Hey,I am planning an algorithm that needs to work in Real time.The system includes an ADC that samples in rate of 5Msps and the interface with the CPU is 80MHz in SPI.From primary calculation the running time Complexity is O(n log n), and the result...
Good afternoonLooking for a simple solution to add WiFi and/or BT connectivity to a STM32F4/F7 MCU..USB dongles are out of question as it would require to a Linux system...Seen that some people are using ESP32 hooked up to UART...but I am not sure if...
hi everyone, i would like to know if anyone has faced the same probleme : so i'm working with keil uvison5, i have build usart2 (PA2-->Tx / PA3-->Rx), everything works, and the message is printed correctly in the serial monitor, but when i'm trying t...
Hello,I try to construct a project but i don't achieve to do what i want.My MCU is an STM32G070CB an I use MDK Essential 5.28 (Flex) Version: 5.28.0.0 with Compiler V6.12.I explain my need :In my projet, my memory space is coomposed of a boot part an...
Hello,I have never done this so please be patient haha - I need to store around 10 float numbers into the flash memory - I will do this in the last memory sector. The problem that I have is that I can write & read to the flash but if i want to overwr...
Hi,I am looking to implement a secure boot system into an application. My product will only be updated OTA.I understand that when a firmware is written i need to hash it and create a digest and then sign it and add it to the hex file payload.Along wi...
Hi,Now, we use STM32G070RB.Please let me make clear about internal PU/PD resistor setting on PA8.Although we set internal PU res from GPIOA_PUPDR, measured voltage is near 0V at this port.We found this is because the PD res that is set by SYSCFG_CFGR...
i'm thinking about interfacing DHT11 or DHT22 (AM2302) https://www.mouser.com/datasheet/2/758/DHT11-Technical-Data-Sheet-Translated-Version-1143054.pdfhttps://www.sparkfun.com/datasheets/Sensors/Temperature/DHT22.pdfa thing i noted about both of them...
Hi!I am designing a microcontroller (STM32F405RGT6) circuit board with a minimal configuration.Is this a normal circuit that I developed?The microcontroller will be uploaded firmware on USART1.BOOT1 and BOOT0 are connected to jumpers. Please show me ...
I tried to search for Power Regulator Voltage Scale in several PDFs but found only power regulator. Those talks voltage levels and perfomance levels but give no numbers.I ask because I tried 200MHz with Scale 1 and the CPU was dead. I can program it ...
