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...
hi, i am using stm32f103c8 development board, wiht that i worked out many concepts. its peofromance was so good. now i am working with bxCan , initially i tried loopback code, it was done. while moving to normal mode , no desired output...please ...
Hello,I am struggling with nor flash issue on stm32h743 eval board.I hope someone can help with this.1. On using the stm32h743cube example for FMC_NOR the example fails!2. I then changes the timing (increased all parameters) as following (there is no...
Hello, I am using STM32F070*B Nucleo board want to flash the device using Flash Loder demonstration software using UART communication. but this type of warning message came. Link that i am following:http://stm32f4-discovery.net/2014/09/program-stm32f...
Everytime i wake up from stopmode i print my RTC time. However whenever i do that i print some weird symbols instead. Im using the STM32L053R8T6. I just used:printf("%d-%d-%d\n\r", Hour, Min, Sec); HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_...
I entegrated state machine of JTAG TAP in a mcu for control stm32f103c8t6. It is working well. (IDCODE registers are 0x3ba00477 = CORTEXM3 , 0x16410041 = STM32f103c8 medium lqfp48)But I haven't found any file for programming flash memory with JTAG...
I have two peripheral where one works on 8-bit mode and the other on 16-bit mode. What could be the best possible solution for such situations?
