I have a project which uses both OPAMPs. For both OA I use dedicated VINM pin.OPAMP1 works correctly.OPAMP2 behaves like the dedicated pin (M2 ball) is not connected to the input multiplexer.I 've tried - mode FOLLOWER: OK - mode STANDALONE, reconnec...
Hi,I am working with the STM32F103RCT6. I am writing a bare metal code for delay function using SYSTICK timer. The problem I am facing is that I am not able to write to the ARM cortex registers. Below is my code for your reference - This is the stm32...
We're using the ADC function built into the STM32F767.The problem is that when the analog signal input to the ADC is around 200mV, the digital value output from the ADC appears to be around 240-260. We're trying to obtain a stable value by collecting...
Hi Team, I am planning to use STM32L476RE MCU for my project, Can I know how to switch between Stop1,2 and low power sleep and run modes? I am new to STM32 and I need a reference code or some guidance to start with, any help very much appreciated. Th...
We are developing a product that needs the ability to run 3 separate CAN interfaces connected to 3 separate CAN buses. I have the NUCLEO-F413ZH and I can successfully initialize and start CAN1, CAN2, and CAN3 and transmit from each of them in a sing...
Hi,Im just getting my new STM32N6570-DK and I try blinking simple led project first with default generate.But when I built and flash it, it got stuck when init UCPD (pic 1), am I missing something ?When I checking seem it still not define yet (pic 2)...
Hello everyone, I am using the STM32F042K6 for a small project where I don't have much space. Therefore, I rely on the small package and the "crystal-less USB" function. The hardware arrived today, but unfortunately, I had to realize that the USB li...
"C5" typo corrected in title to "C0"Does have the STM32C5 and STM32U5 microcontroller documents e.g hardware user manual?Could you please help me to confirm this?
Hi, I don't understand why CubeMX is limiting me through their IOC file to select an ADC clock below 2MHz. The datasheet says 140 kHz is the minimum ADC clock frequency for the STM32G07. Anyone has any answers or help ?.
Hello,I had two related questions to clarify - 1. Can multiple Op-Amps be used in the differential mode simultaneously and their output fed to ADC for measuring input DC voltage?2. Also, since the Op-Amps inside the STM32G4 MCU are not rail-to-rail, ...
