Hello ST Community,I am currently working on a project using an STM32 microcontroller, where I have implemented a feature to transmit the current date and time over USB when a user button is pressed. The USB transmission is handled using the CDC cla...
Hello,I have seven ADC channels in my design. I have probed these channels and can confirm from an analog standpoint the signals are clean, and are stable when read from using the ADC. I have read from each channel and received expected values, howe...
Hello, The cpu is STM32G0B1. I am developing the interrupt-based UART driver using FIFO and software circular buffers. The main point is, that I don't fully understand the mechanism of interrupts. I enabled two interrupts in CR3 register using RXFTIE...
What I am trying to accomplish:I have a old dimmer rack that is used just for decoration but is also a really cool piece of film history. As a project to learn more about embedded development I wanted to make it more interesting to look at. It has ni...
I am using CMSIS for STM32F446RET6 (clock speed at 180 MHz) to drive Nokia5110 LCD Module via SPI1. But, this program doesn't work. When I test with STM32F103C8T6 (using CMSIS and Clock speed 72 MHz), Nokia5110 work well. Please help me. How to corre...
I am thinking of maybe STM32G0B1CB as Slave on I2C.More precisely. For example, STM32 would monitor the voltage on 8 lines (ADC), on I2C each line would be presented with 3 registers, Low Voltage High Voltage as writing and Actual Voltage as reading....
Hello,i've implemented a routine to measure some ADC channels with the MCU STM32U5A5ZJ.After one measurement is finished (interrupt triggers after conversion) i start the conversion for the next channel.Settings:ADC conversion: Single conversion mode...
I am using the FDCAN module on STM32H753 to send messages. The message ID is always the same: 0x7DF. So I create a static Tx header: static FDCAN_TxHeaderTypeDef txHeader = { .Identifier = 0x07DF, .IdType = FDCAN_STANDARD_ID, .TxFrameType = FDCAN_DA...
Hi,I try to configure a STM32C031K6 to generate an interupt every seconds using RTC Alarm A (RTC clocked by 32.768KHz crystal).I am working on STM32Cube IDE 1.15.1. First issue was that the device configuration tool does not generate any code regardi...
Hi,whenever I try to run the CubeMX updater on MacOS, using sudo, the update will fail with:" Updater cannot write on Software Folder. It's probably due to a bad Acces Privilege."I tried to give everyone, admin and me the right to read and write the ...
