Hi,my first example for RS232 communication and my first problem.I have this output in the terminal:5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙ <00> 5 ''! Ë <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëåë <00> 5 ''! Ëåë <00> 5 ''! ë...
Hello, I am using the Stm32F769BI MCU.I am receiving 3 ADC channels through DMA.My problem is that debugging stops in the middle due to HAL_ADC_IRQHandler during debugging.To debug again, I must press the Run button again.I want to know why inter...
Hi all,I purchased a STM324x9I-EVAL board and I'm working on with Keil uVision5I'm using the EVAL demo firmware, downloaded from the STM32CubeF4 library packageI'd like to create a file system on external flash (in my case M29W128GL) but I see that t...
Hello ,With SPI (SPI2 in my case) I experience a delay between a wite to TXDR and the start of the SCK activity in case of an empty TX fifo. It seems to be something like 5 SCK periods, so it changes with SCK frequency but this ratio remains. I check...
I configured the SPI2 port for bidirectional (BIDIMODE = 1) and rx (BIDIOE = 0), then enabled the port (SPE = 1). According to the RM the enable should immediately start sending clock pulses out the SCK pin and read data on the MOSI pin, since it is...
I have a LSE with a freq of 32.768KHz. The cube generated code uses values for AsynchPrediv = 127;SynchPrediv = 255;These values give around ~4ms resolution. Is it possible to get to ~1ms resolution?Thanks
We are working custom board which has stm32f103vct6 (LQPF 100pin) on it. Our aim is to interface flash memory with microcontroller through SPI1 module but mistakenly board designed as PC4 pin for chip select instead of PA4 pin. Is there any other...
I run my CPU mostly (when possible) in stop2 mode. I want EXTI interrupt from few pins to wake it up. What i found is that sometimes it doesn't. ...
Good morning,We're using an STM32H7 to acquire simoultaneously 3 ADC channels 16-bit @ 5MSPS, and we store data in an external eMMC. Everything worth seamlessly as follow : 3 slave-SPI with 3 DMA to internal flip/flop buffers ; MDMA to interleave dat...
Posted on March 21, 2015 at 15:09I am newbie to stm32. On nucleo401 board i want to use six analog inputs together. ST suggest that we should use stm32cube (HAL) instead of Standard Peripheral Library. But i can't find the example of multichannel ad...
