Way to denote row addresses of NAND flash may be wrong

2024-09-09
I am using STM32CubeH7 from GitHub (the latest commit is here). In stm32h7xx_hal_nand.c, I found something starting at Line 582:   if (((hnand->Config.BlockSize) * (hnand->Config.BlockNbr)) <= 65535U) { *(__IO uint8_t *)((uint32_t)(...

STM32H743 Output of ADC on multiple channels with DMA is abnormal

2024-09-02
I am trying to use ADC with DMA on STM32H743XI. I set up ADC1 IN7~IN9 and use three uint16_t to store their converted values. I use DMA2 Stream 0 to transfer data. CPU ICache and DCache as well as MPU are disabled. ADC Clock Mux is set to PLL2P 50MHz...

scanf() can only read one character

2024-08-28
I am trying to use scanf() in STM32H743, referring a webpage (here). More specifically, after setting up USART1 in STM32CubeMX, I add some function prototypes like:   #ifdef __GNUC__ #define PUTCHAR_PROTOTYPE int __io_putchar(int ch) #define GETCHAR_...

STM32F407 PWM output not stable

2024-06-24
I am trying to set up PWM on Channel 1, 2, 3 of TIM3. At first I set up only Channel 1 and the output voltage of PWM is 2.8V. But after I set up the other two channels, the output voltage of Channel 1 & 3 gets to 3.6V, while that of Channel 2 is stil...
