Posted on May 10, 2011 at 16:50I'm trying to get flow control working on Uart1 on the discovery board and am seeing some odd behavior. I have a little test program that receives 10 characters, pauses, and then echos them back. At the host (linux)...
Posted on March 04, 2014 at 12:59Hi , I am about to draw the schematics of a card which has STM32F405RG on it. I want to program my card throug SWD port. I made the pin connections as I described below: NRST: pulled up to VDD with 100K SWDIO: pull...
Posted on March 04, 2014 at 17:51 Hello everybody! I try the new stm32cube examples, with CoIDE. I check the truestudio example, and make the CoIDE project same for this, but I have linker error and I dont know what is the problem. This ...
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...
