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 have a problem where even I already set the FRXTH to 1, the RXNE will automatically RESET after the SPI write data to DR register.I check using DEBUGGING MODE:In main(), I already SET the FRXTH based on the reference manual below: Then, after I wri...
Hi alli am facing a very strange issue on the MCU i have specified on the title. I am working on these devices since long time ago and i never had any kind of problem with them. During these days, i am experiencing a very strange issue: i can't conne...
I am writing a bootloader for an STM32L071CB target. In certain cases this code results in a HardFault, but in other cases it works. I know that this alone indicates that it's probably something to do with the state of the rest of my program, but I c...
Using STM32CubeProgrammer to connect to my discovery board. Connection to the board via ST-Link is lost within 30 seconds every time.things I have done:1.) Performed "full chip erase" via the STM32CubeProgrammer application2.) Selected the appropri...
Hello, I am trying to write a camera image to an SD card.I am able to write and read bmp file from PC for 160x120 sized image. However I can not read bmp file from PC for 320x240 sized image. I used below file header format. Every thing is the same e...
I'm trying to configure my custom board to only use the internal LDO, bypassing the need for the SMPS. In fact, my board doesn't even have the SMPS components. Is this allowed? The user manual seems to suggests that we can exclude the SMPS circuit ho...
the sampling logic and countig is not very standard:1) If A = rising edge and B = 0, counter++2) If A = falling edge and B = 1, counter++3) If B = rising edge and A = 1, counter++4) If B = falling edge and A = 0, counter++5) If A ...
Hi, I have a problem where my SPI SR RXNE in STM32F302R8 is never SET, causing my program always halt in while loop, waiting the RXNE status to become SET, when receive data.how I set the RXNE flag is below:#define SPI_SR_RXNE 0#define SPI_RXNE_FLAG...
