In debug mode, I see the following on CM7: At the same time I see the following on CM4: How is this possible if I have turned cacheability off?MPU_Region_InitTypeDef MPU_InitStruct; /* Disable MPU */ HAL_MPU_Disable(); // Configure SRAM2 as non-c...
I am continuously calling HAL_UART_Receive_IT(), until i get some specified value in receiver buffer. But after some time HAL_UART_Receive_IT() return BUSY and after that it is not receiving any further interrupts and seems like the code is dead. H...
Hi, What are the revisions of the STM32F411CEU6 chip?The ERRATA doc from STM mentions only revision "A" . Are there other revisions?I received board with revision "1" .
Hello,Do you have schematics suggestion for using a microSD on the SDMMC interface of the STM32L476? The reference manuel only shows data with 8 lines while the microSD has only 4 lines with data3 share with card detect.Do I only need to ignore the c...
hello dear. I opened the documentation for stm32H7xx and am trying to calculate the address. I don't understand what it means?Address offset: 0x3DCh-0x3EChwhat should I add to the base address?0x40017400how to understand and read it?Address offset: 0...
Hi Team,I have tried using kmenuconfig and bmenuconfig, didn't find the tool. And other way i tried to install using github, but didn't succeed. Can you please guide me.Waiting for your response.Thanks in advance.
I'm currently trying to learn about how the HAL blocking functions of I2C works on the STM32H7B3I-DK. However, the master device fails to receive any data unless HAL_I2C_Master_Transmit() is called before it.For example, the following code doesn't pr...
Hello all, I am using keil uvision to direct download the code in a STM32L552MEY6P MCU. My code just toggles a pin. The MCU is connected to a V3 programmer using SWDIO,SWCLK,NRST,GND and VCC. Every time I program with Keil, I am not able to initiate ...
Hello.Is there a complete course or book from start to finish for beginners on new ST programs? I want to switch from arduino.I found the book Carmine Noviello Mastering STM32, but it is old (2017-2018) and it uses an eclipse. I want to find a full-f...
I need to collaboratively program an STM32F722ZET6, but do not have in-person access to the chip, and I can't find any development boards online that use it. I'm new to this, so I don't know how similar a stand-in must be for me to be able to confide...
