Per the title, I'm using USART2 with DMA transfer but for some reason the line stays LOW (active) before/after transmision.Init code is pure HAL generated, I added a "DeInit" just to make sure the UART enable wasn't persisting between resets/debug se...
I wonder whether I can connect two quad spi ap memory to the same octospi interface on stm32h730 to double the bandwidth. Or such a configuration can only be used with nor flash, not psram. Thanks.
Hello,I created the project in STM32CubeMX 6.3 with the board name at default settings. The generated code in STM32CubeIDE has many related init functions. The below MX_FMC_init function didn't have any issue and bank2 was set automatically. Accordin...
I am using the STM32G484 microcontroller to output twelve high resolution PWM signals with the HRTIM timer module. All timers have the same constant period and and the CMP1xR and CMP2xR registers for all six timers are updated after every repetition ...
Hello everyone,I am having a very strange problem with respect to SPI6 and I am hoping someone can give me some direction. I have configured the SPI6 to be in SPI master mode and I am continuously reading data from a sensor. Everything looks to be f...
I am getting compile error in a lot of HAL files (gpio, rcc , spi). The error is for registers and peripherals which are not present in F407 but are present in F42/43 like. Since the HAL files are common for whole F4 series, these regs and functions ...
I tried to change SPI1 to SPI4 in the LL example code.My problem is I cannot detect any signal on the CLK or data pins.void Configure_SPI4_DMA(void) { /* DMA2 used for SPI4 Transmission * DMA2 used for SPI4 Reception */ /* (1) Enable the cl...
Hello, is there any way to use EXTI simultaneously in different ports with the same pin number?Examples for MCU STM32L071CB:Using PA4 and PB4, orUsing PA10 and PB10, orUsing PA6 and PB6, and so on
Android version fails to connect with "error during the connection with the node XYZ". I have tried both latest version available in Google Play Store (v4.14.7) and the other version (v4.14.4) available on ST Micro website. Does anyone have solutions...
HAL_PWR_EnterSTANDBYMode() will still wait properly, but HAL_PWREx_EnterSHUTDOWNMode() will immediately return to RUN mode.What do you think is the cause of immediate wakeup?As shown below, the only code difference is whether to enable HAL_PWREx_Ent...
