Posted on December 19, 2016 at 02:47Hello,I have an issue using the UART RX with DMA on my stm32f030k6t6...The microcontroller reacts exactly like the DMA was not correctly initialized.I'm using USART1 at PA10 (RX), and DMA1 channel 3. Here is the c...
Posted on December 02, 2016 at 04:43Hello, I am designing a project using STM32F446, hoping to get more performance than STM32F401/411.After some research and trial and error, it looks like this MCU does not support full duplex I2S. I could not find...
Posted on December 12, 2016 at 17:03HiYou recommand to switch on the board X-NUCLEO-IDB05A1 but i have the X-NUCEO-IDB04A1.You can see on my previous posts, i'm working for a package for the stm32f746g-disco.I'll be in holliday at the end of the wee...
Posted on December 17, 2016 at 11:18Hello,i am working on a school project regarding 3 phase motor control. I have a nucleo32 board with a stm32f410 deviceThe ideea is to generate a lookup table for the dutycycle values, and transfer them to the CCR...
Posted on January 21, 2014 at 10:36I'm having some troubles connecting an ST-Link to a STM32f0 microcontroller. Did is what i did/tried: Soldering STM32f051 (LQFP48) to DIP adaptorVBAT, VDDA, 2x VDD to +3,6VVSSA, 2x VSS to GNDBOOT0 to GNDNRST with...
Posted on December 29, 2015 at 03:33I am using the STM32F072RBT6 64pin LQFP My code seems quite stable, but this chip is showing signs of being overly sensitive to temperature... Since I have so much capacitance around the board on the same power l...
Posted on December 17, 2016 at 19:28Hi,I would like to know if I can use one I2C bus for 3 devices, first is master, sencond is slave and third is master/slave (STM will siwtch between master and slave mode to communicate with this 2 devices). Is th...
Posted on December 16, 2016 at 14:08Hi,My name is amarr., am new to this forum, I am trying to send some AT commands to STM32F401VDT controller throughSPI protocol to Wifi module(ESP12E vendor Ai-Thinker). For that purpose i need to make Module into...
Posted on December 15, 2016 at 14:11Hello, I'm trying to work with USB FS mode embedded in stm32f407vgt6 as device connected to PC(host), the reference manual says FS mode supports 12MHz speed and it's mentioned in the notes of CDC library (version ...
Posted on December 15, 2016 at 22:59I have a STM32L152 device which spends most of its time in STOP mode, waking perhaps once an hour. I'd like to add IWDG support, but need to 'freeze' the IWDG during STOP mode, which per STM docs can be done.I hav...
