Posted on June 13, 2016 at 14:36Hello,As i am designing a project for low power application. The best microcontroller that i had selected is STM32L053R8 which is cortex m0+. Now after drawing shematics according to my application requirement i found...
Posted on June 13, 2016 at 13:53No peripheral enabled.Only mcu is mounted and power is feed from power supply directly.Current is nearly 170 uA at MSI 1Mhz low power sleep mode.but cubeMx says 65 uA.In other modes, current is almost 100 uA more than...
Posted on November 11, 2015 at 06:04hi all, I am a newbie in STM32. Now I get an application to make STM32L476 as an USB audio device and playing music in PC will play in the speaker connected to STM32L476. I use the USB audio class(device) and win...
Posted on June 02, 2016 at 15:24Hi All,The device is being used STM32F746BGTX.Set as follows. FMC_NORSRAM_TimingTypeDef Timing; /** Perform the SRAM1 memory initialization sequence */ hsram1.Instance = FMC_NORSRAM_DEVICE; hsram1.Extended = FMC_...
Posted on May 31, 2016 at 16:28I am working with the Discovery Development Board and a custom-made PCB with an STM32F405 microcontroller operating at 1.85 Volts. I would like to be able to easily switch clock frequency, that is, I would like to have...
Posted on June 13, 2016 at 09:37Hi,I need help enabling page read mode in external memory http://www.issi.com/WW/pdf/66-67WVE4M16EALL-BLL-CLL.pdf.This external memory supports faster asynchronous page reads (shown on page 10) but Ican not find need...
Posted on June 13, 2016 at 02:06 Very new to STM32 development and am not an engineer, so apologies for what is likely a very silly question. I'm attempting to use an STM32F103 as a programmable replacement for a game cartridge ROM. When ...

Posted on June 09, 2016 at 20:36 Hi all, I'm trying to setup a very simple Memory to Memory DMA transfer. DMA status registers report that the transfer completes OK, but the memory contents is not transferred. Can anyone see why...
Posted on June 12, 2016 at 08:51Hi!Im trying to use two EXTI on PE2 and PE3 pins simultaneously. Two push bottons are connected to these two pins with a pull-up resistor and a capacitor filter prohibitting debounce phenomenon. As shown in the code b...
