I'm simulating some issues on my STM32F412 DMA SPI SLAVE because I need to avoid any unrecoverable situation.If for any reason the TX is not empty (TXE is 0), I'm not able to reset it (set to 1) even reinitializing the peripheral.Probably, something ...
Hi all,I interfaced external(off board ADC) to stm32h743 microcontroller. i am receiveing data in spi interrupt mode. i enabled RXPIE interrupt.But the interrupt latency is increasing as Baud rate of SPI is increased.at lower speeds latency is small(...
Hello,Is it that application can only run from ITCM ? When I try to run from other SRAM such as SRAM1, it get into MEM IRQ handler.Another issue is that on running from ITCM the HAL_Delay is much faster compared with running from internal flash (Xip...
I am using internal ADC of STM32F779NI connected to LMT86 Temperature sensor. Vref is 3.3v and ADC resolution used is 10-bit. The problem is there is always a difference with the expected ADC and the actual ADC for a given voltage. This difference is...
I'm using stm32f103ze to send some data over the serial peripheral, but it didn't work. The settings are correctly set but when I try to write to the data register it always remains zero. Furthermore, none of the Serial peripherals seem to work. Wh...
I'm hoping this is a simple question. In the reference manual (RM0394 section 39.4.5), the tolerance of the LPUART receiver is specified in Table 204. For example, with BRR = 1024 and 9 bits/1 stop bit, the tolerance is given as 2.33%.I've been ass...
Hi,This is to request clarification on doubts regarding the storage of data in the non-volatile memory of the STM32G030C6T6 micro controller ... from what I see in the micro controller's technical sheet, it does not have EEPROM memory, since FLASH me...
Hi,I am trying to get some clarification on the accuracy of the STM32L4's HSI16. AN4736 mentions that the HSI16 will leave ST's factory calibrated to [-0.75%, 0.5%] at 30 C. DS11453 section 6.3.8 shows that the drift over 0 to 85 C will be -1% to 1...
I want to implement a timer which would elapse in 3s and gives me an interrupt then. But i want to build a kind of software watchdog which will be always reseted from an external clock 1s. So my idea is, when the external 1s clock is off then after 3...
