Posted on January 14, 2018 at 10:34Hi everyone,Should I connect a any series resistor to the super capacitor while using a super capacitor that is 1F 5.5V instead of a battery? Or I can connect directly the capacitor to VBat pin?#power-backup-superc...
Posted on February 16, 2018 at 06:26I've been developing code for a project using the STM32CubeMX initialization code for the Nucleo-L476RG. I was previously using an older version for code generation, and recently upgraded to version 1.11.0 of the ...
Posted on February 14, 2018 at 22:26Hello everybody I am working on a design using STM8S103F2P6TR and will produce a big quantity of it so I am thinking to make another portable design using STM32F407VGT6 as a flasher to program the units after manu...
Posted on March 12, 2017 at 17:12Hi. I have an STM32F746 Discovery board purchased late last year from Digi-Key. It uses a STM32F746NG chip. I have not found any documentation anywhere that defines which revision of the Cortex M-7 core it uses. I am...
Posted on October 06, 2017 at 21:42I know the counter register read is not very reliable:Bits 15:0 CNT: Counter valueWhen the LPTIM is running with an asynchronous clock, reading the LPTIM_CNT register mayreturn unreliable values. So in this case it...
Posted on February 15, 2018 at 20:15Can anyone help to explain the method to calculate the I2C timing register?I am trying to come up with a value for 400KHz. I2C1 clock is from HSI16 which also has the /div4 enabled.I am very confused by the set up...
Posted on February 15, 2018 at 20:04Hi! Working with the STM32F746ZG RTC. Clock, Calendar, and wakeup interrupt working fine. Have Battery Backup for RTC. I'm trying to perform a Smooth Calibration which does work but I find that not all of the CALM...
Posted on February 14, 2018 at 13:35Hi,I am currently using the STM32F769I-EVAL MB1219 Rev B board. I wanted to boot the MCU in the DFU bootloader mode, and as the manual suggests I removed the 0 Ohm resistor R124. I also set SW1 to `1`.This looks l...
Posted on February 15, 2018 at 15:44I just purchased the STM32F769I discovery board. I am trying to connect my windows 10 machine to the board using the ST_LINK usb connecter on the board, but the USB port does not show up in the device manager. I h...
Posted on February 15, 2018 at 09:32Hi All,in my application, i need sometimes to stop PWM and Force Output to High.I write this code but seem not run good. void forcePwmActive(void){ TIM_OC_InitTypeDef configOC; HAL_TIM_PWM_Stop(&htim21, TIM_C...
