If I set my sine wave generator to 1.5 Vpk-pk the DAC outputs a nice clean sine wave. If I increase the ADC input above that level, I start to see clipping of the sine wave. The negative part of the wave begins clipping before the positive part. Is t...
I have already done this before, but with an Arduino board, the settings of Xbee are similar right now with STM that when I worked with Arduino, but I´m in troubles because I´m reading data from ADC board, but when I send it, the PC doesn´t receive a...
Hello folks,Does any body know why the input pin can not be driven high enough when it is set as the trigger to TIM3 in OPM? I use CubeMX to generate the init code where TIM3 ch1 as input trigger and ch2 as the output. On the board, I use a comparato...
Hello,I'm exploring the low power modes with a NUCLEO-L476RG (STM32L476RG).I generated RTC and NVIC configurations with STM32CubeMX (5.3 and then 5.6).I am able to wake up from STOP0, STOP1 and STOP2 using the GPIO EXTI interrupt of the user button.I...
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...
