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...
We are trying to build MCU application that require wakeup from standby mode using wakeup pins. MCU we are using STM32L412KB and it consists of 2 wakeup pins on PA0 and PA2.As per figure 3 we want to connect PA2 wakeup pin to USB V sense to wakeup us...
I am using STM32F7508-DK kit and Using I2C as a slave whereas ESP32 is a master, By using HAL_I2C_Slave_Receive_IT and HAL_I2C_Slave_Transmit_IT API I am able to do one way communication either read or write, but in my application I required read and...
Hi all i dont know what happen to the i2c line just after the address acknowledgement the SCL line goes LOW while SDA high and after that if i am sending data through data register I2C1_DR there is no response.Point to note that that if i initialize ...
Hi,I suddenly get this kind of interrupt in a code that was previously working perfectly. The instruction that makes this interrupt arise is *dst=*ptr. You can check below the function:void readHistoryFile(unsigned short * dst){ unsigned short * ptr...
I refer to the attachment. I am using a push button to power on a STM32F303. As soon as the push button is pushed a P channel FET is activated supplying voltage to the STM32F303. As soon as the STM32 starts it activates a pin which takes over activat...
In the stm32H750 reference munal, I can see the details of fdcan interrupt, mostly by config registers (FDCAN_ILS, FDCAN_ILE ), but I didn't see the illustration about which interrupt signal(like tx complete ) occurs in which interrupt line(line ...
Hello,Is it possible to use uart with dma, so that on idle we also get informed, so that we can read the rx data ?I found no example in hal cube for using UART with DMA in such "real life" scenario, only in simple full buffer fill - which is not prac...
I'm trying to teach myself C++ on STM32. Unfortunately the books on C++ I have and most websites I found do not mention interrupt handling. The websites where it was explained (embedded.com, stackexchange.com, etc) did it in a way I simply do not (y...
Hi sir/madam,In the datasheet of STM32H750XB 57th page J1 pin name is given as PH0-OSC-OUT and in 61st page the same pin is given as PH1-OSC-OUT. which do we need to consider?Datasheet: https://www.st.com/resource/en/datasheet/stm32h750ib.pdf
