Hello!This is the first time im using NOR Flash so bear with me :)Question #1I screwed up and forgot to add a pullup for the open drain ready/busy NOR output.So i've tried the ghetto approach of using the internal pullup of the STM32 as "busy wait" b...
Background: F429 works as a net node in the ethernet switch. Other nodes are cortex-A or CPU, so the controller with F429 has the poorest capacity for processing net data flow.Current Implementation: As the controller only exchanges data with a speci...
How to output CLK for receive-only (master) in SPI communicationWe want to create a receive-only (master) in SPI communication.However, SPI_CLK is not generated.In the case of a transmit-only (master), I think that CLK will be generated if CLK is ena...
Trying to write a i2c driver for the stm32f0 and having trouble understanding how this works as im use to the stm32f4 i2c could anyone describe what steps i need to take to write a polling i2c driver or point me to an app note that describes ive ben ...
I checked with the Uploaded File schematic board. I'm using STM32CubeProgrammer. Connect from PC via UART. I confirmed that the UART is connected with STM32CubeProgrammer. Software has not been written yet. In that state, the MCU became so hot that...
Hi I am using X-CUBE-DPOWER to set the parameters for my Buck converter operating conditions on a B-G474E-DPOW1 evaluation board. I am trying to understand how the controller is implemented. For the PWM switching frequency, I know that this is done b...
Hi all,I was reading through the documentation of the STM32H723 to find out what clock speed I can configure the FMC to run at using an external SDRAM. Looking at older posts and videos there is mentioned 100 MHz, but when I look at the newer/revised...
I have read AN4991 and the example code but in my case nothing works. I'm using DMA transfer with the UART. Can that be the reason? Is it not possible to wake up from STOP1 when using DMA to receive bytes from USART? Or how can it be done?I use C...
Hi all,My goal is to have position independent binaries for my application (on an STM32H7) so that I can update the device while running out of flash (swapping between two different program locations).I followed this tutorial: https://techblog.paalij...
This is a problem about the STM32H745XI-Disco control external AD5791 through SPI. When using Debug to detect the serial port output, the result is consistent with the desired result. However, when using a multimeter to measure the output of the AD57...
