Hi everyone,I'm using STM32L4R9 to develop product which run on RTOS kernel. Previously, I used a other Cortex-M4 chip run on RTOS platform in tickless mode, a 32 bit timer counter is used for calculate RTOS tick and this timer-counter able run on lo...
Posted on December 09, 2016 at 17:12Hi,After playing with the STM32F746G Discovery for a while I decided to get a Waveshare OPEN746I-C kit with a 7 inch LCD with capacitive touchscreen as I wanted a bigger screen and access to more of the pins.I've ...
Posted on March 02, 2015 at 01:34Hello,I would like to give external oscillators (TCXO, VCXO, etc) a try as HSE but can't find any diagram or documentation about it regarding STM32(F427). Could you please help with these three questions : OSC_IN ...
In auto baud rate situation is there a way to know the actual baud rate of the uart, anthe the other parameters linke size and parity?huart1->Init.BaudRateseems to have the initial parameters but not the actuals.
Hi, I am running an STM32L4 on a custom board with a 64mb PSRAM attached to it. I can write to any address on the PSRAM however I want to store a large array of sample data on the PSRAM itself. Basically, I want to do something like this int a[4] = {...
It's my first time to use STM23L031F6P6，and i got some troublesboth UART2 & LPUART1 don't work after resume from STOP modeis there somebody can help me？main code shows below：void test1(void) { HAL_Init(); RTC_Config(); ...
I have a problem on a STM32F071C board. The PLL will not reach ready state. I am using the HSI and in order to reduce current consumption I want to devide PLL from 8MHz down to 2MHz. This works fine on most board (18 out of 20) but on some the PLL_RD...
HelloI am using STM32F100C4T6B and i want to read information from my module GY-50 L3G4200D using I2C and sending it by uart to my computer. I can not do it by SWD. Im using STM32CubeMX and System Workbench for STM32. I know for sure that communicati...
Posted on March 03, 2017 at 12:55Hi, has anyone written a high performance STM32F4/F7 SDIO/SDMMC driver using DMA for FreeRTOS?I am currently converting my complex audio application from bare metal to run on freeRTOS but am still faced with STM's po...
Greetings ,I am running STM32F030R8 at 48 MHz. I want to generate timer interrupt every 10 uSec or say 50 uSec. The PSC is 16bit wide which means i cannot go less then 1 ms delay for timer interrupt. Is there any other method with which i can achie...
