Posted on October 24, 2013 at 13:38Hello,I'm using the STM32F373 microcontroller and wrote a simple function to read data from a MPU6050 gyro/accel on bus i2c.Problem is that when i try to read data - flag I2C_ISR_TXIS always equal RESET (not set).W...
Posted on October 24, 2013 at 10:19HelloI've discovered something quite interesting and annoying at the same time, let me share this in case someone stumbles upon a same issue.I use SPI1 in STM32F103RC and STM32F4Discovery to communicate with ADIS16...
Posted on October 12, 2013 at 18:16I am using two STM32F407x boards.board 1 sends a data packet continuouslyboard 2 parses data continuouslyIn order to see if the data is being parsed correctly, I am adding break points in the code. The problem is t...
Posted on October 23, 2013 at 20:39Chip : STM32F429/439.I tried to set BFB2 from ST-Link Utility. From the user manual, it should have a check item under Target/Option Bytes.I downloaded both v3.0 and V3.1. both missing the BFB2 check box. Is there ...
Posted on October 23, 2013 at 12:53Hello,I initialised on USART3 a communication port for TX and RX. This is working fine : I can send messages and receive messages from another device (at the same UART speed of course).But try to link the USART3 TX...
