Posted on January 05, 2017 at 15:52I am currently working on a project that uses Etherne with CubeMX and lwIP.During the development, I found rather difficult to manage the cases when the physical link becomes invalid (e.g. cable unplugged), or it i...
Posted on February 10, 2017 at 21:40Hi, I would like to use a 320x240 TFT RGB interface display using the STM32F767ZI internal SRAM. But I can't figure out what is the minimum SRAM required for the frame buffer. For 16 bits RGB565 would be 320x240x2...

Posted on February 10, 2017 at 04:34I am using the STM32 ADC to caputure outer voltage , while the requirement to ADC accuracy is not very high. So I decided to use the VDDA as the reference voltage. BUT the actually vdd added to the mcu exist dev...
Posted on February 09, 2017 at 14:42has anyone tried to play a video file using the new STM32F77x JPEG codec ?I use an external Video drive processor, so there is 100% of internal processing power available.I see this in the attached PDF,' As the J...

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...
