Posted on July 08, 2017 at 22:35On page 34 of the STM32F030 datasheet there is a table of Alternate Functions that I think contains an error.If you look at the GPIOA_AFR registers for port A and select column AF4 you will see that TIM14_CH1 is menti...
Posted on June 08, 2017 at 18:14 Plese . I have some problems with RTC Calendar. I do not understand how to use it. You can send me some examples for STM32f407VGTx Discovery. (HAL Library)With HAL_RTC_SetTime (& hrtc, & sTime,...
Posted on July 04, 2017 at 22:53Working off the provided example for PWM on STM32F100RB I am able to output varying levels of PWM, however, my attempts to change the duty cycle of a specific channel according to user input have failed. I do not see ...
Posted on July 08, 2017 at 23:04Attempts to capture external PWM signal with TIM.h library have been unsuccessful. I figured using semihosting to print values to console would be helpful in debugging however the values refuse to change although I kn...
Posted on July 08, 2017 at 00:39I continue to look for answers to difficult questions.There is a project for an arm under GCC with a static load. Addresses of variables and data do not change, for gcc everything is known, and it successfully optimiz...
Posted on July 07, 2017 at 19:40Hi everyone,I'm trying to receive a msg via CAN-bus in interrupt mode with STM32F105 mcu. I set the CAN filter so that only 0x0106 and 0x010A IDs are allowed. This is the first time I use this microcontroller so I'm n...
Posted on July 04, 2017 at 05:25I understand that CPOL takes effect only after SPE is set. But when I talks with AD7606, I need to have CPOL high at idle, and one line only(either BIDIMODE=0 or BIDIMODE=1) for receiving. In this mode, SPE can only b...
Posted on July 07, 2017 at 20:42Hello, I interfaced STM3210E-EVAL with external RF Slave chip and trying to place a data in a slave register.Ex data: Slave register address is 0xC0 and placing two bytes of data (0x00 and 0x12). For this I configure...
Posted on March 15, 2017 at 07:30hi,I want use LPTIM1 and select clock source is LSE.when i enable LSE use code auto-gen from stm32cubemx,but LSERDY can't assert,the external OSC is work normal.init code like as:void SystemClock_Config(void){ RCC_O...
