I begin a new project I want to use the PA12 as a ADC input. But the pin is orange and I am unable to activate the mode or channel of the ADC.What is the explanation behind it? How do you explain it?Thanks a lot to all.
STM32L476 Changing VRef for ADC precision
Hi I want to sample low voltage signals with STM32L476 so I figured it would be a good option to reduce reference voltage and I found this part in the MCU datasheet: Now I am using ADC in dual mode and sampling 8 bit so it is not too precise for low ...
adding CMSIS-DSP library to stm32h743
hi,I want to use CMSIS-DSp library in my stm32h743 project. the project contain USb MSC device also.After adding the library to project i am getting 5 errors, which I am listing below,11:56:50 **** Build of configuration Debug for project DIN_MAIN_V3...
How to recovery CAN communication after STM32H5 entered into CAN bus-off?
Hi, I found that when STM32H5 entered into CAN bus-off, it couldn't recovery CAN communication by itself. And there is no "Automatic bus-off option" for this MCU. I have read the MCU Manual to know related registers about CAN bus-off for this MCU, bu...
Resolved! Abnormal GPIO Operating Frequency on STM32H743IIT6
Dear Support Team,I am encountering an unexpected issue with my STM32H743IIT6 microcontroller where the GPIO operation frequency observed via an oscilloscope is only 16.6 MHz, despite configuring the bus clock at 400 MHz and AHB clock at 200 MHz. ...
Cross Reference
Pls cross TI part number TMP75AIDGKR (Temperature Sensor With I2C and SMBus Interface) Previously there's a Cross Reference tool in ST website but it's gone. I use it regularly. I hope it can be reinstated.
Resolved! QSPI external RAM
hi all,i was trying to work with stm32u585 microcontroller and an external RAM IS66WVQ2M4DALL , which is a QSPI based RAM can work in 133Mhz.the RAM support DDR based data transfer. Here i am attaching my OSPI configuration hospi1.Instance = OCTOSP...
800 x 800 Display with STM32U5G9VJT6Q - possible?
Hi,we are trying to get a 800x800 display to work with the STM32U5G9VJT6Q, using either RGB888 or RGB565 in Video Mode (Burst).According to what we read it is definitely possible. Did we miss something?Could someone please confirm that is definitely ...
