Posted on July 03, 2015 at 12:48 I have a number of devices connected, some sample the data on the rising clock edge, others on the falling edge. Inside the handler structure I want to alternate between these two operation modes. A method...
Posted on July 02, 2015 at 18:38Hi,For STM32L4.I would like to know if SPI2 and SPI3 maximum clocks are also 40MHZ or only SPI1 clock is?Ari.
Posted on July 02, 2015 at 20:50 Hi, I currently have an issue with TIM1 being reset unintentionally by the relationship between TIM2 and TIM5. My system has TIM2 encoder counting and generating a TRGO during compare pulses. TIM5 is set i...
Posted on June 23, 2015 at 11:07Hello, I do not understand why the TIMER instance is stopped when a specific bloc is stopped. For example, I have 2 output compare channels activated on TIM2 with interruptions. If I use HAL_TIM_OC_Stop_IT in order t...
Posted on May 30, 2015 at 02:53This is is very simple project, using stm32f4 discovery and wired microsd socket to read/write data to microsd card.the code is generated by the stm32f4cubemx.However error occurs at f_open, tracking down it shows FS_D...
Posted on June 28, 2015 at 19:28Hello, i started working with some texas instruments rf modules, namely cc1120 and cc1190 wireless ic's. My idea is to build a rc remote control based on a ppm input signal. I want this signal to be procesed via my M...
Posted on June 30, 2015 at 06:06I wrote Option Byte and Enalbled Write Protection all flash page.I can't program MCU. It say flash is protected.How can I fix this problem ?Thank You.Khoa Tran.
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 (...
