Hi,While using the SPI2 for transmitting a data in STM32F302R8, the transmitting data reflects in the DATA register only in the CPOL = 0(Low) and CPHA = 0(1st edge). In the other modes (CPOL and CPHA) the data is not reflecting in the DATA register.M...
the objective of this particular project was to transmit data frames from stm32h750dbk(discovery kit) to stm32g491re(nucleo)it is debugging and creating live expression for both of the data types in receiving and transmit end of board i have not conn...
Hello, I have a Brushless motor driver PCBA quantity of 70 such drivers and according to their original designThere are 3 units of THT Electrolytic capacitor 100V 220uf on itAnd it has 6 units of Power Mosfet 100V 107ABecause it is 100V, it can be us...
Hi,I´m trying to get a STM32H747 Discovery board together with USB Host to operate at 1.8V VDD.At 3.3V VDD_MCU USB is working fine!What I´ve done:1. Removed jumper on JP3 and supplied VDD_MCU with 1.8V.2. Removed SB10 and supplied VDD33USB with 3.3V....
I am using NUCLEO-U031R8 board and MCU is STM32UO31R8while reding reference voltage by using below code #define VREFINT_CAL_ADDR ((uint16_t*) (0x1FFF6EA4UL)) ADC1_COMMON->CCR |= ADC_CCR_VREFEN; uint16_t Internal_voltage_reference = (uint16_t)*VREFI...
I'm trying to graft an SD card onto the U5G round display development board. CN9 brings out all of the control and data lines for SDMMC2.The problem that I am seeing is that the SD device will not initialize (MX_SDMMC2_Init) due to a timeout in HAL_...
I have a STLINK-V3SET and I'm trying to comunicate with a STM32F103C8T6 (Blue Pill). I'm sucessful only when the board is externally powered by it's USB port. The STLINK-V3SET SWD or JTAG connectors have a T_VCC pin, which I now realized are an input...
found that the VDDSD pin is in the state of 2.5V during the test, when I removed the stm32f373 from the PCB, the voltage at the pad is 3.3v ,but when I soldered the chip back on, it was about 2.5V again，I would appreciate it if you could help
I just bought this board and actually i have no idea what type it is. In the box there was product card for Nucleo-32 and that is definitely no Nucleo-32. Somebody know what exactly this is? Please Help!
I have an STM32 (SPI slave) connected to a BeagleBone Black (SPI master).SPI Master Configuration (BBB):SCK = 15 MHzMode = SPI Mode 0Data Size = 16 bitsThe STM32 is attempting to transmit 2 bytes of data to the BBB using interrupt mode. However, HAL_...
