How to see a graph from an array?
Hi all,I'm taking a lot of readings from the ADC, and store those reads in an array (reads[2000]).Is there a way to sohw a graph from the reads, using STMStudio or another program?

Regarding SPI DMA Rx issue when using SPI 8 bit mode
Hello,I have had an issue with SPI Rx DMA. In short, I recieve twice as many bytes as I expect when using SPI 8 bit mode (STM32CubeIDE setting), but not in 16 bit mode.A brief description of the project:Im using an external accelerometer with 220ksps...
Is STM32H743ZIT6 multicore or not
When I read the datasheet, the introduction doesn't mention the number number of cores. Digikey says this is a multicore chip. Mouser doesn't either talk about multicore.Several pages down (14) on the datasheet I can read that this is indeed a multic...
STM32F412 - I2S(2) Full Duplex With Two Transmit Channels Can't Be Fully Implemented?
I am developing an audio processor product that requires 8 audio output channels. I intended to use I2S2 and I2S3 for 4 stereo Tx pairs. The other I2S interfaces are used for other functions including audio input channels.I had to work around the H...
STM32F446ZE doesn't enter in Standby mode
Hi,I am using Standby mode on STM32F446ZE, but I faced with a problem. Sometimes MCU doesn't enter in this mode. Exiting Standby mode via RTC wakeup.Below is present steps which I perform for entering StandbySCB->SCR |= 0x00000004;PWR->CR |= 0x000000...
Resolved! PWM capture using Rising, falling EXTI
Hi all,I am capturing 10 pwm pulses from proximity sensors by making the all pwm pins in rising falling interrupt mode.PWM is captured by a timer at every 100us interrupt.some times pulses are missing, I don't know why this is happening.I am sharing ...
How to use Rotary Encoder effectively in external interrupt
Hi there this is Akash, I am doing a project on STM32F100RB Discovery Kit, in this project I am controlling stepper motor with some parameter given by the user using rotary encoder, basically I want to run the motor in the while loop, and through ext...
Is there a limit on how many bytes to send over I2C from the slave? The MCU is STM32F469NI, and I have programed the board to act as an slave, it works fine if amount of data sent from slave is less than 100 bytes, but data gets corrupted if sent more.

STM32F746 QSPI interrupt firing continuously with no apparent interrupt source
Hi,I'm trying to use the QSPI peripheral on the STM32F746, specifically on the STM32F746 Discovery board, however, as soon as any QSPI interrupt is enabled there is an interrupt present but upon reading the status registers there is no visible interr...
