Using an STM32F030F4 20-pin for a battery powered application with just a low quiescent touch tensor (active high) for wake-up from low power stand-by on low-to-high and high-to-low sensor edges.
I'm considering an STM32F030F4 20-pin for a battery powered application. Might a low quiescent touch sensor (output high) in conjunction with the timers/functions onboard the chip be used to wake the chip from low power stand-by on the rising and fal...
We use STM32F767NIH and see random QSPI interface failure accessing a flash.
We use STM32F767NIH and see random QSPI interface failure accessing a micron flash. The failure happens when we run diagnostic sw in a loop that does a write, read back and verify function. Using a protocol analyzer, we notice that when the QSPI fail...

Do i need a license to produce the clone of 32f746gdiscovery ?
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 ...
