Posted on May 22, 2017 at 10:49Hello,I recently bought the STM32F769I-DISCO to learn and do independent work with the M7-Cortex MCU series, and decided that the features of this board would be sufficient for such work, having special interest in wor...
Posted on May 23, 2017 at 00:19 hello, I am working with this MCU for the first time, i used AVR until today, I would like to start with a minimum circuit to do some experimenting. I m using this schematics but i don't have any idea if is goo...
Posted on April 27, 2017 at 09:20Hello all,I'm trying to setup the STM32L476RG via SPI with an external DAC (SPI clock speed: 40MHz). I used the HAL_SPI_Transmit() function to transmit a 24Bit word.After one transmission there is a gap of 2.5�s befo...
Posted on December 07, 2015 at 18:33 I have the DAC output of my STM32F44 feeding into a non-inverting op amp. Everything is working, but not real great. The problem is at the lower end, and gets worse the closer you get to zero. For ins...
Posted on May 05, 2017 at 16:11Hi community,I'm using stm32f769i-disco to make a serial communication with a Vacuum Transducer (925 MicroPirani).The 925 transducer can provide pressure mesurement output as RS232 digital value.Pressure request :Query...
Posted on May 23, 2017 at 14:17Hi there,i have the following issue:Part: STM32F446VHAL: Cube32MX, Version 1.16.0I use SAI1-A with an ADC to sample audio signals (Stereo, 24Bit, 24kHz).An Audio-DAC is connected to the SAI1-B. The SAI-B generates a wa...
Posted on May 18, 2017 at 07:38Hi, it seems that this macro has a bug - it does not clear the bits before ORing the new prescaler value in. V1.7.
Posted on May 23, 2017 at 12:35I am working with 2 stm32f4-discovery development boards, one is an SPI master and the other is an SPI slave. My packet size is larger than 2 bytes so I am forced to use DMA controllers. My slave has a buffer, called t...
