Hey guys, I'm a bit confused in using the ADC in differential mode. I've got a shunt resistor and want to measure the voltage as exact as possible. One side of the shunt is connected to GND, but with higher currents, this GND is not anymore GND (it's...
Hi,I have purchases STM32L4R9AI Discovery Kit, It has Macronix Octa Flash (MX25LM51245G).I am trying to read the device ID In OCTA SPI Mode but unable to achieve the same.Does any one has the code or the LAB Tutorial on the same.I have gone through A...
I have set up a timer to generate a given waveform using the capture-compare register, fed from DMA. The OCxREF output is set to TOGGLE mode. The waveform consists of a pattern, repeating n times, after each ARR update. A new pattern is loaded into D...
I have a basic question on signal definitions used in the Ref Manual. The section on DMA interconnects refers to TIM3_UP, TIM3_UP, etc, and TIM3_Ch3/UP.First question: What is UP? This is not defined anywhere. Does it mean TIM3 gets updated? In CubeM...
I keep getting OVR (overrun) interrupts when running below simple code.OVR interrupt happens every 10~20th iteration of the loop. Overrun should not occur because the data register (DR) is read after measurement is completed.Why do I get an overrun a...
Hello I'm using the STM32F767ZI part.I have the following DMA initialized this way: // TIM1 CC2 event dmaCC2.Init.Direction = DMA_MEMORY_TO_PERIPH; dmaCC2.Init.PeriphInc = DMA_PINC_DISABLE; dmaCC2.Init.MemInc = DMA_MINC_DISABLE; dmaCC2.Init.Perip...
Posted on January 19, 2018 at 16:19I have been using Keil IDE for years (as a hobbyist).Maybe someone who knows both Keil & TrueStudio could share some details about pros & cons.I know that the primary difference is lack of licensing limits in TS (K...
Hi! I use embendded ADC1 channel 3 in STM32H743VIT6 for sampling data. Input in differential mode. For improve SNR i added capacitor 47pF parallel to diff input pins see fig1. Also this capacitor required by AN5354 This led to decrease noise floor l...
I'm using stm32 MCU to interface with mcp4821 D A C . The MCU's spi data size is set to 8 bit mode.The D A C has a 16 bit register and (Starting from 0) bit 12 to 15 are configuration bits and the remaining bits are data bits . My problem is ...how ...
Hi, just want to know if it is possible to switch the interrupt between Character match and Each character received interrupt on the fly without stopping the UART ?
