Hi,i am trying to use I2C1 as a slave with interruptBut after initializing the I2Ci am calling the following to set it to slave and receiver over interrupt if(HAL_I2C_Slave_Receive_IT(&I2cHandle, (uint8_t*)&bTransferRequest, 1)!= HAL_OK){ Error_H...
Hi guys, I use uart idle interrupt to handle BLE passthrough, but because ble module don't buffer data received from ble,if the baudrate is 115200bps, there will be some gaps within one packet(it should be uart transfer rate is higher than ble ra...
HI,I am using STM32L152 on IAR V8.11.2setup an interrupt IRQ but it does not seem compile since it do not exist in the map file.once NVIC_EnableIRQ execute, program will halt into BusFault_HandlerThanks!/* Includes ----------------------------------...
I'm using CubeMX to configure my STM32F413. I need 9-bit SPI, so I'm using the USART2.CubeMX is initializing the USART like this:/* USART2 init function */ static void MX_USART2_Init(void) { husart2.Instance = USART2; husart2.Init.BaudRa...
We are looking to build an STM32-ethernet interface and need some reference material to start with. It appears the STM32F107 is the available ethernet solution, correct? Are there any reference schematics or example content available to get started w...
Hi,I need to be able to change "BOOT_ADD0" and the following code doesn't work; please help.For one thing I have no idea if it's FLASH_BANK_1 or 2 that I'm interested in.Then I'm hoping that "...GetConfig" populates everything and I only need to chan...
Hi,I can find the pins of the STM32L4Rxxx in the datasheet but converting this to my hardware schematic for 144 pins is a alot of work and increases the chance of failure.Are there excel or txt files available of the device/series? so i can import th...
Hi, For my application, I need to do the following - Fire a one shot pulse on a MCU pin in response to a positive edge on the Trigger inputMake the MCU pin go low in response to an external trigger on ETR pin or any other pinIs this possible with the...
I am connecting my GPIO pin of STM32F4 of discovery board to gate of N channel MOSFET and drain of this N channel drives gate of P channel Mosfet and source of P channel Mosfet with turn on my 5VDC devices. I have also connected 2K pull up resistor t...
