Hello there!I'm working on a custom project, using STM32H750VB with the main app running on an external flash (developed on TrueStudio and HAL 1.7.0). I'm using two EXTI pins to get the data from a RFID reader, using Wiegand 34 protocol. Basically th...
hey there.for a while ive been tryin to copy some codes from flash to internal sram and run it.ive read the datasheet, programming manual and cortex manual and they all confirm that it is possible to run code from sram, however when i copy the codes ...
Hello Community,I'm currently programming a framework for the STM32F3 ADC. However I ran into a problem. I want my ADC to run continuously. Moreover I expect "long" delays between reading the channels. I thought, this is no problem, since the ADC has...
Hello,I am interested to use the ITM/DWT over SWD to output trace data and observe structural coverage during test. My debug tool says that the microcontroller must support ITM and DWT. I am using STM32L433CC (LQFP48 package). In RM0394 section 46...
There is a scenario in my application where a UART FIFO overrun can occur. The application can handle dropped packets, so this is not a concern. The issue is that when an overrun occurs, the UART stops interrupting when new bytes fill the HW FIFO. I...
i am try to interface the STM32F103C8T6 with GSM & usb to Serial converter (Multi USART). But in GSM AT Comment Response Data Length is Different for Each & every time. I don't know how to handle the UART Receive with unknown data length Pleas...
Hello, I see ADC examples that use the following functions:1.HAL_ADC_PollForConversion.2.HAL_ADC_GetValue.Questions:a. What's the difference between both functions ?b. In my application I simply want to get the ADC voltage when a user sends a command...
Hi,I am using STM32L051R8T6 and i have implemented an SPI slave using the HAL libraries. I am using DMA. the master is an FPGA. SPI clock is ~2Mhz. The FPGA initiate 2 read commands for each read from the MCU - 1 for it to prepare the data and 1 to r...
Im trying to write code that will average samples from the ADC of an STM32F01K6. I am starting a conversion and waiting while the conversion takes place by writing a while loop which checks the finish flag ADC1->CR |= ADC_CR_ADSTART; while(((...
