Posted on July 01, 2015 at 12:44Hello everybody, I am developing an application with external interrupts on a falling edge of Pin PB3 on an STM32l151VB. With reuse of code I initialize the EXTI line twice using the function ''SYSCFG_EXTILineConfig''...
Posted on July 02, 2015 at 09:57 Hi： i use the DMA interrupt to send 8 byte data and receive 9 byte，it can only executes once，but when i debug it step by step，it works well。i'm so confused.Sorry for my poor english. Here is my code，is ...
Posted on June 26, 2015 at 14:40STM32 documentation says that the I-CODE and D-CODE buses are connected to the internal flash memory. The I-CODE bus is used to fetch instructions and the D-CODE bus is used for data access in the code memory region (...
Posted on June 29, 2015 at 17:12Hello everyone,I'm using the MCU STM32F072CBT6TR and now I need to make a coverage analysis for this microcontroller but I really don't know where I should start.Do you have some suggestions?Tools, SW etc etc... whate...
Posted on June 30, 2015 at 12:10Hi,I used STM32CubeMX to configure Timers 10 and 11 in interrupt mode (Along with FreeRTOS)void HAL_TIM_Base_MspInit(TIM_HandleTypeDef* htim_base){ if(htim_base->Instance==TIM11) { /* USER CODE BEGIN TIM11_MspInit ...
Posted on June 30, 2015 at 17:03I am using the DAC outputs on PA4 and PA5 of the STM32F427 LQFP 100 pin part. On power down, these pins show a voltage spike in the range of 1-3V and 50-100mS in length. It didn't seem to matter how the pins were conf...
Posted on July 27, 2014 at 05:18I have been trying to get the OV7670 cam working with STM32F207zg but seems like something is not clear , first i need to know what is the buffer size to set the DMA to when i want to transfer a snapshot from the cam ...
Posted on July 01, 2015 at 01:23I have been using a STM32373C-EVAL board and programming it via the onboard STLink. Recently we've moved towards our own hardware design and so to verify that our SWD programmer was working I was testing programming t...
