I'm trying to read a NTC temperature sensor, but the readings I'm getting are very inconsistent and at times just way off. I have nucleo on the way but this testing I'm doing is on a blue pill.The sensor is sitting in a cup of water, so temperature ...
Dear Sirs, we have a SPI CRC problem we thried heavily to solve, but no success.We broke it down to just send one byte of data, so the CRC is known in advance and it is easy to debug.Here the description what we did:DevicesMaster: STM32F7 (SPI1)Slave...
Trying to run timer2 to set pwm signal for the BLUE LED (PA5).The MCU is STM32U083MCT6 and I used rm for STM32U083MC series (https://www.st.com/resource/en/reference_manual/rm0503-stm32u0-series-advanced-armbased-32bit-mcus-stmicroelectronics.pdf)I s...
Hi, I am using STM32CubeMX 6.16.1 with a STM32H503RB and I have exactly the same problem : RCC is configured with LL library (not HAL), here is the SystemClock_Config() function generated by STM32CubeMX : void SystemClock_Config (void) { LL_FLASH...
According to Datasheet, I2C of STM32F413VGT can be increased to 1 MHz, is it possible?
This is the pinout for the STM32F469I-DISCO and OV2640, I have been able to find pins for most of them but am having trouble:DCMI Pinout: (Pin function : Actual pin name)DCMI_D0 : PC6DCMI_D1: PC7DCMI_D2: PG10DCMI_D3: PG11DCMI_D4: MissingDCMI_D5: PD3...
Hi,I'm working on a piece of code using UART, where I need to send a byte of information right after the negative edge of that line is detected. Basically, my dev kit is connected to a 1-wire device through a simple 2 N-FET transistor for the TX side...
Hello, I have some setup variables in my app which should retained while the power is switched off. Normally I would use the dedicated Backup RAM, but the board does not have backup battery, battery socket, not a battery connector. The Backup RAM is ...
I am currently using the STM32F446ZET6 chip, which comes with 16MB of off-chip SDRAM. I have been trying to run the program in the SDRAM, but have not been successful. I would appreciate any help.
In STM32F413VGT I2C3 support Fast Mode Plus(1MHz)?I cannot find documentation
