Posted on February 17, 2016 at 16:44I built my own board and I am trying to use the JTAG connections. It does not seem to work. It only uploads a small percentage of time and even when it does, I am not to sure it is uploading correctly. I thought ...
Posted on February 16, 2016 at 08:16Hello there, I have a general question regarding the NJTRST signal in a JTAG protocol. In STM32 datasheets, I read that JTAG can operate with only 4 pins, without NJTRST. I only assume it then uses regular #RESET ...
Posted on February 17, 2016 at 11:48Hi, I'm second year student at UTP in Poland. I have to do project based on STM32F407VG. It's just simply communication with keyboard. But I have problem - power on my keyboard. I read that to power PS/2 I have t...

Posted on February 17, 2016 at 18:38Hi, I am new to the STM32 family and I am stuck with a pretty basic problem. My board (STM32F105 CAN study board) came with a basic software in Flash, and I got the sources of that software which I am running from...
Posted on February 17, 2016 at 15:48Is there a STM MCU with RS-485 integrated on it ? It would be very usefull given the fact that MCUs are industriall devices and one of the most used communication protocol in industry is RS-485.
Posted on February 17, 2016 at 07:48Hello,We have an requirement for field program-ability using USB interface. Our SW development team already using ''STM32F4 DISCOVERY KIT'' for their development activities. Controller is STM32F407VGT6.The discove...
Posted on February 17, 2016 at 17:48Specifically, what registers do I look at and what bits? Also, does the peripheral library wrap all the code needed to handle error frames? #stm32 #canbus #can
Posted on February 16, 2016 at 17:44Hello,I have try to send data from my stm to accelerator.The problem is when I check the flag before start to sending first command it stuck on busy.(I2C_GetFlagStatus) my pins are :D6, D7 (PINS that are free)What...
