The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on January 24, 2018 at 09:11Hi, I am using NUCLEO-IHM03A1 eval boards on top of a Nucleo STM32F4IiREI to drive a NEMA23 stepper motor.The motors are stalling at relatively low speeds with no additional load. I don't seem to be getting the re...
Posted on January 24, 2018 at 09:44I'm using an STM32F401RET with code generated in the cube(v4.23) with F4 library(v1.18).The ADC is set up to sample one channel under a trigger from a timer with the values going to DMA. When 256 samples have been ...
Posted on January 23, 2018 at 19:57We are developing a new product using STM32F767 processor, with a microSD card for storing data. Page 1472 of the Reference Manual (RM0410) contains a description of the SDMMC data length register (SDMMC_DLEN). T...
Posted on January 24, 2018 at 05:25I am trying to read data from an I2C peripheral. This peripheral requires the I2C clock to be at 100kHz. When probing with a scope, the SCL line shows 400kHz. From the STM32CubeL4 I2C examples, the I2C_timing regis...
Posted on January 23, 2018 at 18:55I am using usart1 for asynchronous communication. Microcontroller is nucleo STM32F103RB.Here's is how I am receiving data if parity bit is not set,char USART1_Receive(){ if((USART1_SR & 0x00000020) == 0) // n...
Posted on January 23, 2018 at 13:24Hi STM community, Currently we are developing an application with STM32F779I eval board.I am using Cube Mx and System work bench for STM32. We are facing issue with RAM.My application uses FreeRTOS, FatFS and SD Ca...
Posted on January 22, 2018 at 21:58Hi, I've made a pcb using the stm32F446 mcu, 64 pin package, but I have a problem with it. I have four LED's attached to pa4 to pa7. Two of these work fine, but the ones on pa6 and pa7 only lights up entirely when ...
Posted on January 19, 2018 at 14:48Dear All,I would like to generate a 2 kHz �10 V Sine-wave with Hann window, as shown in the figure below. Do you have any ideal how to implement this function in STM32F4, and are there any additional circuits requi...
Posted on January 23, 2018 at 14:33Hello,I have been looking for a library for the ds18b20 compatible with stm32f0 and with the HAL driver but without success, so I decided to modify old one to make it compatible.this lib uses while loop delay, the ...
Posted on January 23, 2018 at 10:37I found a strange behavior of the STM32L NUCLEO cards. I installed a sensor network using Contiki and I implemented an RTC. If I try to set RTC_SYNCH_PREDIV to a value above 1023 (for example 2047, 4095, ... up to ...
