Hello, I'm a little confused about the SPI communication. I tried to get the MCP2515 working with the STM32, but I end up at the beginning because I can't read data from the SPI. Both the HAL_SPI_TransmitReceive and HAL_SPI_Receive functions give me ...
Hi,which STM32 dev kit (preferably STM32L4 family if available) has a MicroSD card reader that uses standard SPI (i.e. not Quad SPI)?Also is there a selection tool that allows you to specify the type of SPI or at least whether it has Micro SD? Thank ...
For the STM32G47xxx microcontroller, the transition to the system bootloader is fair by changing the optional bits or by transitioning from the user space. Setting the required optional bits forces the use of a programmer and something like St-Link U...
Hello,I’m not sure that is this important, but the board I’m using is the STM32F413ZH. When I try running an application on the STM32, it generally works fine, but sometimes after exiting debug mode, it stops working. Actually, this isn't a big probl...
When I connect to my computer with a USB connection to upload the code to the nucleo-f446re board, that part of the board gets very hot. I didn't forget to jump to the U5V all the time when I connected to the computer with the USB. Why does this happ...
Hi, what is the difference between .elf file and .bin file to program STM32. If I load up the .bin file and program STM32, will it contain all the necessary such as program data and flash data. Is there a application to program individually the .bin ...
Hello can anyone please help me with the SWD pin status. What can be the expectation?
Hi,I have Nucleo-H743ZI2 and Nucleo-U575-Q boards.I can see that we can upgrade the st-link firmware for STM32 boards via STM32CubeProgrammer, ST-LINK Utility or STSW-Link007 tool. But I have observed that this will always pick up the latest version ...
Hello, I am following this application note an5496-guidelines-for-the-buck-voltage-mode-on-the-bg474edpow1-discovery-kit-stmicroelectronics-1.pdf for the B-G474E-DPOW evaluation board. My problem is I can not change the load bank using the joystick n...
Hi everyone,I am trying to run an ethernet phy (LAN8742Ai) using STM32H745. I can say that there is no major difference from the Nucleo ref. phy design. However, when i ping, i cannot get a response and the processor gets very hot. The phy and MCU bl...
