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...
Hello, I am working on STM32H7 series controller, I have to continuously reading the data of dac through spi and vtg ,and send over an GUI application so every 50 microsecond I have read the values of 6 spi , so I have do the calculation in stm32 or ...
Is the STM32F43x under any import/export regulations, if you want to export a product with F43x to china? Because for example china has theyre import and export list for crypto devices. Or in regard of Wassenaar Arrangement? Even tho our product does...
I have a STM32L081KZT and I am using the LPUART.I want to create my own Interrupt (handler) based on UART_FLAG_TXE. So basically a function that gets called whenever the UART_FLAG_TXE bit is set.In the GCC compiler manual I have found this:void f () ...
I can't get a data transfer over the SPI bus with my currently implemented code. I can see the CLK and CS but there is no output via MISO (only zeros are probably transferred). If I execute a transmission manually via "LL_SPI_TransmitData16", I can s...
I've spent the last 2 years developing a product using an STM32F103, but I've recently discovered that the ones I've been supplied with are fakes, which have a tendancy to blow up :( It seems as if no genuine F103s are available now, so either I have...
We have a very simple, blocking, UART transmit routine, which writes a byte and waits for TXE to become active. Every so often, and I mean something like 1 in 100,000 or more calls, it gets stuck at line 3 of the code pasted in below; TXE never becom...
I am starting layout with a STM32H745B (208 LQFP) next week for a core part of our new product line. I need a small quantity for prototyping - 10-20 or so.Distributors are showing 52 weeks delivery for this and all H745 parts. Every version of H7 is ...
