Posted on February 10, 2017 at 09:43hello dear forum,I want drive 7 segment common cathode LED display with STM32F103if I turn on all the segments 10 x 8 = 80 mA totalcan the STM32F103 supply this much current in total?thank you
Posted on February 10, 2017 at 01:35Does anyone know how to enable the TSC interrupt on a L053R8? I'm working on a project that when you touch the captive touch and LED turns on but I can't find how to enable the interrupt.
Posted on January 24, 2017 at 19:28HelloIt is mentioned in the table 87 (DCMI characteristics, stm32f405/407 datasheet, Rev7) that max DCMI_PIXCLK is 54 MHz, and it's mentioned in the RM0090 that this peripheral is capable of up to 54MBytes/s transf...
Posted on September 18, 2015 at 03:49Hi All, I am having an interesting I2C problem. A slave device i am reading from has a variable length response, the length of data is read from the device so i do not know how much i need to read until i start t...
Posted on February 06, 2017 at 14:22 I had problem for 'HAL_UART_Transmit_DMA', once I transmitted some data, I couldn't send any data after that. I used this function, 'HAL_UART_Transmit_DMA' in 'USART1_IRQHander'. (Because I should pars...
Posted on February 07, 2017 at 20:27Hi all,I have configured ADC to work in DMA mode for 4 channels. Code was generated via Cube. After I call function HAL_ADC_Start_DMA everything works fine until I trying to call other HAL function. In this case, ...
Posted on January 11, 2017 at 11:32Hi,I'm working with a stm32f437VI. I need more heap memory. I changed the Heap size in de startup_stm32f427x.s (Heap_Size EQU 0x00000200), but when I did a malloc and worked with the variable, and excepti...
