I had build a host-client system , both host node and client node based on STM32F103C8T6. If host does not received client‘s [I'm alive] message though CAN bus for a while (about 2 seconds) , host power off client by turn off a P-Channel MOSFET, ...
I am using a STM32072B-EVAL board because I need a working demo about HDMI-CEC.It is clear that there are problems: the original firmware already on the board has errors about icons (some graphics is broken), about images (it hangs if try to show an ...
Registers "TIM3_CCR1" "TIM3_CCR2" that should hold the frequency and the duty cycle of the signal always equal zero
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...
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...
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, ...
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...
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 ...
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...
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 ...
