STM32 MCUs Products

Hi, I'd like to integrate calypso protocol (Calypso Networks Association) in my STM32 project. Does ST (or anybody else) have a SW package which implements calypso protocol (Calypso Networks Association)? Thanks, Aviv

"undefined reference to custom function"

I am unsure of why this function keeps triggering the "undefined reference to function" error, especially since it seems to be able to find it perfectly well when I deliberately leave out arguments.The function in question is shown below:dc_init(DC1,...

The fastest way to reconfigure the ADC regular conversion sequence for stm32f4

Hello,I am working on project which contains reconfiguration of 16 regular channels ADC after end conversion sequence.Therefore, the registers ADC_SQR1, ADC_SQR2, ADC_SQR3, ADC_SQR4 and ADC_SMPR1, ADC_SMPR2 should be updated at the end of the sequenc...

Is there an easier way to search for micro availability (at distributors) based on peripheral requirements?

If I'm interested in the availability of STM32L4 chips that come in a LQFP64 package and also has a DFSDM interface, I use the "View all STM32L4 series products" and select the appropriate filters. I then get a list of 17 different micro variations. ...

stm32 pwm signal

Hi guys,I would like to know how can I read PWM (duty cycle) generated from stm32?And how I can read Pwm generated from 1 stm32 send to another stm32?Sorry my bad englishTy

SPI transfer using dma request from timer

Hi,I want to do SPI transfer every 1ms without wakeing up CPU.In one SPI transfer, I want to send 10 Half words.It was possible to send SPI every 1ms with dma.But I can transfer only a half word in one transfer. What should I do ?Best regards.(Below ...

STM32H7xx RTC accuracy problems

Have several boards with problems keeping time accurately. We calibrate each board in factory test, but some boards have very large errors in the 1 Hz calibration signal and very jittery frequency readings. To make it more interesting, when there i...

What is the max voltage on a G0 pin configure as output?

It's not clear from the datasheet under what conditions pins are 5V tolerant, or what the pins can tolerate when configured as output. I'd like to know 2 things:What is the max voltage on a pin (PB0) configured as open drain? I want to have it pulled...

BDMA_ChannelX_IRQHandler being entered with ISR == 0. (H750)

I'm a bit confused what ISR==0 means in a DMA IRQ handler. I can skip it but wonder if something is configured incorrectly. Is "ISR==0" an expected and valid case or do I need to delve into settings? No error code is set, I am funneling all BDMA ISRs...
