Summary: A 10-character message is sent through the interface (It uses RS485). Then, the first character, "h," is received by the processor and verified. If it is confirmed to be the character "h," the remaining 9 characters are received. After verif...
I am trying to get the ADCs operational on my board that uses an STM32F030C8 processor.PA0 pin analog seems to read OK ~2200 which is approx OK.Reading CH16 and CH17 (Temp sensor, VrefINT) always return a value of 4095.Main() we call the Init MX_AD...
Hello, i want to use the FM+ mode on a STM32L412 GPIO pin to reduce Vol max for a given pin sink current of 8mA. MCU VDD is 2.5V. I'm well aware of the max current capabilities of any pin and will not violate any.In this forum i read:For all I2C2 pin...
I have a project that uses the ModuleX middleware and has been included into the build. However, I am stuck trying to figure out how to create a sub-project to build the Module code. Thought that might be in the New>STM32 Project wizard but it alwa...
Good day,I am using Windows 11 running Keil software, STM32f303ze, when i select the ST-link setting, the software shuts down, I cannot debug it as soon as i debug it shuts down.can i please be assisted
STM32L4P5-DK is a STM32L4P5AGI6PU based microcontroller, but I could find STM32F723IEK6 and STM32L152CCT6 IC's are also available on the DK . May I know the purpose of these 2 MCUs other than the main MCU?
Hi buddies, I'm very new to the STM32 series as well as STM32CubeIDE. I created the toggle LED program for STM32F769I-DISCO(I'm currently working on this). Before generating the code I just choose the PJ5 pin(because this is an onboard green led ). ...
I'm trying to change the PLLxFRACR on-the fly. Per the reference manual something like this should work:__HAL_RCC_PLL2FRACN_DISABLE(); __HAL_RCC_PLL2FRACN_CONFIG(8191); __HAL_RCC_PLL2FRACN_ENABLE();On a STM32H750 this code seems to have no effect. Bu...
I have been reading the RM0351 trying to figure out how to setup the clock source for the ADC.The reference manual says that I could choose the system clock, PLLSAI1, or the PPLSAI2as the asynchronous clock source for the ADC (see figure 1). It also ...
