Posted on August 14, 2017 at 16:32Hello, I am using STM32Cube lib to development my project which include both spi and i2c communication.So I develop the project based on the SPI example in STM32Cube example package.However the initial project do no...
Posted on August 15, 2017 at 10:03I am working with the stm32f4 Discovery Development Board and put simply, there's a while loop (with some conditions) in my main() function. Is it possible for the code inside the while-loop to find out it has been ...
Posted on August 15, 2017 at 11:09Hello,I have a question to the note in the datasheet (RM0385 Rev 6, Page 682). Bit 3 OC1PE - Note 2.What means this note?'The PWM mode can be used without validating the preload register only in onepulse mode (OPM b...
Posted on August 15, 2017 at 12:27HiI have a USB barcode reader that acts as HID keyboard. When I plug it in to a Windows 10 machine it identified as 'USB keyboard device' (under device Manager - keyboards) and works fine: if I open text file and sc...
Posted on August 15, 2017 at 12:19Hi all, I am using STM32F407 to develop a control unit for EV charge. I have a difficult to init the MCP2515(SPI to CAN). So is there any mcp2515 library for stm32f407ThanksAndy

Posted on February 17, 2017 at 07:53Hello, Entering SW-DP mode can be done by following instructions in RM0351 chapter 44.3.1. External TCK/TMS sequence is required.Is there any other way to change from JTAG-DP to SW-DP? With ARM Cortex-M3 this can ...
Posted on August 15, 2017 at 02:33I'm using CubeMx with the STM32F415.Looking at the HAL drivers for I2C slave devices using DMA, it appears as if the HAL_I2C_Slave_Receive_DMA() and HAL_I2C_Slave_Transmit_DMA() functions will effectively be blockin...
Posted on August 14, 2017 at 11:47Hi,I am starting out with STM32 (STM32F103CB). I am thinking of using Visual Studio with VisualGDB and Seggar debugger. Are there high level libraries I can use for setting up IO functions and also for delays and no...
Posted on August 14, 2017 at 06:13 Hello, I am trying to get a basic project working using the CMSIS register definitions. Below is the code I am flashing to my NUCLEO-L432KC. LD3 does not light. My understanding of the demonstration board's p...
