The data sheet on page one shows 0 to 3.6V input range but rm0440 says the ADC input range is -Vref to +Vref.where I believe the Vref is 3.6V? Can you explain the difference in specifications? Also, can you explain how this range changes with being s...
Hello, I am trying to transmit 64 byte data with DMA but if I am not use at least 10ms delay the data is not transmitted. How can I check the is data transmitted without any need of delay ? I try to check UART is busy or not fort that but its not wor...
I have found an issue with code generation from .ioc file. Using STM32H7S78 DK when choosing pins for FDCAN2 (I chose pb5 and pb6), after code generation it doesnt set pb 6 as an RX. Even if you manualy add it in the code it will remove it after code...
Hello, i have a question about the stm32h723. I tried setting up the CAN peripheral and it's not working. I absolutely don't know why. Can anybody help me out please? My Sourcecode looks like the following:/* USER CODE BEGIN Header */ /** *********...
I'm trying to use circular DMA with a SPI bus peripheral, where the DMA transfer complete interrupt causes something to happen after each block of data is DMA'd to the SPI bus. If my DMA transfer size is greater than 5, everything works well accordin...
Hello -I recently acquired a new P-L496G-CELL02 development kit to evaluate cellular communication performance. Out of the box, when I first plug in the P-L496G-CELL02 development kit to my PC and open a terminal, it instructs me to "open a web brows...
HICan anyone have example how to configure and use multiple ADC channels in STM32503 microcontroller.i have seen in a video to use DMA, but how to configure and use it.anyone please suggest and help.
Hello Team,Currently we are using STM32F746NGH6 MCU. But we want 2Mb flash memory in same series. But in same series there is 2Mb flash memory is not available.So, we are checking about STM32F779NIH6 or STM32F777NIH6. Can we directly replace STM32F74...
Regarding the KNX TP, I tested the STKNX evaluation board and my board which have ST-KNX chip then have below questions: Q1, The testing connection is UART TX => KNX_TX (STKNX EV1) => KNX_TP line => KNX_RX(STKNX chip board 2) => UART RXCH1: KNX...
I have not seen displays with 1 data Lane MIPI but they are always 2 data Lane MIPIbut some STM chips have only one 1 data Lane MIPICan it be somehow connected like grounding the remaining line.
