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...
OTP portion of FLASH is a valuable asset in some STM32 families and represents a convenient place to store things like security keys. For this, it is desirable - and, as it's part of FLASH, also quite logically expected - that setting read-out protec...
When switching on a new, unprogrammed STM32L431, PA6 turns hard to output high.This is SPI1 MOSI.AN2606 should say this out aloud.I know the 'G0 have this too, and AN2606 says this for them, although quite quietly and confusingly in a footnote.There ...
I will be using 16 channels of STM32 ADC and I would like to protect them against overvoltage and ESD (those will be used as device inputs and unwanted situations can happen), my initial thought was to use a Zenner diode array and current limiting re...
Greetings!I generate periodically a 10MHz PWM signal of 8 pulses. The PWM signal has high polarity so the first edge is falling. I need to generate an interrupt/event on the rising edge that'll signal DMA to move data from a GPIO IDR to a data buffer...
Hello,I am working on a STM32L073V8T6. I want to use the 1/3 bias functionnality to manage a screen.I have configured the contrast control to 3.26V, the Mode to 1/4 Duty Cycle and the Bias Selector to 1/3 Bias. But if I write something to COM0 and...
Hi i am working with stm32l051c8t6 , i am using wakeup pin 1 to wakeup from standby mode, weather is that possible to make the wakeup pin should act as wakeup pin and also as external interrupt, it should wakeup when an external interrupt is detected...
I need to declare a 'volatile const', meaning that the value is placed in FLASH and that it is re-read every time it is referenced (as the FLASH is written to elsewhere), but am finding it very difficult to accomplish this as the compiler either plac...
Hi,I have custom developed board that uses STM32F401RCT6TR as MCU. I have LSM6DSLTR IMU sensor on the board and MCU is communicating with IMU using I2C1 channel (PB6 and PB7). I also have 2.4" screen (ILI9341) that displays IMU values and external EE...
Hi All I'm new to STM32 and I'm exploring it a little bit. I think I've found an issue in the HAL in configuration Line is referred to the external interrupt line to be connected. it is configured in the BSP with (void)HAL_EXTI_GetHandle(&hpb_e...
STM32F769I Disc：Is the function of stm32f769i dico's QSPI DDR normal?When I used the ddr mode, I could send data using 1line, but when I used 4line, the device was busy until the timeout error occurred, and the data could not be sent normally.However...
