Hello ExpertsNeed some help with serial portI have been trying to communicate on serial 6 with MAX485 on Siemens V20 VFD drive.When I send command on Modbus it is received by the slave and slave responses properly as seen in my logic analyser. But w...
Hello.I am using SAI of STM32F4 & F7 MCUs as I2S input/output.When configuring SAI as "master/slave receive" using HAL driver, "Clock strobing" is set incorrectly.Here is the corresponding code block of the STM32F4 HAL driver (stm32f4xx_hal_sai.c).HA...
hi all, when rtc overflow? this will happen in my use env. does the rtc counter auto reset to zero or stop count?
Hello!I can read any registers, but can't proramm it. This is my first attempt to work whith this flash in this KIT. Initialization - HAL, STMCube IDE. Code in main function after Initialization (initialization - auto generate in IDE):QSPI_Write_en_C...
Dear Members,How can I get exactly 1Hz interrupt from TIM3 ?I use STM32F4 Discovery and looking at TIM_TimeBase Example, but I can not get exactly 1Hz yet...ThanksCode :TIM_OCInitTypeDef TIM_OCInitStructure; __IO uint16_t CCR1_Val = 54618; __IO uint...
HiI am working on Redesign project. The existing controller is STR912FAWx. In this controller, CAN protocol has CAN_IDR register to identify the message objects causing the interrupt.Similarly, in STM32F4 do we have CAN message object to identify the...
Hello, I'm using STM32F7.I want to save data on F7 memory, where is not delete after reset. My data may has 1-2KB size.Anyone can tell me how to do that?I read and found that i can do with no init ram, but I can not find any tutorial or documents rel...
I was going to use the following code to protect the code for STM32F103, but functions that write OB (Option Byte) are not defined in the SPL structure.
I am using STM32H7 for about 2 years with stable HW an SW .after some SW change I found strange behavior .If the debugger is connected and I flash the application using ICD "ST-Link Ver3" the micro-controller boot normally.but the micro-controller ha...
I have a STEVAL STWINCSV1 board with an STM32L4R9 chip connected to my computer via USB. I am trying to use OpenOCD to flash a new image. I am using the command `openocd -d -f board/stm32l4discovery.cfg` to try to open a connection to the board. Here...
