Determining RAM size at Runtime?
There's the Flash Size Register in the Device electronic signature. Is there an equivalent for the onboard SRAM size? Any way to get the ACTUAL SRAM size at runtime?

Resolved! ADC(with DMA) doesn't work when I increase its frequency
This has been a reoccurring issue for me, whenever I raise the ADC frequency above 0.25MHZ the while loop gets interrupted, and when I use frequencies below that the ADC resolution drops to 8 bits for an unknown reason. Is there a way to fix this wi...
Contents of the unique device ID registers LOT_NUM
I'm using STM32L031E6Y6 for a high volume low cost product and I'm hoping to arrange it so that even if my firmware binary were to be stolen, it could only be used to produce a limited number of counterfeit products.I can cryptographically fix the fi...
Could STM32L433's SAI achieve features similar to full duplex?
We need to transmit and receive I2S data at the same time.But we can’t transmit and receive at the same time now.Then we want to know whether the SAI of STM32L433 can achieve features similar to full-duplex?If yes, is this setting correct?
Resolved! STM32G0B1KBU7 (UFQFPN32) and clock for FDCAN peripheral
Hello,We are planning on replacing the F042 (TSSOP20) with the G0 cited in the question.At the moment the F042 use a HSE crystal of 8MHz in order to get a precise enough clock for the CAN peripheral.Parsing the datasheet of the G0B1KB, there is no wa...
Experience with oddly silkscreen STM32s?
Got a new batch of micro's from a broker due to the chip crisis. They work and soldered down fine, memory matched, bootloader, etc. The concern about these MPU's is the silk screen and die marks are quite different.We have never seen die marks on the...
What is good to use for a “monitoring system�?? That is also going to have video feeds?
I want to create a localhost that my client can easily see a custom page on, that is displaying all the data from fish tanks. Such as, temperatures, water levels and more. What products would be ideal to use? A NUCLEO-f767Zl??? BUT, then theres the a...
STM32H743ZI UART Tx with DMA doesn't want to turn on
Hi guys, its been a while and I hope everyone is well and safe.Using a STM32H743ZIReference Manuel I am having issues turning on the DMA1 stream associated to the UART4 Tx, in this case DMA1_Stream1. The DMA is setup as a One Shot mode (Normal Mode) ...
STM32f746G_DISCO board sdram configuration quesiton
Hi, In the STM32F746G_DISCO board, FMC_SDRAM example, how to decide these parameters? Which section does it specify from sdram MT48LC4M32B2B5 datasheet? SDRAM_Timing.LoadToActiveDelay = 2; SDRAM_Timing.ExitSelfRefreshDelay = 6; SDRAM_Timing.SelfRe...
STM32H part in Digikey stock
But will it stay available and what about other STM32 ICs.
