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...
Helle everyone,I want to use the littleFS file system library that I used in my previous projects in STM32H753 Internal Flash Memory. But the fact that the block size in STM32H7 is 128K made me think a little. I normally use littleFS on 1K blocks and...
I'm developing a system with a GMS module, where AT commands are sent to the module via an STM32L0.In this case, I'm having problems with the AT+CSTT command, which was giving me an ERROR. After a lot of thought, I realized that the error was due to ...
I have an STM32L452 part in a system with multiple DMA and interrupt operations going on.The main problem I'm having right now is _sometimes_ I don't get the interrupt for DMA RX on UART4. Sometimes I do, sometimes I don't.I have been adjusting the ...
