Bonjour, Pouvez-vous me dire pourquoi cette façon d'écrire lors d'une transmission I2c par interruption ou DMA ne fonctionne pas :EN: Hello, Can you tell me why this way of writing during an I2c transmission by interrupt or DMA does not work? annul...
This question is not very specific. It is quite open ended and is probably best posed to those at FreeRTOS support but I will ask here first as your support is excellent.Having spent months developing a Project that is optimized to the best of my abi...
This is a portion of my product code, but i got some problem. When an external interrupt occurs i want to start a timer and increment one variable and when timer reaches 30 seconds i want to display the variable via UART. I will provide my code.when ...
I have designed a buck converter that uses the MCU to regulate its output voltage.I am using one pin for the voltage feedback that will be used to regulate the output. However, because it has to read this pin very quickly, the sample period has been...
I have adhered to the an5200-getting-started-with-stm32h7-series-sdmmc-host-controller-stmicroelectronics.pdf document and have had a good deal of success implementing CMD53 and CMD52 comms with a slave device but there seems to be a problemThe slave...
I'm using an STPM33 digital signal processor driven by SPI using an STM32G071KBUX microcontroller. Comunication apparently seems to be ok but if I try to enable the only UART/SPI read error interrupt (into US_REG3 register) using the INT1 and INT2 as...
Hello all. I am working with internal ADC can I know what is the internal reference voltage and how to change the internal reference voltage?
Hello,I have a very basic question. In the spec of the U5 series there is this: Does that really mean that the U5 would not support talking to an SD card in SPI mode? I find it hard to believe since SPI seems to be the most basic way to interface wi...
Hi we're using STM32L412RB controller for our development wanted to know what are preferable IDE that can be used for the software development for the purchased controller.
