Hi,I'm using a NUCLEO-G491 board with a G491RET6 MCU.To test the DAC, I created a Triangle signal by incrementing a variable and writing it to the DHR12R register. However the top of the Triangle is cut-off and the maximum voltage on the Pin is 3.45 ...
Here is the software setting:For STM32H735(STM32H745 is the same but with different ID):-Defines:/* USER CODE BEGIN PV */FDCAN_TxHeaderTypeDef TxHeader;FDCAN_RxHeaderTypeDef RxHeader;uint8_t TxData_Node1_To_Node2[] = {0x10, 0x32, 0x54, 0x76, 0x98, 0...
Hello everyone, I'm an HW engineer and I'm quite new in the communication betweer mcu.I'm now facing a communication error related to FDCAN.My colleagues and I have made a system that needs to communicate with the outside world via FD CAN, working on...
I am reading the data after sampling 2048 each 3 times.But is there a reason why sometimes the data is read as 0?The cube mx configuration and part of the code are as follows.please help thank you
I note in the post (from July 31, 2020 at 8:33 AM) entitled "FLASH_WaitForLastOperation CubeMx error" (here: https://community.st.com/s/question/0D53W00000EDrjiSAD/flashwaitforlastoperation-returns-error-in-stm32g070), that there is a mention of an e...
Using HAL_UART_Transmit_DMAUSART is in async mode, 115200,8,1,-DMA: Data width = byte (nothing else works)Any clues as to what could be happening here?Thank you!Ned
Hi. I am going through the STM32 Step by Step instructions, as well as going through the "Description of STM32F7 HAL and low-layer drivers" manual. I am using the STM32756-EVAL board so I have made some appropriate changes based on the pins and ports...
Hi everyone,A new issue has occur and have no idea as to why the transmission would be sometimes corrupt. I try sending the word "Hello World" as a test, however sometimes I would receieve the word but sometimes I would receivbe garage values that va...
In the RM0454 the chapter 14.9 is "Temperature sensor and internal reference voltage". It explain how to compute the actual VREF+ using the internal reference voltage. And the ADC has a VREFINT channel.But I can't find VREFBUF.In the datasheet (DS127...
