SPI data Issue with SPI_DATASIZE_8BIT
Hi,I'm facing an issue after configuring the SPI1 of STM32G491REI6 MCU using STm32CubeMX for SPI_DATASIZE_8BIT. I have captured the signals on the Oscilloscope after Transmitting the followed three-byte (0x03, 0x00, 0x50) from master(MCU) to slave. y...
UART RX does not work after changing clock from HSI to MSI
MCU - STM32L431RC; HAL drivers ver 1.13.After switching clock from HSI to MSI 16 -> 32 MHz,CubeMX generated system Clock setup does not work.When trying to send data to STM constantly getting "Noise error" and rarely 1st byte is received via ISR. TX ...
Reading more than 8 ADC inputs using interrupts on G070 MCU
Hello, I'm trying to read 9 ADC inputs on the G070 MCU using the interrupt method. Unfortunately, under the number of conversions setting I can only do 8 conversions. Is there a way around this? hadc.Instance = ADC1; hadc.Init.ClockPrescaler = AD...
Resolved! I want to use STM32G series for SDIO, so that I can use eMMC card. we can not use other stm32 controller.
Dear Sir,we are using STM32G series controller in our project but the problem is that we are also using eMMC card with 4GB which work on SDIO connectivity.could you plese share me which STM32g series will be suitable for it.Thank you
On STM32L475 using UART4 with DMA ring buffer after calling function HAL_UARTEx_ReceiveToIdle_DMA UART generates frame error.
Sometimes DMA is setup prior to frame error interrupt, sometimes after frame error it is not clear to me why. Problem is when frame error is detected after dma is set up then "HAL_UART_IRQHandler" function executes "UART_DMAAbortOnError".I can not de...
What is the maximum external pull up resistor on a GPIO in order to minimize power consumption?
Hi.I want to use interrupts to wake up from STOP2 and minimize the power consumption.The internal pull-up of 30k - 50K leaks about 100 uA when pulled to 3V3, so I was wondering how big can be a pull up in order to minimize this consumption. Ideally, ...
Resolved! STM32L412 : Could we used the SPI interface control the 5V LED Driver IC.
Could we used the SPI interface control the 5V LED Driver IC?STM32L412's VCC is 3.3V, SPI's pins are FT_f type.LED Driver IC's VCC is 5V.Is there anything that needs extra attention?Will there be problems with SPI operation?
Resolved! TSC measurement after exiting STOP mode (Abnormal delta)
Hi,MCU: STM32L072MCU is using TSC and ST touch sense library. When there is no stop mode involved, the measurement delta of no pressing is normal (-1, 0, 1).If MCU enters stop mode and then exits stop mode for touch sensing measurement, the delta wou...
Resolved! Minimum pulse width for STM32F2 timer in input capture mode.
I have a low frequency (~1 kHz), low duty cycle signal that I'd like to capture rising edges of. What's the minimum width of those pulses to capture them using a timer in input capture mode?I see there's a programmable digital filter there, in terms...
