Posted on January 29, 2017 at 15:52Hi, I'm new to STM32 microcontrollers, now I have STM32F3Discovery board and I want to implement a signal follower.The microcontroller read the signal from ADC1 pin A0 and generate it on DAC1 channel2.when I have c...
Posted on January 06, 2017 at 22:16Our application uses the SMT32L4 in a 4-20mA loop-powered transmitter. VCC on this device is 3V. The typical current draw once the product is operational is approximately 8mA @ 3v. We are utilizing the bootloader t...
Posted on April 18, 2015 at 23:00Hi,I am not able to program the flash of a STM32L151RC using ''half page'' programming.Normal programming (word by word) works fine.I have tried it using the 2 latest GCC compilers (4.8.4), and I have tried with the ...
Posted on January 26, 2017 at 17:04UART_Printf example (Nucle-F767ZI, 144 pins) works correctly, I get printf output on OS X, using Zterm (PC HyperTerminal replacement).However mouse is locked when I connect with Zterm and start listening. Computer ...
Posted on January 24, 2017 at 11:07Hi,How to use UART in DMA mode with interrupts IT.I use the next code to transmit, and it works perfect. HAL_DMA_Start_IT(&hdma_usart3_tx, (uint32_t)msg, (uint32_t)&huart3.Instance->TDR, strlen(msg)); huart3.Instan...
Posted on January 24, 2017 at 12:53Hello,I want to make a bridge from USB to Ethernet, to give connectivity to a tablet.I am using an STM32F107RC, a DP83848CVV phyter and the CubeMX to generate the code with this configuration:I do not know how to l...
Posted on January 25, 2017 at 19:16I am interfacing to an LIS2MDL Mag using 1-wire SPI bus mode. The MCU is an STM32L4 and I am using ST's HAL peripheral library 1.5.2.Reading from the Mag seems to be a problem. I connected a scope to the CS, data...
Posted on January 24, 2017 at 10:50 Hi. I'm trying to communicate with I2C peripheral using SDK package mentioned in title. I'm using HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive functions to read and write to bus. However both report er...
Posted on January 17, 2017 at 10:20Hello All,I am interface a SD card with STM32f4 discovery board. i am use the SPI protocol for the same.I use the IAR IDE for the development.I need the example code for further development.So, please share the exa...
Posted on January 23, 2017 at 03:53I am using the FUSB2805 HS USB phy with the STM32469. The usb interface seems to be working alright. Sometimes the phy gets into a weird state after restarting the micro but not the phy. I would like to perform a s...
