Hello all, I made a custom board with a STM32U031 and measure the standby and standby+RTC current. The value was very high (µA), so I tried with 2 nucleo board, U031 and U083 with the PWR selection exemple code from ST. And I also check this video w...
Hi everyone,I’m planning to buy an STM32 development board to start learning FreeRTOS. I have experience with bare-metal firmware development, primarily on TI C2000 DSPs and PIC32 MCUs, but I have no prior experience with STM32.My goal is to first le...
Hi, Currently using a STM32H743X Eval kit ...it has the 6" screen on it. I've check in the CAD files for the EVAL kit but its got the gerbers BOM ect.. but no complete CAD ... as in something we can import into solidworks , so were able to model bit...
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...
