Posted on June 17, 2014 at 10:53Hi folks,I have ST's Flash Loader Demo application for programming via a UART and was wondering if anyone knows if there's an equivalent for programming via USB. I want to use the DFU bootloader so I can program witho...
Posted on February 04, 2015 at 11:08Hai all, I am sending GPIO toggle application via ethernet to STM32F407.My application total length is 2920(.hex file).But in controller side i am getting 1460 data only.In controller i am receiving data like, ...
Posted on February 09, 2015 at 15:24Hello,I'm learing to use STM32Cube and HAL.Then I tried to set TIM encoder mode,but it can't work.This is my code of initialization and functionCan someone tell me ,what mistake I made or what important step I mis...
Posted on February 11, 2015 at 01:27HelloI have another work for transferring/receiving data using PLC(Power Line Communication)GPIOA port 12 is for PLC port.so I have looked for many of example and tutorial for 2days but there are no exist.....so i...
Posted on February 09, 2015 at 17:59Hello,I have to realize receive DMA timeout for a serial interface. I found the application note AN3109 which describes a mechanism to realize a DMA timeout for the STM32F10x microcontroller. Does this application...
Posted on February 09, 2015 at 15:51What is the usual procedure for power-on reset for other chips besides the MCU? Is there a reset_out signal or method coming from the MCU that is recommended? Or is there a method for resetting all chips in a syst...
Posted on June 03, 2014 at 09:43Hi,I am trying to debug some very simple code for STM32F0Discovery using Eclipse, ARM arm-none-eabi-gdb compiler and OpenOCD debuger.I could build and debug my cods and now I am trying to use printf to see some variab...
Posted on February 10, 2015 at 10:50Hi I am using STM32F103RBT6 @72MHZ I use SPI with DMA to stream data from memory to GPIO SPI Prescaler is 4 GPIO is configured as output push-pull and speed 50MHz The problem is that the data output rise and fal...
Posted on February 09, 2015 at 16:34 Hi at all,I would try to program a custom made board with STM32f205RCT7 micro onboard via SWD .I got an SWD connector with vdd,gnd,swdio,swclk,nrst.No pull up or pull down on swdio pin , 10k ohm pull up on nrst a...
Posted on February 09, 2015 at 15:06Hello to all, I use a TIM8 of a STM32F2xx to generate a quadrature signal. This works fine no problem with toggling mode. I send a sequence of pulses out of the OC-Outputs. (a speed ramp). When the sequence is ove...
