Posted on October 01, 2016 at 19:46 Hi, I am using Nucleo F103 and Keil compiler. I m facing some problem while receiving data. In debug i could see data is receiving in DR register. But data is not getting transfer in other register. Eve...
Posted on October 06, 2016 at 06:30is there any way so that i can know whether my uart is active or not ,i wanna send an AT Command to a gsm module such as ''AT+CCLK?'' in return of this command the GSM module will give the time and date from neares...

Posted on October 05, 2016 at 19:34I'm using SPI to get data from and ADC: I need fast acquisition so I'm using a STM32F4 board at 50MHz. Using a Logic software I noticed that the spi clock doesn't work at high frequency (50MHz), while it works at l...
Posted on October 05, 2016 at 17:32I studied the connection diagrams or pin out reports of my Cube project. I want to be extra careful because this is my first STM32 project. I noticed that there could be more information about power supply pins. It...
Posted on October 05, 2016 at 16:16 Hi. I would like to implement some kind of fault handling mechanism, which would store some CPU registers, PC, etc. in flash if error occurs. I tried to store SP value within HardFault Handler like this:...
Posted on October 12, 2015 at 16:33 Hello I'm trying to send a 16 bit number with the SPI peripheral on a STM32F030 with the new HAL libary. Sending an 8 bit value is very easy but with a 16 bit number I receive errors or the hardware is ...
Posted on February 09, 2014 at 15:09I am starting this post to hopefully determine the proper initialization procedure for the I2C peripheral. I am specifically using an STM32F407, but I am assuming that this will be helping in a broader sense.The b...
