STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
I am trying to figure out why the state of GPIO pins are changing after entering Stop2 mode. I've got an ADC chip connected with Reset lines being held high by GPIO pins configured as push-pull with pull-ups enabled. When the device enters Stop2 mode...
I’m using CubeIDE and I want to internally connect peripherals to the comparators. This doesn’t appear to be supported by CubeIDE, but I’m wondering if its still supported by hardware somehow.I’m using an STM32G4 and I see that COMP6 INP lands on PB1...
The maximum HCLK of STM32F407 is 168MHz, while the calibration value of Systick is 150MHz HCLK. What is the reason for setting the calibration value of Systick like this? Why not set the calibration value for Systick based on 168MHz HCLK?
Hi, I'm currently using the STM32U575 to develop a product, and my clock configuration is set to the maximum of 160MHz because I'm dealing with a large amount of data. I have two SPI channels collecting data at a sampling rate of 20kHz, with each sam...
Hi,We were using CubeProgrammer on Windows to program our MCU in DFU mode and everything was moving well until we noticed MAC does not detect USB in DFU mode.So, I am wondering if there is something we are missing to do which the MAC operating system...
Hi all, I need to generate a DAC output which is operating on 2 quadrants and the quadrants may be asymmetrical with respect to both the duty cycle and the amplitude. Attached a picture which better explains what I need. MCU STM32F446RE DAC OUT1 on p...
Hello,I have a problem on a STM32H753 which I do not understand.I want to sample some data from ADC with a given time period.So I use the TIM2_TRGO as Event generator for the ADC3 (via EXTSEL)ADC3 is configured in 12 Bit single conversion, in the seq...
Hi，I am using the PWM1 mode of the STM32G031 TIM1 and I noticed that the rising and falling edge time of its PWM output is about 20 ns. I have used the PWM fast mode but this time is not getting shorter. I would like to know if this time is normal? B...
Hi Community,During a project we are using the microcontroller STM32H7B0RBT6 with QSPI PSRAM APS6404L-3SQR , it works fine in indirect mode either in quad read and quad write, but the issue is with the write in memory mapped mode when trying to write...
Hello Team,Want to use systick timer for time base of 1uS without interrupt. Please help me on this to configure it without interrupt. Regards,Sachin N
