Hi,I use ADC3 on STM32H7, I need to know (and set) what is sampling frequency.I use 3 channels in 16 bits. What I tried to calculate?1) Tconv_time = 8.5(setable)+8.5(fixed for 16 bits) = 17 ADC clock cycles = 17/30Mhz = 566 ns2) From this image I sho...
There was a phenomenon that booting was not possible during the low temperature test.The NRST external switch is equipped with a 100pF capacitor.The datasheet recommends installing 100nF.However, I don't think it will be a problem because the MIN val...
The USART section states that all 4 USARTs can be clocked from a common set of 4 clock sources, but doesn't reference how to specify the clock for USART4 either.
The STM32F072 Clock tree figure in reference manual shows APB1 prescaler, but where is that defined in the reference manual? When I search for APB1 in the reference manual, in the context of a register field, it does not show up (other than in the cl...
I have two boards: STM32L4xx and STM32H7xxQ.I use cubeAI 8.0.1 and tflite for a project in vision.Having set all includes and settings, I successfully build and flash my code on the first board. The second project uses the same include paths (exporte...
Shortly, cookbook says ETR frequency higher than core clock. It seems wrong. I am not sure if the information given is correct.
Hello!I am trying to connect 8 mcp23017 gpio extenders daisy chained to stm32 but I am having difficulty testing the validity of the ports. I configured the extender and set up the pins to be output pins but when I send the data to write active high ...
*Using FP-AI-Vision1 Packimport the binary webcam, the screen is black.import the people detection binary, the screen is a mess.No camera picture.While import the Tutti Frutti demo, it can normally run.
I’m using the board, motordriver IIC, to control motor through I2C bus.The chip on the board is PCA9685.The board is originally a extension for arduino UNO, and I’m using STM32F446RE which also support arduino UNO expansion connector.The official g...
