Posted on June 19, 2013 at 20:08hello i have a folder contains many projects and all of them goes to same library file , each projects work great , but when i copy the main code of one project to other i got the linking problem like that ''Error[Li0...
Posted on June 23, 2013 at 23:15in datasheet the maximum speed of gpio is 84mhz it means ( 168mbit ) because 1hz=2bit
Posted on February 23, 2013 at 15:36 hello forum , please have a look at my STM32F4 code - the USART1 interrupt never gets called when a character arrives at the serial port I am sure about my PC side program becouse it is tested...
Posted on June 20, 2013 at 22:30Hi, I'm desperate to not achieve my project with the internal temperature sensor of STM32F0 For now I try to read the sensor factory calibration data stored in the system memory by simple pointer that way. (53) uint...
Posted on June 22, 2013 at 19:06 Hi everyone, I'm trying to configure I2C3 on the stm32f4 discovery board but i end up in the hard fault handler at I2C_Init. I am doing something weird i'm sure, any ideas? void I2C_Co...
Posted on June 23, 2013 at 14:16When I use the function ''GPIO_PinAFConfig'' in order to map pins to the device can I use any pins I want or I have to respect some roles ?
Posted on June 21, 2013 at 09:36Hello everyone, I'm working on STM32F4discovery board. I used the example in the firmware and it worked. But when i wanted to upgrade firmware with my own codes, it didn't work. I even used the codes in the board firm...
Posted on June 20, 2013 at 13:24I am using PB0 - ADC2-IN8, as analog input with 10K source impdence. I have configured the pin and sampled continuosly. Values shown shows gradual decrease if delay not added b/w two samples. I am using software contr...
Posted on June 20, 2013 at 06:05I have an STM L3GD20 gyro which I am interfacing with an STM32F0. The gyro has two interrupt pins, and INT2 is specifically labeled ''DRDY.'' I'm under the impression that it can produce a pulse after each sample is c...
Posted on April 02, 2013 at 17:16I found it is not correct on STM32L152-EVAL USART baud rate. The clock configuration is set as below. I use printf to show some character such as ''hello world'' on the terminal. It only works with 9600. And the baud...
