Hello,I am going to replace STM32F107 instead of F105 in my design, and as I see F107 has only one serial interface I2C1. In my case, I need both I2C1 and I2C2. Is there any way I can remap or define some pins as I2C2?Thank you.
I ' ve been working on a device that able to use industrial area. I must be sure that rtc clock is accurate because this device need to use RTC too much. When i researched , i did not find any code example about rtc calibration by temperature. Any su...
Hi,I have successfully configured the SPI1 with following parameters and trying to transfer a single byte but it is being timed-out in HAL_SPI_Transmit as EOT is not being set.Init.Mode = SPI_MODE_MASTER;Init.Direction = SPI_DIRECTION_2LINES;Init.Dat...
I need urgent help on STM32L071 RTC power consumption. when we enable standby mode, without RTC, the current from battery is <1uA. when we enable standby mode, WITH RTC, the current from battery is ~200 uA ? Which is too high to sustain
The reference manual (RM0402, DocID028087 Rev 7, Fig 4) shows TIM3 as a 32 bit timer. However, the in the description in Section 17.2, TIM3 and TIM4 are described as 16 bit timers.Is this a mistake in Figure 4 ?Thanks
