Posted on February 22, 2014 at 15:16hi guys,it's my first visit in the group, can you help me ,i have recently bought stm32f4discovery board and learning arm controllers ,before i used avr risc 8bit controllers and have more skills in it ,but to do ...
Posted on February 21, 2014 at 22:37Hi,I'working with USB to send data from my F3 Discovery to the PC. For that i used the CDC class. I managed to send few bytes of data using the routine below:uint8_t TabInt[6]={80,90,88,99,10,13}; uint8_t *ptr_i...
Posted on January 28, 2014 at 10:50Hi! I have been playing with a STM32f103rbt6 chinese board for the last few months, it's working well. I am using the SWD of my stm32F4 discovery to upload the program. Now i wanted to make my own board, so i desig...
Posted on March 04, 2014 at 12:10Hi,I have the SPI communication working but do not receive the answer of the slave. I can see the answer on the scope but not in the controller. Can anybody help ?My main.c/* Includes --------------------------------...
Posted on March 02, 2014 at 19:38Hi. I'm currently in a group who are building an ROV and using the stm32f100rb to controll 7 rc motors. The issue I'm having is when outputting a pwm signal to a osciloscop I get a very rough resolution. The signal i...
Posted on March 04, 2014 at 00:42Hi all,I am playing with SPI examples of STM32L recently and would like to ask a simple question about the SPI clock rate. When I read through the datasheet, it mentions APB1 and APB2 have maximal frequency of 32MHz...
Posted on July 30, 2013 at 10:08I have managed to make Flash loader demonstrator work with my FTDI. Whenever I want to connect to my STM32F4 Discovery board I have to do that in two steps. Firstly I connect proper pins from FTDI to PCB, then I open ...
