Resolved! How to make N pulses with One pulse mode, but pulse first delay after.
Hello i am trying to make N pulse in some exact time, when i adjust a timer with one pulse mode,everything is ok but pulse always start with a delay because it is basically a pwm single starting with low side and high side. I want my pulse start imme...
is there any example for aci_gatt_update_char_value_ext()
I want to send 2052 byte data through BLE but eventhough I read PM0271 and AN5270, i cannot exactly understand it.Could you suggest any example for this?
Resolved! I2C DMA not triggering callback function
Hi,Could you please suggest a direction with my problem?I try to read and write data to a sensor via i2c with DMA1 in an STM32 Nucleo F401 board where a FreeRTOS is running.I can read the sensorata with polling methode, and next to the I2C an UART is...
How to round division on STM32G0
I'm trying to implement an integer division with rounding. Obviously, by default integer division does floor and I was thinking I could use the remainder to determine if I should add 1 to my result.Processor cycles are at a premium in this solution (...
I need help selecting the microcontroller for the next project.
Based on operational requirements I narrowed down the selection to the STM32F413. The murky part is the field firmware update (customer side) capability. Is the STM32F413 capable of encrypted, customer side, firmware updates? I watched the Security r...
STM32L412: State of pin PB9 doesnt change, no matter the configuration
Hello,Thank you in advance for any answers and your time.I am using STM32L412CBT6P for my application. There are 2 custom boards with the same part and the following problem exists in both of the boards. Also attached is the connections diagram to th...
Resolved! WARNING: CPU random generator seem to be failing, disable hardware random number generation WARNING: RDRND generated: 0xffffffff 0xffffffff 0xffffffffff 0xffffffffffffff
Hello community,since I updated the STM32 Cube IDE the following problem is displayed when entering the run or debug session.WARNING: CPU random generator seem to be failing, disable hardware random number generationWARNING: RDRND generated: 0xffffff...
I want to develop a C program on the STM32F303 board that uses the SPI interface where the microcontroller is the master and the L3GD20 gyroscope is the slave: I want to perform a transmission to ask the gyroscope to provide me with the x, y, z coordinate
Considering that the gyroscope's chip select is the PE3 pin, how should I do this? The program below doesn't work#include <stm32f30x.h>void GPIO_Config();void SPI_Config();uint8_t L3GD20_Read(uint8_t reg);void L3GD20_Write(uint8_t reg, uint8_t data);...
