I have a problem with Input-Capture driver for Timer3 specially for stm32f10x
Registers "TIM3_CCR1" "TIM3_CCR2" that should hold the frequency and the duty cycle of the signal always equal zero

Resolved! PA0 and NUCLEO-H743ZI
Hello,I want to use TIM3 as 32-Bit counter. Clock source is set to ETR2. The corresponding Pin is PA0. For test purpose I use TIM3 to generate a clock signal (Pin PC6) to feed the TIM3 counter.Connecting these to pins together (PA0 and PC6) results i...
Connecting STM32L4 over I2S (SAI port) to external Audio Codec
I have an analog mic connected at an Audio Codec (MAX98090) which provides an I2S connectivity.I would like to connect this Codec over I2S to the STM32L4 . I have SensorTile and the Nucleo, both have the STM2L476 chip with 2 SAI ports to test the con...
HAL_UART_Receive not working after a while!
Dear friends,there are two threads in my application , one is used for TCP/IP using lwIP and the other one is for RS485 protocol. Everything works fine correctly and I can send and receive data on RS485. After two or three hours or sometimes sooner, ...
Resolved! Where does the output of 'sprintf' goes to ?
Hello,I use stm32cubeH7 examples.I find in some of them call to sprintf, yet I don't understand where is the output of the sprintf goes to:I tried opening the "STMicroelectronics STLink virtual com port" - nothing is printed hereI also tried to searc...
CAN Setup with STM32-Mat/Target in Simulink ?
Hello,I'm trying to use the STM32 MAT/TARGET to setup a Communication between Simulink and a STM32f107vct via CAN.When I want to build the Simulink model i get an "INVALID INDEX" Block Diagram error.I am using Matlab R2018b and the latest version of ...
STM32F103 UART Tx interrupt
Posted on February 07, 2015 at 13:30Hell all, I have two UARTS connected to two devices (say A and B). Both UARTs Tx and Rx is interrupt based. When I receive a message from A (ASCII-Z string) and the same message is sent to B, I am getting the mess...
Could not read the Interrupt Priority after vTaskStartScheduler()
Hi All,I want to use NVIC_GetPriority(DMA1_Channel4_IRQn) function with FreeRtos. I can use this function before the vTaskStartScheduler(); but, when I call NVIC_GetPriority(DMA1_Channel4_IRQn) function after vTaskStartScheduler();, it does not work ...
Sending UART data at maximum speed without interrupts
Hi,There something odd with the USART3 (the Virtual COM one). I can send characters, but there's some speed limit that I can't surpass.I'm trying to loop a string as fast as possible, but I can't get the optimum speed, I'm having to use a delay (or a...
Resolved! NVIC_Init() library function does not work as expected
Hi All, I have simple code to assign preemption priority and subpriority. I have tested this code on the stm32f103. Even if i set the preemption priority and subpriority, when I read the priority it returns as 0x00. According to the information from ...
