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 ...
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...
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 ...
This is my usart handler Also I clear the 1st received frame before receiving the 2nd modbus frame.void HAL_UART_IRQHandler1(UART_HandleTypeDef *huart){ __HAL_UART_CLEAR_PEFLAG(huart); __HAL_UART_ENABLE_IT(huart, UART_IT_ERR); __HAL_UART_ENABLE_IT(hu...
Hello, I'm trying to set two different filtering modes with the DFSDM (on the same channel). each mode has different parameters. In my code, first, I Initialized the DFSDM unit with default parameters. Then, when a certain condition is met, I tried t...
I have this problem... I installed the : STM32 ST-LINK Utility, BUT STILL NOT WORKING. I have Windows 10, 64bit.
In my system (STM32L471) I want to periodically measure Vbat. Can I do this through the Vbat pin if Vdda may not always be present? Obviously I turn on Vdda whenever I want to measure Vbat but are there any leakage currents or other problems in case ...
Posted on May 24, 2018 at 14:21I already loaded some *.bin files, perfectly compiled with a perfectly functional tool chain.But today it doesn't work anymore...If I check with STLinkUpgrade 3.2.10, it tells me that the firmware is at version V2J30M2...
