How to enable interrupt with registers

Hi,I have seen that to enable the interrupt for a given peripheral we must enable the correct bit in the peripheral registers (e.g in the DIER register for a timer) and then call the following functions (e.g for peripheral timer3)  NVIC_EnableIRQ(TIM...

STM32H7B3LIH6QU and DAC1_2 in conjunction with sdram (1) and usb_HS

I am so close to finishing the project but have one last BIG problem.I need DAC1 Ch2 - either exposed on PA5 or on the opamp2 vout PE7. However, the usb hs ulpi clk cannot be moved from PA5 and the D4 data line cannot be moved from PA5. Other than m...

Nucleo-F410RB DAC hardwired to a (green) LED ?

Friendly greetings !i had found, ordered and canceled the board with the perfect MCU.M4ADCDACDSPAnd more, but I really wanted that DSP and DACI install STM32CubeMX on my Mac M1 (with some troubles at first, but it works).I select the board I just ord...

Problem with GPIO interrupt, MCU ignores the mode selected.

Here's my GPIO setup:/*Configure GPIO pins : P_H_IN_Pin PCA_INT_Pin P_L_IN_Pin */ GPIO_InitStruct.Pin = P_H_IN_Pin|PCA_INT_Pin|P_L_IN_Pin; GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING; GPIO_InitStruct.Pull = GPIO_NOPULL; HAL_GPIO_Init(GPIOJ, &...

In STM32F103xx manual, FSMC timing is seem wrong

In STM32F103xx manual, Synchronous non-multiplexed PSRAM write timings gragh (76page, Figure 31) is wrong?? This is same Synchronous multiplexed PSRAM read timings(Figure 28).Please let me know if the manual is wrong or if I'm wrong

Hi everyone, I'm working with HAL CAN driver, but sometime I miss trame ... I mean, I send a message each 100 ms with counter and sometimes I miss one value ... On STM32L4, does someones already have this issue ? First time I see that ...
