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...
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?
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...
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...
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...
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) ...
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...
But will it stay available and what about other STM32 ICs.
We are running the STM32G473 micro and are using an ADC channel to read the various bus voltages (3.3v, 5v, and 24v) as well as motor currents. All the ADC readings are lower than they should be, but not by the same percentage.I am pasting some samp...
Hi,I am using ADC of STM32H743ZI which is configured as 16 bit, ADC clock =36.5MHz,Tsampling=1.5cycles in continuous conversion mode . I am using DMA technique to collect the data using a buffer size of 4096 in circular mode.The input is sine wave o...
