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(((...
Hello all,I have been using Atollic and the STM32 for a long time.I just created a new board with an STM32L151CB MCU.When I try to go into debug mode with Atollic, if the MCU is blank, I get this message.If I flash the MCU with STlinkUtility, and the...
Hello,I think I found a possible error in the STMG4 reference manual RM0440 Rev 4, in Table 97 of section 14.3: in the IVT address column, the addresses from 0x0000_0198 to 0x0000_01A4 appear two times, instead of continuously increasing (entries 86...
Checked PWR settings at startup.Find PWR->SR2 status value 0x00000300.According manual this tellsRegulator in Low Power mode (LPR)Flash memory in power downIs this initiated by Keil/ST-Link debugger?Or are there errors in reference manual of register...
Hello, I am designing a Buck converter to control two Peltier heating or cooling mode. I found nothing available from market, so I designed mine. Target stable temperature, logging and alarm. It control a vaccine VET fridge, stable control temperatu...
