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.
Hello,I'm planning to migrate from L431CCU6 to F412CEU6 MCU and as per CubeMX, all the pins and power scheme matches. But I see there is Vcap on pin 22 of F412 MCU. Is it okay to skip it with below setup? Adding this cap will need redesign and we wan...
Hello everyone I am trying to receive file form UART through Xmodem protocol I am getting file in debug mode but unable to get into run mode it showing UART Rx busy basically hanging over these function while (!(HAL_UART_GetState(&huart4) == HAL_UAR...
I’m having some trouble related to using the FMC to interface with a LCD. We are using NE1 as chip select, LCD register select is A0, 16 bits of data. When I’m scoping the signals, I’m seeing the A0 go high during 16 bit writes to 0x60000000 (comman...
