Hello!I have to build a system that throws data simultaneously to 6 16-bit ports. It should be bit-accurate, so I was thinking about preparing all the DMA channels with one single timer, and when everything is ready, start the timer. I already did th...
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...
