For a project I am using a number of timers to generate and/or monitor digital signals in a custom protocol. I stumbled upon a glitch in a timer Output Compare channel which I would like to share to find whether this is recognized and if there is a p...
I have configured the STM32F030 with DMA for RX, and when sending 0x05 from a PC, I observed 0x7d on the debugger. Upon checking HAL_UART_GetError() during reception, it showed HAL_UART_ERROR_FE. I am unsure about the cause of this issue. Could you p...
I'm encountering an issue with the ADC on my STM32H745ZIT6 microcontroller when reading voltages from a power supply. Here's the problem in detail:I'm using the ADC to convert analog voltages from a power supply into digital values. However, I've not...
Hi, I am attempting to obtain readings from the LIS2DTW12 accelerometer on board, utilizing the SPI interface and an STM32F098RCT6 microcontroller.I’m accessing the ‘who_am_i’ register along with the high and low registers for the x, y, and z axes. ...
Hello, My STM32G030F6P6 is working fine with the power supply from Laptops USB Port. I am just running simple I2C Scan program. When I power up the STM with charging adapter it is not able to show me the i2c scanned devices on serial monitor. I am us...
I am trying to run STM32H735 in 550 MHz, i had read the reference manual so write the following code.FLASH_OPTKEYR = 0x08192A3B; FLASH_OPTKEYR = 0x4C5D6E7F; if (SYSTICK_FREQ > 450 * 1e6 && !(FLASH_OPTSR2_CUR &= FLASH_OPTSR2_CPUFREQ_BOOST)) { FLAS...
I've always been a little unsure about how FIFO manages data transfer, so I ran a little experiment with a logic analyzer to understand it better, the result confused me even more.I set up OCTOSPI to transmit 128 bytes to an external QSPI memory, wit...
Hi,I need to use the STM32C011F4 multichannel ADC like I used to 20 years ago with other microprocessors. That is:Select ADC channel (0, 1, 5 or 6)Start ADC conversionWait for EOCRead ADC valueStop ADCIn this application I don't want to use DMA or In...
Hi All,We have design schematic using STM32H753BIT6 microcontroller and as of now we have cleared all EMI/EMC tests except Radiation emission. We could able to see the harmonics of 60MHz crossing the margin.We have System clock running at 480MHz, LCD...
Board: NUcleo 64-G474 I just want to read 2 channels of an ADC but am presented with a bewildering array of incredibly confusing options: Ranks, Continuous mode, discontinous mode, number of conversions, oversampling, triggers, etc, etc, etc. The em...
