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...
I am looking at using a few STM32G070 MCUs on a board and would prefer a single programming bus. As they don't have JTAG I am stuck with SWD. I know SWD protocol version 2 allows you to connect SWD in a bus with something called multi-drop. The impre...
I've been trying to get any DMA2 stream-channel (presently TIM1_UP) to update TIM1 CCR1,2, or 3 registers using a table in memory for a while now with no luck. Before adding some of my code here, I thought I would see if anyone has ever actually gott...
Hello. I have problem with linker script.I have this memory map:MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K ITCMRAM (rw) : ORIGIN = 0x00000000, LENGTH = 16K DTCMRAM (rw) : ORIGIN = 0x20000000, LENGTH =...
We are developing some devices which will use the usb as a virtual serial port to mainly update our devices with our own bootloader. Do we then need an own vid and pid for usb? Or is it also possible to get and use the vid and pid by STM?
Hi,I'm using STM32H743ZI. I want to measure the LSI frequency by timer TIM16.Configure TIM16 by CubeMX (5.2.1)"Input Capture direct mode from Remap""TI1 remap capabilities for TIM16 => "TIM16 TI1 is connected to RCC LSI"TIM16 global interrupt => "Ena...
HiI would like to create the DFU file once I compile the whole program, in a way the the file *.dfu is already ready to be updated with the bootloader. I already know that there is the program "Dfu file manager", does anyone know how to use it from c...
Hi all,I do have a problem with the Interrupt Mode of the I2C interface. I started with the example provided by STM (I2C_TwoBoards_ComIT). I do not use two boards but one board as slave and the master is an FTDI FT4222. So sending from the FT4222 to ...
I am using STM32L476.I want to enter the Stop 2 mode and use LPTIM1 as a Timeout wakeup unit.The code is written such that the LPTIM1 wakes up the MCU from Stop 2 mode after every second. The LPTIM1 takes too long to wakeup the MCU for the first time...
I develop an own LIN slave node software stack for the STM32F103RB. This stack has to pass all tests from the LIN Conformance Test (according to ISO 17987-6). This test is a customer requirement.Actually the software and/or the hardware could not det...
