How to use printf() to output to UART

I have been using printf() to output to UART for many years on a STM32L052All these projects still compile and printf() to UART, no problem.I started a NEW project with CubeMX, but now printf() does NOT print to UART.I use the same int fputc(int ch, ...

MT29F128G08 NAND FLASH with NUCLEO-L496ZG basic driver help

I am not much of a software/firmware developer, but i need to get a basic Driver working for NAND flash device "MT29F128G08AJAAAWP-ITZ" working on a "NUCLEO-L496ZG".I have the device wired up to the eval board, and need to build a basic drive to writ...

What is the correct maximum FMC clock on a STM32F767 ?

Hi, I am currently working on a display driver board, with a STM32F767. And I would like to use the FMC with a SDRAM.My problem is that the MCU is clocked at 216MHz, the SDRAM max clock is 133MHz, on the F767 documentation, it is written that the max...

Is there any board which can support more than 30 MHZ Toggle frequency on GPIO and Parallel processing.?

Currently we are using Nucleo F746ZG controller with 216 MHZ frequency.We are able to get high toggle frequency on GPIO with this board.Now we want to shift to Micro Processor for parallel processing.So is there any Better Controller/Processor availa...

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...
