In the datasheet for interface with STM3117 using the i2c line, the minimum criteria for fall time is 20ns is given.Why these minimum criteria for fall time is given?What will happen if clock line fall time less than 20ns?Please explain.
Reading the SampleApp code when the client send data to the server it seems that an EVT_BLUE_GATT_ATTRIBUTE_MODIFIED should be detected in the user_notify(...) function. But if I write on the characteristic from my tablet app nothing happens...In the...
Hi, where can I find a reference manual for software development for the S2-LP?
Hello,I have started using ADC. I would like to acquire ADC channels 1 and 2 at the same time (or let say, one after the other). I have modified the provided example in polling mode to add the second channel, I have a doubt since the way we configure...
Hi,Does someone knows if the STM32F7 will be supported one day? If it's possible to adapt a code for this MCU? I have tried with a low power MCU and it actually works, but i would like to do more.. Ron
I already confirmed HAL_UART_Receive() can receive expected data. However I can't using HAL_UART_Receive_DMA.When I looked into RDR register (huart.Instance->RDR), I can see the first 1 byte of data sent from target is received. But the data isn't c...
In datasheet said:But in BlueNRG-1 Navigator i found this:
Posted on February 17, 2018 at 11:45Hi,I would like to debug a program on BlueNRG-1 using SWD interface on idb007v1 board.Unfortunately, I cannot even program the chip via this interface.Here is my configuration:1) ST-Link/V2 is connected by 20-line...
Hi,I’m using the STUSB4500. I want to have a device that can be supplied at standard 5V or at higher voltages (9V and 12V) on a single power path, so I followed the schematic of EVAL-SCS001V1 reference design. The power MOS is controller by the Vbus_...
