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 ...
Is it possible to use the complementary channels as input on the TIM4 of the STM32F407 MCU? If so, how?Thanks,Alex
