Hello, I have written a Flash bootloader for the STM32H743 for our custom application PCB. In a nutshell, the flash bootloader check an external flash memory IC with SPI on the custom application PCB if there is a new image to be flash and do it if i...
I am stumped and frustrated. I wrote some test code to test UART4. It worked fine. Then I moved the test code over to my main project and now I get no UART interrupts. Both code sets run on the same hardware. I have checked to make sure the UART RX w...
Good day folks, I trust you are well.I am interfacing with a APMemory 256Mbit RAM (APS256XXN-OBR) via the 16 way XSPI.The RAM registers can be configured correctly at 100MHz, as well as the whole 256 Mbits can be accessed via Mmap.For Configuration I...
Hello There,I am working with Matlab 2022b & I require stm32 MAT target software for a project on simulink. This software was free earlier back in 2022 but now it has become obsolete. I am not able to find it even on torrents websites. If you have i...
I have a custom PCB with the STM32G431 microcontroller and ESP32 controller. ESP32 is connected to STM via GPIO pins in order to perform firmware upgrade using STM32 bootloader protocol. Connection are as follows:ESP32 UART TX <-----> STM32 UART RX (...
Some confusion about the configuration of output compareHello, I am a beginner in STM32 MCUs. The MCU I am using is STM32F103ZET6.I'm trying to use the output compare function of the timer.But I came across something that confused me.I use STM32CubeM...
Hii, I'm new to embedded systems. I have the B-G474E-DPOW Discovery kit with STM32G474RE MCU and I implemented the peak current mode Buck converter(HW) as described in the application note of stm. The only thing that I cannot understand is how exactl...
Hi everyone,we are moving our design from usb full speed to usb high speed using STM32F76VI.We want to use the suggested module STULPI01A in order to achieve this.On datasheet is specified to use a precise reference clock.Since our application use a ...
Hi, We are designing a low power design using STM32U5A9NJH6Q. As it is low power we aim for lowest possible consumption.We are not using USB on the device; hence we would like to omit any consumption from the VDDUSB and would have connected it to VSS...
Moved from MPUs forum.Hi, i must Use a Single Port Gigabit Ethernet PHY that have a RGMII Gigabit Interface to connect a RMII 10/100 MbitEthernet MAC interface of the STM32H563VI MCU. Do you think it is possible to connect a Gigabit PHY chip to the ...
