Resolved! The RTC on my STM32L476RG MCU does not reliably cause a repetitive interrupt.
I just had a problem where my RTC timer did not fire the callback as it should. Most of the time it works fine, but yesterday on a customers system, it did not. The log shows the callback occurred, then the callback reinitialized the timer (in Start_...
Resolved! ADC Values conversion is not proper whenever with DMA Multiple Channels ?
Hello Support Team,Im using ADC1 DMA Multiple channels for conversion of Analog Data.. But after Reaching 3.2 Volts ADC Binary values will be Constant or 4096 only.. It is not converting as per variation with respect to input to ADC Channele after re...
Resolved! how to verify the fake STM32 MCUs?
Resolved! UART Transmission, Interrupt vs DMA
I am working on a project using UART communication and I have a question what is really different between interrupt mode and DMA mode in TX except for their underlying mechanism.(HAL_UART_Transmit_IT vs HAL_UART_Transmit_DMA)I know DMA uses the DMA c...
HAL_UART_Receive() Polling Mode: Only picks up first character from UART
Hello,I have a GPS module that prints of NMEA message strings in standard ASCII format at a rate of 9600 baud. This module is connected to usuart1 on my micro.It appears that only the first character is ever caught by the system, and anything followi...
Resolved! Only allow ONE type of interrupt to interrupt critical functions in my code?
I am working with the STM32L4 and STM32F4 microcontrollers and compiling with CubeIDE and System Workbench. I use no realtime operating system, I have no semaphores/mutexes, but I'm allowed to write code in C++. Every once in a while I want to execut...
Resolved! ADC_IN0 on F030K6 not reading 3V3 voltage_divider
I'm pluging into ADC_IN0 1x pull-up and 5x buttons, that when i pressed some button, it adds a resistor to ground and make a voltage_divider... then i read the value on ADC.But when i pressed the button, however, my ADC shows 0 on the variable and no...
Resolved! Possibility of enabling and disabling the channels of ADCs during runtime
Hi community members, I have tried to find the answer in the available documentation but could find the exact answer to my query. I have been using STM32-Nucleo-G474RE and I wanted to assign specific channels of ADCs to sensors X and other available ...
