Category device type for FLASH
I am using an STM32G473MEY3 MCU. I am looking in the reference manual in the FLASH section, but I am not sure if this is a cateogry 2, cateogry 3, or category 4 device. I am thinking category 3. Any ideas?

STM32 G0B1KEU6: Using LSI as clock source
I am trying to use the LSI as the clock source on the STM32 G0B1KEU6. It doesn't work, and as soon as I select the LSI in the MUX on the clock tree, my code stops working. To ensure there are no other sources of error, I used the exact same code but ...
Resolved! Two nucleo boards (stm32f446re) and (stm32h723zg) communicate through CAN in Classic mode.
Hello, I am attempting to have a two stm32 nucleo boards communicate by sending and receiving can messages. My goal is to have the PA5 LED of the STM32 f446re blink when a can message is received. I know that the canbus must be configured to classic...
Resolved! H7: TIM1-triggered DMA and TIM1-ADC-triggered DMA get out of sync at Debug Halt
Hi,in a setup on STM32H725 where TIM1 ETR triggers several DMA activities, I observe an effect while debugging that I would rather like to avoid:Looking at the NDTR of the three DMA, it seems that one extra ADC run (or at least the related DMA transf...
Resolved! Looking for Compact, Low-Power Alternative to STM32F401CCU6
Hello everyone,I'm currently using the STM32F401CCU6 in my project, but it's proving to be oversized for my application, both in terms of physical package and power requirements. I'm hoping to switch to a smaller STM32 microcontroller that maintains ...
STM32F373 SDADC Output is always 32767
Hi all,I am trying to activate SDADC on my custom designed board to measure a couple of analog voltages. I am trying to measure 5-channels in injected continuous mode. Offset = 0, Gain = 1, Single-Ended Offset Mode. See the CUBE settings below :In th...
FMC NOR Ready/Busy
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...
Data Flow Processing Capacity of STM32F429 Ethernet
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 communication
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...
