STM32 MCUs Products

In the process of finding a suitable MCU for a medical device, I find it hard to distinguish which of the MCU's are FDA approved and which ones not. Are there any especially good MCU's that are really robust and officially approved?

UART+DMA sends data disordered or resends it. Is it a variable type problem?

Hello!I'm working this UART+DMA with idle detection and ring buffer. My STM32F4707VET6 receives data from a sensor and then sends it by USB, the data received by USB should look like this:$1651500,-5,-228,-988,-3,-217,-976,-102$1651510,-4,-228,-987,-...

HAL I2C library returning HAL_ERROR even though communications are succesfull

I am using the STM32F746VET6 with a project generated using MX v6.5.0.I am using interfacing to several I2C chips in my project and they are operation correctly. When I started checking the return values from the HAL_I2C_Master_Receive() function, ho...

g051 serial problem

HiI have made a board using the g051k6 chip. I have not been able to receive data from another board sending data at 115200 bd. I connected another serial port to the input pin , and all data is received without errors. A uart problem is mentioned...

stm32f303rc: SRAM parity error bit NOT SET, but NMI is taken

SRAM parity check is enabled. In fact, breakpoint in NMI is reached.But SYSCFG_CFGR2.SRAM_PEF bit is NOT set. See .png.Disassembly (at bottom) shows, that address of CFGR2 is loaded at R0 ("Registers" to the right) and its contents is loaded to R1. T...
