Hi,I would like to know what is max number of SPI slaves I can connect to a single SPI bus of STM32F779? I understand that using the chip select pin I can select respective slaves to operate. But is ther eany recommendation from ST that ideally , I s...
Hello Experts,I am having problem with uart on stm32h755, nucleo kit.I use uart1 and uart2 to communicate with each other using DMA.When I set the baud rate above 1M baud rate it doesn't work. Below is the clock configuration.And here is the UART con...
Hi i m using STM32H750XBH and i would like to remap SPI pin to the following pin out, i m using SPI3 full duplex master, HW NSS output, could anyone advise is this is feasible? Or i need to following the pin out from the standard H750 ioc pin arrange...
I'm bringing up a new board using a STM32H7A3. I've developed, downloaded, debugged and run lots of test programs from the VisualGDB IDE. Now I'm working on the main application. I can still develop, download, debug and run from VisualGDB but when I...
I have a question, how do I get the '.ld' link file for Flash, compared to the cmsis_device_f1 library cmsis_device_f4/Source/Templates/gcc/ directory that doesn't contain a `linker/` folder.

Hi friends from community. I have a question about the paragraph about DMA section from STM32F0x1 reference manual page 200, as showed below:I don't know how to understand the red highlight part of above picture,why there says <these ‘memory’ registe...
The schemes of a production circuit are given to me from another designer for being analyised. PCB board is a STM32F103VC based circuit.When I was looking at the bootloader circuitry scheme I saw how RS232 bus seems to be connected to the UART1 micro...
I want to be able to continuously adjust the phase of a timer output via input capture on another signal. I do not want the timer to be automatically triggered or reset by the external signal because I want some processing in the loop to determine ho...
HelloLet's assume I have a TVP5150 device connected to a STM32H7 MCU. The TVP5150 transmits PAL frames as YUV. This means 2 bytes per pixel.This results in 720x576 * 2 = 829.440KB per frame. In reality, there is pretty sure the need for double buffer...
