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...
Atm im facing the Problem, that the mcu enters a previously activated isr but not as intended. Im setting up Timer and gpio interrupts but ending in an fdcan isr which redirects to the default Handler. Its Worth mentioning im Using hal/ll driver and ...
