Posted on October 26, 2015 at 07:07Hi everybodyI am using STM32 PMSM FOC LIBv4.2 to turn a three phase 60V/350W BLDC motor with Pole pair=28 and rated speed=265rpm. I am using Hall sensor to detect rotor position/speed and Single Shunt current measu...
Posted on October 16, 2015 at 05:23Hello.I have to use asynchronous and synchronous modes. For asynchronous, I'm already using the built-in USART peripheral. My problem is the synchronous one. My clock needs to be 16 ticks per bit and more important...
Posted on October 21, 2015 at 20:31Hello,I using STM periph. library and I would need to use two UARTs on STM32F103. One UART for serial Modbus RTU comunication with sensors and one UART for terminal interface which will show data from sensors and p...
Posted on October 23, 2015 at 14:43Hi, is there any difference how exactly I'm getting the desired clock speed on SYSCLK through PLL? For example, let's say I want to have 48MHz on SYSCLK on STM32F407, using a 8 MHz HSE and the PLL. One way of doing...
Posted on October 23, 2015 at 23:11Hello,I have set up a project in CubeMX (lastest version) and is working fine.The only very annoying problem is that the user interface is very very slow, especially the pinout tab. If i click to show the dropdown ...
Posted on October 16, 2012 at 17:00I would use the printf function to transmit strings of hyperterminal, but if I use the printf function, the microcontroller stops! I am developing my code on STM32F4 Discovery
Posted on October 24, 2015 at 16:36Hi, i just wanna ask how to convert BMP images to hex rgba arrays as 0xF75AFFDE,0xFF78F738, 0xFFFFFFDD, 0xEF12FFBC, 0xEF59EF12, 0x8C69B570....etcThere is an example of LTCD about how to display one layer and it sho...

Posted on October 24, 2015 at 16:08I am building HID keyboard by STM32F072C8T6, can I just build without external 8M&32.768K oscillators to save the layout space? any technical risk?I don't know if the Clock Recovery System (CRS) circuitry, which co...
Posted on October 20, 2015 at 05:13Hi, I am new to this forum, new to ST world. Where I should start to look into programming 1 wire GPIO, generating bursts with custom widths 100 .. 300 micro-seconds for STBC02 chip. For example to turn one of th...
