LCDHi all. I can’t figure out how to work in LCD interface mode. I check it with an analyzer and see that when writing a byte, instead of one FMC_NWE pulse, several are generated.

When using the delay function, I encountered an incomprehensible manifestation, for verification I brought a signal to the output of the microcontroller and received a switching frequency two times lower. I checked SystemCoreClock, it shows the confi...

Good day. Faced such a problem. I wrote a loader for a non standard board, using stm32f476vgt MK, N25Q128A memory in extended SPI mode. All functions are tested in debugger mode. The data is written correctly, the memory is erased correctly, but veri...

Microcontroller stm32f030f4p6 is defined but not flashed in CubeIDE 1.11.0. It gives the message "The microcontroller is not original", while the CubeProgrammer flashes it perfectly, correctly determines the ID 0x444 Rev 1.0. If I try to flash it, it...

when trying to write the firmware to the flash of the controller, an error is displayed that the program cannot connect to the flash. At the same time, the CubeProg controller sees, reads, flashes. In Keil ver. 25, everything is fine, in older versio...

Well, how would it work out. Described the region in CORTEX M7 with full accesscreated a definition by defining the address on line A16 (R/S signal) #define ADDR_CMD *(uint16_t*) 0x60000000 #define ADDR_DATA *(uint16_t*) 0x60020000 and received...

Should this be done in the CORTEX M7 section? But I have difficulties with this, I do not understand this part of the kernel well.

If I understand you correctly, the data format in the function and in the FMC node itself must match. If FMC is 16 bit then #define TFT_DATA *(__IO uint16_t*) 0x60020000This happened with the F7 series, but not so with the H7...

The fact of the matter is that the solution from ST solves the problem of unstable delay duration and it remains in any case of a back-to-back duration. Well, unless, of course, you consider the code where there are several interrupts missing and you...

Ok, sort of figured out the new delay solution. It monitors the number of core ticks, and even if the microcontroller goes into an interrupt, upon exiting it, the function reads the state of the tick counter and adds them, taking into account the mis...

What's wrong with FMC seventh family

Problem with the delay function in the library for STM32H7B0

The external loader works correctly, but the reading in the Cube Programmer is not displayed correctly.

Microcontroller stm32f030f4p6 is defined but not flashed in CubeIDE 1.11.0

In the CubeIDE 1.7.0 development environment, I encountered a problem while recording in a flash
