I recently got my STM32F407VG uC working with UART4. I can receive a byte and send a byte. Though I have been reading on how to acquire more than one byte at a time. It seems as though people like to use DMA. I am perfectly okay with polling for my e...
In the capture/compare ISR, I want to program the next CCR1 value and the associated action: to change the output to active or inactive when CNT matches CCR1. For this I need to set TIM1_CCMR1 OC1M to 0001 or 0010. However, as soon as I program OC1M ...
On a new product we plan to use an STM32U5 MCU to manage a Wireless (WiFi/BT) module and a micro SD card.As the Wireless module has an SDIO interface we have to use the both SDMMC interfaces of the STM32U5.Does anyone has already done this kind of st...
Hello,I have been trying out interfacing the STM32F407 Discovery Kit with different sensors but while trying to Interface a SPI uSD card adaptor containing a 16GB microSD card, the interfacing doesn't seem to work out at all.I have followed all the d...
i'm trying to take AD value with DMA when HRTIM TIMER A counter is equal to periodI tried using TIMER B and set to call interrupt when its counter is equal to period (TIMERA and TIMERB setting is equal)but when i checked with Oscilloscope it sh...
Immediately after power-on, but before my main gets to initializing the GPIOs (HAL_GPIO_InitGPIOX->MODER = 1 // Output Push PullGPIOX->BSRR = 0 // Set Pin LowGPIOX->OTYPER = 10U // OutputGPIOX ->PUPDR = 2U // Pulldown)I see the pins (ex. PJ2,PJ3, etc...
Hi : we notice both HSE or HSI could be used to supply system clock. what is the difference between these two options? and which one should we use in our product? and, for the power consumption, if we connect external crystal, then choose HSE ...
