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 ...
Hi everyone, I need the lowest possible current consumption for my project. I need to power my MCU with external supply. Currently I have a Nucleo F401RE, which is not so good for low power applications it seems. It's connected to a X-NUCLEO-NFC04A1 ...
We are using STM32L151RBT6A device. As per the specification we should be able to have access to 80bytes of RTC backup memory , but we are able to access only 20bytes of Backup registers memory. As per RTC backup registers description , for value li...
