I'm tring to transmit as a slave to the master with I2C in a STM32F446RE but i can't get to it.When there is no code running on the MCU i can see the master requesting me to write on the osciloscope. But when I use this code: if(HAL_I2C_Slave_Rece...
With an STM32F764 I want to receive 33 bytes from 11 daisy-chained 24 bit ADCs via SPI in read-only mode. The received data looks okay but there are 37 to 39 bytes in the buffer. Also with other byte numbers I receive 2 to 6 bytes more than expected....
Hello,I'm trying to use both channels of the DAC on STM32L432, but I'm having a very annoying issue: channel 2 only goes up to 0.5V! I think I've configured both channels correctly, because both channels output voltage that changes with my code... b...
I tried upgrading the firmware on the STM32 F446RE board by accessing the usb-dfu. I used DFU-UTIL library for it. But as it turns out, we won't be able to upgrade the firmware using usb-dfu if the code already present on the board has UART or SPI or...
when pwr is down and only vbat is connected. the RTC freeze (TIME STOP) WHEN PWR IS ON IS Continue , please send please send HAL code example stm32f072 configuration thanks
Recently I switched to STM32F767ZI using LAN8742A and the LWIP library. Began to develop a web configurator based on this STM. And there is such a problem. where 192.168.97.200 is a device, 192.168.97.1 is a client (computer).During data transfer to ...
I am using the STM32F30x_DSP_StdPeriph_Lib_V1.2.3 library following instructions given in stm32f30x_12c.c for the initilization:#define I2C_SHORT_TIMEOUT ((uint32_t)0x1000) #define I2C_LONG_TIMEOUT ((uint32_t) (10 * I2C_SHORT_TIMEOUT)) #define I2Cx_R...
There have been multiple complains in the past about the efficiency of the zero copy RX and TX Ethernet buffer management. But this is not solved in any of the past releases. It is getting very difficult to build a real project out of this. I suspect...
