Posted on April 03, 2018 at 12:27Hi,I have Nuckeo-L452RE with STM32L452RE uC on board.This uC max speed is 80MHz.But after enabling MCO on pin PA8 in STM32CubeMX and generating the code to Atollic, I could see wrong SYSCLK frequencies.The reason of ...
Posted on March 04, 2017 at 16:13Ok so I am talking about the IRQ handlers for ADC, SPI, I2C USART etc.. I am expecting to see weak definitions of ADC_IRQHandler() function for example somewhere...but my startup_stm32.s file in startup directory doe...
Posted on April 04, 2018 at 16:58Where can I find the source of the demo software which is already loaded on a 'fresh from the box' NUCLEO-F767ZI please. I searched the forum and looked on the ST nucleo web pages already.Thanks - John F.
Posted on April 04, 2018 at 22:31I'm using STM32F207ZG ,What is maximum Voltage level at Tx and Rx pin in USART3? Can I use 5V CP2102 USB to TTL converter with STM32F207ZG?
Posted on April 05, 2018 at 04:13I'm using an STM32F302 (Nucleo-64). I have found code examples that set the rate to 1M. Where is the information on the timing calculations required?
Posted on April 05, 2018 at 04:11I am working with stm32 PMSM foc sdk 5.0. I want to drive the system by the application board and it can send a command to the motor drive board and get a feedback.The application board and motor drive board communic...
Posted on April 05, 2018 at 03:50Hi.I am going to set the RDP-Level 1 programmatically.Here is the test code:Here it stops at the HAL_FLASH_OB_Launch () function.The Reset button does not work in this state.The USB connection will work only if you r...
Posted on April 05, 2018 at 02:00What is the ADc input impedance on the STM32F303VCT6? How to decide of ADC input sampling time? My signal is very low frequency (10 kHz).Please let me know.Channamallesh
Posted on April 02, 2018 at 23:30Hi everyone,I'm working on a board based on STM32F4XX. We plan to support USB Host on it for communication(CDC). I found there are 'USB On-The-Go Host' and 'USB Host' libraries. I'm not sure which one to use.First, I...
Posted on April 04, 2018 at 17:30HelloI have a STM32L4 MCU in my coming product. I'm running a master timer at 500Hz. The master timer triggers four other timers. All of these timers drive PWM at 500Hz at different phase. (Cannot be done using singl...
