I've read AN5306 and it has many helpful explanations, but it does a poor job of actually listing which selector values are used to configure each of the multiplexers - especially the mysterious undocumented one that seems to bridge around the VMSEL ...
I use STM32F407 and external NAND Flash.I modify void SysTick_Handler(void) -> add GPIO Toggle.So Normal Condition, GPIO pin is toggled regularly.When HAL_NAND_Erase_Block() excute, GPIO pin is toggle irregularly.After HAL_NAND_Erase_Block() finish...
Sup! I've tried to revive my old HAL-based project written a while ago for FW 1.6.1, fixing some minor bugs. Unfortunately, i removed old package long time ago, so i installed latest version 1.8.0. And my code isn't working anymore. After calling to ...
So does anyone know if this kind of examples for this MPU family are on the way? Or have someone done this porting and have tips for helping out with the job?
Hello,I have a project in which I use an external timer module. I want to measure the time that a function takes. I have a function say _time returnTime() which is configured in such a way that it returns a time with 10 microsecond resolution. In the...
We have a custom board with an STM32F469 and a SanDisk iNAND 7250-I 8GB eMMC. We have our HCLK set to 168MHz and SDIO clock at 48MHz, 8-bit data width. Using CubeMX (v4.26.1), the user is responsible for supplying the necessary code in the user_diski...
I am driving bldc motor using my bldc driver, I use stm32f103xx as MCU. Using 6 step commutation the control was ok, and i driven in e-scooter using my driver. But there is a small problem at starting, once the motor gets its motion it goes good. So ...
A while ago I received an STM32 discoveryboard as a gift, after I told some people on a fair that I'm a software engineer. Because I'm allready experienced in C/C++ but new to embedded software engineering, I ordered a course. Now I get stuck on the ...
during debugging i came to notice that after PCDinit() ,few instructions contating read and write on rc522, is receivng correct data through spi but after that it always read zero. same problem had been arrived earlier too but it started working on...
I have been banging my head against the wall for days on this one. I'm using STM32CubeIDE 1.1.0. I create a simple project with a SPI interface and DMA. I'm attaching the full project. I call one function: MX_GPIO_Init(); MX_USART2_UART_Init(); ...
