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...
Please show me my design mistakes. I was guided by AN4488. The electrical circuit is attached in the files below in pdf or jpeg formatThank you!
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
Hello St Forum! Good to be back at it for another little project here. Good to see familiar names.SPI Going to try and match up an STM32l476VG using SPI to a Ethernet widget. Widget says it can use SPI and apparently it (widget) will auto increment a...
