Hi,I have the following code to enter shutdown with UART interrupts for the wake up. The processor does shutdown briefly (confirmed with power measurements) and then wakes up after ~.5 seconds. I cannot see any traffic on the serial ports and I can't...
I have 2 memories with not the same type the first is hyperram and the second is nor flash and it is mandatory for my project to use both of them.i am not sure how to do so or if is it possible to use one on the st board and link the other one separa...
using STM32H743ZITWe are using all the serial ports (i.e) 4 UART and 4 USART and all is good. In addition to the UARTS we are using thre I2c, and CANWhen attempting to add the LPUart1, the initialization fails. There is no pin assignment error etc. ...
Hi! I am discovering the world of STM32 and currently using a STM32F4 to establish a UART communication (send and receive data). I wrote a pretty basic program to send and receive a message (basically a loop) with a baud rate of 9600. The users manua...
Using an F411, I'm having trouble getting the RTC_AF1 (PC13) pin to trigger while powered only by the VBAT pin. The pin seems to drive correctly when VDD is active (tried both Wakeup and Alarm A), but removing VDD does not have the same effect. Is th...
HiI am trying to test STM32H747I-EVAL and LCDMy questions are as belowsAre STM32H747I-EVAL and LCD connected with RGB Connector? ( I want to connect each other with RGB connector when I design a circuits for STM32H747 with LCD) I ...
I'm considering using STLINK-V3MODS for RS-485 via VCP. For it I would need DE (Driver Enable) functionality. (Something similar was commented in an old question)In the user manual, when UART bridge is described it says:"UART signals with hardware fl...
Posted on September 18, 2017 at 16:07I see that this has been asked a few times with no real resolution or workaround, so I'll ask again please?I have USART3 configured at 9600 Baud. I test this with a terminal program also set at 9600 and it works ...
I connect my I2C but when I connect an oscilloscope I have nothing on the clock signal. So probably I misconfigured my clock. Could you give me the information? Thanks in advance. In this picture below I've a warning, do you know how to remove this w...
STM32H750IBK6 REV V sample what is max FMC CLK we can run SDRAMthe datasheet says 2 different values for rev V and REV Y IC revision what is safe area of operating FMC CLK with SDRAM
